THIS OLD OUTBOARD
RESURRECTING SMALL OUTBOARD MOTORS - Zábava
I’m new to your channel and man am I glad I found you. I just picked up a early 70s Evinrude 60hp an I am stoked to tear into her. Thanks for your uploads.
Hey. Thanks for tuning in. Have you seen the 79 55hp Evinrude yet. I'll bee test running her this week. Thanks again & Stay tuned !
@@THISOLDOUTBOARD1 I have have. Have fun out there.
Now that is one beautiful looking and sounding motor!!!
👌
Hello !! i have got this outboard from 6 years ago ,,and for me it's the best 25 hp in the world . very easy to clean , very easy to repair ,, not heavy at all ( 36 kg only ) . there is no electronics on this engine .
im not gonna change it , i've 2 outboards and im usin them bouth .
I like the sund of that old Johnson . I have a 175hk Johnson my self 95 mod . Keep op the god work ..
Hey. thanks for watching and commenting. Stay tuned !
Beautiful!!
I bet these old 25 hp will outlast the current 25s.
Great video. Thanks!
thank u
It'll outlast - an out accelerate - a four-stroke, that's for sure.
You have one of those voices that sounds like ya should be doing Mutual Of Omaha shows from back in the 70's.
I just found your videos and as a newbie i think they are great. Cant wait to ask a million questions about my johnson 25hp
Kool man thanks
@@THISOLDOUTBOARD1 i do a lot of work on the road. I work in the music industry. If i end up on tour in your area. I wanna hang out and chat it up about outboard motors and all.
Im just starting to get into learning boat motors. Is there a reason why it seems ya mostly work on Johnson/ Evenrude motors? That one ya got for .99 cents was epic. Im looking for a 9.9 currently.
@@brianwilliams4254 Hey. Yes. parts are always available and reasonably priced, where as Mercury parts are stupid expensive and harder to find on the older ones, also there is just more johnson/evinrude around. I like to think of them as the Briggs & Stratton's of outboards motors, easy to work on, dependable, and plenty of parts. I really like the Yamaha's but they just dont come around very often and they aren't cheap. If you want to learn, Heres the best place to start www.leeroysramblings.com/ . Everything you ever need to know . BTW, I loved Mutual Of Omaha's Wild Kingdom, one of my favs as a kid! Hahaha. C U when U get here and your buying the wings ! HAHA Thx again Stay tuned !
I get 23 mph out of my 1978 25 HP Johnson, almost identical to yours but on a 14ft V hull aluminum. So much fun. Mine idles a little rough so I might take a look at it. Yours is much smoother than mine at idle.
Hey. thanks for checking out my vid. I love the old 18's, 20's. and 25's. especially the 25's
25's will idle rough, compared to the 18 or 20. That's the nature of the beast.
i want buy same eletric parts .Could help me tô bring tô Brasil my friend.
Man, they were tough old motors!
Hey. thanks for watching !
THIS OLD OUTBOARD yes sir, you bet.
some had "low tension" ignition this year. Special spark plugs in this system needed. I worked at a Johnson Dealer and had alot of these pre CDI motors.
Hey. I never knew that, I love these old outboards. I've been trying to find one, they're getting harder and harder to come by. Thanks for watching and commenting . Stay tuned !
I have an old 1987 25 Merc that the mechanic I used cracked the midsection where power head bolts down. Well long story short another mechanic said scrap it , but it has sentimental value and I may slowly restore it. I know it’s a lot of money , but when this motor ran she ran for hours and hours.
Hey. you should be able to get another mid section for it, try ebay or look on craigslist for an old parts motor. hope you get it back up and running. thx, Stay tuned !
Amazing video. I have the exact same motor and year. The gear is staring to kick out under load and after so many attempts it won’t engage in forward gear. The lever will physically for in gear but it won’t even engage. Any help suggestions. I’ll check gear oil height
Hey. Check the shift linkage where it connects the upper and lower rods. It's behind that small access panel with the 2 screws in it on the side of the exhaust housing. Sometimes the brass connector gets worn and slips on the rod. If its not that then its probably the clutch dowg gear. Some guys will pull the gearcase apart and just turn the gear around, but then you won't have reverse. Hopefully the entire gearcase isn't shot. Check the schematic at marineengine.com and you can find a manual at boatinfo.no. Curious to know what you find out. Thanks for watching and commenting ! Stay tuned !
Okay I'm ready for mine to run now! D:
All I had to do is go out there and give it a shot of ether and that puppy fires right up and runs like a champ! :-) I'm hoping to get it out on the water this Sunday and see how well it pushes my MacGregor Venture 25 :-)
greetings. I have a question. I just received my grandpa's 1971 Johnson 25 hp. I took the cover off the motor and found an extra fuel line that's not connected to anything. after looking the motor over there seems to be a small brass nipple behind the carb that leaks gas when the motor is running. and there is another smaller brass nipple on the other side of the fuel filter that blows air out when the motor is running. should that gas line I found be attached to both those brass nipples? I can not find a diagram of this anywhere. and the manual doesn't mention it either. @ 11:16 in your video it looks like you have the a fuel line attached to the same nipples I'm referring to. ( behind carb and above fuel filter) Just wanted another opinion before I go any further. sorry for such a long message. any help would be much appreciated. Thank you
Hey. Yes hook it up. heres a parts look up, just pick your model www.marineengine.com/parts/johnson-evinrude-parts.php?year=1971&hp=25 and here you can find a manual www.boatinfo.no. thx. stay tuned !
good job. I just got one.
Hey. Thanks for tuning in!
Hi! Tell me please. Vertical end play of the crankshaft 1.5 mm in tolerance? Thanks!
Hey. Sounds about right but can't say for sure. Never really got that technical, as long as it didn't rattle or leak at the seals it was good to go! Best to check the manual for specks if you think there's a problem. You can get a free manual at, boatinfo.no. Thanks for watching & commenting. Stay tuned !
Thanks for all the info you provide in your videos. I have the same motor in this video but mine is a 1971. There is a black fuel line that goes from the crank case (behind and to the left of the carb) to an inlet abouve the feul pump. What is the line called and what purpose does it serve? I have the manuel for the engine but I can't find anwhere that mentions this line. Any info you could provide would be much appreciated and thanks again for the content you provide.
Hey. Thanks for tuning in. Yeah some outboards have one some don't. Weird, its an intake to bypass cover hose. I think its there as a vacuum to pull excess fuel/vapors, but I never took the time to find out which way its pulling! Hahaha. Thanks again & Stay tuned!
@@THISOLDOUTBOARD1 thanks for the reply. On my motor the fuel runs in the direction from the carb to fuel pump. Part of my hose is clear so i can see the flow. It's not a constant flow, more like pulsing from what i can see.
@@tbake4420 wow. that's weird, how does it run. those fuel pumps are funny, they have to be oriented correctly, does the outlet fuel line nipple on the pump point downward and torwards the carb. Here's a link to how they work, you may already know all this or you may not. leeroysramblings.com is where I learned everything! www.leeroysramblings.com/Rebuilding_fuelpump.htm
i didn't know how to message you personally but, do you have a wiring harness for a key ignition for a early 70's model johnson 25 horse? or any info on to get me started. i turned my boat into a stick steer and i cant find a harness anywhere.
You could just run the start button and kill switch wires to a panel with the two buttons on it so its still push button start/kill. Or pick up a key start for omc on ebay and wire them to it. you can use any wire as long as you hook them up to the proper connections on the key switch. the switch comes with a diagram and the wires you use just wont be omc color coded. the two marked "m" will be kill and the "b" will be battery and "s" will be start.
hands down the best 25s ever made
Yeah Baby !
Quick question, would you use any brand of water pump on a 25HP mercury or go with Quicksilver? It is an 1984 model.
Hey. Happy Turkey Day! I would use what my wallet said to use. Hahaha. But that was back in the day when I was flipping these old outboards and after a couple of Merc's I found out how stupid expensive parts for them were. Buy if you have a nice outboard and you only want the best than go for! Its up to you, but be sure and check out ebay, if you haven't already. Good deals there. Thats where I buy all my parts. Fast shipping too! Have a great weekend & Stay Tuned !
There was a motor that you painted the power head and I noticed you taped up the round part on top where the flywheel goes does that metal help with the spark
Hey. Thanks for tuning in. No, but the armature plate needs to turn freely. So no paint on it. Thanks again & Stay tuned !
I have the same motor and just this year I've finally started loosing throttle response and no top end speed. I'm only getting about 16mph in a 15ft terry stick steer. Any ideas where to begin?
Hey. First thing I would do is check the compression, its probably fine but never hurts to check it. Pull the carb and clean it. Sounds like the high speed orifice/jet may be clogging up. Check out my carb cleaning video. The link is in the description. After the carb is clean and theres still a problem. Give it a good tune-up, points, plugs, condensers. Check your spark that its strong on both cylinders, It may be time for new coils too. Thanks for watching ! Stay tuned !
How many twist did you do to set the carb pin after cleaning and rebuilding it
Hey. Gently screw the slow speed idle screw all the way in and seat it. Very gently you don't want to bend the tip. Then back it out 1 and 1/2 turns. That should get you up and running and then you can dial it in. Hope you're using a new slow speed idle screw retainer. You can find a manual here, boatinfo.no. Thanks again!
Yes. I agree. Timing is everything when looking for those. With all the outboard flippers you created that stuffs hard to come by. LOL. I guess no charging stat or on these old ones?
Yeah none on these
I got a 71 just like this with a boat I got. Can you tell me what are the right Ngk plugs for it. I also need carb and water pump kit. Thank you great video
Hey. Thanks. The Champion J4J are the recommended plugs. Here's the cross reference list www.sparkplug-crossreference.com/convert/CHAMP_PN/J4J.
You can find the parts you need here www.marineengine.com/parts/johnson-evinrude-parts.php?year=1972&hp=25&model=25252R.
Also check ebay for cheaper prices on parts. Thanks again & Stay tuned !
I have a 1969 25 Johnson that bagging out and backfiring when I give it throttle any suggestions
Hey. Backfire is usually the plug wires are on the wrong cylinder. Try swapping them. If that doesn't work Check your points/timing. Also check the flywheel key isn't bent and the groove in the flywheel where it the key fits is still tight on the key. If its stretched out the timing will be off. Curious to know what you find out. Thanks & Stay tuned !
I have one of these units that's surging at high rpm. Boat will get on plane everything sounds good then it starts surging to a bog. It starts sounding out of time. Or missing any suggestions? Any way I can share a video with you? Thanks!
Hey. I watched your video. Hard to tell whats going on in one minute. I dont see any water coming from the peehole, could be overheating. Have you tried pumping the primer bulb as it starts to bog? Bad fuel pump or air leak in hose. Have you seen anything leaking anywhere around the powerhead or underneath? Could have an air leak somewhere. Give it a good inspection. Whens the last time you tuned it up? Your just going to have to go through and eliminate one system at a time. I would start with the cooling system, make sure its pumping water real good. Probably wouldn't hurt to check compression too. Then the fuel system. From the tank back. It could be something as simple as the vent in the tank cap is stuck or closed restricting fuel supply. Bad primer bulb, air leak, carb jets clogging up, fuel pump. Never assume anything with these things, just because it looks good or clean dosent mean it is. What may seem like a fuel issue could be an ignition problem and vice versa. As components start to warm/heat up they start breaking down. A coil will test out good when its cold but will break down as it heats up. Take your time, its probably something simple. Curious to know what you find out. Thanks for watching !
Very cool videos! I'd like to ask your help Sir! I'd like to put a thermometer to my '72 20hp Johnson (I think the cooling system is similar). Could you please recommend, where should I drill the hole/thread to the sensor (1/8 NPT threaded Temp Sensor)
Hey. Thanks for tuning in. Well. I would think somewhere near the thermostat and water passageways. But I couldn't pinpoint a particular spot to put it without tearing it down and checking it out. Wouldn't want to give you bad information and screw up your motor! That's gonna be your call. But I like the idea. Thanks again & Stay tuned !
@@THISOLDOUTBOARD1 Thx for your kind reply! keep up the good work!
After backing the slow speed valve out 1and a half turns. How should I reattach the linkage to it.
Hey. Dont attach any thing until you find the "sweet spot" on the needle. Start the motor and let it warm up. After its warmed up, very slowly turn the needle in clockwise in 1/8th increments allowing the motor to adjust with each turn. You'll hear the RPM's start to rise. Keep going until you reach the highest RPM's just before the motor starts to cough and cut out. You'll probably have to do it a few times until you get use to where it starts to cough, we'll call it the "high" spot. Now do the same thing except counter clockwise and the RPM's start to drop, and just before the motor cuts out is the "low" side. So in the middle of the high and low sides should be your sweet spot on the needle +/- a bit. Then pull the linkage knob off the needle, attach the linkage and press the knob back on at 3:00. This should give you full range of adjustments for lean/rich on the carb using the adjusting knob. I usually end up doing it 2-3 times so I know exactly where the carb is set. Thanks for watching & Stay tuned !
Right above the fuel pump its 2 screws with a metal plate mounted and right above that its a hose running from the little vacuum hole. Is it running to the little housing right under the carb (not the carb hose) i know that runs to the fuel pump
yep www.marineengine.com/parts/johnson-evinrude-parts.php?year=1972&hp=25&model=25R72R
So, I have this very motor. Runs out great but won't idle unless I give it a little twist of the throttle. How do I adjust it???
Hey. Idle Adjustment Screw, not the one on the carb, but you may have to adjust it too. It's on the throttle control gear that turns the mag plate, It is made of plastic and usually get frozen up and wont turn, or are missing or have been replaced. Numbers 83, 84, 85 on the schematic. If its frozen up you can try and heat the metal around it to loosen it, to much heat and you'll melt it. If it's broken you'll have to drill it out, it has a stainless steel wire core, use a small bit and work it out, try not to mess up the threads so you can put a nut and bolt back in there. Also check your roller setting on the throttle cam, is the carb butterfly just starting to open when the roller is between the two marks on the cam. This is also the motors timing so be careful ! Hope this helps. thanks. Stay tuned ! www.marineengine.com/parts/johnson-evinrude-parts.php?year=1972&hp=25&model=25252R&manufacturer=Evinrude§ion=Exhaust+Housing
Hi I have and Johnson FD 16 and it is a real pain just start and idles really bad always a real hard kick back and then stop and hard to get running again after that you think you could be the read plates causing the problem or I guess the carburetor cleaning carburetors been clean to look swell inside just really have a trouble trying to get it to idle or even starting. I tried to put the little electronic ignitions in there but did absolutely the same thing as the points kicks back real hard and doesn't idle correctly
Hey. Thanks for tuning in. It's hard to say about the reeds, but it sounds like an ignition/timing problem. Kick back or backfire could be it's firing on the wrong cylinder, try swapping the plug wires and see if that does anything. Test the spark on both cylinders, use a drill to turn the flywheel and watch the spark for constant or sporadic spark. Try running it on one cylinder at at time, that will help to narrow things down. A clogged exhaust will also give it a kickback. What's the compression on it.
I have a 79 that will not start. New electronic everything as of today and still just spits when I try to pull start it. Carb is new, fuel pump, flywheel key is good, new coil packs, new powerpack, new plugs, new ignition coil, new ignition sensor, bypassed kill switch incase it was the issue. Still nothing, any ideas? Plugs are wet so it’s got fuel, also using new non ethanol fuel
Hey. Did you test for spark? Plug wires crossed. To much fuel drowning the plugs. Ground wire not grounded good. New but faulty powerpack, it happens. I would start with a spark test and how about compression, is it good? You can find a manual if you need it at boatinfo.no. Curious to know what you find out.
I like your video and I just bought a 25 horsepower motor model #25r73a in mint condition problem is I dont know how to start it. It's my first boat motor and am excited to start it.
Hey. Are you just Goofing on Me. Hahaha. Its like starting a Lawnmower! Did the Seller Start and Run it for You? Do You have a Fuel Tank and Fuel line for it? Dont Forget to Mix Your Gas and Oil 50:1 or You'll BURN it Up! If you go to my channel and scroll down to the ''From the Archives'' Playlist, You can see how to start it in most of those old videos, its easy if the motor is tuned up and in running condition. 1. Pump the Primer Bulb on the Fuel line until it is Firm, at this point you carb is full and the float closes the needle and wont let anymore fuel in the carb bowl. 2. Make Sure Your in Neutral and Not in Forward or Reverse. 3. Turn Your Tiller Throttle Handle Counterclockwise to the Start Position, this Will Put the Motor in a Fast Idle Position. 4. Pull the Choke Lever Out. 5. Pull the Rope Stater or Push the Electric Start Button until the Motor Starts. 6. Push the Choke Lever back in and Return the Throttle Handle Clockwise back to Idle Position. Sometime You have to push the Choke Lever in Very Fast as Soon as the Motor Starts or it will ''Choke Out'' and Stall. Sometimes You Can Ease the Choke Back in Slowly until the Motor Smooths Out. It's just something your gonna have to play with and get use to Once You Know Your Motor. They're all a little bit different. LMK. Thx, Stay tuned !
@@THISOLDOUTBOARD1 lol... no im serious this is real life for me... and no I dont have a gas tank and no fuel line the owner said it only needs a spark plug. So I'm learning as I go. I also need a battery maybe
@@davidbalderas1158 Hey. Wow I never heard that one before, they usually say "' it just needs the carb cleaned'' . I hope you got a good deal. So it does have electric start thats good, it sure beats pulling on those things. Anyway , get your tank and stuff and dont forget the 2-stroke Marine Oil only! NOT the stuff you put in a weed eater ! I'll help you out best I can. Meanwhile it wouldn't hurt to get a compression tester and spark tester. Cheap at Harbor Freight. Did he say when it ran the last time. If its been sitting for years its probably gonna need coils. Heres your motors parts list, www.marineengine.com/parts/johnson-evinrude-parts.php?year=1973&hp=25&model=25R73A
and heres the manual boatinfo.no/lib/evinrude/manuals/1971-1989johnsonevinrude.html#/0
also heres a great site to get started, it doesnt have 25 hp motors but they are all pretty much the same, just stick to the 9.9 and 15 horse section and youll be fine. LMK THX www.leeroysramblings.com/index.html
@@THISOLDOUTBOARD1 thats awesome thank you. I bought this motor from a friend I work with said he bought it a few years ago and never used it but he is sure it works said he found it on Facebook market also it was given to me for free he said he knows how it was when he wanted his first boat plus he just bought boat a brand new boat a few years ago said it took him 50 years to buy him something like this hes 74 years old pretty cool. Anyways I think it's a pull motor it has a string like a lawnmower. Lakes up here (Minnesota) are still a little frozen so I have time. Thank you again and for having the time to message me back. I'll sure and keep you posted.
@@davidbalderas1158 👌
Great stuff man, enjoy watching your show! I’ve got a 92 25hp, E25TEEND I believe is the model number. Seems a sluggish, not quite 25hp, pushing and 18ft d&w all-weld. Carburetor appears to be for a 20hp, is that possibly restricting hp or is this carb the same for 20,25 & 30hp? TIA
Hey. Yeah someone could have swapped the carb along the way or the high speed orifice is clogged. It should be the same as a 30-35 hp carb for that model but with a different size/smaller orifice. www.marineengine.com/parts/johnson-evinrude-parts.php?year=1992&hp=25&model=E25TEEND&manufacturer=Evinrude§ion=Carburetor. Check out my Carb Cleaning video too! czcams.com/video/401zCRctu1c/video.html Thanks for watching and commenting. Stay tuned !
Quick question...I have a 73 25hp what do you use or recommend for spark plugs? The person I bought it from told me it has the wrong plugs.....
I'm surprised by what the schematic is saying, www.marineengine.com/parts/johnson-evinrude-parts.php?year=1973&hp=25&model=25352A&manufacturer=Evinrude§ion=Cylinder+%26amp%3B+Crankcase . Its usually Champion J4C or so I thought. It is for the 72. Here's the cross reference for the UJ4J which shows the J4C's www.sparkplug-crossreference.com/convert/CHAMP_PN/UJ4J . Sometimes the J4C's are hard to get so I would go with the NGK B7S plugs. They're usually in stock. Thanks !
@@THISOLDOUTBOARD1 Thank you !! Will look at getting a few of those
I have one just like this but can't figure out the linkage for the Carburetor.
Hey. Check out leeroysramblings.com. Thats where I learned everything when I first started. Lots of good stuff and it applies to all these motors. Check out the 15hp sections. Also you can find a manual at boatinfo.no. Thats all you need. Thanks for watching and commenting. Stay tuned !
Question for you…do you know why some of the 1970’s motors had a big beefy ring gear vs thinner ones like on this motor and my 1985 and others?I am contemplating spending money to put electric start on my motor.
Hey. No clue. Those starter motor brackets aren't cheap. You can probably find a parts motor with the bracket cheaper than the bracket ! Thanks !
Are you located in FL and do you work on these? I have the same motor and I am having some issues with mine.
Hey. Maybe I can help you out. What is the issues your having?
Just bought my 1973 Johnson 25, took it out and can’t get it to go full throttle, won’t get my 13 foot boat up on plain. Runs fine and idles fine but won’t go full throttle, checked the linkage and there’s no slack, carb is being opened fully. Any information on what might be causing this would be greatly appreciated, thanks in advance
Hey. High speed jet/orifice in carb possibly/probably clogged. Clean it. czcams.com/video/401zCRctu1c/video.html Thanks for watching and commenting. Stay tuned !
THIS OLD OUTBOARD I will get started on that this weekend! Thank you for the help!
Do you have any parts available for it ? I have yeh same engine just a 73 and need the lower gear units or just the pinion gear
Hey. Thanks for tuning in. No, I only have one gearcase that I'm saving for an upcoming build. Your best bet is ebay, or look around for a parts motor on craigslist, offerup or facebook marketplace. You can find a parts motor for the same price as the gear. You might try kodibass too. He sells parts. Thanks again !
hey bud I want to put a starter on my 73 25 model 25r73a its hard to find a bracket that works, any suggestions
Hey. Try ebay for a used one or craigslist and offer up for a parts motor, 18, 20, 25hp. You need the old style, #55 and they're not cheap. Thanks for watching !

Hi there, your videos have been very helpful, however I have been battling an issue I can not seem to resolve. Exact same motor, out of the water it looks and sounds like it runs great in gear, I take it out to the water, it started out great then I lost most power and bogged down really bad, I’ve checked just about everything except under the flywheel. My bottom spark plug is getting super black very quick and wet with gas I believe. Could this be a bad coil under the flywheel?
Hey. Sounds like it's sucking to much gas and fouling/drowning out the plug, But it is possible the coil is breaking down after it warms up. Thats the problem with these things and trying to diagnose them. What may seem like a fuel issue can be an ignition problem and vice versa. So then it becomes a process of elimination. Also bogging down is not characteristic to a coil breaking down in my experience. Coil failure is usually no spark or intermittent spark causing the motor to miss and run ruff on one cylinder while the other cylinder is running fine. You can pull the plug wire off the bottom cylinder and see how it runs on just the top cylinder when the problem starts to happen. If it still boggs down then you know its not that coil. Also get a spark tester or better yet a timing light is best, you can see them in daylight, they are cheap on ebay, and test it while its running bad, then you'll know for sure whats going on. Make sure all your ground wires are making good contact and tight. So if it turns out the spark is bad you'll have to go under the flywheel, you could just have a bad condenser and burnt points. Maybe time for a good tune up! Once you've eliminated the ignition system and theres still an issue then move on to the fuel system. Sounds like fuel pump is good, I would go after that carb. Float could be sticking and needle not seating flooding out the motor. Float height/position is very important. There are two positions for the float, high and low. You can find the specs in the manual at boatinfo.no. When the motor is pulling to much fuel in, the bottom cylinder is going to get most of it. You might want to start with the carb, its easier. If the carb/parts check out okay you may have a reed valve issue. So like I said, its a process of elimination, and never assume anything with these things, just because it "looks okay" dosent mean a thing. Curious to know what you find out. Thanks for watching ! Stay tuned !
THIS OLD OUTBOARD thank you so much, I’ve taken the carb out and cleaned it but didn’t really give much thought to the float being an issue, it was moving freely but I’ll give it another look as I have done more research since then and have a better understanding of what it does. I currently have coming in the mail, brand new coils (2), condensers (2), head gasket, gasket for carb, and exhaust housing gasket. Don’t know that I needed all those but figured what the heck it couldn’t hurt. Well I needed the head gasket because I pulled that off last weekend to look at the pistons. Was told not to run without replacing. When I had the carb off I took the piece off behind that and looked at the reed valves and they were all beautiful. Reason I was thinking the coils is because I figured maybe that bottom plug wasn’t firing and that’s why it came out wet, but it could have been firing, then got flooded and stopped sparking. That float is sounding more like the issue now.. or some kind of fuel over flow, because I took it out a month ago and had no issues (which would mean I was getting spark to both plugs) following weekend I took it out, it ran great for about 20 minutes then just dropped speed and started bogging out of nowhere and never picked back up. Anchored up and checked my brand new plugs and the bottom one was as black as could be and wet. So fuel overflow is sounding pretty promising. Sucks I just bought all that stuff but hey they been on there since 1972 so won’t hurt to replace anyway.
@@jeffreybehrmann4114 Thats the best way to go. thx
THIS OLD OUTBOARD hey just wanted to let you know, after replacing the 2 coils and condensers, my problem has been solved. Don’t necessarily think I needed the coils, found that the one running to the bottom plug was barley making contact inside the little rubber boot where the coil meets the Ignition wire, snipped back a little of the rubber casing to expose fresh metal wire, shoved it in and got good contact. Running great now 🤙🏼 thanks for your help
This is the motor that was stuck and you unstuck it using a hammer and a wooden block on the pistons? Did you hone the cylinders or just clean 'em? New rings or old?
Hey. No, this is not the motor, this is a 72, 25 horse from years ago. The 68, 20 horse you're referring to I got this year and yes it probably will need honed out. Stay tuned ! thanks
hey guy , i know you can help me , i got a johnson 115 hp 1994 and the 4 carburator with idle screw upper in the carburator .How many turn have i to do for a good start .THANKS A LOT
Hey. Thanks for tuning in. I wish I knew, could be 1.5 = initial turns, could be 3. I don't have any experience with 4 cylinder outboards. Yet! Hahaha. I'm working my way up though. Probably best thing would be to get the omc manual specific to that year/model. Sometimes you can find good deals on used ones on ebay. And try Kodi Bass here on youtube, he'd probably know.

Awesome video, awesome knowledge, thank you for sharing!!! - I have '71 version(25RL71S), from one days to the next starts ok, sputters a bit, shakes too much I think...next day, pull until my arm falls off, wont start, had out on the water today started fine, sputters a bit, shakes, give her throttle (forward controls, no tiller) she dies out, fuel pump?, fuel lines...cant find the OEM fuel pump version for the '71 ...any other ides ideas if you have time?. Thanks - Greg - Montreal Canada
Hey Greg. Thanks.I've had my arm fall off a few times too. Hahaha. I dont know if you just got this motor or if you've had it for awhile. Either way sounds like you need to go back to basics. Super tune up! Compression test, good even compression between the two cylinders. Fuel system, from the tank back. Air leaks, Fuel pump pumping, Fuel getting to plugs. Big fat spark. Clean/new points, new condensers and coils. Carb smoking clean, slow speed circuit smokin clean, most people miss the slow speed circuit, high speed jet/orifice smokin clean. I've got a carb cleaning video if you need to check that out. Hard starting/idle would be your slow speed circuit. You can get a fuel pump on ebay cheap! Search this number on ebay 0382875. They're not oem but I've never had a problem with them. Free manual at boatinfo.no. Thanks for watching !

good video, but why or how did you know the seal was bad?Can't see it without tearing it apart.I have heard of these upper and lower seals going bad and having running issues.
hey. on this motor i new it was bad because when i pulled the ignition and plate off to clean it the seal wasnt holding any of the ''cleaner'', then double check it by spraying wd40 on it and see how long it will hold it. if the wd40 was leaking past the seal then i knew it wasn't ''sealing''. capiche

Have a Johnson 25 as well but a 97 model, wouldn’t start on the water after running great all day. Sounds like a sucking sound coming out of the carb and a lot of black grease deposits on the bottom of the housing. Any trouble shooting advice for me, rather not spend an arm and a leg
Hey. First thing I would do is check for spark. Black oily stuff is unburned fuel mixing with carbon deposits and dripping down. It can also happen if your trolling alot and not running the motor at high rpms every once in a while to blow it out. If you were trolling you could have fouled out the plugs too. A new set of plugs is a lot cheaper than a power pack or stator. If everything just went dead then thats what you'll be looking at. Check for spark, get new plugs and check all of your ground wires, make sure they are tight and making good contact. Hopefully it will be something easy like that. There are ways of testing powerpacks and stators. You can probably find videos on youtube. You can find a free service manual at boatinfo.no. Check out the troubleshooting sections. Ebay is good for new and used parts, but with used ignition parts you never know how long it will last. CDI electronics has pretty good prices. Curious to know what you find out. Thanks for watching and commenting.
THIS OLD OUTBOARD thank you so much I got to messing around a switched the plug wires and it started to this gives me a good starting point thanks a ton
Can u please help me indentify an old evinrude outoare 2 stroke?
Hey. Thanks for tuning in. If there's no ID plate on the transom mount then check the powerhead for the small silver round plug, it's about the size of a quarter. It should have a model number and serial number on it. Sometimes it will only have the serial number and it is useless. If the plug is missing or doesn't have the model number on it the only thing you can do is search pictures and try to match the hood decals, hopefully its the original hood. Also depending on the outboard, paint color can help identify it. Post a video of it on your channel and I'll take a look. LMK. Thanks again & Stay tuned !
One last question. When you pulled your lower unit, what position do the upper and lower rod suppose to be in
I usually leave it where the screw/bolt is the easiest to take out of the connector. Putting it back together is a different story, you'll see what I mean depending on which end you leave the brass connector on.. Sometimes the rod dosent want to slide back in easily and line up for the screw/bolt. So you'll have to shift it back and forth until its lined up, thats when a pair of needle nose pliers comes in handy! But there are those times when everything goes smooth and comes together nicely. Its just one of those things you learn by doing a few times. Thanks again.
THIS OLD OUTBOARD so if the rod is in reverse the lower unit need to be in reverse. If in neutral the lower rod need to be in neutral. Same as in reverse?
@@delanie8615 Yeah.
Loveyou
hey i have a question, i just put new points and condensor on a 72 johnson 25. if the gap is too big will the motor still run or not at all.
Hey. it will/may run but the timing will be off. to small of a gap and the plug will fire to soon, to big and it will fire to late resulting in poor performance. Thanks for watching & Stay tuned !
@@THISOLDOUTBOARD1 what's the gap ment to be set at I have a 1975 25hp and I would like to check the timing gap as it runs but has a carry on randomly were it will cough sneeze kinda backfire iv just got it and hadn't been ran for a while so giving it a hall over its a clean good looking engine for its age
@@kaisloetjes483 hey. Thanks for tuning in. The Gap should be set at .20 on the highest point on the cam. Thanks again!
Hello,ive got a question,have a 71 Johnson 25 hp, replaced all ignition components,carb rebuild,plugs,my issue is,its studders in certain spots thru the RPM range,wot it runs fine,is my timing out of sync?
Hey. Thanks for tuning in. Hard to say without watching it run and even then it could be half a dozen different things that would cause that. Carb clogged, air leak, reed valves, float setting, timing, too rich, too lean, compression. At this point it becomes a process of elimination. But don't be fooled. There is also a point when throttling up that is very normal for it to studder. Thats when its transitioning from low/mid range speed to high speed. The carb opens up and sucks in more fuel from the high speed jet and it takes a couple of seconds for it to catch up, then starts to haul azz. It can been tweaked a little to smooth it out but not much, it's a 2 stroke! People don't usually drive them at that awkward speed anyway. So it never hurts to go through it and double check things. Make sure that carb slow speed circuit it surgically clean, those tiny holes, inside the top of the carb throat where the slow speed needle meters the fuel, they need to be poked with a tiny wire, carb spray is not enough, some people use guitar string or a bread tie. If just one hole is clogged it will screw things up. This seems to get overlooked a lot when cleaning carbs. Double check the points, they're also prone to vibrating and loosening up and the gap changes. One cylinder could be firing later then it should. You can also try and run it on one cylinder at a time, like its 2 separate motors. This will help narrow things down if one cylinder is missing. Take your time, be patient and never assume anything with these things. Thanks again & Stay tuned !
@@THISOLDOUTBOARD1 ok thanks for your feedback,you 'da man ' I watch your videos all the time, as far as setting the timing or the Link and sync that's adjusted on the magneto cam and the carb throttle linkage correct? Also I've broken the pull rope twice,not sure if I've got shitty rope or something
@@jimm1975 Hey. Thanks. Yes. Once your points are set to the highest point on the magneto cam then set your cam follower or "roller" to the timing marks on the throttle cam. The carb butterfly should just start to open as the roller hits dead center of the two marks. Hope its just a bad rope! Thanks again !
Thanks again for your advice, really appreciate it,I'll try what you've suggested,il stay tuned for the next video!! 😎

Hey. I usually go to marineengine.com and look up my parts numbers and check there prices. Then I'll look up the part # on ebay for availability and best price. Ebay is great for used parts too. Sometimes I'll order the parts by price or distance, the closer the part is the quicker the shipping. Most of the time. Hahaha. And when searching part numbers on ebay, search the number twice. Once with the "0" at the beginning of the part number and once again without the 0. Some ebay sellers dont use the 0. You can get the carb for around $15 on ebay.

Whats a '71 25 electric start Johnson worth in good condition went through like this one fixed whatever was needed?
Hey and Thanks. Assuming your selling it... It depends. Its the ''art of the sell'' ! In my opinion a good outboard like these should bring an easy 500+, especially in good condition, good compression, etc. But what drives the price up is pictures/video of all the work you did on it. Buyers love to see all the work done and time spent on the motor they are interested in. Anybody can just say they cleaned the carb or changed a seal but the proof is in the pics ! Back when I was flipping these things on a regular basis, They would sell fast and I was asking 700+ for them and getting it, but that was 6-7 years ago now. These 70's 25's are few and far between around here these days. Rarely do they pop up, and they dont fly off the shelves like they use. But there is one that was posted on craigslist a week or so ago and he's asking $600. Now, If your buying one thats a different story, be careful, Be Sure to check the compression and the oil in the gear case. Anyone selling an outboard will expect that. Dont be afraid to low ball him, its just part of the process! Hahaha Thanks again. Stay tuned !

I got a 74 johnson 25hp. The throttle is very stiff and only turns so far. Any ideas?
Hey. Yeah. Start at the throttle handle and take it apart and clean it all the way back to the throttle control arm. Remove all old grease. If its still stiff pull the flywheel and plate off and clean it too! Must be clean and smoooooth. Thanks for tuning in!
Awesome will do
I’m needing my 1969 Evinrude 25hp motor repaired. I live in Oregon. Do you know anyone who might be able to help? It ran fine this past year until last weekend. The motor all of sudden stopped in full throttle in the bay and would not turn over anymore. I am getting spark from my plugs. I am getting fuel in the carburetor.
Hey. Thanks for tuning in. No I don't know anyone in Oregon. Are you getting fuel to the plugs? Pull the plugs out and check after you try to start it, are they wet or dry. If dry, fuel is not getting there, then you need to find out why. Carb clogged? Air leak? If wet then the fuel is getting to the plugs. But how much? To much will flood and foul out the plugs. Carb float and needle? Weak spark? Choke not opening? After you eliminate the fuel system of any possible causes move on to ignition. Weak spark, failing ignition parts? Good strong spark but no fire. Timing is off. Flywheel & flywheel key. Loose, bent or sheared key? So this is just a few things to look at. What may seem like a fuel issue could be ignition and vice versa. It's a process of elimination. It's best to have manual. Try ebay for a good used omc manual. Curious to know what you find out. Thanks again and Stay tuned !
@THIS OLD OUTBOARD Great video. I have the same motor 1974 Johnson 25hp [25RL74M] and I am unable to open the carburetor throttle fully from the tiller handle. I have not been able to find any information online or in the service manual to adjust this. Could you please give me some ideas to fix this issue? Thanks
Hey. Theres really is no adjustment. It needs to be very clean and lightly greased . Your brass gears may be misaligned or the teeth are broken. The handle could be worn out inside where it connects to the shaft. The Magneto plate could be worn and sticking. The throttle gears may be misaligned, loose, worn. The only thing you can do is check all moving parts from the handle back to the Mag plate and replace anything worn or broken. www.marineengine.com/parts/johnson-evinrude-parts.php?year=1974&hp=25&model=25RL74M&manufacturer=Johnson§ion=Exhaust+Housing Thx, LMK Stay tuned !
THIS OLD OUTBOARD thank you so much for the quick response. Do you know when/how the idle adjustment screw should be used? The is the screw located on the side of the handle and wrapped within a spring. Also, can you recommend a service manual that you would use? I think mine is incomplete.
@@dmnutex Hey. That screw will keep your carburetor from closing all the way and stalling out the motor. When you screw it in you can see the roller move up on the throttle cam on the mag plate.

I have a 1969 Evinrude 25hp. Is it similar to this Johnson? The other day, I ran into a problem and I’m not quite sure what it is. I was going full throttle and all of a sudden it just revved high instead of going high speed. I don’t think I hit anything or didn’t sound like it. I opened the prop, and the shear pin was a bit bent so I replaced it with a new one and still sounds the same. Any ideas?
Hey. It sounds like a spun hub. Take the prop off and make 2 marks on the inside back of of the prop, one on the prop and one on the hub and make sure they are aligned with each other. Run the motor and "spin the prop" creating the same situation, if the marks aren't aligned then the hub is bad. If the marks are still aligned the gears are slipping in the gearcase. Thanks !

Its made of rubber and squeezed into the prop, once it comes loose, it spins inside the prop, usually due to age it just gets loose. Once it loosens up, usually at high speed it spins inside the prop and the prop cant keep up with it, thus a "spun hub" and high revving.. Do your homework ! Search spun hub for a detailed description of what I said to do. It's easy and you'll get a better understanding of what I'm saying.

Hello I have a 76 Johnson 25 with electric start. I have 125# of compression great spark and fuel getting to the cylinders but it will not fire. I’m out of ideas would you be able to point me in a possible direction? Any help would be appreciated thanks.
Hey thanks for tuning in. Maybe it's getting too much fuel to the cylinders and flooding the plugs out which could mean the float needle not seating or float needs adjusted. Or the slow speed idle circuit in the carb is clogged and it's pulling a lot of fuel straight from the high speed circuit in the bowl. Only other thing I can think of would be the timing is off but it should at least fire/pop/spit/sneeze. You could drain the carb, pull the plugs out and clean them, shoot a little fuel in each cylinder, bump the starter just to get the fuel mixed in the cylinders, quickly put the plugs back in and crank it. It should fire, but you have to do it fast! It may be better just to do it on the top cylinder, it's faster just doing one. Curious to know what you find out. Thanks again !
Thank you. I’ll let you know how it turns out.
Ok, I have rebuilt the carb it’s got new needle and seat gaskets etc. the float is set parallel with the carb body as was described, I cleaned all the passages including using the “ puddle method” you described in a video for the low end jets they drain very rapidly as was demonstrated. I tried placing a little fuel in the top cylinder as you described and it barely popped. It seems as if the timing is off but as far as I can see with gear selector set to neutral the armature plate plate set against the stop. The crank is rotated till the point is against the SET position and then points gap is set to .020. Other than that timing appears non adjustable. But it feels like timing is too far advanced but shy of adjusting point closer how would you retard the timing? Thanks so much for your help.
@@nathanielhite3738 Ok so the points are set, now you have to set the synchronization or "link & sync". This is critical. The cam follower or "roller" needs to start opening the carb butterfly just as it hits between the two marks on the throttle cam as you throttle up the handle. It should be in neutral, rotate the prop by hand to be sure it's not in gear. You should be able to go all the way to full throttle when in neutral. Ok so slowly turn the throttle handle, the throttle cam on the plate should make contact with the roller at the first mark, as the roller, rolls between the two marks the butterfly should start to open as it passes the first mark. Adjust the linkage as needed. It's also best to adjust the idle stop/adjustment screw so the roller sits just before the first mark on the cam. Usually these old motors don't have the nylon idle stop/adjustment screw anymore or they're broken or all froze up. You'll want to replace/fix that if need be. Number 84 on the schematic, I usually just replace them with a nut/bolt. Without it the plate will want to float back down an kill the motor. www.marineengine.com/parts/johnson-evinrude-parts.php?year=1976&hp=25&model=25652E&manufacturer=Evinrude§ion=EXHAUST+HOUSING. Keep your slow speed needle valve at 1 & 1/2 turns out from seated, that will get you started and you can dial it in later. At this point, connect the fuel line and pump it up, pull the choke closed, set the throttle to start position and fire it up! Be ready to push the choke handle in as soon as it pops, these things flood fast. At Start position it will rev high so be ready to bring the throttle back down too. LMK how it goes!

Awesome video, please help me out I'm a novice on working on outboards, I have a 1971 Johnson 25hp I bought that is stuck in reverse do you have a video that shows how that mechanism works and is supposed to look like on them? Thanks and cant wait to make mine prrr like yours .
I've got several videos of torn down gear cases but best thing to do is. There are three screws on the gear case two big ones with flat head screwdriver slots and one with Phillips head screwdriver slot do not touch the one with the Phillips head because you will disconnect the mechanism inside the gear case. Open the top flat head screw and take it out this is the Overflow for the oil. Then get a pan or something and open the bottom flat head screw and see what comes out. If it's nice fresh oil or it could be old crappy oil then you're in pretty good shape if it's rusty water you're screwed. Probably going to need another gear case. Also there is a website it is called leeroy's ramblings. Check it out. Plenty of good information there. It doesn't matter that it's a 25 horse they're all about the same configurations. Just look at the 15 horse sections exactly the same thing as a 25 just a little smaller. Hope that makes sense anyway let me know what happens. Thanks for watching and commenting. Stay tuned!

First off, thank you for your videos, I've learned so much about my old outboard.
I need some help; I have 1969 25hp evinrude, I was doing some carb adjustment and noticed while I was running it with the hood off there was water dripping from the bottom of the head. It soon filled up enough to drain out of the 2 small holes. After inspection the core plug is missing on the bottom of the head. I took the thermostat off and could shine a light straight through the hollow part from the top through the bottom. I'm sure this isn't great and I plan to replace the plug. But any idea what could have caused this?
Thank you!
Hey. Thanks! Wow. Never heard that before. I did a search but nothing about outboards it was all inboards and freeze plugs popping out from the water freezing in the block. I guess that can happen on an outboard too. If it didn't freeze it could be just old age, a little corrosion, and some vibration over time it worked its way out. Might need a little JB weld on it when you put it back in. Thanks again & Stay tuned !
I have a74 Johnson 25 hp, good spark, fresh gas, resealed lower unit. Still can't get it to start. I need to buy a pulley to clean the points and replace crankshaft seal. Good video
Hey. Thanks. Yeah you'll be surprised at whats happening under the flywheel. Thanks again !
Hello, I'm in apopka florida and just got the same exact motor with a boat. Can you fix mine or take a look at it ? I'll pay whatever I need.
Hey. Right now I've got my hands full and a couple people ahead of you. So its going to be awhile. But you can check back in a few weeks if you still need somebody. Thanks !
@@THISOLDOUTBOARD1 will do thanks, and I commented on the wrong video. It's the 1972 20hp johnson seahorse
Have you ever tried turning a 35 Evinrude into a 50? I have a carburetor has the same bolt pattern as a 35 but it's from a twin cylinder 60 I'm just wondering if I can make it work and if you've ever had any experience in this? Also if you like any more parts I've got three or four 25 couple of them run three or four 35 one of them runs I need to build one for myself and then the rest I'm going to get rid of so if you're interested text me back let me know my name is Jimmy thank you
Hey. Thanks for tuning in. No I've never tried that size. Check the high speed orifice/jet size on those carbs, the 35 may be bigger if the 60 was using two carbs. You can always get a bigger jet for it. I think I'm good on parts right now but a friend of mine is looking for a 35 carb, what years are the 35's and how much would you need for it? Thanks again & Happy Holidays !
What's the part # for the upper crank seal?
HEY. TRY THIS. www.marineengine.com/parts/johnson-evinrude-parts.php?year=1972&hp=25&model=25R72R
Thanks man, that's really helpful being able to see the break down of everything and part #s!!
👌
Just pull the seal an take it to a bearing shop; they'll replace it based on OD, ID, and thickness. Most oil seals were made to metric dimensions; 7mm thickness is common.
are you for hire i live in St. cloud and have a Johnson 25 hp 1969 would like to have looked over ?
Hey. No but I appreciate you asking. Truth is I barely have the time to get my own stuff done.Maybe one of these days I'll get caught up. Thanks again
Here's a Q I've had for a few years: For a number of years, Evinrude and Johnson built identical 18 HP motors. Somewhere along the line, the Johnson became a 20, though I've never seen an Evinrude 20 of that time period. Both DID make the souped up 22 cubic inch 25; Evinrude called it a Sportster. So Evinrude was selling 18's an 25's. Johnson was selling 20's an 25's. Is that correct?
I think that sounds about right, I never really gave it much thought. They used that power head for years on all those outboards. I believe you can get a little history on it from leeroysramblings.com. thx
I have a 20 seahorse. Runs great
Yeah now if I could only just get my 18 horses to run like that😂 most the time the fuel pumps out and it's missing and crapping I sure like that push button start on that 25 though when you pushed it it fired right up like that I've got to find the mountain in a starter for mine and install a solenoid wires but we can get her done I tried some Nova chips in it and it did the same and ran the same with the Nova. So I took them out and put the points back in there still doing the same thing. And I know the Jets are clean because they're justable and I took him out and clean them. And I have j6c spark plugs in that's the FD 16. Coils look like brand-new maybe I have a bad one. But all the engines the 18 horse the Johnson all have a mean misfire at the idling I like the way that 25 that you were running the air was running very beautiful point gap 20 + 30 plug gap
Yeah that engine I think that I have the FD 16 I think it's like brand new compression about 130 lb each cylinder
Hello your video Very much was pleasant did not find information anywhere How to adjust on Johnson 25,360 cubic centimeters the engine How to expose ignition you could not adjust to share information
Hey. Sorry you didn't find what you were looking for but this is not a ''How to'' video. Here is a couple of links that should help you find the information you need. boatinfo.no/lib/evinrude/manuals/1971-1989johnsonevinrude.html#/0 , www.leeroysramblings.com/johnson_magneto.htm . Thanks. Stay tuned !
thanks I found that looked for to you all good
@@fourshouse8441 👍
Well I just got me one of those 25 Johnson seahorse outboard motor needs a lot of work I need some kind of wiring sheet I'm missing a bunch of wires and stuff some kind of wiring diagram I guess is what I need
Hey. boatinfo.no/
I have another Johnson 18 horse on a boat in Nevada I live in California and it seems to have the same problem too a hard kick back sometimes that I don't then it shuts off and won't start again after that it's 18 horse of the same way I believe it's 18 horse FD-16
Wow. thats strange, 2 motors with the same problem. Crazy right.
I want that joker ...
Thanks for watching . Check out my other outboards too.
How much for the boat ?
I stole it for 300
Any idea how fast it was goin thanks just got same one
Hey. around 7:37 looks like 24mph on the gps. which sounds right from what I remember. 24-26 on my 15' Duracraft with these old outboards. Great motors. Thanks for watching and commenting. Stay tuned !
THIS OLD OUTBOARD thank you man I must of missed it can’t wait to c it go to
Are you interested in buying a mercury 9.8?
Hey. Thanks for tuning in. No thanks but thanks for askin!
PERFECT MOTOR TO BOAT MATCH.
It's exactly what I imagined. I think it will be good. Thanks , Stay tuned !
@@THISOLDOUTBOARD1 just like the engine
Man give me some tips, I have one just got today
Hey. does it run? Did you check the compression, If the compression is good You're halfway there ! How bout spark, Have any ? Anyway Give me an idea of what you're working with, And I'll be glad to help out anyway I can . Thanks for watching and commenting. Let me know !
Bought me a 50hp mercury 4stroke fuel injection I’ll never own another 2 stroke again
Hey. Cool man! Thanks for tuning in!
we can say an outboard At this age a good mechanics that can be used today?
thanks! i think. hahaha. check out my other vids too. too = THIS OLD OUTBOARD ! Thanks for watching!
I bought an evinrude of the same model I want advice from you. You are a great mechanical expert.
NOT REALLY. BUT I WOULD B MORE THAN HAPPY TO HELP, IF I CAN! THANKS AGAIN !
Can I get your pm about a motor I want to give you
Hey. Cool, what size is it?
I just bought a 35 horse for two hundred bucks so I could take the starter off of it and I wanted to do the ignition and everything else. But I don't think that the flywheels going to work out I don't know which flywheel put on it for the electronic ignition. Heard me before I said I tried to put Nova chips I tried to put some other chips not exactly sure where the timings at. With the Nova chips it started up and ran for a couple of minutes and died. But I know it's still firing so why put a ground wire on the timing play down to the block with the chips I don't know where the timings kicking at. I guess I'm going to get my battery out my and check if haha you think. Cuz the parties not happening yet. But it's getting closer. Putting a billion on a think it was a 8225 horse carburetor flywheel all the ignition stuff and everything and the intake manifold play just no reads late but I think it all fit on my 18 you think it'll fit on my 18 just don't know if the Reed played as the same
Forget those chips, they're good on smaller outboards. Go with original parts you'll be happier. Thanks again !
I'm thinking that I need to rebuild the flywheel magnets is there a special way that that has to be taken care of. And I was watching CZcams and they said if you weld right next to it it recharges them. I mean weld like right on it but don't well the flywheel. My mig welders the only thing working right now I'm I prep a rag around it put some metal real close to it start welding up a storm see what happens. Just wondering if you heard of anything about that or something is better 🤔
@@rickmarcum3643 dont weld the flywheel! it will be out of balance. I've never seen or heard of that or seen one with weak magnets. If you think they're weak get another one used from ebay.
that motor runs fine on that boat because the cavitation plate measure is 17 -18 inches not 15
Hey. I'm pretty sure it measures 15, nowhere near 17-18. did they even make a 17-18 shaft? hellifino. hahaha
I thought some older hondas were offically 17 inch shaft
I have a jhonson 25hp is well but consumes me almost 20 lts that I can asere year 1999 that chiquer takes
HEY! OK- DIDNT QUITE GET THAT, BUT COOL. I THINK?
I have a 1973 runs like a top starts easy.
Hey. Yeah, I wish I still had this one, and few others like it that I flipped ! They are getting harder to come by these days. Thanks for watching and commenting . Stay tuned !
I've got a 72 evinrude 18hp that runs like a top
@@docholiday9786 👍
STRONG YOUR GOING TO BURN THE PAINT OFF THE BOTTOM OF THAT BOAT
👍 Check out the 83 25 hp Evinrude with the 35 horse carb. It smokes ! I put it on this jon boat. I actually just got back from running it. Holy moly macaroli, its a screamer ! Stay tuned !
You know card kit horns condensers all the electrical stuff fuel pump
I dont see a 35 horse for 1963. I have the 28 hp RX-11 I call it the Beast
