GREAT INFO. Worked for my 50 hp lower end. THANKS

Have a 40hp Merc. Its 2 cylinder carburetor long shaft. Is there anything else I need to take loose other than the 4 bolts/nuts to drop very lower unit.

My 40 is a 2 cylinder carburetor, long shaft. I know how to drop it but do I need to unlock the gear shaft under the cowling . They say it's a 97 year but I think it's older than that.

Great video thanks!

Bad move -you should have cleaned all the old grease from the bearing with solvent,dried it, inspected it before adding new grease

Thanks John !!

worthless

Nice ! Thank you !

Hey John, I am hoping you can help, I have a 1998 yamaha 40hp 2 stroke, when I bought the boat it cranked and ran perfect but needed a water pump, I changed that and then when I tried to crank it I lost all power to switch and trim, I used a jumper wire to get motor down, a week later I tried to crank and while trying to crank lost power again, I wiggled the wires to switch and got power back, then it would crank and stall after a few seconds, I put new plugs and primor bulb on still the same, next day I drained and cleaned gas tank put fresh gas in and drained carb bowls, now it won't crank at all, can you help me.

Why do trailer bearings need to be repacked/replaced so often when I only need to repack my truck bearings every 80K miles or so?

Hello, I have a 75hp Johnson engine and out of the water it accelerates excellently but when I put it in the sea it does not accelerate almost at all, it goes very slowly, I have already installed new spark plugs and a new fuel tank and hoses.

Man excellent video thank you sir

Extremely clear. Well done video. Would be good to know variances from freshwater to salt for seals etc given environmental factors for maintenance schedules.

I removed my fuel/water separator and there was oil in the fuel? It’s an ocean pro 115 hp vro system engine will not stay running thought it was water in the fuel. No water? Thanks

Thanks! Where can I find fuel rate flow for outboard motors?

Hey Jhon how much you think it cost to rebuild the whole motor part wise I wish you have a video of it running and a walk around I bought mines and someone been messing with it so I don't know where some of the stuff goes I try looking it up didn't see a good video on it and different models

Thanks, this helped a ton, I'm new to outboard motor repair. My 68 6hp johnson also had a pin at the top of the shaft which I punched out and put back after installing the new parts.

Thank you for this helpful video. Is it possible to use a Speedi-Sleeve to repair the axle where it is pitted instead of changing it?

Hi John, Your reply is very much appreciated. Once I removed the 2 screws and followed the prying at the arrow points, the center portion on the Verado chaps area just popped off.. Too easy once you see how. Job all finished and new anodes installed - tricky to get to that deep anode bolt but an extension socket worked so all finished and reassembled.

To remove the rear cover You should remove cowl release handle. There is 1ea 8mm bolt that holds it on. Next remove the two 8mm bolts for the rear cover. Note the small arrows on the cover. Gently pry at the arrows and the rear cover comes off.

Sir, I have been a millwright for many years and I must say, I would consider this video and your practices to be of the most professional I've seen! You have my respect.

For salt water launches, every year service/check is a good idea. For fresh water launches, if you have replaced them and know all is good, your choice. I recommend if you buy a used trailer, replace with new hub kits to establish a base line, where you know what you have.

what why is this open I didn't open this wtf

So the 90’s tracker 40hp 2 strokes were 2 cyl while the mercury was a v4 ??

John sure you knew about this in one vid you were going to replace your axle what about this? czcams.com/video/SNKL1l567qg/video.html

Question: my rectifier was the opposite on the forward and reverse bias. Does that mean it is bad?

I have a 2002 f100 with only front half of model number plate is there any other numbers stamped on the block?

How would you test a rectifier on a 1992 Suzuki 115 outboard engine ich isn't charging the battery

Hi John, in my previous message, I have referred to lower cowling. I mean the Chaps on the leg. I cannot see the logic to remove the center section to get to the Chap bolts under that center piece . My verados are 2007 vintage. I am simply trying to replace the anode but the chaps have be off to get to the anode bolt.

Great tips. Do you also have videos of what to look for, when inspecting a fiberglass boat?

cant get the lower gear housing off of the motor

Hi John, I have twin Mercury Verado 135hp on my boat in New Zealand. Your video is excellent describing the removal of the lower cowling and I am almost there. In your video at 1.05 minutes, you say you had already removed the center section to get at the internal bolts for the cowling halves. That is where I am stuck - how do I remove the center section or is it super simple and I am just missing something?

Where does the large O ring go that comes in the kit?

You fail to mention the warning of do not lift the shift shaft, if you do it is next to impossible to get back in.

Next advice: forget air filters (most outboards don’t have one, secondly I’ve never had a fuel filter that clogged so bad fuel couldn’t make its way around (so being it’s probably water in the fuel with ethanol being the cause most of the time). That leads me to water making it through the system or ethanol derived scum blocking electric fuel pumps or creating electrolysis derived crust in the carbs. Additionally softening/melting or hardening/cracking fuel lines and carb needles. Yes ethanol can soften and or dry out and harden. Moral of the story ethanol is the bane of boaters existence

Wrong answer: like my Dad said, never ever F with Idle adjustment screws from factory settings. Always fix the problem, gummed up carb, leaky float needle (running rich, my problem 80% of the time lately), out of timing or ignition issue. Every used Briggs seems to have the idle adjust screw F’d with. With that one I think standard is all the way in then out 1 1/4 to 1 3/4 Thread. The problem with outboards factory settings aren’t always standard.

I have a 115 Mercury I don't even know set for 3 years

Hi, I have a 1998 DFI Merc Optimax 150hp and the mass air flow sensor or it’s the idle air control in the air intake on the front of the motor get covered with injector oil and it’s very hard to start when cold. When it warms up it runs great. If I take it out and clean it it fires right up and will idle but not when it has oil on it. My question is why do it have so much oil in the air intake? I know there will be some but this is obviously too much. Any thoughts?

Clearly explained, excellent video quality! A joy to watch about a task I dread. Thank you!

I have a 50 mek 4 stroke the choke not ingage and no fire have changed egnishon and kill switch on throtel still nothing

How much does it cost to rebuild one just ring and piston....if I took it somewhere

Thanks John. Excellent technical explanation and demonstration. Followed your lead and the seals are replaced on my 2002 Bigfoot 50hp Mercury. My dad (an 89 year old retired mechanic gave you a big thumbs up also. Take care. Mike and Jim , Canada.

Do have any videos for 1986 Mercury 35 hp outboard

What temp should water coming out the the motor?

Hola buenas tardes aquí desde argentina. Pregunta un motor Evinrude etec 115 año 2008 no me carga la bateria. Es rectificador el mecánico me dice que tengo cambiar emm retificador está ahí adentro desde ya muchas gracias si me puede orientar un abrazo

John, Thanks for sharing this and all you do for the boating community. It's tough these days and people like you help a lot. So.. My buddy and I tackled this job and all went well, but I didn't have that fancy driver for the locking collar that you used in the video. So I thought of "using a socket" idea, but do you know what worked best? Mu buddy said.. What about the old impeller? That worked great and came with a free cushion! I thought that I'd share, not to take away from the pro!

What size of 3bolts on flywheel ? M6 or m8?

What about the poppet valve
