- Welcome back! In this short episode I take you along with the revival of an old 1980 Johnson Evinrude OMC 7.5 hp two stroke Seahorse propeller drive outboard motor. I found this several years ago just overgrown in the grass behind somebodies house, and recently I was walking in the saem area and remembered the motor, so I decided to pop by the house and ask if they were doing anything with it. Turns out they weren't even aware it was back there, and so they let me take it for free! Not a bad deal, from that regard! No history is known other than it sat there, exposed and on the ground for several years. The previous owner tried to get it running, but was unsuccessful and so left it to die :(. Well, now that we got our hands on it she's back on the transom and pushing an old boat around once more!
All told, this motor went from abandoned and overgrown to rippin' around the lake in approximately 25 hours. Couldn't have had more fun doing anything else!
Maybe we will explore sand casting to try and make a toroidal propeller for the unit... Enjoy! - Jak na to + styl
Wow! I finally found a man on CZcams that is more hard headed than I am. I spent an hour cranking on my old Evinrude fastwin until I finally decided it was time to clean the carb. I now have 6 different outboard motors, all old 2 stroke. Now, the first thing I do is take the carb out and clean it. They always start second pull. 😂
Project farm it first! The ol drill trick often forces enough fuel through the system to self clean em. Then if they're still gummed up after 'running' take em apart and clean them properly, which is definitely the proper way to do it, haha.
HELL YEAH. GET UP MAN. !!! Great job. I only got a beat up 9.9 myself. Redid it from scratch like yours. Found dead. For 200 .$ & revived. Runs great. Can't beat it. !
They are the greatest!
Doing this sort of thing is so much fun!
Hi Troy. Lov the vid. I've just fixed the tiller arm on my 6hp johnson. It seems you are missing two tiny plastic caps that come on the top ends of the pin you changed. They then glide in the channel of the tiller arm . 😊
Hmmm. That would make sense. Theres alot of slop in the throttle linkage as it is right now. Maybe I'll take apart my 15's throttle linkage and see if they're the same and then maybe I can make some for the 7.5.
Thanks for the tip!
@troymachovec FYI I was given a Yamaha tiller arm with the project and guess what, some of the parts are interchangeable with the Johnson 🤫 the cable on mine snapped at the end as it was forced. I replaced it with the Yami cable,fits right in no issue and the original johnson pin fits into the Yami cable😉
I've got one of these motors. Through bad experience, I learned that the water level needs to be higher than you have it when running the motor in the bucket😑. At least just over the horizontal fins. Great video!
Totally agree with you. For tests, it's okay but definitely don't run em for extended periods, or you will cook the impeller. Ideally, I'd get a bigger bucket... hahaha.
Your a lucky SOB for sure, wish I could have found that 1980 7.5hp. They were great runners although they do have a few unforgiveable engineering flaws. Please replace that water pump impeller, don't ever run these engines out of water, even for a few seconds. You will burn up the impeller. Worse yet, the rubber impeller could disintegrate and plug up your cooling system. Replacing the water pump on one of these is fairly simple job, be sure to change the gear lube as well
Great engine for sure.
Serial number is not always right. The correct age is through the model nr. (At least for Johnson) The last two letters are the code for the year. Mine sais also 96 on the serial but the model no reveals that it is from 85.
If it's older then from 1980 then the thing looks different again. But! Neither or less...happy for your find! 😅
Oh! And the mod number reveals also that your engine is a 8hp engine
Your correct! I can't remember the model no. at this point, but I think it was a mid 80's build. Ill have to correct it in the next video. Got a bunch of loose ends to fix up on it!
good job
Looking to the end I noticed there was no flow on your cooling system. Either the impeller is shot, or the thermostat needs replacing. I picked up a Mercury 7.5 for 120$, and I replaced both since I got a deal on the motor. I would do the same for yours since it runs so nice.
Your throttle handle is missing the glide pieces that attach to the cross pin.
Great job I'm working on 1983 evinrude 30 hp impeller is weak replaced it with amazon parts big mistake.
Yeah. I've learned you usually get what you pay for with replacement parts. Good luck though. They're solid engines.
Gonna like the vid purely on the fact that you are a 95 kid too.
Haha! Thanks, I appreciate it.
Should white lithium grease gon8n the handle?
Can't hurt. Id probably use outboard grease because of water resistance.
Great video. Love these
Your motor looks like an early to mid 80s model, judging by the decals on it. And you might have something stuck in the tube that the impeller pumps the water through, most likely dirt dobbers. Should be spraying out a good stream of water. Probably be safe to say that it needs a new impeller as well.
My 15 is identical to this at idle, and it has a new impeller. When it's running WOT it does have a solid stream. You might be on to something though, because I also have an old Mercury and it does pass more water than either of my 'rudes at idle.
@@troymachovec I don’t know much about Mercurys, but I’ve grown up around and had Evinrude/Johnson my whole life. However, in these times I’d probably get a Mercury. Evrinrude BRP doesn’t build fuel motors anymore, and I’m not a fan of Yamaha, Suzuki, Honda, or Tohatsu.
I just got a 8 hp same yr should push my 9 ft soft floor inflatble
I have the exact same engine here in Norway. Any idea how to change the impeller on that thing? Thanks in advance
Tell you what. Everyone in these comments is telling me I need to replace the impeller (and they're probably right) so if you send me an impeller kit ill post a video on installing it.
How’d you go about your choke, mine busted off and I don’t know that I want to go spend money on another cheap plastic one
I drilled a hole in the center of the plastic stick and screwed a washer on with a fine thread screw.
@@troymachovec I appreciate your help man
How’s the motor running now 6 months later? I have the same one. Cable inside the handle is broken where the pin inserts. Do you know what cable replacement is needed?
Honestly, I haven't ran it since the video... Got too busy with work in the summer and now all the lakes are frozen...
Unfortunately, I don’t know the part#. You might be able to solder or JB weld a sleeve onto it so you can reattached it?
I can not pull the pull cord to turn the fly wheel, it seems stucked. but if I use wrench to turn the fly wheel, it turn for 360 degree, that means the engine is not siezed. but what make the cord spinner not driving the fly wheel?
The retrieve on the ripcord must be broken. Take it apart. It sounds like it's stuck with the cord pulled and the release engaged, which is why you can turn it over with a wrench.
The lower the trim the higher the bow
Of course, you are well done, but I know from my experience that such an amount of pumping with a kickstarter is very harmful to the plastic crown, leads to wear and destruction, why couldn't the carburetor be cleaned right away? It's quite easy and fast. I myself am from Russia, your motors are very appreciated compared to the motors of the USSR, where the quality of performance was terrible, how many times I had to return from fishing on oars.
I wanted to see if the drive components were okay before buying a bunch of parts. But your right, it does wear the ripcord alot to pull it so much. If I didnt drop it in the lake it probably wouldn't have needed so many pulls.
Needs a new impeller. That one is clearly not working.
Yeah, I guess they start pumping less and less at idle as they slowly wear out. On the list for the next video!
You will overheat and blow that outboard without a new impeller
Its not ideal.
That impeller is melted and not working at all
It does work, just not much at idle. But I agree, it would be good to replace it.
Its not ideal.
Don't rev it in neutral like that you will ruin it
Noted
Honestly...you are a barbarian....but if it works for you... alright...
🪓⚔️🗡🛡🪓
Your girlfriend will not appreciate a two stroke Johnson.
Bahahahaha. True dat.
You will be lucky if you didnt just blow it all to Hell. I feel bad for that engine.
Im confident she'll be okay. I run an oil rich mixture for the first few trips out just to make sure its all running good before tuning it properly.
I can't believe it didn't explode!!!😮
