I was gonna say there's bound to be off the shelf parts that's exactly the same as the dealers but at a fraction of the cost. Your just paying for the Yamaha name. When it was leaking I was thinking was the head tightened down to specs and I'm glad to see it was :D another nice job.
I have this same outboard, '92. I also had to replace this seal and took a while to find the right dimensions. Im having an issue with acceleration. It shakes and makes a bouncing as if it runs on one cylinder when I give it throttle . Idle is okay but I need to play with the choke to get a smooth idle. Coils seem fine and fuel pump seems to work after checking it while running . Compression is fine. I keep adjusting the jets but to no avail. Any thoughts? Thanks for your always informative vids
I have same motor that I eliminated the oil injection so I just mix oil and gas myself .the motor runs good but occasionally coughs when idling?? Had it to a Yamaha mechanic who could not figure it out? Any ideas ? Motor has under 25 hours on it! Thanks
Probably a fuel issue whether it be dirty carb, bad fuel pump, dirty lines, dirty filter, bad gas tank, bad gas tank line, etc Or could be a misfire which could be a lot of things as well
what could cause a 25ob to choke up and cut out when going through seas, once the boat slams down once or twice this happens it’s never happened before any input?
"I rebuilt the motor myself" and NO, the head gasket does not seat both ways, it should have been glaringly obvious that the bolt holes in the gasket didn't match the head. Attention to detail goes a long way. Accuracy>speed
Nice vids every time. I have a question. My 25hp yamaha 2-stroke makes weird light knocking noises from under the starter, like something is vibrating. Could that be that bearing in this Video ? And what can I do to solve it? Thank you!
I have a chance to get an 87 yamaha 25hp, doesn't start, but good compression, probably need to clean carbs, are these earlier models as good as the later ones? What's a good price to pay for it?
The coil will fail if you keep running the engine without spark plugs and grounding them good if for just a test you need to put spark plugs in both coils and ground them good
What in tardation..... Between the backwards gasket, crazy glue and inserting the new seal with a hammer and trucking it with nothing keeping shit out of the carbs, you guys are certifiable bone heads.
Hi my experience 25 hp yamaha is a very bad Outboard motor ever bild by yamaha to meny problem and very bad fuel consumption we ask yamaha please stop manufacturer this engines
Y'all need to invest in some adjustable inline spark testers. It's one of my most handy tools when working on outboards.
Would love to have a beer with you guys. Tons of knowledge, but also having a good time. That's the way it should be.

Again you proved you're the Jedi Master of outboards!
Finally!! That Boat Guy teaming up with Chris-Fix... "Hey guys!!!"...
So you run a none run in 2stroke with a leaking crank case seal? Itl be leaning out man, to much air not enuf fuel oil? Really?
Nice video and good work my friends
Dang those yami are tough!
How do you synchronize the carbs? can these motors be set up for remote control on a small Whaler?

Great channel! I've been watching for a while now.
Is there a part number for that seal?
I have the same outboard engine that locked up, I think from overheating. Do you think it is salvageable? How would you tackle it?

Why not invest in a spark checker?

Nice repair job
I'll make sure not to buy a motor from your friend
Nice vids every time. I have a question. My 25hp yamaha 2-stroke makes weird light knocking noises from under the starter, like something is vibrating. Could that be that bearing in this Video ? And what can I do to solve it? Thank you!
Will a 2019 lower unit fit on a 1993? It's a 25hp.
Hi, i hawe some problem with my yamaha 25bmh, i check carburator and gas hose, it wont go longer then 20sec. New sparks, fuel filter its ok
Check your fuel pump and your whole fuel system
Nice video. would love to work on a few outboards like this

Cal Ripken they are good also. All depends on condition. They are still expensive motors.
What would the 87 go for running in very good condition? Thanks for your vids, I'm learning alot about these motors.
87 40 hp Mariner/ Yamaha most dependable motor I've seen
What outboard school did you go to?
How much do you sell a 9.9 motor for?
Hey Eric still need some advice on that lower end unit?
what is the lower unit doing?
eric edic it looks likethe previous owner hit something so I want to replace the shell
The coil will fail if you keep running the engine without spark plugs and grounding them good if for just a test you need to put spark plugs in both coils and ground them good
All you need to do is use a caliper and measure the seal. Buy a non yamaha seal that is the same dimensions and type.
150$ for a bearing is nuts.
Smoke the joint after you put the outboard together and it runs not before lmao
Re- use the gasket 😅😅😢😅😅😅😢 lol
What in tardation..... Between the backwards gasket, crazy glue and inserting the new seal with a hammer and trucking it with nothing keeping shit out of the carbs, you guys are certifiable bone heads.
Oye una pregunta me puedes conseguir un cuarenta Yamaha
Send me your address and I'll bring my boat tomorrow, I pay good. I just want to fish dude.
Seeing you always repairing motors but you live right next to neighbors aren’t they bothered by noise
Invest in a tripod for your camera.
Ha nice job
Hai 👍👍👍
You do not lose compression from the crankcase that is blow by from warn rings and pistons
Its a two stroke so it needs pressure in the crankcase!!
Hi
Hi my experience 25 hp yamaha is a very bad Outboard motor ever bild by yamaha to meny problem and very bad fuel consumption we ask yamaha please stop manufacturer this engines
These are some of the best motors ever
Lol are you okay bud?
Wrong, I got the 90hp and the 20hp. bulletproof motors. These 2-strokes Yamaha's are some of the best outboards ever made
