    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.

    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.

    How do you synchronize the carbs? can these motors be set up for remote control on a small Whaler?

    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

    I have the same outboard engine that locked up, I think from overheating. Do you think it is salvageable? How would you tackle it?

    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?

    • @ThatBoatGuy
      @ThatBoatGuy  6 років тому

      Cal Ripken they are good also. All depends on condition. They are still expensive motors.

    • @skolvikings5263

    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

  • @sdvten

    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.
