My throttle won't turn all the way open!

Discussion in 'Outboard Maintenance' started by Mattcorrell, Jul 31, 2014.

  1. I just bought a 1989 15hp yamaha off of CL out of state where I'm working. The guy started it right up no problems. So I bought it. I got back to the job site where I'm going to store it till I get home and was excited to admire my new toy! I noticed the handle will only turn to half throttle. I took the cover off and can clearly see that it's not moving to full throttle. It seems to be binding somewhere under the flywheel. What could be the problem? :'( :mad: I hope that guy didn't pull a fast one on me.

    check to see if the timing advance is moving properly if not spray some oil up into it

    or


    get a ball peen hammer and tap around the  main body of the fly wheel  and see if that helps break it free

    if not u will have to pull the wheel and hope a good cleaning up will help

    sounds like it may have been dunked and not cleaned up properly or sat a loooong time

    holler for cut runner on here

    If its in neutral it will only rev to about 1/4-1/2 throttle.
    you have to put it in forward gear to get full wide open throttle
     
  4. That's it! Awesome, thanks cut! I see the stop now. Can't wait to get home in a couple of weeks to test it out.
