    My winter find.

    Started messing with jet skis this year and love them. Worked on a few Polaris slh and seadoo spx and gti. Found this Yamaha and Kawasaki for cheap. Yamaha has 30 lbs pto cylinder and kawaskai is low it two cylinders. Just wanted to share my craigslist find. Yamaha is a nice looking ski. I Paid 800 total package.

    Ok both Pistons took a beating. You can see in one photo the exhaust valve is very close to the piston. This is my first yammy but I don't think the exhaust valve should be there. I may be wrong. Looks like someone took a drill bit to the top of these Pistons.

    Also there was sbt on the cyclinder head. The guy stated he had the motor rebuilt 4 years ago. So this one probably lasted 80 hours.

    My magnet stuck to the cylinder walls so I think they probably sleeved this motor. Isn't the nikasil done over an aluminum sleeve? So I should be able to bore this motor. Click image for larger version.
