    Unhappy HELP! Water in the crank! COOL photos of a jetski not running!!!

    I have been trying to get this thing running, and haven't been doing so well. I can't wait because I know it'll knock the pants off the TS640 I've been riding. BUT, it hadn't been idling all that well and was doing the 'runaway' thing. So when I looked into things to see if it was a vacuum leak, I found what's in the pictures.

    how do I get the crud cleaned out? seafoam?

    I thought, from just looking at the plugs that the middle cylinder was running lean.
    Guess not.

    If the exhaust manifold/heat exchanger were to have a slow leak into the exhaust chamber, would that go into the center cylinder primarily?
