    Houston - we have a problem

    WFO came by tonight to help me tear apart my piece of junk. All in all, it was in rather good condition given the fact that it was rebuilt in 2004, has 150 hard hours on it, and was sunk to the bottom of the Gulf several years ago.

    Guess we found the cause of the missing rpm and speed. Cylinder No. 3 was basically dead.

    Top ring was totally deformed. Look at the gap between the ring and the cylinder wall:



    And here is the No. 3 piston - notice the chunk missing between the upper and lower rings?



    And here's the No. 1 bearing. Look at all the chatter marks - and this is with the lightweight total loss flywheel:



    Evidence of my superior carb tuning skills:



    And here's the POS bilge pump. I hate this thing. I'm going to smash it in my bench vice tomorrow night after about 8 beers:



    More to come....

    Well...there you go.

    Wow..what do the cylinder walls look like? Did the rings even seat? That is nasty....kind of fits you though.

    Wel the easy part is done (Taking it apart and finding the problems). Now the hard part. Fixing it.and making it work correctly.
    SO did the bilage pump stop working before or after the ski sunk?

    The good thing is the motor didn't lock up and would have caused much more damage.
    Mine locked up and ruined the crank also.

    Best time to fix the ski - still cold as ice here.

    Atleast now you know! Smash that bilge to pieces using the #3 piston. Please don't hurt your neck while doing this.

    I am actually amazed it was running as good as it was last summer after seeing the #3 piston.

    I'd say you found at least one of your problems!!!

    Ditch that flywheel IMO tho.

    Good to hear from you Dukester. I've already decided to go back with the stock flywheel. I'm tired of getting stranded at MB and having to get towed to the dock.

    What on earth caused that piston problem? No signs of detonation, and no sign of the chunk of piston. I must have lucked out and it went right out the exhaust port.

    Actually, this is the very first Jetski motor that Lowell ported.
