    Are you able to rev it out of the water? You might try looking to see if the cat-con broke off and is lodged in your exhaust.

    no, won't rev out of water either, trys to , but breaks up badly, likes its starving for fuel. Pulled fuel pump to check filter on
    the bottom, that was clear, injectors maybe ?

    Seriously, check out the cat-con. Last summer I couldn't get my ski above 4,000 RPM and found this once I took the stinger off:



    The thing turned sideways so it was barely letting exhaust by. Only a couple of bolts to take off the stinger and check...

    what is the whole story??? starter clutch replacement at 10 hours?

    I really appreciate the help so far,goliath, i wish it was the cat.

    Did you put the cat back in or lose it and go with a Dplate and chip?
