    Rpm will not go over 5000?


    This is my first post here so be kind.
    I need some help.
    I have a Kawasaki Ultra 260 from 2009 with 100 hours that will not go over 5000 rpm. It just chokes when reaching 5000 rpm but the engine doen't stop. The rpm drops and i can again rev it to 5000.
    The ski just came back from service wich included oil and filter change and cleaning of SC and intercooler. Also some gaskets and the SC belt was changed.
    After the service I rode the ski for about 30 minutes and it ran great. But the suddenly with a full throttle application it just cut out and died. I restarted without problems and continued running it a bit closer to the shore. Then after ca 10 minutes it will not rev over 5000 rpm as described above. I stopped running it and found that it was more water in hull below the engine that it used to be?
    What can be the problem with my ski?

    Take it back to the Dealer, as they screwed some thing up, sounds like you may have an exhaust leak, which is letting water in the hull and choking the motor with exhaust fumes...May try riding it with the seat off and see if you can see a leak and if the fresh air lets it run better....

    Ok, thanks.
    Any other bids as to what it might be?
