  • Jet ski is bogging down HELP!!!

    I have a 2001 Yamaha GP800R and it has great top end but when i gas it sounds as if its about to stall. It just grumbles and doesn't move anywhere but if i feather it i can get it to 15 mph then it will take off. I don't know if its a carb issue but i was reading a thread and they talked about a wear ring that was bad and they get no low end but it sounds as if the engine doesn't give of power in the low end.

    Is the Powervalve controller working ? Its called YPVS.
    This has a major part to play at takeoff speeds.
    You can hear it going thru its back+forward operation when you stall the motor.

    Additionally, when was the last time you serviced the carbs ?
    No matter how well you freshwater flush the motor exterior after use Salt water corrosion can be worse than you think.
