    Question Revs, but won't go

    I have a GP 800R, which recently stopped zooming. It will creep forward in idle but will not get above 5 knots no matter how much throttle you give her. Any suggestions appreciated, I am a novice rider and hopefully it is something simple. I did just have a piston replaced and the carborator rebuilt. Thanks.

    Most likely or hopefully you have something stuck in the pump. Pull the intake grate and inspect.

    Greetings Ruski

    First order of business..

    Welcome aboard the forum Ruski..

    Second.. get underneath the ski and check to see if you intake grate is all choked/clogged up..??

    After that get a torch and shine it through the steering nozzle, look for crap jamed in the prop/pump..

    Could be something as simple as a plastic bottle top or a length of ski rope..

    Either way check there first..

    Good luck

    No Debris

    I'm from Texas so it took me a while to figure out what a torch is, I didn't remove the grate but could see no debris, just a pretty silver screw. I guess there could be something I'm not seeing. Is it not engaging? The engine seems to work fine.

    Could be something stuck between the prop and the pump veins. Try inspecting from the nozzle looking forward. If nothing is there you will need to pull the pump and inspect the driveshaft spline.

    Hmmmm..??

    Hey Ruski...

    Before you do anything mental like trying to jam an object into the back of it.
    To see if the prop stops turning while the engine still turns.. DO NOT try anything like that..

    Take the intake grate off and shine your torch, sorry FLASHLITE in from underneath..

    If its still clear of any crap.. grab hold of the impeller shaft and turn it by hand..

    If it turns by hand.. then it seems Duke was on the money with it..!!

    I hope he's wrong mate..

    Good Luck
