    02 gpr pump issue?

    ok i had a thread in the general area but it kinda died out and i think i have somewhat localized my problem.

    i had my ski out riding it and got in a shallow spot sucked a rock the size of a golf ball in and lodged inbetween the pump viens and the impellar its running a solas 14/20.

    took the exit nozzle and pump off and took the rocks out.

    reassembled it and took it backout. ran great for about 10 min but after starting to get on it i lost all propulsion. ski's motor runs normal im just not getting the power to the ground.

    so i pulled the pump,exit nozzle, and drive shaft out and all look well.
    splines are fine. pump looked fine also.

    so i cleaned the **** out of the 2 mating surfaces and resealed them well.
    letting that cure for a day

    do you think this had fixed my problem? im kinda at a loss.? everything went back togather smooth.

    i am about convinced that my problem is somewhere from the drive shaft back.

    The splines in the intermediate shaft may be shot. These will go before the splines on the driveshaft. even if the impeller got damaged you would have some sort of propulsion. check out that int shaft.

    More then likely the midshaft splines flattened out when the rock got jammed in the pump. The driveshaft splines may look fine. Try and get a light up in there and inspect the female side of the splines.
