Last summer my rx lost a counter shaft bearing and toasted the case . So i was original was going to drop a factory short block in it from seadoo only to find out that they are unavabile now. So i started the process of collecting parts to rebuild my motor that only had 90 original hours on it before the bearing gave up. I ordered a new wsm crank for it last week. the new crank arrived and 3 out of the 4 end bearings on the crank feel rough and noisy. So now i am debating just to order 4 original seadoo bearings and press them on or send it back for another crank. The bearings on it make me nervous since they are unmarked taiwan top notch quality. so now i am not sure which direction to go in. the jet is not run hard. mostly just low speed cruising around our lake. i just hate doing jobs twice and i am more then capable of rebuilding the motor my myself i just hate junk after market parts.. I do not have the tools for rebuilding the crank myself so that i am at the mercy of somebody else.
