    95 Seadoo gts 587 crank

    Hi

    This is my first Jetski.
    I have to replace the crank (2 bad center and 1 rod bearing)

    Parts manual part # 290 886 793 for mine

    Ebay show's White (mine) Yellow, Gtx Sp, etc there are some that have 3 bearings on the output end, and multiple part #'s

    Other then the extra bearing they All Look the same (I can't find any info on rod lengths for the different cranks)

    Which years, models, crank part #'s will fit?

    Help!!!!!!

    Thanks for Any and All Help

    587 cranks all interchange the only difference is the early ones did not have locating pins on the front bearings
    Y'all know me, still the same O.G. but I been low-key
    hated on by most these &^$$@s with no cheese, no deals and no G's, no wheels and no keys, no boats, no snowmobiles, and no skis, mad at me cause I can finally afford to provide my family with groceries

    WWSRD , What would Speed Racer do ?

    The 3rd bearing on the output and the yellow engine make no difference?

    No, there are some with three bearings and some with two bearings and a spacer, the later cranks used the spacer setup , Seadoo said at the Seadoo school that it was to keep the crankcase pressure balanced on the twin carb engines, basically it just takes up negative air space in the crankcase, all of them will interchange, you would have to pull the locating pins on the front bearings for cases with no provision for the pins.

    The third part is not a bearing.....it's a 'labyrinth seal'.........a spacer.
