    shaft play

    i was wondering if there is supposed to be any movement in the shaft if it goes foward and back like a quarter inch movement, reason i ask is that i noticed a shiny area on the shaft right as it exits the hull, i put a screwdriver inbetween the drive coupler and it does move a little bit back but will move foward again when i remove the screwdriver, its not a loose sound or any clunking when i do it its very soft so no metal on metal, it also does not move side to side at all, im concerned if its pump bearings,

    i was out in the ocean today and i hit a decent sized wave and when i hit the gas again i had a slight vibration in the ski for a little bit but went away quickly, ran fine the rest of the day, rpm is all good at 7800ish runs strong too, just came back from service with a fresh oil change
    ski has 95 hours
    forgive me if i dont know the correct terminology im kinda new at these things lol

    real misleading title to thread, sorry just had to!

    A little play in normal on these skis' is what I was told. But you could always pull the pump and be sure

    Cool sloppy shaft

    the pump is easy to remove,done it twice.Honestly, you should buy the service manual. the money spent is well worth it considering the expensive damage that can result from overtightening bolts(stainless and aluminum are soft). Also the manual will tell you where to apply lube, loctite,etc. oh yeah, my little secret is to never get in a hurry and if you get frustrated take a BREAK. ride safe but ride hard . p.s. r n d sells the rubbers shims

    Change your bearings before it takes your engine out.

    The play is normal in fact you want as much of the gap as possible. Use a screw driver to pry it back. The day it gets snug and doesnt move or gap then consider yourself FUCKED.


    What your seeing is refered to as a "floating shaft".

    Here's a post on how to remove the pump and replace bearings. The whole thread is pretty informational, has needed part numbers, etc.
