    Sucked up rocks!!!!! Help me with the damage!

    let a friend ride the ski today in a strange( not my normal) lake & he drove it under a bridge that was like 1 ft deep....he was at an idle and sucked up a handful of 1 inch rocks.....i heard the sound from his ski & yelled to him to shut it down which he did almost instantly.....being several miles from the ramp I had to limp it back......it took several start/shut offs to clear the rocks.....the ski was cavatating BAD....would just rev to 8200rpm.... Got home and pulled the pump & the damage is severe IMO.....

    --Wear ring is trashed

    --Impeller is trashed

    --Pump veins are damaged

    --Pump shoe veins are damaged

    Help me figure out what needs to be replaced or can be fixed...


    Can I remove the fins/veins from the pump shoe without negative effects??

    Can I smooth out the pump veins and be ok??

    Jerry can you get me a Riva stage 1 & wear ring If so PLEASE email me.....




    Here are some pics.....

    Torque-Your gonna need a new
    1-Stator pump assembly
    2-new wear ring
    3-New prop

    And yes you can grind out the shark teeth i had sucked a rock back in april and ground mine out,there are others on this site that have done the same thing with no problems regaurding performance or cavitation,Just be careful when grinding so you dont grind through the pump shoe.
    A dremel works best for this..Jerry carries the stage one but youl have to get the wear ring from riva,PPG,or your dealer...

    Good luck

    Holy Sh!t that is wasted!
    Ditto on that last reply:

    Best you can do is clean up the pump supprt and get new or good used...PR...

    check for cracks in the pump supprt and shoe when your cleaning that up...

    Only went to 8200 for a sec when I tried to get going....once I relized how bad the cavatation was I kept the revs down....4500-5000 ish just to get home..... Sorry for the cus in the subject...I notice things were pretty loose around here.....The pump shoe "shark teeth" have been ground down flush. going to price a new pump housing tomorrow....also going to talk to the local prop shop to see if they can weld it up.....anyone know what the pump costs new????? Do the bearings need to be pressed in???


    Can I run the stage one impeller for a while until I get the rest of the stage one parts???

    Cut off the veins in the pump area. Get some 600grit sand paper and smooth it out then do front to back strokes (like the water would flow) at the end.

    Take a dremel to the pump veins and smooth them out.

    Send your prop to impros.com and he can clean it up for about 50 or just buy a solas.

    It's not that bad, just needs some TLC. Do like PR said and check for cracks though.

    If you cut the stator viens it will cavitate badly down low. I'm sure his friend is gonna pay for it. ( if he's a friend )
