    Got Rocks!!

    Well I did it!! after 2 1/2 years i finlly misjudeged the shoreline and got rocks, shut it down a split second later, put on trailer, removed a bunch of rocks from pump. Went home pulled pump and prop off and removed some more.

    The damage-Missing the backside (towards the nozel exit) of alot of the pumps sharks teeth viens, Pump veins were slightly bent and broke on the edge near impeller I took a file and removed loose material and filed down bumps in the water flow to make them skinny and smooth again. we are talking less than 1/4 inch bites in the veins.

    Repalced wear ring eventhough it still looked good.

    Prop seems to be ok with no dings or cuts but might be bent slightly

    However went back out and I seem to have a rrr rrr rrr cavation sound during hole shot or like hitting rev limiter but I dont think i am.

    So questions are
    Pumps sharks teeth.. are they that important
    The slight pump vien damage is it bad bad
    if these two things are not that critical then its my impeller what should I do send it to Improvs for compelte re-spec, buy new one ??

    Thanks

    Your gonna have to remove all the sharks teeth now that there are some that are damaged..you either have them all or remove them all..Missing or broken teeth will cause it to cavitate,could be were your rr rr rr is coming from...I had the same thing happen last year to me and i removed them all..filed them down smooth to match the pump tunnel and have had no bad or negative results.

    I would also have the prop checked if it was me..Just for a piece of mind

    only thing worse than sucking up rocks is forgeting about the rocks in your pump and firing up yer motor while ski is on the trailer.....and shooting said rocks at yer buddys nice shiny truck....lol...
