    After about 40 hours of high speed use i get some cavitation burn. I also got cavitation burn when I used to use the plastic wear ring.

    It's something we need to learn to live with.

    another words your 40 hours = 120 hours for me!

    i'm kind of inclined to believe that the impeller shaft is not what is giving way. the bearings are piece of mind sure, but i mean think about all the power and torque in these skis and think about how thin the blades on a prop area.... any deflection or rubbing i feel lays in the weakness of the prop possibly

    according to GP, he says the High Horsepower machines are deflecting the prop blades when the clearances are tight. I`m not really sure if I have to worry about that.
    Jerry, Shibbs, How long would you say a typical stainless wear-ring would last under NORMAL use?
    Cost effectively comparison: stainless mod + 3yrs of stock rings or 6 replacements.

    I usually don`t mash it from a dead stop, I normally would roll out a little then blast it...PR...

    Providing you dont have any bearing failures the SS wear ring should last you forever.

    Absolutely, under serious load the impeller blades do deflect. The stock impeller deflects much easier than the Solas impellers.

    I had some aluminum wear rings made and put them on my two rxp's.It did not work very well.Both impellers had wash out pits on the ends of the blades (burn marks).Replaced one of the impellers with the solas 14/19,and really need to go with the double bearing mod.

    A SS wear ring should last until you: (1) suck up something in the pump..like gravel or a rock. or (2) experience a bearing failure.

    Cavitation will take its toll too if the clearance between the prop and wear ring is too great. But it will take many hours of use before enough cavitation damage is done to be noticable.
