Here is the low down

at 24 hrs last june it had the exhaust system from a ski-rope. ski sank and went to dealer. \
the dealer repaired i and returned it with a cavitation issue. /
returned it to dealer and dealer replaced wear ring/ was better but still not the same as before the sinking.
new wear ring started cavitating more again and i pulled it . mind you this is at less than 10 hrs on a new ring.
replaced the "new damaged" ring with a stainless one.

still having issues. i pulled the pump back out today and ound that one blade has a slightly larger gap than the other three. with this i am thinking that i may have a damaged impeller with a bent blade. it still runs out ok i there is not a load of weight onboard. otherwise it cavitates badly above 7k and out o the hole.

That sounds like it is the impeller then. You should replace it.
