I bought a 96 GTX last year, and The ski ran great every time we took it out last summer. When I took my ski out for the first time this year, it was cavitating so bad that I couldn't get it to go any faster than idle speed. I was also getting water in the haul from the carbon seal. I tried to adjust the bellow tighter against the seal, and tried it out again. If I would just stand on it, the motor would bounce off the rev limiter at 7k rpm, and go no faster than idle speed still. If I nursed it up on plane, and then punched it, It would getup and go almost like it did last year.
I figured the carbon seal and maybe the wear ring was shot due to the water leakage and cavitation. When I took the pump and drive line out, I found a large rock lodged in one of the bronze vanes at the back of the pump. I also found a bunch of plants wrapped around the drive shaft. There was also no grease on the impeller splines. The splines still look ok, minus a little rust on them. The clearance in the wear ring is getting close to the thickness of a dime, and there are some little chunks missing out of it. The impeller is beat up a little bit. I figure its all from ingesting that rock.
The carbon seal has some wear on it. There was also a large O-ring where the bellow slides into the haul. I didn't think they had an o-ring there from the factory? Maybe the previous owner was also having issues, and was trying to put more pressure on it by adding the o-ring.
I ordered a new wear ring and carbon seal set. I was wondering if the impeller needed to be ground, or is it still ok?
