2001 XP cavitation
I just replaced my impeller and wear ring. After 30 minutes of riding my machine died and would not crank. I towed it in and later that night it started up. The next time I put it in the water it started to cavitate and within 10 minutes it got very bad and the motor screams but the ski struggles to get up on plane. Once it does eventually get up on plane it starts to perform much better... I pulled the wear ring and impeller and the look fine... Motor is making power but not putting it to the ground..drive shaft related?

Did you install the NEOPRENE SEAL between the pump and shoe ?
The engine stopping is a worry !! Did you find the reason why it stopped?

I had this problem once. Turned out to be the through hull fitting being cracked and sucking air into the pump from the engine compartment. I'd take a look and make sure it isnt cracked.

Carbon seal is leaking. Its the little boot between the rear of the hull and the driveshaft. If your ski is in the water, pull back on the boot and you will see water come into the hull. That is how the boot operates, like a spring pushing forward on the steel shoulder on the driveshaft. It can wear out....not leak water but suck air from inside the hull. If it is not messed up or cracked, a temporary fix is to loosen the rear boot hoseclamp, push the boot forward a little bit (3/16") and re-tighten the hoseclamp. That puts more tension on the seal.
Try this, with a little grease on the seal. If it helps, you found your problem. Remember.....temporary fix
