97 GSI drive shaft issue

[Drollo42]

Alright so I have a 1997 sea doo gsi, I have had my second issue with what seems to be a drive shaft problem. I was at full throttle when it stopped thrusted and went to the rev limiter. It has a brand new drive shaft, pto coupler, carbon ring, and wear ring because this happened the first time out and I thought I had fixed it, now that it’s happened again I’m at a loss for what to do, please help!
