2009 Seadoo rxt 215 loss of power

[FountainRxt]

I have a 2009 rxt 215, with 129 hours on it. All maintenance has been done by the dealer. The sc was rebuilt at the 100hr mark, along with oil change and new spark plugs. I was riding it one day and previously the machine would run the desired 70mph and i was actually running close to that speed when i all of a suden felt a noticeable loss of power and now will only run 60ish. No funny sounds, currently pulled the wear ring out and it looks to be in better shape than I expected, and yes i have changed close to 10 wear rings over the years so im sure its not my main issue, but will be replacing it anyways to eliminate it. My mind tells me to inspect sc area and everything that i can see appears to fine. Any ideas on what else it could be?

All air hoses tight?

Did you notice any loss of RPM or just loss of speed? No RPM loss probably drive train. RPM loss probably engine/supercharger.

If it’s not drive train or something obvious like spark plugs, a hose or oil overfill, leak down test probably next step.
