‘04 RXP-X cavitation at high speeds

[Seadooguy124]

Our rxp x just hit the water again, and we discovered that while at top end speed (67-71 mph) there was some light cavitation/loss of power. I figured it was just an issue with not being able to suck in as much water as at low speeds, but figured i would post here to be sure nothing serious was wrong. Thanks!

What is the clearance between the impeller and the wear ring?

Unsure. Spoke with my main mechanic i use and he did not replace the plugs when he rebuilt the supercharger, so we will change out the plugs and see what she does
