Spinning up/Cavitation on the line???
I am a CC racer and have just finished my ski, I am getting lots of cavitation off the line when going from idle to WOT.
It hits the limiter at least 3 times before it hooks and by this time I am a boat length down on the holeshot. It has a new wear ring (stock) and 15/19 (non R), pump seal is good.

I still have one, its in fairly good condition. I have heard that the pressure of the pump when you hit WOT can pull the carbon ring back and draw air causing cavitation also, anyone heard this?

I haven't got any sharks teeth any more
One of the les driveshaft seals may help?
I'm going to change the bearing in the pump first

i just put a zip tie in back of the carbon ring below putting more tension on the carbon ring this morning, i was starting to see a slight black mark inside the hull
