Lost top speed

[skibums]

I sucked up a rock and it sounded like plastic gears grinding. After re-starting had bad cavitation out of the hole and top speed of 54 (should run 62ish). This is a 2004 SC GTX limited, rpms are good 7200 but sounds like it is cavitating at wide open. I replaced the wear ring but still 54 is top speed and cavitates out of the hole and at WOT. Could it be a bad prop or the carbon seal?

THANKS!!!

You shouldn't damage a carbon ring because of a rock... but I would imagine that your impeller is beat, and that is why you are loosing top speed.
