2014 195HO Impulse

[Dan Hops]

Just had my supercharger rebuilt. Took it out today. I'm down about 10mph top speed.
It cavitates on take off. Seems like it's working way too hard to cruise at about 25 mph. 7500 rpms.
Anyone have any insight or issues like this?
Or should I be looking at possible other issues. Impellar and wrsr ring are both good

If your impeller and wear rings are both fine, no check engine light (aka, all pistons firing correctly) and you're able to reach those rpms... I mean, the suspect is the supercharger. I'd check with the dealer that did the work. Not sure what else would cause this if the other stuff I mentioned is not a problem.

And I assume that when you say the impeller and ring are fine, that you've checked AFTER you've had this problem? Aka, no sticks stuck in there or other?
