5.7 MCX Belt Squeak Squeel

[markmcfarland]

I just bought a 2009 XStar with the Indmar 5.7 MCX. Had to replace the alternator right away. New belt was put on then. Boat still squeaks or squeels when you get on the throttle. It was done at the dealership and seems to be tight. Any suggestions. Dealer is checking it again, putting in new O2 sensor, and winterizing as we speak. Thanks for your help in advance.

Alternator bracket isn't broken, is it? I had that happen on my boat. It looked completely normal to glance at. Squeal went away when it was replaced.
