High pitch squeezing at high speeds

06elitev · June 29, 2020

I have a 2006 elite v C4 air warrior and I have noticed above 30mph there is this high pitch squeal. Wondering where this might be coming from? I am new to this boat but the previous owner took great care of it and it was serviced often. Appreciate the help.

I previously had the same when surfing (rpms 3000 for 20 mins). I changed the belt and it solved the problem. Of note, the belt looked perfectly fine. Could you associate your sound with a belt?

Possibly. Which belt should I check and replace?

Replace both that way you know you know have a fresh set. Also if your engine has a belt pulley check and make sure it appears to be working properly. They can at times be weak links.

replace with OEM belt, I ran a aftermarket belt and had squeaking which led me to believe I had bearings going out. Changed back to factory OEM belt no squeaking.
