Hey guys, I have a 94' Prostar 205 and just got the boat summarized. Last season this started to happen near the end and now it seems worse. Well when I start the engine cold or even warm I will her the belt squeal on idle and even more when i give it gas. I usually just wait about a minute or so for the squeal to stop then give it gas and go. Could this mean I need a new belt? Before I tried to tighten it and it helped a little bit but got back to being squeal. How can I check for the alignment? And what size belt does this take?

When I had this start happening on my 93, a belt change solved the problem.

Any certain brand belt I should be using? Also what size/model belt?

I actually took my boat to a local auto parts shop and matched it to a comparable truck engine. They even installed it for me. Ran me about $10.

Or, check skidim.com or a MC dealer. Belt sets are pretty cheap.

NAPA belt XL 7420 is what fits my 94 205. Buy 2 for a spare to keep in the boat and check to make sure rusty pulleys aren't eating the belts. Check for excessive belt dust.

Also check the edges of your pulleys to makes sure nicks, in the pulley are hurting the belt .... Loose belts make noise sometimes as well

Mine was squealing last year, and I eventually noticed a very small drip from the circulating pump landing on the belt.
