Loose belts, worn belts can produce noise. Do you have the ability to work on your engine yourself? Tools, time, etc?

Pulleys might need a light sanding and some new paint. I have done that in the past and it quieted them down.

Check to see if any belt "residue" is present on the pulleys, could mean that they are too tight. Or the belt is crap, or, or, or.....

Replace the belts. Mine did this last year. After a replace nice and quiet again.

Size of the belt should be on the belt. Goto any auto parts store, there is no such thing as "marine" belts. I personally prefer goodyear gatorback but everyone has their preferences.

While you have the old belts off, spin all the pulleys to see if they seem rough or hard to turn. Could have a bearing going south on alternator, ps pump etc. that can cause the belts to squeal if they are hard to spin.

I have found that sandblasting any rust off the pulleys is a good fix along with new belts.

My V belt was squeeling bad last year. Loosened bolts on the alternator and tightened it up and the whine went away.

I did that as well but it only worked for a few times out before it started to squeal again. Go ahead and replace itand keep the old one as a spare, just incase.
