Serpantine Belt- HP500

Looking for a serpentine belt for my boat. Boat is in Havasu and I am at home. I have the part number and was hoping to go into NAPA or any auto part store to see if they can cross reference it but not having much luck. Anyone have any experience?

Part # is 57-807755-4

doing a search online with a cross reference came up with Dayco 5060880 from Autozone.

I think its an 88 inch belt correct?

Thanks for the info I will check it out. Also assuming I can take the belt off and take it into a parts store to measure.
