I’m getting my alternator rebuilt and was looking to replace my work out alternator belt. My local marinas are telling me the part number is discontinued? 57-49756Q 1 V Belt. Can anyone tell me if this is the case or if there is a replacement belt number?? 1998 Mercury 225 EFI S/N 0G679798. Anyone run into this issue? Or is it just up here in Canada? Thanks.
