Re: 1991 4.3 mercruiser alternator

Don't use an auto part as a replacement part on a boat. Will it work? Yes. Is it dangerous? Even bigger yes. They are not sealed against sparking and present a huge danger in a closed bilge/engine area where any fuel vapors are going to collect. This is the main reason there are marinized versions of alternators, starters, and air cleaners (spark arresters).
