12V 100A Alternator Fits 1986-1997 Mercruiser 454 Mag Bravo

⚠️ SINGLE V BELT ENGINES ONLY:
• This alternator carries a single groove V belt pulley
• Late GM engines moved to a 6 groove serpentine belt
• Some 1996 and 1997 engines left the factory with either belt
• Look at the belt, one V groove means this is the right unit
• Six flat ribs means you need the serpentine build instead
