Product Details
Sierra 18-5967-1. 55-amp alternator with a serpentine pulley. Sierra identifies 1996-1999 GM V6 and V8 carbureted marine applications, including 305 and 350 CID V8 engines, and lists MerCruiser 807652T as an interchange reference.
Parts Desk Insight
Match the serpentine pulley, electrical connections and engine serial-number application. Sierra also makes single-groove 55-amp alternators, so the output rating alone does not identify the correct unit.
