This 12V 80A alternator is a high-quality aftermarket replacement for Yanmar 6LP and 6LPA marine diesel engines. It cross-references Yanmar OEM alternator assemblies 119773-77201 and 119773-77200 and is supplied under Recmar SKU REC119773-77201. Designed with an internal regulator and a double-groove pulley, it’s intended to restore correct charging performance when the correct match is confirmed.
