🔧 Product Description

Genuine Volvo Penta 12-Volt Serpentine-Pulley Marine Alternator - Part Number: 3884950

A genuine used ignition-protected alternator for selected Volvo Penta four-cylinder, V6 and V8 petrol engines.

The alternator uses an internally regulated marine electrical design and a multi-groove serpentine pulley. Volvo Penta replacement information associates 3884950 with earlier numbers 3862613 and 3862665. Genuine and ARCO replacement catalogues commonly rate this configuration at 75 amps, although some Recmar replacement versions are listed at 65 amps and should be matched by output, pulley and mounting dimensions.
