50-8M0147039 Aftermarket Mercruiser Starter Motor | Sawley's Select Marine Parts

🔧 Product Description

Aftermarket Mercury/Mariner/Tohatsu/Suzuki/Johnson outboard starter motor - Part Number: 50-8M0147039

A nine-tooth 12-volt starter used across selected small and mid-range outboard platforms shared between Mercury, Tohatsu, Suzuki and BRP/Johnson. The Mercury 50-8M0147039 reference has been replaced by 50-8M0188334 and cross-references directly to Tohatsu 3C8-76010-1 and BRP 5032026.

This is an outboard starter rather than a MerCruiser inboard starter. The shared application list spans two- and three-cylinder two- and four-stroke engines, so the original number and mounting must match exactly.
