50-8M0095471 Aftermarket Mercruiser Starter Motor 4.5L & 6.2L MPI | Sawley's Select Marine Parts

🔧 Product Description

Aftermarket MerCruiser 4.5L and 6.2L MPI starter motor - Part Number: 50-8M0095471

A compact 12-volt, approximately 1.4kW starter for Mercury-designed MerCruiser 4.5L V6 and 6.2L V8 MPI engines. These engines use Mercury's modern purpose-built marine block rather than the earlier GM 4.3L/5.7L architecture.

The electrical plug is positioned at the rear of the solenoid on the applicable unit. Confirm engine serial number and connector orientation because visually similar starters from older GM-based packages are not interchangeable.
