50-44369A1 Aftermarket Mercruiser Starter Motor | Sawley's Select Marine Parts

🔧 Product Description

Aftermarket Mercury/Mariner outboard starter motor - Part Number: 50-44369A1

A 12-volt permanent-magnet direct-drive starter for selected Mercury and Mariner inline three-cylinder carburetted two-stroke outboards. This ten-tooth, counter-clockwise starter is primarily associated with 45 Jet and 50-60HP three-cylinder outboards rather than MerCruiser inboard engines.

The starter body, mounting ears, pinion position and overall length must be compared with the original motor. Some early engines use longer 50-65436/50-66015-style starters that are not physically interchangeable with the compact 50-44369A1 replacement.

⚙️ Key Features
