Starter Motor for Mercury Marine 40HP Outboard Engines

Fits Mercury Marine 40HP outboard engines

This is a direct-fit replacement starter motor built to OEM specifications for Mercury Marine 40HP outboard engines. It is a complete, ready-to-fit unit engineered to match the form, fit and function of the original equipment, so it bolts straight in place of the original starter with no adaptation required.

The unit runs on a standard 12-volt marine electrical system, turns counter-clockwise (CCW) and uses a 10-tooth drive pinion, with a motor housing length of 4.119 inches, matching the specification of the original starter fitted to these outboard engines. A longer motor housing version is also produced for closely related applications, so confirming the 4.119 in housing length against your original starter is the best way to make sure this is the correct variant for your engine.
