A starter motor is the component that cranks the engine over to begin combustion. If it fails to engage, spins without turning the engine, or does not respond at all when the key is turned or the start button is pressed, the engine will not start. This starter motor is built for Crusader and Ford-based marine engine applications, engineered as a direct replacement that matches the original unit's fit, mounting and function.
It is a 12V unit with counter-clockwise (CCW) rotation and a 9-tooth drive pinion, fitted with a 4.5in case. The drive-end housing extends 2in into the flywheel housing, matching the original Ford marine configuration.

Frequently Asked Questions
Will this fit without modification?
Yes, this starter motor is built to match the original Crusader/Ford marine unit's case size, rotation and terminal layout, so it installs as a direct swap.
What's included?
One new 12V starter motor, ready to fit. No mounting hardware is substituted - use your existing bolts and terminal connections.
How do I know my old starter has failed?
Common signs are a single click with no crank, a slow or straining crank, or no response at all when the key is turned or the start button pressed.
How do I check I have the right rotation?
This version is counter-clockwise (CCW) rotation. A clockwise (CW) version of this same application is also available - check your original unit's rotation marking or the OEM numbers above before ordering.
