Starter Motor for Mercury Marine 30-60HP 4-Stroke Outboard
Mercury and Mariner 30-60HP 4-stroke outboards from 1999 - 12V, counter-clockwise, 9-tooth
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 Mercury Marine and Mariner 30-60HP 4-stroke outboard engine applications, engineered as a direct replacement that matches the original unit's fit, mounting and function.
It is a 12V permanent magnet direct drive (PMDD) unit with counter-clockwise (CCW) rotation and a 9-tooth drive pinion, fitted with the nut-design drive end used on this Mercury 4-stroke range. The field case measures 4in (101.6mm) and the drive gear outside diameter is 1.654in (42mm). The same starter is used on the Yamaha-built versions of these powerheads, which carry the 67C-81800 series Yamaha part numbers.

Frequently Asked Questions
Will this fit without modification?
Yes, this starter motor is built to match the original Mercury 30-60HP 4-stroke unit's drive end, rotation and drive pinion, so it installs as a direct swap.
What's included?
One new 12V starter motor, ready to fit.
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.
Does it fit the Yamaha-built version of this powerhead?
Yes - the same starter carries the Yamaha 67C-81800 series numbers listed in the cross reference above.
What is the difference between the nut-design and retaining-ring drive end?
Mercury used both a nut-design and a retaining-ring drive end on this 4-stroke range. This unit uses the nut design; the OEM numbers above cross reference to the retaining-ring version - check your original unit before ordering.
