Premium PMGR High-Torque Marine Starter

Upgrade your marine engine's ignition system with this heavy-duty PMGR (Permanent Magnet Gear Reduction) starter motor. Engineered to provide higher torque with lower battery draw, this 11-tooth unit is a direct replacement for older, bulkier 9-tooth starters found on GM-based Mercruiser, Volvo Penta, and OMC engines.

RELIABILITY: Designed with an offset bolt pattern for the 14-inch (168-tooth) flywheel, ensuring a precision fit and smooth engagement every time you turn the key.

Key Features

✔ High Torque: Gear reduction for fast cranking
✔ 11-Tooth Drive: Replaces 9-tooth for better engagement

Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured by 4Boats to meet or exceed original equipment (OE) standards for fitment and performance.

My old starter has 9 teeth. Will this 11-tooth starter fit?

Yes. This 11-tooth PMGR starter is the modern superseding design for the older 9-tooth Delco units. It is designed to work perfectly with the same 168-tooth flywheel and provides better cranking reliability.

How do I know if I have a 14-inch flywheel?

If your starter uses the offset (staggered) bolt pattern where the two bolts are not in a straight line, you have a 14-inch (168-tooth) flywheel. This starter is specifically for that configuration.
