Bottom Mount Marine Starter (12¾" flywheel, stern drive engines)

Commonly referred to as a "high torque, gear reduction" starter, with the straight-across bolt pattern, with ONE LONG BOLT and ONE SHORT BOLT bolted straight across from each other. This starter will work as a replacement for all sterndrive I/O engine applications with a 12¾" flywheel.

This starter is U.S. Coast Guard Approved and has the official Marine certified UL 1120/SAE J1171 stamp on the case. This is the exact same GM marine starter that MerCruiser, Volvo Penta, OMC, Marine Power, etc., use on their marine engines with 12¾" flywheels. This is NOT an aftermarket "Made in China" starter.

This will work as a replacement for:

All GM 3.0L (181 ci), 5.0L (305 ci), 5.7L (350 ci) sterndrive engines with 12¾" flywheels. This starter is commonly used on 3.0L marine engines from 1968-1998, 5.0L; and 5.7L engines from 1967-1984. If your existing starter has one LONG bolt and one SHORT bolt, then this is your starter.

Starter bolts included!
