Sierra 18-5919-1 Starter for Late Model GM Engines, 14 Inch Flywheel

The Sierra 18-5919-1 is a 12-volt marine starter engineered for late model GM engines using a 14 inch diameter flywheel. Built specifically to withstand the harsh conditions of marine use, this starter has been re-engineered from Sierra's most popular starter design to hold up against water intrusion and the constant vibration and moisture exposure found in inboard and sterndrive engine compartments. Upgrades over earlier designs include a stronger connection between the solenoid and commutator brushes, an upgraded planetary seal, and a reinforced clutch gear spring, all aimed at extending service life and improving reliability when starting is critical.

The housing is finished in black and the unit is constructed of metal for durability in a marine engine bay. This starter is rated at 55 amps; for applications requiring higher output, Sierra offers a 65 amp upgrade option under a separate part number. This starter is designed for late model GM engines with a 14 inch flywheel and is not intended for permanent magnet starter applications, which use a different Sierra part number.
