Sierra 18-5920 Starter Motor, Clockwise Rotation, Replaces 987811/RK122014/RA122001, for 5.0 & 5.8 Liter Ford Marine Engines

The Sierra 18-5920 is a clockwise (standard) rotation starter motor built for 5.0 and 5.8 litre Ford marine engines. It uses the same electrical connections and mounting method as the original Delco unit it replaces, so it bolts in without modification to the wiring harness or mounting bracket. The starter comes equipped with a fan and a drive pulley, and it meets SAE J1171 marine electrical standards, which govern ignition protection for starters used in gasoline-powered boats to reduce the risk of igniting fuel vapors in the engine compartment.

Electrically, the 18-5920 runs on a 12 volt system and draws 22 amps at 1.4 kW output, making it suited to the cranking demands of small-block Ford marine V-8 applications. It measures 5.5 x 10.25 x 5.5 inches and weighs 8 pounds. This starter directly replaces OEM and aftermarket units carrying the numbers 987811, RK122014, and RA122001, so it is a straightforward swap for boats currently running a starter under any of those part numbers.
