Overview

New Starter. Counter-clockwise rotation. Cast iron housing. Top mount rear entry starter. For standard rotation GM and Ford engines. Replaces Crusader RA122009, Mercruiser 50-808011A05, Marine Power 475106, OMC 986007, Pleasurecraft Marine RA122009, Volvo Penta 21129980, and Sierra 18-5902. All marine starters must be ignition protected to prevent explosion. Sierra's new and remanufactured starters are the only marine starters that meet Marine UL standards. Our starters also meet International standards as required by the European Community. Sierra's remanufactured starters all have new solenoids, drives, bushings, brushes and springs. The bodies are powder coated for greater corrosion resistance. Sierra has entered an agreement with United Technologies to market their complete line of outboard starters and components. UT currently is the OEM supplier to Mercury and OMC for outboard starters. All are 100% load tested. Our remanufactured starters are covered by Sierra's customer satisfaction warranty. Sierra has late model, hard to find GM permanent magnet starters.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
