It is a standard rotation unit, meaning it turns clockwise, matching the rotation required by these OMC Sterndrive and Cobra engine setups. The housing and internal components are metal construction for durability in the marine engine compartment environment.\u003c\/p\u003e\u003cp\u003eThis starter is built to SAE J1171 standard, the marine industry specification covering ignition protection for starters and other electrical components used in gasoline marine engine spaces, so it is designed to resist becoming a source of ignition for surrounding fuel vapors. If the starter solenoid ever needs replacing separately, Sierra offers a matching replacement solenoid, part number 18-5837, for this starter.\u003c\/p\u003e\u003cp\u003eBecause rotation direction and mounting position are specific to the engine it is installed on, confirm your engine uses standard (clockwise) rotation with a bottom mount configuration and a 14 1\/4 inch flywheel before ordering, since installing a starter with the wrong rotation will not engage the flywheel correctly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-5910\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Starter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation:\u003c\/strong\u003e Standard (clockwise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlywheel Size:\u003c\/strong\u003e 14 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bottom mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Compatibility:\u003c\/strong\u003e GM V-6 and V-8 engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e OMC Sterndrive and OMC Cobra starters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 19.34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard:\u003c\/strong\u003e SAE J1171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Solenoid:\u003c\/strong\u003e 18-5837\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999875945\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOMC Sterndrive and OMC Cobra starters\u003c\/li\u003e\n\u003cli\u003eGM V-6 and V-8 engines\u003c\/li\u003e\n\u003cli\u003eStandard rotation engines (clockwise)\u003c\/li\u003e\n\u003cli\u003e14 1\/4 inch flywheel, bottom mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e984456\u003c\/li\u003e\n\u003cli\u003e986505\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5910 starter fit?\u003c\/strong\u003e The Sierra 18-5910 fits GM V-6 and V-8 engines used in OMC Sterndrive and OMC Cobra applications with a 14 1\/4 inch flywheel and bottom mount configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5910 a standard or reverse rotation starter?\u003c\/strong\u003e It is a standard rotation starter, meaning it turns clockwise.
