It is designed to fit 35-40 HP 2 cylinder and 50 HP 4 cylinder Mercury outboard models. The starter uses high quality magnets and field coils to deliver strong starting torque even in demanding marine conditions, while double sealed housings protect internal components from moisture and salt spray for a longer service life. High quality brushes further extend durability under repeated starts. Construction meets SAE J1171 and ISO 8846 marine electrical standards, the industry benchmarks for ignition protection and safety on boats. This starter is a direct cross reference for Mercury part numbers 50-67341, 50-58788A3, 50-893891T, and 50-44369A1, making it a straightforward swap for boat owners replacing a worn or failed OEM unit. Every Sierra part is backed by Sierra's customer satisfaction warranty, giving buyers confidence in fit and function. Whether performing a routine replacement or restoring a non-starting outboard, the 18-5602 provides a reliable, marine-rated solution built specifically for the harsh operating environment of outboard engines.\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 18-5602\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 12.13 x 4.49 x 4.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 7.39 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 1.4 KW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Type:\u003c\/strong\u003e Three Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 747730043913\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e Meets SAE J1171 and ISO 8846\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Outboard Starter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e35-40 HP, 2 cylinder models\u003c\/li\u003e\n\u003cli\u003e50 HP, 4 cylinder models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 50-67341\u003c\/li\u003e\n\u003cli\u003eMercury 50-58788A3\u003c\/li\u003e\n\u003cli\u003eMercury 50-893891T\u003c\/li\u003e\n\u003cli\u003eMercury 50-44369A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat Mercury outboard models does the Sierra 18-5602 starter fit?\u003c\/strong\u003e The Sierra 18-5602 fits Mercury outboard 35-40 HP 2 cylinder models and 50 HP 4 cylinder models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Mercury part numbers does the 18-5602 replace?\u003c\/strong\u003e It replaces Mercury part numbers 50-67341, 50-58788A3, 50-893891T, and 50-44369A1, so any of these OEM numbers can be cross-referenced to Sierra 18-5602.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5602 a genuine Mercury part or aftermarket?\u003c\/strong\u003e The 18-5602 is an aftermarket Sierra starter engineered to meet or exceed the original Mercury equipment it replaces, not a Mercury-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5602 starter weigh?\u003c\/strong\u003e The Sierra 18-5602 outboard starter weighs 7.39 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this starter?\u003c\/strong\u003e The Sierra 18-5602 measures 12.13 x 4.49 x 4.02 inches (length x width x height).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat marine standards does the 18-5602 meet?\u003c\/strong\u003e This starter meets SAE J1171 and ISO 8846, the standards covering marine electrical and ignition protection safety.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat features help the 18-5602 last longer than a worn-out starter?\u003c\/strong\u003e High quality magnets and field coils provide better starting torque, while double sealed housings and high quality brushes on the 18-5602 extend service life in a marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the wattage and phase type of the 18-5602 starter?\u003c\/strong\u003e The Sierra 18-5602 is rated at 1.4 KW and uses a three phase design.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-5602 come with a warranty?\u003c\/strong\u003e Yes, the 18-5602 is covered under Sierra's customer satisfaction warranty like all Sierra parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-5602?\u003c\/strong\u003e The order includes one Sierra 18-5602 outboard starter unit; no additional mounting hardware is specified.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988218654939,"sku":"SIE-18-5602","price":190.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-5602__54859.1722511774.500.750.jpg?v=1785187990","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5602-outboard-starter-for-mercury-25-hp-4-stroke-replaces-50-888151t","provider":"Good Vibes Marina","version":"1.0","type":"link"}
