It is built for Mercury Mercruiser outboard and sterndrive systems where the original switch has failed or worn out. This switch ensures the engine only cranks in neutral, reducing the risk of sudden boat movement during startup.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplaces OEM part number 8M0052939 for a direct fit\u003c\/li\u003e\n\u003cli\u003eSealed contacts resist saltwater and freshwater corrosion\u003c\/li\u003e\n\u003cli\u003eMechanical plunger provides a firm and repeatable shift detection\u003c\/li\u003e\n\u003cli\u003eCompact design fits existing Mercury Mercruiser shift brackets\u003c\/li\u003e\n\u003cli\u003eHeat-resistant polymer housing tolerates engine bay temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Mercury outboard engines with a shift cable interface\u003c\/li\u003e\n\u003cli\u003efor Mercury Mercruiser sterndrive units with a shift plate mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLets boaters start the engine safely from the helm without leaving the throttle in gear\u003c\/li\u003e\n\u003cli\u003ePrevents starter motor damage from cranking under load\u003c\/li\u003e\n\u003cli\u003eIdeal for saltwater marinas where corrosion attacks exposed switch contacts\u003c\/li\u003e\n\u003cli\u003eRestores fail-safe starting after a worn neutral switch causes intermittent no-crank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8M0052939\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNeutral safety switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eActuation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePlunger, spring-loaded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOutboard and sterndrive shift systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Can this switch be used on both a Mercury outboard and a Mercruiser sterndrive? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, the 8M0052939 neutral switch is shared across many Mercury outboard and Mercruiser sterndrive models that use the same shift cable mounting geometry, but verify your shift bracket style.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I know the switch is faulty? \u003cstrong\u003eA:\u003c\/strong\u003e Common signs include the engine starting in gear, stalling when shifting into neutral, or a no-crank condition that only occurs in neutral, all pointing to a failed internal contact.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":45564174532694,"sku":"ZZ3F09060","price":101.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/s-l1600_3465d670-5696-4ff8-808e-72cdea52e936.jpg?v=1789284420","url":"https:\/\/www.solidspare.com\/products\/neutral-switch-shift-8m0052939-fit-for-mercury-mercruiser-outboard-sterndrive","provider":"Solid Spare","version":"1.0","type":"link"}
