It fits the 35, 40, 50, and 60 horsepower models specifically, so confirming your exact engine horsepower rating before ordering is worth the extra moment. The thermostat regulates coolant flow through the engine to maintain the correct operating temperature. Running without a functioning thermostat, or with one that opens at the wrong temperature, pushes the engine outside its designed operating range and affects fuel efficiency, combustion quality, and long-term engine health.\u003c\/p\u003e\n\n\u003cp\u003eThis thermostat replaces Mercury and Mercruiser part number 8M0117413 and Sierra part number 18-3640. EMP manufactures it to OEM specifications for correct opening temperature, flow characteristics, and physical fit on the listed applications.\u003c\/p\u003e\n\n\u003cp\u003eCompatibility and specs at a glance:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eFits Mercury and Mariner 4-stroke outboards, 35 horsepower\u003c\/li\u003e\n  \u003cli\u003eFits Mercury and Mariner 4-stroke outboards, 40 horsepower\u003c\/li\u003e\n  \u003cli\u003eFits Mercury and Mariner 4-stroke outboards, 50 horsepower\u003c\/li\u003e\n  \u003cli\u003eFits Mercury and Mariner 4-stroke outboards, 60 horsepower\u003c\/li\u003e\n  \u003cli\u003eReplaces Mercury and Mercruiser 8M0117413\u003c\/li\u003e\n  \u003cli\u003eReplaces Sierra 18-3640\u003c\/li\u003e\n  \u003cli\u003eBuilt to OEM specifications by EMP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eNormalized SKU:\u003c\/b\u003e 7575519\u003cbr\u003e\u003cb\u003eUPC Code:\u003c\/b\u003e 840080496412\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":54081059225905,"sku":"EMP-75-75519","price":25.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/7184\/8291\/files\/emp-thermostat-mercury-mariner-75-75519-840080496412-1237996870.jpg?v=1778583798","url":"https:\/\/www.firstchoicemarine.com\/products\/emp-thermostat-75-75519","provider":"First Choice Marine","version":"1.0","type":"link"}
