It seals the mating surface between the thermostat and its housing, keeping coolant flow contained and preventing leaks that can lead to overheating. This gasket is the direct cross-reference equivalent of Yamaha OEM part number 62Y-12414-00-00, so it installs as a straightforward replacement using the same mounting points and sealing surface as the original equipment part.\u003c\/p\u003e\u003cp\u003eAs part of Sierra's outboard cooling system lineup, this gasket is intended to be replaced any time the thermostat is serviced or replaced, since a reused gasket can lose its seal integrity. It is a lightweight, single-use component sold individually (quantity of 1 per thermostat).\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 18-0835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thermostat Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 62Y-12414-00-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Yamaha 2-Stroke Outboard Cooling System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282265441\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Engine:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha 2-stroke outboard engines (cooling system \/ thermostat housing)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e62Y-12414-00-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0835 thermostat gasket fit?\u003c\/strong\u003e The Sierra 18-0835 is designed for Yamaha 2-stroke outboard cooling systems, sealing the thermostat housing on these engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-0835 replace?\u003c\/strong\u003e It replaces Yamaha OEM part number 62Y-12414-00-00, making it a direct cross-reference for that gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 62Y-12414-00-00 gasket the same as the Sierra 18-0835?\u003c\/strong\u003e Yes, Sierra part 18-0835 is the equivalent to Yamaha OEM number 62Y-12414-00-00 and can be used in its place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this thermostat gasket weigh?\u003c\/strong\u003e The 18-0835 thermostat gasket weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets are included when ordering 18-0835?\u003c\/strong\u003e One 18-0835 thermostat gasket is included, matching the quantity of 1 per engine listed for this application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the thermostat gasket on a Yamaha 2-stroke outboard?\u003c\/strong\u003e The 18-0835 gasket should be replaced any time the thermostat is removed or serviced on a Yamaha 2-stroke outboard, since reinstalling a used gasket can compromise the seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0835 gasket come with a thermostat?\u003c\/strong\u003e No, 18-0835 is the gasket only; it does not include a thermostat as part of the package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a thermostat gasket like 18-0835 actually do?\u003c\/strong\u003e It seals the joint between the thermostat and its housing on the Yamaha 2-stroke outboard cooling system, preventing coolant leaks at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-0835 a genuine cross-reference part or a generic substitute?\u003c\/strong\u003e It is sold as a direct cross-reference replacement for Yamaha OEM number 62Y-12414-00-00, matching that part's application in the Yamaha cooling system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0835 thermostat gasket?\u003c\/strong\u003e The UPC for the 18-0835 thermostat gasket is 808282265441.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988085911771,"sku":"SIE-18-0835","price":4.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0835_lg__38602.1558121050.500.750.jpg?v=1785329185","url":"https:\/\/www.goodvibesmarina.com\/products\/thermostat-gasket-for-mercury-outboard-replaces-27-14318-2-27-14318-3-sierra-18-0835","provider":"Good Vibes Marina","version":"1.0","type":"link"}
