As the engine warms up, the thermostat opens to allow cooling water to circulate, protecting the powerhead from overheating during operation. This part is a direct replacement for the Yamaha 67F-12411-01-00 thermostat and is built to meet or exceed the performance of the original equipment part it replaces. It fits Yamaha F75-F250 outboard engines from 2005 and up. Maintaining a properly functioning thermostat is essential to preventing overheating damage to the powerhead, and replacing a worn or stuck thermostat is a routine part of outboard engine maintenance. The 18-3632 is manufactured by Sierra, a long-established name in marine engine and drive parts, with products engineered to withstand the demands of the marine environment. This thermostat is sold individually and is intended as a like-for-like replacement for the original Yamaha unit.\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 18-3632\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Thermostat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282360818\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha F75-F250 outboard engines, 2005 and up\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e Yamaha 67F-12411-01-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha F75-F250 outboard engines, 2005 and up\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha 67F-12411-01-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3632 thermostat replace?\u003c\/strong\u003e It is a direct replacement for the Yamaha 67F-12411-01-00 thermostat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Yamaha outboards does the 18-3632 thermostat fit?\u003c\/strong\u003e This thermostat fits Yamaha F75-F250 outboard engines built 2005 and up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3632 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-3632 is a Sierra aftermarket thermostat built to meet or exceed the performance of the original Yamaha 67F-12411-01-00 equipment it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3632 thermostat weigh?\u003c\/strong\u003e The Sierra 18-3632 thermostat weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many thermostats come in the package?\u003c\/strong\u003e The Sierra 18-3632 is sold as a single thermostat unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3632 thermostat?\u003c\/strong\u003e The UPC for the Sierra 18-3632 thermostat is 808282360818.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace my outboard's thermostat?\u003c\/strong\u003e A worn, stuck, or faulty thermostat can cause an outboard engine to run too hot or too cold; installing the Sierra 18-3632 restores correct coolant regulation on covered Yamaha F75-F250 engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3632 include a gasket or housing?\u003c\/strong\u003e The Sierra 18-3632 is the thermostat component itself; the dossier does not list an included gasket or housing with this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho manufactures the 18-3632 thermostat?\u003c\/strong\u003e The 18-3632 thermostat is manufactured by Sierra, a supplier of marine engine and drive parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the 18-3632 on a Yamaha outboard older than 2005?\u003c\/strong\u003e The Sierra 18-3632 is specified to fit Yamaha F75-F250 outboards from 2005 and up; fitment for earlier model years is not confirmed.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988155707611,"sku":"SIE-18-3632","price":31.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3632__40508.1655149723.500.750.jpg?v=1785188547","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-thermostat-for-yamaha-outboard-67f-12411-01-00-sierra-18-3632-fits-f75-f250-2005-up","provider":"Good Vibes Marina","version":"1.0","type":"link"}
