Marine engines rely on a correctly rated thermostat to regulate coolant flow through the block; a worn, stuck, or failing thermostat can cause overheating or slow engine warm-up, both of which put added strain on internal components. This kit is sized to install as a direct fit for the application it is designed for, making it a straightforward maintenance-interval or troubleshooting replacement for boat owners and marine technicians servicing Tohatsu outboards.\u003c\/p\u003e\u003cp\u003eSierra manufactures this thermostat kit to the exacting dimensional and thermal specifications required for reliable marine engine cooling, and it is packaged as a complete kit for the job rather than a bare component. It is a compact, lightweight part designed to be installed in the outboard's cooling passage where it opens and closes to regulate coolant temperature as the engine runs.\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 18-43175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Thermostat Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Tohatsu Outboard Thermostats and Gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282342012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 9-43175\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eTohatsu outboard engines (thermostat and gasket application)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e9-43175\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-43175 Thermostat Kit fit?\u003c\/strong\u003e The Sierra 18-43175 Thermostat Kit is built for Tohatsu outboard engines as a thermostat and gasket replacement application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 9-43175 the same part as Sierra 18-43175?\u003c\/strong\u003e Yes, 9-43175 is the OEM cross-reference number for the Sierra 18-43175 Thermostat Kit, so either number identifies the same replacement kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the thermostat kit weigh?\u003c\/strong\u003e The Sierra 18-43175 Thermostat Kit weighs 0.07 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-43175?\u003c\/strong\u003e This thermostat kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit include a gasket?\u003c\/strong\u003e Yes, the Sierra 18-43175 is listed as a thermostat kit under the Tohatsu Outboard Thermostats and Gaskets application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e This is a genuine Sierra-branded thermostat kit, part number 18-43175, manufactured by Sierra for marine engine cooling systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does a marine thermostat need replacing?\u003c\/strong\u003e A stuck or worn thermostat can cause an outboard to overheat or warm up too slowly, so replacing it with the Sierra 18-43175 kit restores proper coolant regulation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-43175 Thermostat Kit?\u003c\/strong\u003e The UPC for the Sierra 18-43175 Thermostat Kit is 808282342012.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the OEM number 9-43175 to search for this part?\u003c\/strong\u003e Yes, searching either 9-43175 or 18-43175 will point to the same Sierra thermostat kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the box?\u003c\/strong\u003e The Sierra 18-43175 ships as a complete thermostat kit for the Tohatsu outboard cooling system application.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988196471003,"sku":"SIE-18-43175","price":45.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-43175__50731.1558185023.500.750.jpg?v=1785188954","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-43175-thermostat-kit-130f-for-tohatsu-75-90-115-hp-3-cyl-dfi-1-5l-outboards-replaces-oem-833072002","provider":"Good Vibes Marina","version":"1.0","type":"link"}
