Water shutters regulate raw water flow through the exhaust and cooling passages, helping maintain proper engine operating temperature and preventing exhaust water from backing up into the engine when it is not running. This part is built to meet or exceed the specifications of the original equipment it replaces, making it a direct, reliable substitute for worn or failed shutters.\u003c\/p\u003e\u003cp\u003eMeasuring 3.175 inches in length and 2.5 inches in width, the 18-2733 is manufactured under the Sierra brand for durability in continuous exposure to raw water and marine exhaust conditions. It replaces OEM numbers 92802 and 99370A2, so it fits applications originally equipped with either of those parts. Because it ships as a package of 2 and is priced per package, buyers replacing shutters in pairs can source both from a single part number.\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 18-2733\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 3.175 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 (priced per package)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282124670\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFits applications originally equipped with OEM water shutter 92802 or 99370A2\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e92802\u003c\/li\u003e\n\u003cli\u003e99370A2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2733 water shutter do?\u003c\/strong\u003e It regulates raw water flow through a stern drive's cooling and exhaust passages, helping the engine reach and hold proper operating temperature and limiting water backing up into the exhaust when the engine is off.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many shutters come in a package of the 18-2733?\u003c\/strong\u003e The 18-2733 is sold as a package of 2 and is priced per package, not per individual shutter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-2733 replace?\u003c\/strong\u003e It replaces OEM numbers 92802 and 99370A2, so either of those part numbers can be cross-referenced to the 18-2733.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2733 water shutter?\u003c\/strong\u003e It measures 3.175 inches in length and 2.5 inches in width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2733 weigh?\u003c\/strong\u003e Each package weighs 0.14 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2733 an OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-2733 is a Sierra-brand replacement part engineered to meet or exceed the specifications of the original equipment water shutter it replaces (92802 or 99370A2).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2733 fit any boat with a water shutter?\u003c\/strong\u003e It is a direct replacement only for applications that originally used OEM water shutter 92802 or 99370A2; confirm your original part number before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the Sierra 18-2733?\u003c\/strong\u003e One package containing 2 water shutters (Sierra part number 18-2733) is included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2733 water shutter?\u003c\/strong\u003e The UPC is 808282124670.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I order a single water shutter instead of a pair?\u003c\/strong\u003e No, the Sierra 18-2733 is packaged and priced as a set of 2 shutters.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988109603035,"sku":"SIE-18-2733","price":26.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2733_lg__12501.1558123391.500.750.jpg?v=1785188495","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2733-water-shutter-for-mercruiser-stern-drive-replaces-92802-pkg-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
