It seals the bypass cover against the engine block or exhaust housing, preventing coolant or exhaust leakage at this joint during operation. Each Sierra 18-2876-9 is sold as a pack of 2 gaskets, so you have a spare on hand or enough to service two mating surfaces in the same job.\u003c\/p\u003e\u003cp\u003eSierra manufactures this gasket to meet or exceed the specification of the original equipment part it replaces, giving you a reliable, properly-fitting seal without sourcing a discontinued OEM number. It is designed as a direct fit for the Johnson and Evinrude outboard bypass cover location that uses OEM part 307133, making it a straightforward drop-in replacement during a bypass cover service, water pump job, or general gasket set refresh.\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 18-2876-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Bypass Cover Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 gaskets per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson and Evinrude outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282163815\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282163815\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson and Evinrude outboard applications\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e307133\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2876-9 bypass cover gasket fit?\u003c\/strong\u003e The Sierra 18-2876-9 is designed for Johnson and Evinrude outboard applications, sealing the bypass cover on these engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a pack of the 18-2876-9?\u003c\/strong\u003e Each pack of the Sierra 18-2876-9 bypass cover gasket contains 2 gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2876-9 a direct replacement for OEM part 307133?\u003c\/strong\u003e Yes, the Sierra 18-2876-9 replaces OEM number 307133 on applicable Johnson and Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2876-9 bypass cover gasket weigh?\u003c\/strong\u003e The Sierra 18-2876-9 bypass cover gasket weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra make this gasket to OEM quality standards?\u003c\/strong\u003e Sierra states that the 18-2876-9 bypass cover gasket meets or exceeds the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2876-9 genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-2876-9 is manufactured by Sierra International as a replacement gasket, not a genuine Johnson\/Evinrude OEM part, though it is designed to match OEM fit and function.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2876-9 bypass cover gasket?\u003c\/strong\u003e The UPC for the Sierra 18-2876-9 bypass cover gasket is 808282163815.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace the bypass cover gasket on my outboard?\u003c\/strong\u003e A bypass cover gasket like the Sierra 18-2876-9 should be replaced whenever the bypass cover is removed for service, such as during a water pump or cooling system job, to ensure a proper seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I buy just one 18-2876-9 gasket instead of a pack of 2?\u003c\/strong\u003e The Sierra 18-2876-9 is sold as a pack of 2 gaskets and is not offered as a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the Sierra 18-2876-9?\u003c\/strong\u003e The Sierra 18-2876-9 is a bypass cover gasket, part of Sierra's Evinrude outboard gasket offerings.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988132442331,"sku":"SIE-18-2876-9","price":3.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2876-9__09387.1722513800.500.750.jpg?v=1785188496","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2876-9-bypass-cover-gasket-for-johnson-evinrude-outboards-replaces-omc-oem-307133-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
