It is sold as a pack of 2, giving you a spare on hand or enough to service two engines in one order. The gasket is designed to restore a tight, leak-free seal at the exhaust housing joint, preventing exhaust gas and water leakage that can occur once the original gasket hardens or compresses with age and heat cycling. As a direct-fit replacement, it is built to the original dimensions and mounting pattern so it installs in the same location as the factory gasket without modification. Sierra manufactures this gasket to meet or exceed the specifications of the original equipment part it replaces, making it a straightforward choice when servicing the exhaust housing during a tune-up, gasket set replacement, or troubleshooting an exhaust leak. It cross-references directly to Johnson\/Evinrude OEM part numbers 313065 and 306205, so it is easy to confirm as the correct part before ordering. This gasket is intended specifically for the 5, 5.5, and 6 HP Johnson\/Evinrude outboard family and is not a universal fit for other horsepower ranges.\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 18-2901-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Housing Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e Pack of 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Johnson\/Evinrude (OMC\/BRP) Outboard, 5, 5.5, 6 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 313065, 306205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282164041\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude (OMC\/BRP) Outboard, 5, 5.5, 6 HP\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e313065\u003c\/li\u003e\n\u003cli\u003e306205\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-2901-9 exhaust housing gasket fit?\u003c\/strong\u003e The Sierra 18-2901-9 is designed for Johnson and Evinrude (OMC\/BRP) outboard motors rated 5, 5.5, and 6 HP.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one order of 18-2901-9?\u003c\/strong\u003e Each order of the Sierra 18-2901-9 exhaust housing gasket includes a pack of 2 gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does this gasket replace?\u003c\/strong\u003e Sierra 18-2901-9 replaces Johnson\/Evinrude OEM part numbers 313065 and 306205.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2901-9 gasket genuine OEM or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket replacement gasket, manufactured to meet or exceed the specifications of the original Johnson\/Evinrude equipment part it replaces (313065, 306205).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2901-9 exhaust housing gasket weigh?\u003c\/strong\u003e The Sierra 18-2901-9 exhaust housing gasket weighs 0.09 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the exhaust housing gasket located on the outboard?\u003c\/strong\u003e The 18-2901-9 seals the exhaust housing joint on 5, 5.5, and 6 HP Johnson\/Evinrude outboards to prevent exhaust and water leakage at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use 18-2901-9 on a larger horsepower Johnson\/Evinrude outboard?\u003c\/strong\u003e No, the Sierra 18-2901-9 exhaust housing gasket is specified for the 5, 5.5, and 6 HP Johnson\/Evinrude engine family and is not listed as a fit for other horsepower ranges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any special tools to install this gasket?\u003c\/strong\u003e Installation involves removing the exhaust housing to access the old gasket and fitting the new Sierra 18-2901-9 gasket in its place; no specialty tools beyond standard outboard service tools are indicated for this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2901-9 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-2901-9 exhaust housing gasket, pack of 2, is 808282164041.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace the exhaust housing gasket?\u003c\/strong\u003e Exhaust housing gaskets like the Sierra 18-2901-9 can harden or compress over time, leading to exhaust or water leaks at the housing joint, which is when replacement with a fresh gasket set is needed.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988132835547,"sku":"SIE-18-2901-9","price":17.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2901-9__53623.1722383205.500.750.jpg?v=1785188169","url":"https:\/\/www.goodvibesmarina.com\/products\/exhaust-housing-gasket-for-johnson-evinrude-5-5-5-6-hp-outboards-replaces-omc-306205-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
