It seals the joint between the exhaust manifold and the powerhead, containing exhaust gases and cooling water so the manifold runs leak-free and the cooling circuit stays sealed under engine heat and vibration. This gasket is a direct cross to Yamaha OEM part 6E5-41112-A1-00, giving you a genuine-fit replacement without having to source through the engine manufacturer. Two gaskets are used per engine application, so plan to order accordingly when doing a manifold service or full gasket set replacement. As with any exhaust manifold gasket, install it dry (unless the engine manual specifies otherwise), torque the manifold fasteners to the engine manufacturer's spec in the proper sequence, and replace the gasket any time the manifold is removed rather than reusing the old one. The round gasket ships as a single component, ready to install, and is sized and shaped to match the mounting pattern of the Yamaha manifold it services.\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 18-0823\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Manifold Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Yamaha Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Required Per Engine:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282257446\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 6E5-41112-A1-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha outboard engines using OEM exhaust manifold gasket 6E5-41112-A1-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e6E5-41112-A1-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0823 gasket fit?\u003c\/strong\u003e The Sierra 18-0823 is an exhaust manifold gasket built for Yamaha outboard engines, cross-referencing to Yamaha OEM part 6E5-41112-A1-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-0823 the same as Yamaha part 6E5-41112-A1-00?\u003c\/strong\u003e Yes, Sierra 18-0823 is the direct cross-reference replacement for Yamaha OEM exhaust manifold gasket 6E5-41112-A1-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets do I need for one engine?\u003c\/strong\u003e Two of the Sierra 18-0823 exhaust manifold gaskets are required per engine application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is this gasket?\u003c\/strong\u003e The 18-0823 exhaust manifold gasket is round in shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0823 gasket weigh?\u003c\/strong\u003e Sierra part 18-0823 weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this part?\u003c\/strong\u003e Ordering Sierra 18-0823 gets you one exhaust manifold gasket; since two are required per engine, order two units for a complete job.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-0823 is a Sierra-branded exhaust manifold gasket manufactured as a cross-reference replacement for the Yamaha OEM gasket, not an OEM Yamaha part itself.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould I reuse the old exhaust manifold gasket instead of buying 18-0823?\u003c\/strong\u003e No, exhaust manifold gaskets like the Sierra 18-0823 should be replaced any time the manifold is removed rather than reused, to ensure a proper seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0823 gasket need sealant during installation?\u003c\/strong\u003e Sierra 18-0823 is a standard exhaust manifold gasket; follow your engine manufacturer's torque sequence and sealant guidance when installing it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with Sierra 18-0823?\u003c\/strong\u003e The UPC for the Sierra 18-0823 exhaust manifold gasket is 808282257446.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use 18-0823 on a non-Yamaha outboard?\u003c\/strong\u003e Sierra 18-0823 is designed for Yamaha outboard applications matching OEM part 6E5-41112-A1-00; fitment outside that application is not confirmed.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988085747931,"sku":"SIE-18-0823","price":7.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0823_lg__34400.1558120846.500.750.jpg?v=1785188556","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0823-exhaust-manifold-gasket-for-yamaha-outboard-replaces-oem-6e5-13645-a1-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
