This gasket seals the connection point on the exhaust riser, helping maintain a leak-free joint that keeps exhaust gases and cooling water properly routed away from the engine compartment. It is also included as a component in the Sierra 18-8504 mounting kit, which bundles the gasket together with the mounting bolts needed to install the 18-1899 riser.\u003c\/p\u003e\u003cp\u003eBecause exhaust riser gaskets are a wear item that degrade with heat cycling and vibration, keeping a spare pack of 2 on hand makes it easy to replace the gasket whenever the riser is removed for service or replacement, without having to purchase a full mounting kit if the bolts are still in good condition. This gasket is specific to the 18-1899 riser application; it is not the same gasket used with the 18-1996 manifold, which instead uses the Sierra 18-0183-1 manifold gasket.\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 18-0677-1-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Exhaust Elbow Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2\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 808282381417\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e Sierra 18-1899 Riser (3 inch outlet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded In:\u003c\/strong\u003e Sierra 18-8504 Mounting Kit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eSierra 18-1899 exhaust riser (3 inch outlet)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eNo manufacturer catalog cross-reference numbers are listed for this gasket\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0677-1-9 gasket used for?\u003c\/strong\u003e It is an exhaust riser gasket that seals the connection on the Sierra 18-1899 exhaust riser, which has a 3 inch outlet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket fit the 18-1899 exhaust riser?\u003c\/strong\u003e Yes, the 18-0677-1-9 gasket is designated for use with the Sierra 18-1899 riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets are included in this package?\u003c\/strong\u003e Each package of the 18-0677-1-9 gasket contains 2 gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this gasket also sold as part of a mounting kit?\u003c\/strong\u003e Yes, this gasket is included in the Sierra 18-8504 mounting kit, which also contains the mounting bolts for the 18-1899 riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0677-1-9 gasket package weigh?\u003c\/strong\u003e The package weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0677-1-9 gasket the same one used with the 18-1996 manifold?\u003c\/strong\u003e No, the 18-1996 manifold uses a different gasket, the Sierra 18-0183-1 manifold gasket, which is included in the separate 18-8503 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to buy new mounting bolts when replacing this gasket?\u003c\/strong\u003e Mounting bolts are not included with the 18-0677-1-9 gasket pack on its own; they come bundled only in the Sierra 18-8504 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with this gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0677-1-9 exhaust riser gasket is 808282381417.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I buy just the gasket instead of the full mounting kit?\u003c\/strong\u003e Yes, the 18-0677-1-9 is sold separately as a pack of 2 gaskets, apart from the 18-8504 mounting kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat part does the 18-0677-1-9 gasket connect to on the riser?\u003c\/strong\u003e It seals the mounting joint of the Sierra 18-1899 riser, which is the riser with a 3 inch outlet.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988084437211,"sku":"SIE-18-0677-1-9","price":11.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-0677-9__43049.1739458545.500.750.jpg?v=1785329159","url":"https:\/\/www.goodvibesmarina.com\/products\/exhaust-elbow-riser-gasket-rm0002-for-pleasurecraft-ford-small-block-v8-302-351-inboard-pkg-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
