It is sold as a package of 2 gaskets, so both sides or a spare replacement are covered in a single purchase. The gasket is rectangular in shape and grey in color, cut to the flange dimensions of the OEM exhaust elbow gasket it replaces. Installation is a straightforward flat-gasket swap during exhaust elbow removal or servicing, and it is commonly replaced any time the exhaust elbow is pulled for inspection or when an exhaust leak or corrosion is found at the elbow-to-manifold joint. This gasket is designed to meet or exceed the specification of the original equipment part it replaces, giving a reliable seal without sourcing the original manufacturer part. It directly replaces OEM part numbers 27-73814, 27-738141, and 27-807218, and fits the MerCruiser MIE 470 engine application. Always match the gasket to your exhaust elbow's mounting pattern before ordering.\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 18-0954\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Elbow Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 (sold as a pair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Rectangular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Grey\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 030999751980\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-73814, 27-738141, 27-807218\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser MIE 470\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser MIE 470\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e27-73814\u003c\/li\u003e\n\u003cli\u003e27-738141\u003c\/li\u003e\n\u003cli\u003e27-807218\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0954 gasket fit?\u003c\/strong\u003e It fits the MerCruiser MIE 470 engine application, sealing the joint between the exhaust elbow and the exhaust manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a pack?\u003c\/strong\u003e The Sierra 18-0954 is sold as a package of 2 exhaust elbow gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0954 a direct replacement for OEM 27-73814?\u003c\/strong\u003e Yes, the 18-0954 gasket directly replaces OEM part numbers 27-73814, 27-738141, and 27-807218.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the OEM cross-reference numbers for this gasket?\u003c\/strong\u003e OEM cross-reference numbers 27-73814, 27-738141, and 27-807218 all correspond to the Sierra 18-0954 exhaust elbow gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color and shape is the 18-0954 gasket?\u003c\/strong\u003e It is a grey, rectangular gasket sized to match the OEM exhaust elbow flange it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-0954 gasket weigh?\u003c\/strong\u003e The gasket weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace this exhaust elbow gasket?\u003c\/strong\u003e Replace the 18-0954 gasket whenever the exhaust elbow is removed for service or when a leak or corrosion is found at the elbow-to-manifold joint.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-0954 gasket straightforward?\u003c\/strong\u003e Yes, it is a flat gasket that installs during normal removal and reinstallation of the exhaust elbow, requiring no special tools beyond what the elbow service itself calls for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-0954 meet OEM standards?\u003c\/strong\u003e The Sierra 18-0954 gasket is designed to meet or exceed the specification of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-0954?\u003c\/strong\u003e Ordering the Sierra 18-0954 gets you 2 exhaust elbow gaskets, enough for a complete gasket swap or a spare.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0954 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0954 Exhaust Elbow Gasket is 030999751980.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988086534363,"sku":"SIE-18-0954","price":3.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0954_lg__71665.1703251148.500.750.jpg?v=1785188129","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0954-exhaust-elbow-gasket-replaces-mercruiser-27-92720-fits-mercruiser-mie-470","provider":"Good Vibes Marina","version":"1.0","type":"link"}
