It is made of graphite-infused stainless steel for superior compressibility, letting it conform to mating surfaces and hold a reliable seal under the heat and vibration of engine operation. Each gasket is sold in a pack of two so both end caps on an engine can be replaced together during a manifold service or gasket refresh. This gasket is a direct replacement for OEM part 27-73814, giving MerCruiser owners a straightforward way to source the correct seal without hunting down the original part. It fits MerCruiser MCM\/MIE 120 (2.5L), 140 (3.0L), and 165 inline 6-cylinder engines, as well as MCM\/MIE 470, 898, 228, and 260 engines. Backed by Sierra's industry-leading warranty, it is a precision-made component intended for straightforward removal-and-replace installation during routine exhaust manifold maintenance.\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 18-0928-1-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e Pack of 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Graphite-infused stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 7.01 x 6.97 x 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282369187\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercruiser exhaust manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 120 (2.5L)\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 140 (3.0L)\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 165 (inline 6-cylinder)\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 470\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 898\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 228\u003c\/li\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 260\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e27-73814\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0928-1-9 gasket fit?\u003c\/strong\u003e This gasket fits MerCruiser MCM\/MIE 120 (2.5L), 140 (3.0L), and 165 inline 6-cylinder engines, along with MCM\/MIE 470, 898, 228, and 260 engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-0928-1-9 replace?\u003c\/strong\u003e It is a direct replacement for OEM part 27-73814, the manifold end cap gasket used on the fitted MerCruiser engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package?\u003c\/strong\u003e Sierra 18-0928-1-9 is sold in a pack of two gaskets, enough to service both end caps on a single engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra manifold end cap gasket made from?\u003c\/strong\u003e The gasket is made of graphite-infused stainless steel, chosen for its compressibility and ability to hold a seal under engine heat and vibration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this gasket weigh?\u003c\/strong\u003e The Sierra 18-0928-1-9 manifold end cap gasket weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the gasket?\u003c\/strong\u003e Each individual gasket measures 0.39 x 0.39 x 0.39 inches, and the retail package measures 7.01 x 6.97 x 0.31 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e 18-0928-1-9 is a genuine Sierra part, backed by Sierra's industry-leading warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is this gasket used on the engine?\u003c\/strong\u003e It seals the joint between the exhaust manifold and the manifold end cap on the fitted MerCruiser engines, preventing exhaust and coolant leaks at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install this gasket myself?\u003c\/strong\u003e Yes, the Sierra 18-0928-1-9 manifold end cap gasket is designed as a direct removal-and-replace part for routine exhaust manifold service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this part?\u003c\/strong\u003e Ordering 18-0928-1-9 gets you two manifold end cap gaskets, matching the OEM 27-73814 specification.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988086501595,"sku":"SIE-18-0928-1-9","price":17.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0928_lg_1__91574.1670333906.500.750.jpg?v=1785188871","url":"https:\/\/www.goodvibesmarina.com\/products\/mercruiser-manifold-end-cap-gasket-27-73814-2-pack-fits-mcm-mie-120-140-165-470-898-228-260","provider":"Good Vibes Marina","version":"1.0","type":"link"}
