It creates a tight, leak-free seal between the exhaust cover plate and the engine housing, helping to prevent exhaust gas and water leakage at this joint during operation. The gasket is round in shape and finished in a multi-colored appearance typical of composite gasket material construction.\u003c\/p\u003e\u003cp\u003eThis is a single-piece gasket sold individually, intended as a direct maintenance replacement part for the exhaust cover plate assembly on applicable Mercury outboard engines. Because gaskets compress and can lose their sealing ability over time or after a cover plate has been removed for service, replacing the gasket with a new Sierra 18-2741 whenever the exhaust cover plate is taken off helps maintain a proper seal and avoid leaks.\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 18-2741\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Cover Plate Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Gaskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Multi-Colored\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282145187\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use on Mercury outboard engines as an exhaust cover plate gasket.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2741 gasket used for?\u003c\/strong\u003e It is an exhaust cover plate gasket that seals the exhaust cover plate on Mercury outboard engines, part number 18-2741.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2741 gasket sold as a single unit or a kit?\u003c\/strong\u003e The Sierra 18-2741 exhaust cover plate gasket ships as a single gasket, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-2741 exhaust cover plate gasket made from?\u003c\/strong\u003e This gasket is made from a glass-composite gasket material and has a multi-colored finish typical of that construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2741 gasket weigh?\u003c\/strong\u003e It weighs 0.16 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-2741 gasket?\u003c\/strong\u003e It is round in shape, matching the exhaust cover plate opening it seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-2741 fit inboard or I\/O engines?\u003c\/strong\u003e The 18-2741 gasket is categorized as a Mercury outboard gasket for the exhaust cover plate application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the exhaust cover plate gasket be replaced?\u003c\/strong\u003e The 18-2741 gasket should be replaced any time the exhaust cover plate is removed for service, since a compressed or disturbed gasket can no longer seal reliably.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-2741 a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e 18-2741 is the Sierra brand part number for this exhaust cover plate gasket, manufactured and sold under the Sierra brand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2741 gasket?\u003c\/strong\u003e The UPC for this exhaust cover plate gasket is 808282145187.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2741 gasket leak if reused after removal?\u003c\/strong\u003e Gaskets like the 18-2741 are designed for one-time use; reusing a compressed exhaust cover plate gasket increases the risk of exhaust or water leakage, so a new one is recommended at each cover plate removal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988109635803,"sku":"SIE-18-2741","price":13.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-2741_lg__41839.1558123745.500.750.jpg?v=1785189077","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2741-exhaust-cover-plate-gasket-replaces-mercury-27-430047-mercury-outboard-gaskets","provider":"Good Vibes Marina","version":"1.0","type":"link"}
