It seals the cover plate against leaks at the mating surface, restoring a tight fit after the original gasket has hardened, torn, or compressed with age. Sierra manufactures this gasket to meet or exceed the specifications of the original equipment part it replaces, giving installers a reliable, drop-in alternative to the OEM component without hunting down a discontinued factory part.\u003c\/p\u003e\u003cp\u003eBecause it is a low-cost wear item, the Cover Plate Gasket is commonly replaced any time the cover plate is removed for service, since reusing an old gasket risks a leak. The pack-of-two format makes it practical to keep a spare on hand or to service a pair of engines or covers in a single order.\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 18-2880-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Cover Plate Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 2 gaskets per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson and Evinrude outboard engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282163853\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 304023\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Johnson and Evinrude outboard applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e304023\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2880-9 Cover Plate Gasket fit?\u003c\/strong\u003e This gasket is designed for Johnson and Evinrude outboard applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package?\u003c\/strong\u003e The 18-2880-9 is sold as a package of two cover plate gaskets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-2880-9 replace?\u003c\/strong\u003e It replaces Johnson\/Evinrude part number 304023.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this gasket weigh?\u003c\/strong\u003e The Sierra 18-2880-9 Cover Plate Gasket weighs 0.02 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the cover plate gasket?\u003c\/strong\u003e It is a round gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2880-9 an OEM part or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket gasket manufactured to meet or exceed the specifications of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace this gasket?\u003c\/strong\u003e Any time the cover plate on a Johnson or Evinrude outboard is removed for service, since reusing a hardened or torn gasket risks a leak; the 18-2880-9 provides a fresh replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with part number 18-2880-9?\u003c\/strong\u003e Two Cover Plate Gaskets are included in each package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra make this gasket for other outboard brands?\u003c\/strong\u003e The 18-2880-9 is designated for Johnson and Evinrude applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2880-9 gasket?\u003c\/strong\u003e The UPC is 808282163853.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988132737243,"sku":"SIE-18-2880-9","price":6.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2880-9__62332.1737843459.500.750.jpg?v=1785188168","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2880-9-cover-plate-gasket-replaces-oem-304023-for-johnson-evinrude-v-4-outboards-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
