It is built from aluminum construction and finished in red, matching the original equipment appearance for a clean, factory-correct look on reinstallation. This is a small but critical sealing component: a worn or reused drain screw gasket is a common source of slow oil weeps around the drain plug, so replacing it whenever the drain screw is removed for a service interval helps maintain a proper seal and keeps the powerhead free of leaks.\u003c\/p\u003e\u003cp\u003eSierra manufactures the 18-0826 to match the Yamaha OEM specification 90430-14115-00-00, so it installs the same way as the original gasket with no modification required. It ships as a single gasket (package quantity of 1) sized to fit the drain screw location on covered Yamaha outboard engines. Given its light weight and compact size, it is typically kept on hand as a routine maintenance part alongside other gaskets replaced during oil changes or lower-unit service.\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 18-0826\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Drain Screw Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 1 inch x 1 inch x 0.3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999874757\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 90430-14115-00-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Yamaha outboard motors using drain screw gasket 90430-14115-00-00.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e90430-14115-00-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0826 fit?\u003c\/strong\u003e The Sierra 18-0826 drain screw gasket is designed for Yamaha outboard motors and is a direct match for OEM part 90430-14115-00-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0826 the same as the Yamaha OEM gasket?\u003c\/strong\u003e Yes, the Sierra 18-0826 is manufactured to the same specification as Yamaha OEM number 90430-14115-00-00 and installs the same way.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the drain screw gasket made from?\u003c\/strong\u003e It is made from aluminum, finished in red to match the original Yamaha appearance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package?\u003c\/strong\u003e The Sierra 18-0826 ships as a single gasket, with a package quantity of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-0826?\u003c\/strong\u003e Packaged dimensions are 1 inch by 1 inch by 0.3 inch, reflecting the small size typical of a drain screw gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0826 weigh?\u003c\/strong\u003e The Sierra 18-0826 weighs 0.01 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace this gasket?\u003c\/strong\u003e This drain screw gasket should be replaced any time the drain screw is removed, such as during an oil change or lower-unit service, since a reused gasket is a common source of slow leaks around the drain plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0826 an aftermarket or genuine part?\u003c\/strong\u003e The 18-0826 is a Sierra-manufactured gasket built to match the Yamaha OEM specification 90430-14115-00-00, rather than a Yamaha-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engine type is this gasket used with?\u003c\/strong\u003e The Sierra 18-0826 drain screw gasket is used on 4 stroke gasoline outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the color of the gasket matter for fit?\u003c\/strong\u003e No, the red finish on the Sierra 18-0826 is a cosmetic match to the original equipment and does not affect the seal or fit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988085879003,"sku":"SIE-18-0826","price":1.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0826_lg__06664.1711979440.500.750.jpg?v=1785188749","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0826-exhaust-cover-gasket-for-yamaha-outboards-replaces-oem-688-41112-a0-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
