It is built for Yamaha F50-F115 outboards manufactured after April 2006, where it filters contaminants and debris from the fuel supply before they reach the carburetor or fuel injection system, helping protect internal engine components and maintain consistent fuel delivery. The filter element features a metal outer construction for durability in a marine engine compartment environment. Because Yamaha used more than one filter housing design across this engine range, this filter is matched specifically to housings marked \"6D8\" -- installing it in a housing with a different marking will not provide a proper fit or seal, so confirm your housing marking before ordering. This is a genuine Sierra part manufactured to match Yamaha OEM specifications, sold as a single fuel filter unit. Replacing the fuel filter at the manufacturer-recommended interval helps prevent fuel flow restrictions, hard starting, and rough running caused by a clogged or degraded filter element.\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 18-79809\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Material:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Housing Marking:\u003c\/strong\u003e 6D8 only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282277413\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha F50-F115 outboards, after April 2006\u003c\/li\u003e\n\u003cli\u003eFor filter housings marked \"6D8\" only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e6D8-WS24A-00-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-79809 fuel filter fit?\u003c\/strong\u003e The Sierra 18-79809 fits Yamaha F50-F115 outboards manufactured after April 2006.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this filter fit any Yamaha outboard in the F50-F115 range?\u003c\/strong\u003e Only if the engine's filter housing is marked \"6D8\" -- the Sierra 18-79809 is designed exclusively for that housing marking, and a different marking indicates a different filter is needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-79809 replace?\u003c\/strong\u003e It replaces Yamaha OEM number 6D8-WS24A-00-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my filter housing is marked 6D8?\u003c\/strong\u003e The housing marking is stamped or printed directly on the fuel filter housing itself; check that marking against \"6D8\" before ordering the Sierra 18-79809 to ensure correct fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the fuel filter's outer material?\u003c\/strong\u003e The Sierra 18-79809 has a metal outer construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-79809 fuel filter weigh?\u003c\/strong\u003e It weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many filters come in one Sierra 18-79809 unit?\u003c\/strong\u003e One unit includes a single fuel filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-79809 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-79809 is manufactured by Sierra to match Yamaha OEM fitment and specifications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow often should I replace this fuel filter?\u003c\/strong\u003e Replace the Sierra 18-79809 at your Yamaha outboard's manufacturer-recommended fuel filter service interval to avoid fuel flow restriction from a clogged element.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a different Sierra filter for other Yamaha housing markings?\u003c\/strong\u003e Yes -- housings marked differently than \"6D8\" require a different Sierra fuel filter part number, since the 18-79809 is matched specifically to the 6D8 housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms indicate the fuel filter needs replacement?\u003c\/strong\u003e Hard starting, rough running, or reduced fuel flow on a Yamaha F50-F115 outboard after April 2006 can indicate the 18-79809 fuel filter needs replacing.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988427419867,"sku":"SIE-18-79809","price":17.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__28496.1753840693.500.750.jpg?v=1785188225","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-79809-fuel-filter-for-yamaha-f50-f115-outboards-after-april-2006-replaces-6d8-ws24a-00-00-6d8-housing-only","provider":"Good Vibes Marina","version":"1.0","type":"link"}
