It is designed to trap contaminants, water, and debris before they reach the carburetor or fuel injection system, helping protect internal engine components from the damage that dirty or wet fuel can cause. This filter is tested and approved for use with ethanol-based fuels, making it suitable for the ethanol-blended gasoline commonly sold at the pump today, and it is built to meet the demands of modern high-performance outboard engines.\u003c\/p\u003e\u003cp\u003eAs a direct OEM replacement, the 18-7781 is designed to install with the same fit and function as the original Yamaha filter it replaces, so no modification is needed during installation. Sierra filters undergo extensive testing in real-world conditions, which is why both professional marine technicians and do-it-yourself boat owners rely on them to keep engines protected. The filter is backed by Sierra's manufacturer warranty for added peace of mind.\u003c\/p\u003e\u003cp\u003eThis is a compact, lightweight component intended for routine fuel system maintenance and scheduled filter replacement on compatible Yamaha outboard engines.\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 18-7781\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Watercraft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEthanol Fuel Compatible:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Fuel Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eYamaha outboard engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha 61N-24563-10-00\u003c\/li\u003e\n\u003cli\u003eYamaha 61N-24563-00-00\u003c\/li\u003e\n\u003cli\u003eYamaha 6R3-24563-00-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7781 fuel filter fit?\u003c\/strong\u003e The Sierra 18-7781 is designed for Yamaha outboard engines and directly replaces the Yamaha filters referenced by part numbers 61N-24563-10-00, 61N-24563-00-00, and 6R3-24563-00-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7781 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-7781 is a genuine Sierra International fuel filter, manufactured by Sierra as a direct replacement for the original Yamaha outboard filter, not a generic third-party part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-7781 replace?\u003c\/strong\u003e It replaces Yamaha 61N-24563-10-00, 61N-24563-00-00, and 6R3-24563-00-00, so any of those OEM numbers can be cross-referenced to this filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7781 fuel filter weigh?\u003c\/strong\u003e The Sierra 18-7781 fuel filter weighs 0.01 pounds, making it a lightweight, compact component for routine fuel system maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this filter work with ethanol-blended gasoline?\u003c\/strong\u003e Yes, the Sierra 18-7781 is tested and approved for use with ethanol-based fuels, so it is compatible with the ethanol-blended gasoline commonly available at fuel pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many filters are included when I order the 18-7781?\u003c\/strong\u003e One Sierra 18-7781 fuel filter is included per unit purchased.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7781 come with a warranty?\u003c\/strong\u003e Yes, the 18-7781 fuel filter is backed by Sierra's limited manufacturer warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between this filter and the original Yamaha filter?\u003c\/strong\u003e Functionally, the Sierra 18-7781 is a direct OEM replacement for the Yamaha 61N-24563-00-00 and related part numbers, engineered to install and perform the same as the original equipment filter it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7781 easy to install as a replacement?\u003c\/strong\u003e As a direct replacement filter, the 18-7781 is designed to install in place of the original Yamaha outboard fuel filter without requiring modification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWho typically uses Sierra fuel filters like the 18-7781?\u003c\/strong\u003e Both professional marine technicians and do-it-yourself boat owners use Sierra filters such as the 18-7781, since they are tested extensively in real-world conditions to protect outboard engines.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988387934427,"sku":"SIE-18-7781","price":10.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7781_lg__95590.1558132042.500.750.jpg?v=1785188203","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7781-fuel-filter-for-yamaha-outboard-9-9-225-hp-replaces-oem-6f5-24563-00-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
