Built with a synthetic\/glass fiber filter media, it is manufactured to meet or exceed OEM specifications and is field-tested and approved for reliable filtration performance. The filter includes anti-drainback valves where required, helping keep oil in the filter housing between engine starts so lubrication reaches critical engine components faster at startup. As a performance-grade replacement filter, the Sierra 18-7902 is designed to fit specific Yamaha outboard model years and displacements, making it a straightforward drop-in replacement during scheduled oil changes. It carries a 90 day manufacturer warranty. Always confirm your outboard model and year against the fitment list before ordering to ensure correct compatibility.\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 18-7902\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Synthetic\/Glass Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Grade:\u003c\/strong\u003e Performance Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282244873\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Warranty:\u003c\/strong\u003e 90 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 3FV-13440-10-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha F25, 1998 - 1999, 1.7 L \/ 1.8 Qt., 10W-30 FC-W\u003c\/li\u003e\n\u003cli\u003eYamaha F40, 1999 - 2000, 2.0 L \/ 2.1 Qt., 10W-30 FC-W\u003c\/li\u003e\n\u003cli\u003eYamaha T50, 1996 - 1999, 2.0 L \/ 2.1 Qt., 10W-30 FC-W\u003c\/li\u003e\n\u003cli\u003eYamaha F50, 1995 - 1999, 2.0 L \/ 2.1 Qt., 10W-30 FC-W\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e3FV-13440-10-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7902 oil filter fit?\u003c\/strong\u003e The Sierra 18-7902 fits Yamaha F25 outboards from 1998 to 1999, F40 outboards from 1999 to 2000, T50 outboards from 1996 to 1999, and F50 outboards from 1995 to 1999, all using 10W-30 FC-W oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7902 filter an OEM equivalent?\u003c\/strong\u003e Yes, the Sierra 18-7902 is manufactured to meet or exceed OEM specifications and directly replaces the Yamaha OEM filter numbered 3FV-13440-10-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-7902 replace?\u003c\/strong\u003e It replaces Yamaha OEM oil filter 3FV-13440-10-00 on the applicable Yamaha 4-stroke outboard models and years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7902 oil filter weigh?\u003c\/strong\u003e The Sierra 18-7902 oil filter weighs 0.48 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-7902 filter made of?\u003c\/strong\u003e The filter media on the Sierra 18-7902 is synthetic\/glass fiber, designed for consistent filtration performance in a marine 4-stroke oil system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7902 have an anti-drainback valve?\u003c\/strong\u003e Yes, the 18-7902 includes anti-drainback valves where required, which help retain oil in the filter between startups.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7902 come with a warranty?\u003c\/strong\u003e The Sierra 18-7902 oil filter is backed by a 90 day manufacturer warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many filters come in one order of 18-7902?\u003c\/strong\u003e Each order of the Sierra 18-7902 includes one oil filter (unit count of 1).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7902 a genuine Yamaha part or aftermarket?\u003c\/strong\u003e The 18-7902 is a Sierra aftermarket performance part built to meet or exceed Yamaha OEM specifications, not a Yamaha-branded original part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat oil weight should be used with the Yamaha outboards that take the 18-7902?\u003c\/strong\u003e The Yamaha outboard applications for the 18-7902 (F25, F40, T50, F50) call for 10W-30 FC-W rated oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7902 oil filter?\u003c\/strong\u003e The UPC for the Sierra 18-7902 oil filter is 808282244873.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988389834971,"sku":"SIE-18-7902","price":9.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7902_lg__50670.1558132192.500.750.jpg?v=1785188308","url":"https:\/\/www.goodvibesmarina.com\/products\/oil-filter-for-yamaha-4-stroke-outboards-replaces-3fv-13440-00-00-anti-drain-back-valve-sierra-18-7902","provider":"Good Vibes Marina","version":"1.0","type":"link"}
