It crosses directly to Sierra 18-7906-2 and to five successive Yamaha 69J-series OEM filter revisions, as well as three Mercury OEM numbers. Built with high-efficiency cellulose filter media, an epoxy-coated canister, reinforced body construction, heavy-duty end-cap seals, and an anti-drain-back valve, it meets or exceeds original equipment filtration requirements.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFiltration: 20 micron\u003c\/li\u003e\n\u003cli\u003eFilter type: Full-flow spin-on\u003c\/li\u003e\n\u003cli\u003eFilter media: High-efficiency cellulose\u003c\/li\u003e\n\u003cli\u003eAnti-drain-back valve: Yes\u003c\/li\u003e\n\u003cli\u003eCanister: Epoxy-coated steel for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBody: Reinforced construction\u003c\/li\u003e\n\u003cli\u003eEnd-cap seals: Heavy-duty\u003c\/li\u003e\n\u003cli\u003eManufactured in an ISO\/TS 16949 certified facility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMercury FourStroke outboards specifying filter 35-8226267, 35-822626Q15, or 35-822626T7\u003c\/li\u003e\n\u003cli\u003eYamaha 4-stroke outboards specifying Yamaha 69J-13440-series filters (models 00 through 04)\u003c\/li\u003e\n\u003cli\u003eApplications cross-referencing Sierra 18-7906-2\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Mercury and Yamaha use several similar-looking filters across their 4-stroke outboard lineups.

This is one of the most common outboard oil filter applications — the five Yamaha 69J-13440 part numbers (revisions 00 through 04) all represent successive OEM updates to the same filter, and this Seachoice unit replaces all of them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e The most frequent ordering error is filter confusion across similar-looking outboard filters — Mercury and Yamaha both use multiple spin-on filter sizes across their 4-stroke lineups. Always confirm the existing filter’s part number rather than ordering by appearance. The Sierra 18-7906-2 cross-reference is the fastest way to confirm fit if a customer is unsure which Seachoice number they need.\u003c\/p\u003e\n\n\u003c\/section\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199648301092,"sku":"50-21011","price":17.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/50-21017_Main_439c46d4-9f71-45c8-ad25-93921d8f1516.jpg?v=1785611137","url":"https:\/\/marisolmarine.com\/products\/seachoice-50-21011-full-flow-oil-filter-20-micron","provider":"Marisol Marine Company","version":"1.0","type":"link"}
