Best used as a planned OEM replacement during scheduled maintenance on 30–60 HP Mercury\/Mariner EFI FourStroke outboards at serial 0T409000 and above. The most common customer issue is confusing this complete assembly with other Mercury fuel filter formats — always verify by engine serial number and the parts diagram to confirm the bowl-style filter applies to your specific engine.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324693250084,"sku":"879884T","price":27.67,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/485bd9fb-0d07-42b5-b161-6ed992cdd2dc.png?v=1788201934","url":"https:\/\/marisolmarine.com\/products\/mercury-quicksilver-fuel-filter-assembly-879884t","provider":"Marisol Marine Company","version":"1.0","type":"link"}
