Its heavy-wall steel canister is epoxy coated for corrosion resistance, an important feature for a component that lives in a marine engine bay and is regularly exposed to moisture and salt air. Inside, the high-efficiency filter media meets or exceeds OE filtration standards, helping keep engine oil free of contaminants that accelerate wear on internal components.\u003c\/p\u003e\u003cp\u003eThis filter uses a 22mm x 15 thread spec and is designed as a direct fit for specific Mercury 4-stroke outboard applications, so it threads on and seals the way the original equipment filter did. It is intended for routine oil-change service and is compatible with 10W-30 FC-W oil across its listed applications. Whether you are performing scheduled maintenance or replacing a worn filter, the 18-7758 is built to hold up to the demands of the marine environment while protecting your engine's oil supply.\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 18-7758\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Oil Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Epoxy Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 22mm x 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4 x 4 x 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.89 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 35-877761K01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Oil Viscosity:\u003c\/strong\u003e 10W-30 FC-W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e One (1) Oil Filter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 75HP EFI (1B366822 \u0026amp; Above), 2006-2011\u003c\/li\u003e\n\u003cli\u003eMercury 90HP EFI (1B366822 \u0026amp; Above), 2006-2011\u003c\/li\u003e\n\u003cli\u003eMercury 115HP EFI (1B366822 \u0026amp; Above), 2006-2011\u003c\/li\u003e\n\u003cli\u003eMercury 150HP (4-Stroke), 2011-2015\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e35-877761K01\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7758 oil filter fit?\u003c\/strong\u003e The 18-7758 fits Mercury 75HP, 90HP, and 115HP EFI 4-stroke outboards (1B366822 and above), 2006-2011, as well as the Mercury 150HP 4-stroke outboard, 2011-2015.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7758 a direct replacement for the Mercury OEM filter?\u003c\/strong\u003e Yes, it directly replaces Mercury OEM part number 35-877761K01.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this oil filter use?\u003c\/strong\u003e The 18-7758 has a 22mm x 15 thread spec, matching the original Mercury filter it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-7758 filter canister made of?\u003c\/strong\u003e It is made of steel with an epoxy coating for corrosion resistance, plus a heavy-wall canister design for further protection against corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-7758 oil filter weigh?\u003c\/strong\u003e This oil filter weighs 0.89 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-7758 oil filter?\u003c\/strong\u003e The filter measures 4 x 4 x 3 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat oil should be used with the 18-7758 filter?\u003c\/strong\u003e Across its listed Mercury outboard applications, 10W-30 FC-W is the recommended oil for use with the 18-7758.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7758 filter meet OE filtration standards?\u003c\/strong\u003e Its filter media meets or exceeds the original equipment manufacturer's filtration performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order part number 18-7758?\u003c\/strong\u003e One oil filter is included per order of the Sierra 18-7758.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7758 fit a Mercury 75HP carbureted outboard?\u003c\/strong\u003e No, the 18-7758 is specified for the 75HP EFI application (1B366822 and above), 2006-2011, not the carbureted version.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-7758 is a genuine Sierra-branded oil filter, sold under Sierra's own part number and warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7758 filter come with a warranty?\u003c\/strong\u003e Yes, the Sierra 18-7758 is backed by Sierra's manufacturer warranty.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988387442907,"sku":"SIE-18-7758","price":9.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/Untitled-1__98626.1753840720.500.750.jpg?v=1785188221","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-oil-filter-for-mercury-75-90-115-150-hp-4-stroke-outboards-replaces-35-877761k01-sierra-18-7758","provider":"Good Vibes Marina","version":"1.0","type":"link"}
