It is built around an epoxy-coated, heavy-wall steel canister that resists corrosion in the marine environment, paired with high-efficiency filter media designed to meet or exceed OE filtration standards. An anti-drain-back valve keeps oil in the filter between starts, protecting critical engine components from dry-start wear and helping maintain steady oil pressure from the moment the engine fires.\u003c\/p\u003e\u003cp\u003eThis filter is sized for Mercury Verado L6 outboards rated 225, 250, and 275 horsepower (2005-2011) and 300 horsepower (2007-2011), each of which uses a 7.0L \/ 7.40 quart crankcase filled with 25W-50 synthetic blend FC-W oil. It uses a 24mm x 1.5 thread and directly replaces Mercury OEM filter 35-877769K01, so it installs using the same mounting thread and filter footprint as the original part. The canister measures 5 x 3.25 x 3.25 inches and weighs 0.81 pounds. Whether performing a scheduled oil change or a full service, this filter is a straightforward, direct-fit replacement for the covered Verado L6 outboard models.\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 18-7918\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 35-877769K01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Mercury Verado L6 225 HP (2005-2011), 250 HP (2005-2011), 275 HP (2005-2011), 300 HP (2007-2011)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrankcase Capacity:\u003c\/strong\u003e 7.0L \/ 7.40 Qt.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Oil:\u003c\/strong\u003e 25W-50 Synthetic Blend FC-W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 24mm x 1.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 5 x 3.25 x 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.81 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Feature:\u003c\/strong\u003e Anti-drain-back valve\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Verado L6 225 HP, 2005-2011\u003c\/li\u003e\n\u003cli\u003eMercury Verado L6 250 HP, 2005-2011\u003c\/li\u003e\n\u003cli\u003eMercury Verado L6 275 HP, 2005-2011\u003c\/li\u003e\n\u003cli\u003eMercury Verado L6 300 HP, 2007-2011\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e35-877769K01\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7918 oil filter fit?\u003c\/strong\u003e The Sierra 18-7918 fits Mercury Verado L6 in-line six-cylinder outboards rated 225 HP, 250 HP, and 275 HP (2005-2011), as well as the 300 HP Verado L6 (2007-2011).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-7918 replace?\u003c\/strong\u003e Sierra 18-7918 directly replaces Mercury OEM oil filter 35-877769K01, using the same 24mm x 1.5 thread and filter footprint.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this filter use?\u003c\/strong\u003e The 18-7918 uses a 24mm x 1.5 thread, matching the mounting thread of the Mercury Verado L6 outboards it is designed for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much oil does a Verado L6 crankcase hold when using this filter?\u003c\/strong\u003e The covered Verado L6 outboards (225, 250, 275, and 300 HP) hold 7.0L \/ 7.40 quarts of crankcase oil when serviced with the 18-7918 filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of oil should be used with the 18-7918 filter?\u003c\/strong\u003e Mercury Verado L6 outboards using the 18-7918 filter call for 25W-50 synthetic blend FC-W oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-7918 filter made of?\u003c\/strong\u003e It is built with an epoxy-coated, heavy-wall steel canister for corrosion resistance in the marine environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7918 have an anti-drain-back valve?\u003c\/strong\u003e Yes, an anti-drain-back valve is built into the 18-7918 to retain oil in the filter between engine starts, reducing dry-start wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-7918 oil filter?\u003c\/strong\u003e The filter canister measures 5 x 3.25 x 3.25 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7918 oil filter weigh?\u003c\/strong\u003e The Sierra 18-7918 weighs 0.81 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7918 a genuine Mercury part or an aftermarket replacement?\u003c\/strong\u003e The 18-7918 is a Sierra-branded replacement filter engineered to meet or exceed OE filtration performance while cross-referencing to Mercury OEM part 35-877769K01.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-7918 be used on any Mercury outboard?\u003c\/strong\u003e No, the 18-7918 is sized specifically for Mercury Verado L6 outboards rated 225, 250, 275 HP (2005-2011) and 300 HP (2007-2011);
