It uses a heavy-wall steel canister with an epoxy coating for corrosion resistance, and it is fitted with an anti-drain-back valve that keeps oil in the filter between engine starts so lubrication reaches critical components immediately on startup instead of after a delay. Inside, a high-efficiency filter media meets or exceeds the filtration performance of the original equipment filter it replaces.\u003c\/p\u003e\u003cp\u003eThis filter is engineered to meet the demands of high-horsepower marine engines and is manufactured to meet or exceed the specifications of the original equipment part. It threads on with a 3\/4 inch x 16 NPT thread and measures 3 x 2.9 x 2.8 inches with a 0.75 inch outside diameter. Use it with a 10W40 synthetic blend FC-W rated engine oil.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-7915-1 replace?\u003c\/strong\u003e The Sierra 18-7915-1 oil filter replaces OEM part numbers 5031411 and 778885, so either number can be used to confirm this is the correct filter for your engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Evinrude outboards fit the 18-7915-1 filter?\u003c\/strong\u003e This filter fits Evinrude 25 HP (2000-2001 and 2004-2007), 30 HP (2000-2001 and 2004-2007), 40 HP (1999-2006), 50 HP (1999-2006), 60 HP (2002-2006), and 70 HP (2001-2006) outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this filter have an anti-drain-back valve?\u003c\/strong\u003e Yes, the 18-7915-1 includes an anti-drain-back valve, which keeps oil inside the filter between starts so the engine gets lubrication immediately on startup rather than running dry for a few seconds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Sierra 18-7915-1 use?\u003c\/strong\u003e It uses a 3\/4 inch x 16 NPT thread, and the filter has a 0.75 inch outside diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 18-7915-1 filter made of?\u003c\/strong\u003e It is built with a heavy-wall steel canister that is epoxy coated for corrosion resistance in the marine environment, a step up from typical automotive filter housings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat oil should be used with the 18-7915-1 filter?\u003c\/strong\u003e Sierra specifies a 10W40 synthetic blend FC-W rated engine oil for use with the 18-7915-1 on the Evinrude outboards it fits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much oil does my Evinrude outboard hold when using this filter?\u003c\/strong\u003e Oil capacity depends on the engine: 25-30 HP models take 3.2 L \/ 3.4 Qt, 40-50 HP models take 2.4 L \/ 2.5 Qt, and 60-70 HP models take 4.5 L \/ 4.8 Qt, all using 10W40 synthetic blend FC-W oil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and weight of the Sierra 18-7915-1?\u003c\/strong\u003e The filter measures 3 x 2.9 x 2.8 inches and weighs 0.47 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7915-1 a genuine part or aftermarket?\u003c\/strong\u003e The 18-7915-1 is a Sierra branded filter manufactured to meet or exceed the filtration performance of the original equipment part it replaces, backed by Sierra's warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-7915-1?\u003c\/strong\u003e Each order includes one 18-7915-1 oil filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7915-1 the same filter used on other Evinrude horsepower ratings?\u003c\/strong\u003e No. Evinrude 15 HP (1995-2001) and 70 HP (1998-2000) models use the 18-7916 filter instead, a different Sierra part number, so it is important to match the filter to your engine's HP and model year rather than assuming interchangeability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my filter housing size matches the 18-7915-1?\u003c\/strong\u003e The 18-7915-1 has a 3\/4 inch x 16 NPT thread and a 0.75 inch outside diameter; confirming these dimensions against your old filter helps verify fitment before installation.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default
