It is constructed from cellulose and steel and uses a 20mm x 1.5 thread, allowing it to thread directly onto the factory oil filter mount without adapters. Each Sierra product meets or exceeds the original equipment part it replaces, making it a direct drop-in for routine oil changes and maintenance on covered Mercury outboards.\u003c\/p\u003e\u003cp\u003eThe 18-7914 covers a wide range of Mercury outboard horsepower classes, from 25 HP through 90 HP, spanning multiple engine configurations including 3-cylinder and 4-cylinder blocks and both carbureted and EFI setups. Because coverage varies by serial number break and model year, boaters should confirm their engine's horsepower, configuration, and serial number range against the fitment list before ordering to ensure they receive the correct filter for their outboard.\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 18-7914\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 Cellulose, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Spec:\u003c\/strong\u003e 20mm x 1.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter:\u003c\/strong\u003e 20 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 3.7 x 3.2 x 3.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.58 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 filter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury 25 HP (0T800999 and lower), 1998-2006\u003c\/li\u003e\n\u003cli\u003eMercury 30 HP (0T800999 and lower), 1999-2006\u003c\/li\u003e\n\u003cli\u003eMercury 40 HP (3 cylinder), 1999-2011\u003c\/li\u003e\n\u003cli\u003eMercury 40 HP (4 cylinder), 2001-2011\u003c\/li\u003e\n\u003cli\u003eMercury 50 HP (996cc), 2001-2011\u003c\/li\u003e\n\u003cli\u003eMercury 50 HP (935cc), 1995-2000\u003c\/li\u003e\n\u003cli\u003eMercury 60 HP, 2001-2011\u003c\/li\u003e\n\u003cli\u003eMercury 75 HP Carbureted, 2000-2005\u003c\/li\u003e\n\u003cli\u003eMercury 75 HP EFI (1B366822 and below), 1999-2006\u003c\/li\u003e\n\u003cli\u003eMercury 80 HP, 2006-UP\u003c\/li\u003e\n\u003cli\u003eMercury 90 HP Carbureted, 2000-2005\u003c\/li\u003e\n\u003cli\u003eMercury 90 HP EFI (1B366822 and below), 1999-2006\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 35-822626Q2\u003c\/li\u003e\n\u003cli\u003eMercury Marine 35-822626Q04\u003c\/li\u003e\n\u003cli\u003eMercury Marine 35-822626K04\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat Mercury outboards does the Sierra 18-7914 oil filter fit?\u003c\/strong\u003e The Sierra 18-7914 fits Mercury outboards from 25 HP through 90 HP, covering configurations such as 25 HP (0T800999 and lower, 1998-2006), 30 HP (0T800999 and lower, 1999-2006), 40 HP 3-cylinder (1999-2011) and 4-cylinder (2001-2011), 50 HP 996cc (2001-2011) and 935cc (1995-2000), 60 HP (2001-2011), 75 HP Carbureted (2000-2005) and EFI 1B366822 and below (1999-2006), 80 HP (2006-UP), and 90 HP Carbureted (2000-2005) and EFI 1B366822 and below (1999-2006).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7914 a direct replacement for the Mercury OEM filter?\u003c\/strong\u003e Yes, the 18-7914 is a direct cross-reference for Mercury Marine 35-822626Q2, 35-822626Q04, and 35-822626K04, and Sierra states each filter meets or exceeds the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the 18-7914 oil filter use?\u003c\/strong\u003e It uses a 20mm x 1.5 thread with a 20 millimeter outside diameter, so it threads directly onto the factory oil filter mount on covered Mercury outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-7914 filter made of?\u003c\/strong\u003e The 18-7914 is made of cellulose and steel, a standard spin-on oil filter construction with a cellulose filtering media inside a steel canister.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-7914 oil filter weigh?\u003c\/strong\u003e The Sierra 18-7914 weighs 0.58 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-7914 oil filter?\u003c\/strong\u003e The 18-7914 measures 3.7 x 3.2 x 3.2 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes a 75 HP or 90 HP Mercury outboard always use the 18-7914?\u003c\/strong\u003e Not always;
