This seal is a wear item that keeps gear case and powerhead lubricants contained while blocking water intrusion at the shaft, protecting internal components from corrosion and premature failure. It is built from a glass-filled seal material for durability in a marine environment, with a green-brown finish. The seal measures 5 x 4 x 1 inches as packaged and weighs 0.04 pounds, making it a small, precision-fit component rather than a bulk part. Because Evinrude used many serial number breakpoints across the 85-110 hp model years, buyers should confirm their engine's serial number against the ranges listed below before ordering to ensure correct fitment, including the two distinct upper O-ring configurations (round vs. Square) used on later 100 hp four-cylinder units. Sierra 18-2016 cross-references directly to Mercury Marine 26-41953 and OMC 313992, so it is a suitable replacement wherever either of those part numbers is called for.\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 18-2016\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Oil Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Green Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 5 x 4 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999309624\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury Marine 26-41953, OMC 313992\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e85 hp (850), 6-cylinder, serial 1460999-1464848\u003c\/li\u003e\n\u003cli\u003e85 hp (850), 6-cylinder, serial 1566240-1766823\u003c\/li\u003e\n\u003cli\u003e85 hp (850), 4-cylinder, serial 3493913-4831998\u003c\/li\u003e\n\u003cli\u003e90 hp (900), 6-cylinder, serial 1766824-1869775\u003c\/li\u003e\n\u003cli\u003e90 hp (90, 900), 6-cylinder, serial 4845301 and up\u003c\/li\u003e\n\u003cli\u003e90 hp, 3-cylinder, serial A996142-B240450\u003c\/li\u003e\n\u003cli\u003e90 hp, 3-cylinder, serial B240451-C221999\u003c\/li\u003e\n\u003cli\u003e90 hp, 3-cylinder, serial C222000 and up\u003c\/li\u003e\n\u003cli\u003e95 hp (950), 6-cylinder, serial 1869776-2318585\u003c\/li\u003e\n\u003cli\u003e100 hp (1000), 6-cylinder, serial 1464949-2318585\u003c\/li\u003e\n\u003cli\u003e100 hp (1000SS), 6-cylinder, serial 2318586-2413847\u003c\/li\u003e\n\u003cli\u003e100 hp (1000SS), 6-cylinder, serial 2484633-2836018\u003c\/li\u003e\n\u003cli\u003e100 hp (1000BP), 6-cylinder, serial 2399698-2641854\u003c\/li\u003e\n\u003cli\u003e100 hp (1000BP), 6-cylinder, serial 2641855-3253111\u003c\/li\u003e\n\u003cli\u003e100 hp, 4-cylinder, serial B209468-G760299\u003c\/li\u003e\n\u003cli\u003e100 hp, 4-cylinder with round upper O-ring, serial G760300 and up\u003c\/li\u003e\n\u003cli\u003e100 hp, 4-cylinder with square upper O-ring, serial G760300 and up\u003c\/li\u003e\n\u003cli\u003e110 hp (1100), serial 1870201-2314955\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 26-41953\u003c\/li\u003e\n\u003cli\u003eOMC 313992\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2016 oil seal fit?\u003c\/strong\u003e The Sierra 18-2016 fits Evinrude outboard motors from 85 hp through 110 hp, spanning 3-cylinder, 4-cylinder, and 6-cylinder engine blocks across specific serial number ranges, so confirming your engine's serial number against the listed ranges is the best way to verify fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-2016 the same as Mercury 26-41953?\u003c\/strong\u003e Yes, Sierra 18-2016 cross-references directly to Mercury Marine 26-41953, so it can be used as a replacement wherever that Mercury number is specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-2016 replace OMC 313992?\u003c\/strong\u003e It does.
