It is a round-profile seal sized for a 1.692 inch (43 mm) outer diameter and a 1.188 inch (30.2 mm) shaft, with a 0.250 inch (6.4 mm) width, making it a direct fit wherever those exact dimensions are called for. Sierra lists this seal as a universal fit part, meaning it is sized to the seal cavity itself rather than to one specific engine model, so it can be used across outboard and drive applications that share this bore, shaft, and width combination.\u003c\/p\u003e\u003cp\u003eConstruction is a standard round oil seal design intended to hold up to marine gear-case conditions and repeated duty cycles. It ships as a single seal (one count) ready to install during a lower-unit or driveshaft service, and it cross-references directly to Honda, Mercury Marine, and OMC part numbers, so it is a straightforward replacement when servicing engines built around those OEM seals.\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 18-2002\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Oil Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Prop \u0026amp; Driveshaft Seals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 1.692 inches (43 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Size:\u003c\/strong\u003e 1.188 inches (30.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.250 inches (6.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999309488\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal fit sized to the 1.692 inch outer diameter, 1.188 inch shaft, and 0.250 inch width seal cavity; not restricted to a single engine model.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHonda 91252-ZW1-003\u003c\/li\u003e\n\u003cli\u003eMercury Marine 26-76868\u003c\/li\u003e\n\u003cli\u003eOMC 320862\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2002 oil seal used for?\u003c\/strong\u003e The Sierra 18-2002 is a small oil seal used in outboard prop and driveshaft applications to keep gear lube contained and water out of the lower unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2002 fit my outboard?\u003c\/strong\u003e It is a universal fit seal sized to a 1.692 inch outer diameter, 1.188 inch shaft, and 0.250 inch width, so the 18-2002 fits any application that uses that exact seal cavity size rather than being limited to one engine model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-2002 replace a Honda oil seal?\u003c\/strong\u003e Yes, the Sierra 18-2002 cross-references directly to Honda part number 91252-ZW1-003.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2002 the same as Mercury Marine 26-76868?\u003c\/strong\u003e Yes, Mercury Marine 26-76868 is one of the OEM numbers the Sierra 18-2002 oil seal cross-references to.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this seal cross to an OMC part number?\u003c\/strong\u003e Yes, OMC 320862 is listed as an equivalent to the Sierra 18-2002 oil seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2002 oil seal?\u003c\/strong\u003e The seal measures 1.692 inches (43 mm) outer diameter, 1.188 inches (30.2 mm) shaft size, and 0.250 inches (6.4 mm) in width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2002 oil seal weigh?\u003c\/strong\u003e The Sierra 18-2002 oil seal weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the Sierra 18-2002 seal?\u003c\/strong\u003e It is a round oil seal, as listed under the 18-2002 part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many seals come in one order of 18-2002?\u003c\/strong\u003e Each order of the Sierra 18-2002 includes one oil seal (unit count of 1).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2002 an OEM or aftermarket part?\u003c\/strong\u003e The 18-2002 is a Sierra-branded replacement seal that cross-references to OEM Honda, Mercury Marine, and OMC part numbers, making it a direct aftermarket equivalent rather than an OEM-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the 18-2002?\u003c\/strong\u003e The Sierra 18-2002 is categorized as an outboard prop and driveshaft seal.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988090106075,"sku":"SIE-18-2002","price":11.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2002_lg__37035.1558121848.500.750.jpg?v=1785188121","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2002-oil-seal-replaces-mercury-26-76868-honda-91252-zw1-003-omc-320862-43mm-od-marine-oil-seal","provider":"Good Vibes Marina","version":"1.0","type":"link"}
