It supplies the oil seals needed to reseal the lower unit and prevent gear lube from escaping or water from entering the gear case, a common maintenance need any time the lower unit is opened up for service or after a water-intrusion issue is diagnosed. The kit contains two individually numbered oil seals: the 18-2059 oil seal (O.E. 321466) and the 18-2064 oil seal (O.E. 332205), each manufactured to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eUsing the correct seal kit during a lower unit rebuild helps maintain a proper gear lube seal, which protects the gear case from corrosion and premature wear caused by water contamination. The kit is designed as a direct replacement for the original Johnson\/Evinrude part 396349, so it drops into the same lower unit assembly without modification. It is intended for outboard owners and marine technicians performing lower unit reseals, gear case rebuilds, or preventive maintenance on Johnson\/Evinrude outboards.\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 18-2660\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Lower Unit Seal Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContains:\u003c\/strong\u003e 18-2059 Oil Seal (O.E. 321466), 18-2064 Oil Seal (O.E. 332205)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999312716\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e396349\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2660 Lower Unit Seal Kit include?\u003c\/strong\u003e The kit includes two oil seals: an 18-2059 oil seal (O.E. 321466) and an 18-2064 oil seal (O.E. 332205), both intended for resealing the lower unit gear housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard motors does the 18-2660 seal kit fit?\u003c\/strong\u003e This seal kit is designed for Johnson and Evinrude outboard motors that use the 396349 lower unit seal kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2660 a direct replacement for OEM part 396349?\u003c\/strong\u003e Yes, the 18-2660 kit replaces the original Johnson\/Evinrude part number 396349 and is built to meet or exceed the quality of the original equipment part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2660 seal kit weigh?\u003c\/strong\u003e The Sierra 18-2660 Lower Unit Seal Kit weighs 0.22 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color are the seals in the 18-2660 kit?\u003c\/strong\u003e The seals in this kit are white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I install a lower unit seal kit like the 18-2660?\u003c\/strong\u003e A lower unit seal kit such as the 18-2660 should be installed any time the gear housing is opened for service, or when gear lube is found to be contaminated with water, indicating a failed seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the seals in the 18-2660 kit genuine OEM parts?\u003c\/strong\u003e No, the Sierra 18-2660 is an aftermarket seal kit manufactured to meet or exceed the quality of the original equipment seals it replaces, rather than being sourced from Johnson\/Evinrude directly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the shape of the oil seals in the 18-2660 kit?\u003c\/strong\u003e Both oil seals included in the Sierra 18-2660 kit are round in shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2660 kit include gaskets or just seals?\u003c\/strong\u003e The 18-2660 kit contains two oil seals, the 18-2059 and 18-2064, and does not list any gaskets as included components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2660 Lower Unit Seal Kit?\u003c\/strong\u003e The UPC for the Sierra 18-2660 Lower Unit Seal Kit is 030999312716.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988108554459,"sku":"SIE-18-2660","price":51.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2660_lg__06158.1558124972.500.750.jpg?v=1785188504","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2660-lower-unit-seal-kit-for-johnson-evinrude-outboards-replaces-oem-0396349-glm-87601-mallory-9-74103","provider":"Good Vibes Marina","version":"1.0","type":"link"}
