It bundles the shift rod gasket and oil seal needed to reseal the lower unit and restore a proper barrier against water intrusion and gear lube leakage during a gear case service or rebuild. Each component is engineered as a direct, precise-fit replacement so the kit installs the same way as the original hardware it replaces.\u003c\/p\u003e\u003cp\u003eThe kit includes a shift rod gasket that seals around the shift rod bore where it passes through the gear housing, plus an oil seal that keeps gear lubricant contained within the lower unit while blocking water from entering. Both parts are cross-referenced to their original equipment numbers so you can confirm you are ordering the correct replacement for your lower unit rebuild.\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 18-2686\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Lower Unit Seal Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson\/Evinrude Outboard Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Shift Rod Gasket (Sierra 18-0882), Oil Seal (Sierra 18-2005)\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 030999562852\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motors using this lower unit seal configuration; confirm your engine's part numbers before ordering, as fit is application specific.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e304764\u003c\/li\u003e\n\u003cli\u003e313284\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2686 Lower Unit Seal Kit include?\u003c\/strong\u003e The kit includes a shift rod gasket (Sierra 18-0882) and an oil seal (Sierra 18-2005) for resealing the lower unit gear housing on a Johnson\/Evinrude outboard motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does this kit replace?\u003c\/strong\u003e Sierra 18-2686 replaces OEM numbers 304764 and 313284, corresponding to the shift rod gasket and oil seal in the kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2686 kit OEM quality?\u003c\/strong\u003e Yes, Sierra lower unit seal kits like the 18-2686 are engineered and manufactured to meet or exceed original equipment quality and fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2686 seal kit weigh?\u003c\/strong\u003e The Sierra 18-2686 Lower Unit Seal Kit weighs 0.11 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the 18-2686 seal kit designed for?\u003c\/strong\u003e This kit is designed for Johnson\/Evinrude outboard motors; confirm your engine's specific part numbers to ensure proper fit before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the shift rod gasket's OEM equivalent number?\u003c\/strong\u003e The shift rod gasket included in kit 18-2686 (Sierra 18-0882) is the equivalent of OEM number 304764.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the oil seal's OEM equivalent number?\u003c\/strong\u003e The oil seal included in kit 18-2686 (Sierra 18-2005) is the equivalent of OEM number 313284.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need the 18-2686 lower unit seal kit?\u003c\/strong\u003e This kit is used when servicing or rebuilding the lower unit gear housing on a Johnson\/Evinrude outboard, replacing the shift rod gasket and oil seal to stop leaks and keep water out of the gear case.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color and shape is the oil seal in this kit?\u003c\/strong\u003e The oil seal in the Sierra 18-2686 kit is white and round in shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2686 kit come with installation instructions?\u003c\/strong\u003e The kit ships as the seal components themselves (shift rod gasket and oil seal) for installation during a standard lower unit reseal or rebuild procedure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2686 seal kit?\u003c\/strong\u003e The UPC for the Sierra 18-2686 Lower Unit Seal Kit is 030999562852.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988109045979,"sku":"SIE-18-2686","price":26.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2686_lg__47684.1558123309.500.750.jpg?v=1785188130","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2686-lower-unit-seal-kit-for-johnson-evinrude-outboards-replaces-oe-313284-304764","provider":"Good Vibes Marina","version":"1.0","type":"link"}
