It is assembled in Sierra's Illinois factory to OEM-quality standards, so every seal is engineered for the specific application it is designed to fit rather than sold as a generic, one-size-fits-all part. This kit gives outboard owners and marine technicians the seals needed to rebuild or service the lower unit gear housing, restoring the water-tight and oil-tight barriers that keep gear lube in and water out during operation.\u003c\/p\u003e\u003cp\u003eBecause lower unit seals are wear items subject to constant exposure to gear oil, water pressure, and heat, replacing them as a set during a lower unit rebuild or gearcase service helps prevent water intrusion and gear lube contamination, which are common causes of lower unit failure. The kit is packaged as a single unit count, ready to install as part of a routine lower unit service or repair.\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 18-2681\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\u003eFits:\u003c\/strong\u003e Johnson\/Evinrude Outboard Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e GLM 87617\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\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999562807\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00030999562807\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis seal kit is designed for Johnson\/Evinrude outboard motors.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eGLM 87617\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2681 Lower Unit Seal Kit include?\u003c\/strong\u003e It includes the seals needed to rebuild the gear housing of a Johnson\/Evinrude outboard lower unit, packaged as a single kit with a unit count of one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich outboard motors is the 18-2681 seal kit designed for?\u003c\/strong\u003e The 18-2681 kit is designed to fit Johnson\/Evinrude outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-2681 replace GLM 87617?\u003c\/strong\u003e Yes, the Sierra 18-2681 lower unit seal kit is a direct replacement for GLM 87617.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2681 seal kit weigh?\u003c\/strong\u003e The Sierra 18-2681 Lower Unit Seal Kit weighs 0.09 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this an OEM Sierra part or an aftermarket copy?\u003c\/strong\u003e The 18-2681 is a genuine Sierra part, assembled in Sierra's Illinois factory to OEM-quality standards rather than being a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color are the seals in this kit?\u003c\/strong\u003e The seals in the Sierra 18-2681 kit are white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to install this seal kit?\u003c\/strong\u003e This kit is used when rebuilding or servicing the gear housing of a Johnson\/Evinrude outboard lower unit, typically during a scheduled lower unit rebuild or after a water-intrusion issue.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape are the seals in the 18-2681 kit?\u003c\/strong\u003e The seals included in the Sierra 18-2681 kit are round.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace lower unit seals as a full kit instead of individually?\u003c\/strong\u003e Replacing all the seals together, as in the Sierra 18-2681 kit, ensures the entire gear housing is resealed at once, which helps prevent water intrusion and gear lube contamination that can occur if only one worn seal is replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2681 seal kit?\u003c\/strong\u003e The UPC for the Sierra 18-2681 Lower Unit Seal Kit is 030999562807.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many seal kits come in one package?\u003c\/strong\u003e One Sierra 18-2681 Lower Unit Seal Kit is included per unit, with a unit count of 1.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988108718299,"sku":"SIE-18-2681","price":46.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2681_lg__68008.1558123017.500.750.jpg?v=1785189151","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2681-lower-unit-seal-kit-for-johnson-evinrude-outboards-replaces-glm-87617","provider":"Good Vibes Marina","version":"1.0","type":"link"}
