Sierra manufactures the kit to meet or exceed the original equipment part it replaces, so it is a direct, reliable substitute when the OEM seal kit is no longer available or when a shop prefers a proven aftermarket source. The kit is supplied as a complete set of gearcase seals and includes a rubber grommet (Sierra part 18-3110, O.E.# 26-38970) among its components, so a technician has the pieces needed to reseal the lower unit in a single service rather than sourcing individual seals separately.\u003c\/p\u003e\u003cp\u003eSierra parts are designed and tested to stand up to the harsh marine environment, resisting the effects of saltwater, fuel, and gear lubricant exposure over the life of the gearcase. This seal kit is intended for outboard owners, marine technicians, and repair shops performing lower unit maintenance, gearcase overhauls, or troubleshooting a leaking gearcase on Mercury and Mariner outboard motors.\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 18-2653\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 Mercury\/Mariner outboard motor gearcase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\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 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999312648\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Component:\u003c\/strong\u003e Grommet, Sierra 18-3110 (O.E.# 26-38970), Qty 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury outboard motors\u003c\/li\u003e\n\u003cli\u003eMariner outboard motors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e26-55682A1\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2653 Lower Unit Seal Kit include?\u003c\/strong\u003e The kit includes the gearcase seals needed to reseal a Mercury or Mariner outboard lower unit, including a rubber grommet (Sierra 18-3110, O.E.# 26-38970) as one of its components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich outboard motors is part number 18-2653 designed for?\u003c\/strong\u003e This seal kit is designed for Mercury and Mariner outboard motor lower units.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-2653 replace OEM part 26-55682A1?\u003c\/strong\u003e Yes, Sierra 18-2653 directly replaces OEM number 26-55682A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2653 seal kit weigh?\u003c\/strong\u003e The Sierra 18-2653 Lower Unit Seal Kit weighs 0.28 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the seals made from?\u003c\/strong\u003e The seals in kit 18-2653 are made of rubber.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-2653 seal kit?\u003c\/strong\u003e The components in this kit are white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-2653 a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e 18-2653 is a Sierra aftermarket part manufactured to meet or exceed the original equipment part it replaces, rather than a Mercury-branded OEM part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to install the 18-2653 seal kit?\u003c\/strong\u003e This kit is used during a lower unit gearcase rebuild or reseal service on a Mercury\/Mariner outboard, such as when old seals are worn, leaking, or being replaced preventively.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the shape of the seal components in this kit?\u003c\/strong\u003e The seal components included in the Sierra 18-2653 kit are round.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the grommet included in 18-2653 a separate purchasable part?\u003c\/strong\u003e Yes, the grommet included in this kit is also sold individually as Sierra part 18-3110, with O.E.# 26-38970.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2653 Lower Unit Seal Kit?\u003c\/strong\u003e The UPC for this kit is 030999312648.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988108357851,"sku":"SIE-18-2653","price":86.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2653_lg__35625.1558124454.500.750.jpg?v=1785188649","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2653-lower-unit-seal-kit-replaces-mercury-26-55682a1-for-mercury-mariner-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
