It replaces the OEM Yamaha part 688-W0001-22-00 and is built to match the fit, form, and function of the original equipment seals it succeeds, making it a direct drop-in choice for a gear housing rebuild or seal replacement job.\u003c\/p\u003e\u003cp\u003eThis kit fits the Yamaha C75 (1994-99), E75 (1995-00), P75 (1996-99), C80 (1997), C85 (1992-96), 90 (1992-02), B90 (1998-99), and C90 (1997-01) outboard models. Because gear housing seals are a wear item exposed to constant water contact and gear lubricant, replacing them at the correct interval, or any time the lower unit is opened up, helps prevent water intrusion into the gear case and lubricant leakage that can lead to bearing and gear damage. The kit is sold under the Sierra brand, a long-established supplier of outboard replacement parts, and is packaged as a complete set so the seals needed for the job are included together rather than sourced individually.\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 18-0021\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Gear Housing Seal Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 688-W0001-22-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha C75 (1994-99), E75 (1995-00), P75 (1996-99), C80 (1997), C85 (1992-96), 90 (1992-02), B90 (1998-99), C90 (1997-01)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.36 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282161132\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha C75 (1994-99)\u003c\/li\u003e\n\u003cli\u003eYamaha E75 (1995-00)\u003c\/li\u003e\n\u003cli\u003eYamaha P75 (1996-99)\u003c\/li\u003e\n\u003cli\u003eYamaha C80 (1997)\u003c\/li\u003e\n\u003cli\u003eYamaha C85 (1992-96)\u003c\/li\u003e\n\u003cli\u003eYamaha 90 (1992-02)\u003c\/li\u003e\n\u003cli\u003eYamaha B90 (1998-99)\u003c\/li\u003e\n\u003cli\u003eYamaha C90 (1997-01)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e688-W0001-22-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0021 Gear Housing Seal Kit fit?\u003c\/strong\u003e The 18-0021 kit fits the Yamaha C75 (1994-99), E75 (1995-00), P75 (1996-99), C80 (1997), C85 (1992-96), 90 (1992-02), B90 (1998-99), and C90 (1997-01) outboard models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does this seal kit replace?\u003c\/strong\u003e It replaces Yamaha OEM part number 688-W0001-22-00, so it is a direct substitute for that original gear housing seal set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0021 an OEM part or an aftermarket replacement?\u003c\/strong\u003e It is an aftermarket replacement kit made to match the fit, form, and function of the original Yamaha 688-W0001-22-00 gear housing seal set.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0021 kit weigh?\u003c\/strong\u003e The Sierra 18-0021 Gear Housing Seal Kit weighs 0.36 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this kit work on a Yamaha 90 outboard?\u003c\/strong\u003e Yes, the 18-0021 kit is designed to fit the Yamaha 90 (1992-02) outboard, along with the C75, E75, P75, C80, C85, B90, and C90 models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the 18-0021 kit?\u003c\/strong\u003e The kit includes the gear housing seals needed to service the lower unit of the covered Yamaha outboard models, sold as a Sierra Gear Housing Seal Kit under part number 18-0021.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should the gear housing seals be replaced?\u003c\/strong\u003e Gear housing seals like those in the 18-0021 kit should be replaced any time the lower unit is opened for service, or when water intrusion or gear lubricant leakage is suspected.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Yamaha C90 use the same seal kit as the C85?\u003c\/strong\u003e Yes, the Sierra 18-0021 Gear Housing Seal Kit covers both the C85 (1992-96) and the C90 (1997-01), along with several other Yamaha models listed in its fitment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the UPC for the 18-0021 kit 808282161132?\u003c\/strong\u003e Yes, the Sierra Gear Housing Seal Kit 18-0021 carries UPC 808282161132.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this kit be used on a Yamaha E75 outboard?\u003c\/strong\u003e Yes, the E75 (1995-00) is one of the Yamaha models covered by the Sierra 18-0021 Gear Housing Seal Kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand makes part number 18-0021?\u003c\/strong\u003e Part number 18-0021 is manufactured by Sierra as a Gear Housing Seal Kit.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988012151003,"sku":"SIE-18-0021","price":54.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0021_lg__44598.1558119184.500.750.jpg?v=1785188101","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0021-gear-housing-seal-kit-replaces-yamaha-688-w0001-22-00-fits-c75-c80-c85-c90-90-hp-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
