It is designated Water Pump Kit, Without Housing, meaning it is intended for service jobs where the existing pump housing is being reused and only the associated mounting hardware needs to be replaced or refreshed as part of a water pump rebuild.\u003c\/p\u003e\u003cp\u003eThis kit fits a range of Yamaha outboard models spanning several horsepower classes, including the T50, plain 60, C60, C70, P60, T60, and 70 designations, each tied to its own model-year window as documented by Yamaha. Because outboard water pump service intervals are tied to impeller wear and corrosion of small fasteners, using correctly sized OEM-cross-reference hardware like the 18-3465 helps ensure the pump housing seats and seals properly against the drive shaft housing during reassembly.\u003c\/p\u003e\u003cp\u003eThe kit contains two 90119-08M87-00 bolts and two 90119-08M13-00 bolts, matching Yamaha's own part numbers and quantities for this service point. As a Sierra part, it is manufactured to be an equivalent for the Yamaha original and is backed by Sierra's standard limited warranty. The kit weighs 0.55 pounds as packaged.\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 18-3465\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282226596\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 6H3-W0078-02-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Bolt 90119-08M87-00 (Qty 2); Bolt 90119-08M13-00 (Qty 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha 50-70 HP outboards (T50, 60, C60, C70, P60, T60, 70)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha T50, 1997-05\u003c\/li\u003e\n\u003cli\u003eYamaha 60, 2001-03\u003c\/li\u003e\n\u003cli\u003eYamaha C60, 1997-01\u003c\/li\u003e\n\u003cli\u003eYamaha C70, 2000-01\u003c\/li\u003e\n\u003cli\u003eYamaha P60, 1997-99\u003c\/li\u003e\n\u003cli\u003eYamaha T60, 2003-05\u003c\/li\u003e\n\u003cli\u003eYamaha 70, 1997-03\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e6H3-W0078-02-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-3465 water pump kit include the pump housing?\u003c\/strong\u003e No, the 18-3465 is designated Water Pump Kit, Without Housing, so the pump housing itself is not included; it is meant for jobs where the existing housing is reused.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM Yamaha part number does the 18-3465 replace?\u003c\/strong\u003e The 18-3465 cross-references to Yamaha OEM part number 6H3-W0078-02-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Yamaha outboard models does the 18-3465 fit?\u003c\/strong\u003e It fits the Yamaha T50 (1997-05), 60 (2001-03), C60 (1997-01), C70 (2000-01), P60 (1997-99), T60 (2003-05), and 70 (1997-03).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3465 water pump kit weigh?\u003c\/strong\u003e The 18-3465 weighs 0.55 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the 18-3465 kit?\u003c\/strong\u003e The kit includes two 90119-08M87-00 bolts and two 90119-08M13-00 bolts, matching the Yamaha OEM part numbers and quantities for this service point.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3465 a genuine Yamaha part or an aftermarket equivalent?\u003c\/strong\u003e The 18-3465 is a Sierra-manufactured part built to cross-reference and replace Yamaha OEM part 6H3-W0078-02-00, and it is covered under Sierra's warranty rather than Yamaha's.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3465 water pump kit?\u003c\/strong\u003e The UPC for the 18-3465 water pump kit is 808282226596.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-3465 fit a Yamaha 60 HP outboard?\u003c\/strong\u003e Yes, it fits several Yamaha 60 HP designations: the plain 60 (2001-03), C60 (1997-01), P60 (1997-99), and T60 (2003-05).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 18-3465 different from the Sierra 18-3466?\u003c\/strong\u003e The 18-3465 is the same core kit as the Sierra 18-3466 but is supplied without the pump housing, making it suited to jobs where the housing is being reused rather than replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat brand manufactures part number 18-3465?\u003c\/strong\u003e Part number 18-3465 is manufactured by Sierra.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3465 fit the Yamaha 70 HP outboard?\u003c\/strong\u003e Yes, it fits the Yamaha 70 (1997-03) and C70 (2000-01) models.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988149317851,"sku":"SIE-18-3465","price":31.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3465_lg__17402.1722381040.500.750.jpg?v=1785188229","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3465-water-pump-kit-without-housing-for-yamaha-50-70-hp-outboards-replaces-6h3-w0078-02-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
