It is built for boat owners and marine technicians who need to restore proper cooling water flow to the engine without replacing a housing that is already in good condition. The kit's impeller compound is formulated based on the size and application of this specific pump, and the remaining kit components are constructed to meet or exceed original equipment specifications. This kit is functionally the same as the Sierra 18-3412 kit, with the difference being that 18-3433 omits the housing, making it the correct choice when the existing housing is being reused or sourced separately.\u003c\/p\u003e\u003cp\u003eThe kit includes the mounting bolt (O.E. 97095-08045-00, qty 4) needed to complete the water pump service, along with the additional gasket and seal components required for a proper installation. It is designed as a maintenance and repair part for Yamaha outboard engines within the stated fitment range, restoring the water pump function that circulates cooling water through the engine.\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 18-3433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 63V-W0078-01-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha 9.9\/15 HP (1996-04); Yamaha F15 (1998-04)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Bolt, O.E. 97095-08045-00, Qty 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282185671\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eYamaha 9.9\/15 HP outboards, 1996-04\u003c\/li\u003e\n\u003cli\u003eYamaha F15 outboards, 1998-04\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e63V-W0078-01-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3433 water pump kit fit?\u003c\/strong\u003e The 18-3433 kit fits Yamaha 9.9\/15 HP outboards from 1996-04 and Yamaha F15 outboards from 1998-04.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3433 kit include the pump housing?\u003c\/strong\u003e No, Sierra 18-3433 is supplied without housing, so it is intended for installations where the existing housing is reused or sourced as a separate part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does 18-3433 replace?\u003c\/strong\u003e Sierra 18-3433 replaces Yamaha OEM number 63V-W0078-01-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3433 water pump kit weigh?\u003c\/strong\u003e The kit weighs 0.37 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-3433 kit?\u003c\/strong\u003e The kit includes a mounting bolt (O.E. 97095-08045-00, qty 4) along with the other components needed to service the water pump, aside from the housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between Sierra 18-3433 and 18-3412?\u003c\/strong\u003e 18-3433 and 18-3412 are the same water pump kit, except 18-3433 does not include the pump housing while 18-3412 does.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3433 kit a genuine Yamaha part or an aftermarket replacement?\u003c\/strong\u003e The 18-3433 is a Sierra-brand aftermarket kit built to replace Yamaha OEM part 63V-W0078-01-00, not a Yamaha-branded part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill 18-3433 work if my boat's water pump housing is still good?\u003c\/strong\u003e Yes, since Sierra 18-3433 is sold without housing, it is well suited to a rebuild where the existing housing does not need to be replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3433 impeller sized specifically for this application?\u003c\/strong\u003e Yes, the impeller compound in the 18-3433 kit is formulated based on the size and application of this specific Yamaha water pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3433 water pump kit?\u003c\/strong\u003e The UPC for Sierra 18-3433 is 808282185671.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988148433115,"sku":"SIE-18-3433","price":23.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3433_lg__34912.1558126901.500.750.jpg?v=1785189066","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3433-water-pump-kit-no-housing-for-yamaha-9-9-15-f15-outboards-replaces-63v-w0078-01-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
