It supplies the housing along with the components needed to restore proper water flow to the powerhead, helping prevent overheating that can occur once an original pump housing wears, cracks, or corrodes. Because the kit includes the housing itself rather than just the wear parts, it is intended for situations where the original housing is damaged, warped, or no longer sealing correctly, giving a more complete and reliable repair than an impeller-only kit.\u003c\/p\u003e\u003cp\u003eSierra manufactures this kit to match the specifications of the outboard water pump systems it is built for, so the housing and included hardware are sized to install as a unit. This makes it a straightforward option for routine maintenance or for a full pump rebuild when servicing the lower unit. The kit ships as a single count unit and is cataloged under Sierra's marine engine parts line for Yamaha outboard applications.\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 18-3522-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit with Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.82 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Boat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Application:\u003c\/strong\u003e Yamaha 2-Stroke Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282362133\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282362133\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Water Pump Kit with Housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Yamaha 2-stroke outboard motors.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-3522-1 water pump kit?\u003c\/strong\u003e The kit includes the water pump housing along with the components needed for a complete pump rebuild, listed as a single included-components unit for part number 18-3522-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-3522-1 water pump kit fit?\u003c\/strong\u003e This Sierra kit is built for Yamaha 2-stroke outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit come with the housing or just the impeller?\u003c\/strong\u003e It comes with the housing included, not just the impeller, since 18-3522-1 is a water pump kit with housing rather than an impeller-only kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-3522-1 water pump kit weigh?\u003c\/strong\u003e It weighs 0.82 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in one package?\u003c\/strong\u003e The unit count for the Sierra 18-3522-1 kit is 1, meaning one complete water pump kit with housing per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or an aftermarket copy?\u003c\/strong\u003e It is a genuine Sierra-branded part, manufactured and sold under Sierra's own part number 18-3522-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace the housing instead of just the impeller?\u003c\/strong\u003e When the original pump housing is cracked, warped, or no longer sealing properly, replacing it along with the wear components, as this kit does, restores reliable water flow better than swapping the impeller alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The UPC for the Sierra 18-3522-1 water pump kit is 808282362133.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this kit for a 2-stroke or 4-stroke Yamaha outboard?\u003c\/strong\u003e It is designed for Yamaha 2-stroke outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat vehicle type is this part designed for?\u003c\/strong\u003e It is designed for boats, listed with a vehicle service type of Boat.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988150694107,"sku":"SIE-18-3522-1","price":88.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-3522-1__78165.1722499807.500.750.jpg?v=1785188407","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-3522-1-water-pump-kit-with-housing-for-yamaha-50-70-hp-outboards-t50-c60-t60-70-c70-replaces-6h3-w0078-01-6h3-44311-00","provider":"Good Vibes Marina","version":"1.0","type":"link"}
