Instead of sourcing an impeller, housing, and key separately, this kit bundles the three components needed to rebuild the water pump section in one purchase, replacing OEM number 692-W0078-A0-00. The kit includes a water pump impeller (OE 688-44352-03-00), a water pump housing (OE 688-44311-01-00), and an impeller key (OE 90280-04M04-00), so the pump body and the wear part that drives cooling flow are addressed together rather than reusing a worn housing with a new impeller. A worn or cracked impeller and a scored housing are common causes of overheating and reduced raw water flow on outboard motors, and replacing both at once helps restore proper cooling capacity. This kit is intended for routine water pump maintenance or repair on applicable Yamaha 2-stroke outboards, and is sized and packaged as a direct kit-level replacement for the listed OEM part.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 46-46004\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type:\u003c\/strong\u003e Water Pump Kit with Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Impeller, Water Pump Housing, Impeller Key\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller OEM Number:\u003c\/strong\u003e 688-44352-03-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing OEM Number:\u003c\/strong\u003e 688-44311-01-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Key OEM Number:\u003c\/strong\u003e 90280-04M04-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Yamaha outboard motors, 2-stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080458052\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.933 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Yamaha 2-stroke outboard motors that use water pump kit 692-W0078-A0-00.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e692-W0078-A0-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the EMP 46-46004 water pump kit?\u003c\/strong\u003e The EMP 46-46004 kit includes a water pump impeller, a water pump housing, and an impeller key, giving you the full pump-side rebuild in one kit rather than separate purchases.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does this kit replace?\u003c\/strong\u003e EMP water pump kit 46-46004 replaces OEM number 692-W0078-A0-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit include the water pump housing or just the impeller?\u003c\/strong\u003e Yes, kit 46-46004 includes the water pump housing (OE 688-44311-01-00) along with the impeller and impeller key, not just the impeller alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the OEM number for the impeller in this kit?\u003c\/strong\u003e The impeller included in the EMP 46-46004 kit carries OEM number 688-44352-03-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the OEM number for the impeller key in this kit?\u003c\/strong\u003e The impeller key in kit 46-46004 corresponds to OEM number 90280-04M04-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard motors is the 46-46004 water pump kit designed for?\u003c\/strong\u003e This kit is designed for Yamaha 2-stroke outboard motors that use water pump assembly 692-W0078-A0-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the EMP 46-46004 water pump kit weigh?\u003c\/strong\u003e The EMP water pump kit 46-46004 weighs 0.933 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace the housing along with the impeller instead of just the impeller?\u003c\/strong\u003e Replacing the housing (OE 688-44311-01-00) together with the impeller, as included in kit 46-46004, addresses wear or scoring on the housing bore that a new impeller alone would not fix, helping restore proper water pump sealing and flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the impeller key a separate purchase or included with this kit?\u003c\/strong\u003e The impeller key (OE 90280-04M04-00) is included in the EMP 46-46004 kit along with the impeller and housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this product?\u003c\/strong\u003e The UPC for the EMP water pump kit 46-46004 is 840080458052.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a complete water pump repair kit or a housing-only kit?\u003c\/strong\u003e Kit 46-46004 is a complete kit with housing, meaning it includes the impeller, the housing, and the impeller key rather than just one component.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991289835739,"sku":"EMP-46-46004","price":40.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP-46-46004-Yamaha-water-pump-kit__22191.1722346045.500.750.jpg?v=1785329113","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-repair-kit-with-housing-for-yamaha-outboards-replaces-692-w0078-a0-00-mpn-46-46004","provider":"Good Vibes Marina","version":"1.0","type":"link"}
