EMP Water Pump Kit with Housing 46-46004, Replaces 692-W0078-A0-00, for Yamaha 2-Stroke Outboards
The EMP Water Pump Kit with Housing, part number 46-46004, is a complete water pump repair kit built for Yamaha 2-stroke outboard motors. 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.
