NEW-OEM Yamaha Outboard Upper Water Pump Housing 63D-44311-00-00 | 40HP 50HP 60HP Cooling Parts

Product Description

Keep your marine engine running cool and operating at peak performance with this genuine OEM Yamaha Outboard Upper Water Pump Housing (Part Number: 63D-44311-00-00). As a foundational component of your outboard’s cooling system, this upper housing maintains the critical water pressure required to circulate fresh water through your engine block, protecting it from catastrophic overheating.

Over time, friction from sand, silt, and salt can score or warp the internal walls of your original pump housing, causing a drop in water flow and pressure cavitation. Built to Yamaha's precise factory specifications, this heavy-duty replacement housing ensures an airtight seal and flawless impeller rotation. It is the perfect direct-fit solution for routine water pump maintenance or a complete cooling system overhaul on 40HP, 50HP, and 60HP Yamaha outboard motors.
