Product Overview
This outboard water pump impeller repair kit is designed as a replacement cooling system service kit for compatible 2-stroke and 4-stroke 4HP and 5HP outboard engines using part number 6E0-W0078.
The water pump impeller helps circulate cooling water through the outboard engine, supporting proper engine temperature control during operation. A worn, cracked, or damaged impeller may cause weak water flow, overheating, poor cooling performance, or engine damage if not replaced in time.
Built for marine use, this repair kit is designed to withstand harsh water, moisture, and outdoor operating conditions. Please compare the part number, impeller size, housing size, bolt dimensions, and product photos with your original water pump parts before ordering.
