Product Overview
This outboard water pump impeller repair kit is designed as a replacement cooling system service kit for compatible 2-stroke 9.9HP and 15HP outboard engines, as well as compatible 4-stroke 9.9HP F9.9 and T9.9 outboard engines from 1985 to 2005 using part number 682-W0078.
The water pump impeller helps move cooling water through the outboard engine to support proper engine temperature control. A worn, cracked, or damaged impeller may reduce water flow and increase the risk of overheating, especially during extended marine use.
Built for harsh marine environments, this repair kit is suitable for routine outboard cooling system maintenance or replacement of worn water pump components. Please compare the part number, impeller size, housing size, bolt dimensions, gasket shape, and product photos with your original parts before ordering.
