Description

The Mercury Impeller Housing Assembly 8M0139978 is a genuine Mercury OEM replacement component designed for select Mercury and MerCruiser cooling system applications.

The impeller housing assembly helps protect and support the water pump impeller while directing cooling water through the engine's cooling system. A worn, damaged, or corroded housing can reduce water flow and cooling efficiency, potentially leading to overheating or premature impeller wear.

Genuine Mercury service parts help ensure proper fitment, dependable performance, and compatibility compared to aftermarket alternatives.

To confirm compatibility, contact our team with your engine serial number at (727) 596-5929 before ordering.
