Overview / What Is Water Pump Kit, W/O Housing for Marine Engines

A Water Pump Kit W/O Housing for marine is an assembly of critical parts excluding the metal or plastic upper housing of the pump. It’s primarily used when the existing housing is in good condition and doesn’t require replacement. The core components included are the impeller, wear plate, key, gaskets, o-rings, and sometimes bolts or pins.

This kit is designed to maintain the boat engine’s cooling system by circulating water through the engine. Without proper circulation, the engine can overheat, leading to costly repairs or total failure. By replacing worn internal parts while retaining the original housing, boaters can perform economical and effective repairs.
