MerCruiser Water Distribution Housings

MerCruiser water distribution housings efficiently and evenly distribute water throughout your boat’s engine, ensuring that it continues to run cool even after hours of use. Afterward, that same distribution housing helps drain water out of your boat's engine to prevent freezing damage from occurring during the cold winter months.

A common requirement for all internal combustion engines, whether they operate on land or in the water, is that they require a cooling system to prevent overheating while in use. Choose NuWave Marine for the quality replacement parts that will keep your boat on the water all season long.

MerCruiser Water Distribution Housing Function

MerCruiser water distribution housings fulfill a critical role in protecting the health of your boat’s engine. First, they assist in the distribution of cooling water throughout the engine, preventing overheating damage. Second, they help in draining that system of water during the colder times of the year.

When water freezes into ice, it expands. If this expansion occurs inside the pipes of your boat’s cooling system, it can cause them to crack, incurring an expensive repair bill. The MerCruiser 350 Mag water distribution housing efficiently drains water out of the engine when it’s not needed, preventing this damage from occurring.

MerCruiser 350 MAG MPI Water Distribution Housing

Designed to work with the MerCruiser 350 MAG MPI engine, this water distribution housing features a convenient single-point drainage system, ensuring that there is less confusion when trying to drain the cooling system, and that you avoid accidentally unsealing the engine’s fuel system. Supported by rod actuation that helps clear blockages and ensure your cooling system is completely drained, this water distribution housing will keep your boat’s engine healthy all year round.
