Performance & Real-World Benefits

The 72774A32 housing provides strong protection against corrosion where it’s needed most — inside your cooling system. Brass resists pitting and salt damage, keeping coolant flow consistent and your pump assembly running efficiently.

Swapping out a corroded or worn housing restores proper sealing and pressure, helping your engine maintain the right operating temperature. It’s a smart, long-term fix that prevents costly failures caused by leaks or overheating.

Why Choose Mercury OEM

The Quicksilver 72774A32 is a genuine Mercury Marine part, made to the same quality standards as the original factory housing. Aftermarket options may use lower-grade alloys that corrode quickly or fail under heat and pressure.

Mercury’s OEM components are pressure-tested and precision-machined for durability, cooling efficiency, and exact fit. Choosing OEM means fewer worries and more time enjoying your boat, season after season.
