Performance & Real-World Benefits

The 59362T6 impeller kit keeps your cooling system performing like new. The impeller blades flex with every rotation, maintaining a strong, consistent seal that keeps water moving through your engine. This ensures stable operating temperatures, smoother running, and better protection from overheating.

The included wear plate and o-rings make this a full-service kit — no guessing, no mismatched parts. It’s an easy, affordable way to prevent cooling issues and extend the life of your MerCruiser’s engine and pump assembly.

Why Choose Mercury OEM

The Quicksilver 59362T6 is a genuine Mercury Marine kit, engineered for precision and tested for marine performance. Aftermarket kits might use harder rubber or incorrect sizing, which can reduce water flow or wear out prematurely.

Mercury OEM impellers are built to withstand real boating conditions — from saltwater exposure to long hours at high RPM. Choosing OEM means you’re getting the same quality, fit, and reliability that Mercury designed for your engine from day one.
