Performance & Real-World Benefits

The 59362T1 impeller ensures your MerCruiser’s cooling system delivers the steady water flow your engine depends on. Each vane flexes smoothly with every rotation, keeping pressure consistent and preventing air pockets that can lead to overheating.

Its bonded insert design locks the vanes firmly in place, so it won’t lose water flow under load. Built for performance and durability, it helps extend engine life by maintaining ideal operating temperatures through every season.

Why Choose Mercury OEM

The Quicksilver 59362T1 is a genuine Mercury Marine impeller, engineered specifically for your MerCruiser cooling system. Aftermarket versions can look similar but often use harder rubber or poor bonding, which can cause early wear and reduced flow.

Mercury’s OEM impellers are precision-molded and tested for flexibility, balance, and endurance in real marine conditions. Choosing OEM gives you a part that fits perfectly, performs flawlessly, and protects your investment.
