Performance & Practical Benefits

The 192043 water pump base gasket seals the foundation of your cooling system, preventing leaks and ensuring efficient water circulation. When this gasket wears or fails, your pump can lose pressure, reducing cooling capacity and raising engine temperatures. Replacing it restores full performance and helps protect your engine from overheating.

This OEM gasket is designed to compress evenly, maintaining its shape through repeated heating and cooling cycles. It installs cleanly with the rest of your water pump components and provides that perfect fit and feel that only Mercury parts deliver.

Why Buy OEM

A proper seal depends on exact dimensions and materials — something you only get with genuine Mercury Marine parts. The Quicksilver 192043 is built to Mercury’s original specs, ensuring it won’t shrink, split, or leak like many aftermarket gaskets.

Mercury’s marine-grade materials are engineered for long life under constant exposure to water, vibration, and heat. It’s a small, affordable part, but one that keeps your engine running cool and your water pump working at its best.
