Performance & Practical Benefits

The 19202001 water pump gasket ensures that your cooling system stays sealed and efficient. By maintaining a tight seal between the plate and housing, it prevents pressure loss and ensures your impeller delivers steady water flow through the engine.

The composite material is designed for durability and flexibility, so it won’t crack or deform over time. This gasket helps protect your outboard from overheating and gives you consistent cooling performance — the kind of reliability you notice on hot summer days and long runs.

Why Buy OEM

Cooling system seals are no place to gamble on fit or material quality. The Quicksilver 19202001 is a genuine Mercury Marine part, precision-cut to factory dimensions for a perfect match. Off-brand gaskets can shrink, split, or fail under heat and vibration, risking leaks that lead to overheating or engine damage.

With Mercury OEM parts, you’re getting components designed to handle the specific pressures and temperatures of marine cooling systems. It’s the difference between hoping it seals and knowing it does.
