Performance & Real-World Benefits

The 43026Q02 impeller ensures your cooling system gets steady, uninterrupted water flow — essential for powerful, high-output engines. Its flexible blades maintain proper seal and pressure inside the pump housing, helping prevent overheating during long runs or high-speed operation.

The reinforced hub resists tearing and fatigue, while the marine-grade elastomer stays pliable through temperature swings. With this impeller installed, you’ll get consistent cooling, longer component life, and the peace of mind that your engine is protected when you push it hardest.

Why Choose Mercury OEM

The Quicksilver 43026Q02 is a genuine Mercury Marine part, built to the exact specs your Verado or Racing outboard requires. Aftermarket impellers can vary slightly in dimensions or material flexibility, which can reduce flow efficiency and shorten service life.

Mercury OEM impellers are tested under the same high-performance conditions as the engines they serve. With factory-grade materials, precision molding, and proven durability, they deliver cooling performance you can count on — no matter how hard you run.
