The 19453Q2 impeller kit restores the heart of your cooling system. Its flexible elastomer impeller maintains consistent flow even at low idle or high RPM, while the included plates and seals ensure everything stays watertight. By renewing these components, you protect your outboard from overheating and maintain smooth, efficient operation.

The materials are designed to endure marine life — heat, friction, and mineral-filled water. You’ll notice a steady stream from the telltale and consistent cooling performance under all conditions. Regular replacement of this kit means peace of mind on every trip and fewer surprises when you’re far from the dock.
