Performance & Practical Benefits

When water pump parts wear, cooling performance drops — and that can mean trouble for your outboard. The 19453T2 repair kit gives your pump a complete refresh, restoring proper pressure and flow to keep the engine cool and efficient.

The impeller’s flexible vanes maintain steady flow, even in hot or shallow-water conditions, while the stainless plate and gaskets ensure a clean, watertight seal. Regular replacement with this kit prevents overheating, improves reliability, and extends the life of your Mercury engine. It’s a small job that delivers big peace of mind every time you leave the dock.

The Mercury 19453T2 is a genuine OEM repair kit, designed for the specific cooling system found in Mercury TwoStroke outboards. Every part is tested for flow rate, heat resistance, and long-term durability.

With OEM parts, you know you’re getting the exact tolerances and quality that Mercury engineers intended — no adjustments, no second-guessing. It’s the reliable fix that keeps your cooling system performing like new.
