Performance & Real-World Benefits

The 807151A14 sea water pump body kit ensures your MerCruiser’s cooling system operates at peak efficiency. Over time, heat, saltwater, and vibration can cause the original housing or impeller to degrade — reducing water flow and risking overheating. This OEM kit restores the full cooling performance your engine was built for.

Its resin housing is lightweight yet incredibly tough, preventing corrosion and distortion that metal housings can suffer in saltwater. The Quicksilver impeller maintains flexibility across wide temperature ranges, keeping water flowing consistently even during extended use. With everything you need in one box, it’s a straightforward fix that keeps your engine running cool and reliable.

Why Choose Mercury OEM

The Quicksilver 807151A14 isn’t just a replacement — it’s an upgrade designed and tested by the people who build the engines. Aftermarket parts might fit, but they often use cheaper materials that don’t hold up to the marine environment.

Mercury’s OEM pump kits are built for long life, corrosion resistance, and precise flow performance. They’re the same components Mercury technicians use in factory rebuilds, so you know you’re getting parts that perform exactly as intended — mile after mile, wave after wave.
