MOOSE RACING Water Pump Seal - Polaris/Honda 503003

Water pump seal failure is one of the most common causes of mid-season breakdowns in Polaris and Honda powersports applications. A worn or degraded seal allows coolant to leak past the pump shaft, leading to overheating, potential engine damage, and costly downtime. The MOOSE RACING Water Pump Seal (503003) gives you a direct replacement that restores the integrity of your cooling system without replacing the entire pump assembly.

This mechanical seal is engineered to OEM specifications and is available separately, making it ideal for upgrading existing gasket kits or performing targeted repairs. Whether you're rebuilding a complete engine or addressing a specific cooling system issue, this seal delivers reliable performance at a fraction of a full pump replacement.
