Installation Notes

  1. Shut off the engine and close the raw water intake seacock.
  2. Place an absorbent towel under the pump to catch any spilled coolant.
  3. Remove the water pump cover plate and gasket.
  4. Gently remove the old impeller using needle-nose pliers or impeller puller tools. Avoid damaging the pump housing.
  5. Clean the inside of the pump housing and inspect for scoring or wear.
  6. Lubricate the new impeller and the inside of the pump housing with a suitable lubricant (e.g., glycerin or dish soap).
  7. Insert the new impeller, rotating the shaft in the direction of engine operation to bend the blades correctly.
  8. Install the new gasket and O-ring as required, then reinstall the cover plate.
  9. Open the seacock, start the engine, and immediately check for leaks and proper water flow.

Troubleshooting & FAQ

How do I know if this impeller fits my engine?

This impeller fits a wide range of models. The best way to confirm is to check your engine's service manual for the OEM part number and compare it against our Part Number Matrix. You can also match the dimensions (Diameter: 51mm, Width: 22mm, Shaft: 12mm) to your old part.

What are the signs of a failing impeller?

Common signs include engine overheating, reduced water flow from the exhaust, visible cracks or missing blades on the impeller, or a stiff and brittle feel to the rubber. Regular inspection is recommended.

How often should I replace my impeller?

As a general rule, replace your water pump impeller every year or every 100-200 hours of engine operation, whichever comes first. This interval can be shorter in water with high levels of sand or sediment.

My engine is still overheating after replacing the impeller. What's next?

If overheating persists, check for other blockages in the cooling system. Common issues include clogged intake strainers, heat exchangers, exhaust manifolds, or worn pump housing (cam). Ensure the seacock is fully open.

The new impeller seems difficult to install. Is this normal?

Yes, a new impeller should fit snugly. Proper lubrication is key. Applying a water-based lubricant like glycerin or dish soap to the housing and impeller will make installation much easier. Bend the blades in the direction of the pump's rotation as you insert it.

What kind of lubricant should I use?

Use a water-soluble lubricant such as glycerin or a light-viscosity dish soap. Do not use petroleum-based grease or oils, as they can cause the neoprene material to break down prematurely.
