Installation Notes

  1. Shut off the engine and allow it to cool completely. Disconnect the boat's battery.
  2. Close the raw water intake seacock to prevent water from entering the vessel.
  3. Place an absorbent towel under the pump to catch any spilled coolant or water.
  4. Remove the screws holding the pump's cover plate. Keep them safe.
  5. Carefully pry off the cover plate. If it’s stuck, tap it gently; avoid using a screwdriver, which can damage the sealing surfaces.
  6. Note the rotational direction of the existing impeller blades before removal. Use impeller pullers or two screwdrivers to carefully lever the old impeller out.
  7. Clean the inside of the pump housing and the cover plate, removing any old gasket material or debris.
  8. Lubricate the new impeller and the inside of the pump housing with water-resistant grease or liquid soap.
  9. Install the new impeller by pushing it into the housing while twisting it in the direction of engine rotation to correctly bend the blades.
  10. Install a new gasket (not included) if required, and securely fasten the cover plate.
  11. Re-open the raw water seacock. Reconnect the battery.
  12. Start the engine and immediately check the pump and exhaust for proper water flow and any leaks.

Troubleshooting & FAQ

How do I know if this impeller fits my engine?

First, check if your existing part number is listed in our Part Number Matrix. Second, find your engine or pump model in the compatibility tables. Finally, you must verify that the physical specifications match your old part: a 12mm (15/32") shaft diameter and a slotted pin drive.

What are the signs of a failing impeller?

Common signs of a worn or damaged impeller include engine temperatures rising above normal, a noticeable reduction in water flow from the exhaust outlet, or visible cracks, stiffness, or missing blades during a visual inspection.

How often should I replace my impeller?

As a general rule, impellers should be inspected annually and replaced every 1-2 years as preventative maintenance. However, replacement frequency depends on hours of use, water conditions (sandy or silty water causes faster wear), and whether the pump has been run dry.

Does this impeller include a gasket or O-ring?

This product listing is for the impeller only. Gaskets, O-rings, and pump cover screws are not included and must be purchased separately if needed for your specific pump model.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). It has been built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, it is batch-inspected for consistency and quality.
