Installation Guide

Note: Early model P102 and P105 pumps prior to 1993 used a different gasket and end cover size. This kit includes the gasket for newer pumps. Verify your pump model and year before starting work.

1. Turn off the engine and disconnect the battery. Close the raw water intake seacock.
2. Place a catch pan under the pump to collect any spilled coolant or water.
3. Loosen the hose clamps and remove the intake and outlet hoses from the pump.
4. Remove the pump cover screws and take off the cover plate.
5. Pry out the old impeller using pliers or impeller pullers. Remove the old gasket or O-ring.
6. Remove the retaining rings and press out the old bearings and lip seal from the pump housing.
7. Clean the interior of the pump housing, especially the sealing surfaces, removing any debris or old gasket material.
8. Install the new bearings and lip seal into the housing, ensuring they are seated correctly. Install the new retaining rings.
9. Lightly lubricate the new impeller with water-based lubricant and insert it into the housing with a twisting motion, following the direction of engine rotation.
10. Install the new key, cam, and cam hardware if required.
11. Place the new gasket or O-ring on the pump body and reinstall the cover plate, tightening the screws evenly in a star pattern.
12. Reconnect the hoses, open the seacock, start the engine, and check thoroughly for leaks.

Troubleshooting & FAQ

How do I confirm this kit fits my engine's pump?
This kit is designed for Sherwood pump models P102, P105, P109, and P110. Please be aware that Sherwood P102 and P105 pumps manufactured before 1993 may require a different gasket due to a different end cover size. Always verify your specific pump model number and check our compatibility tables before purchasing.

What are the signs that my impeller needs to be replaced?
The most common signs of a failing impeller are the engine running hotter than normal, a noticeable reduction in water flow from the exhaust outlet, or visible damage like cracks, tears, or stiff/brittle blades on the impeller itself during a visual inspection.

How often should I replace my water pump impeller?
For preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years. The replacement interval can vary based on engine hours, operating conditions (sandy vs. clear water), and storage procedures during the off-season.
