Installation Guide

1. Ensure the engine is off and cool, and close the raw water intake seacock.
2. Place a rag or container under the pump to catch any spilled water.
3. Remove the screws from the water pump's cover plate.
4. Carefully pry the cover off. If it's stuck, gently tap the side with a soft mallet.
5. Use needle-nose pliers or an impeller puller to grip the hub of the old impeller and pull it straight out. Note the direction the blades are bent.
6. Clean the interior of the pump housing and inspect for scoring or debris. Remove the old gasket or O-ring and clean the sealing surfaces.
7. Lubricate the inside of the housing and the new impeller with a water-based lubricant or dish soap.
8. Install the new impeller with a twisting motion, ensuring the blades are bent in the same direction as the old one.
9. Place the new gasket or O-ring onto the cover plate.
10. Reinstall the cover plate and tighten the screws evenly in a star pattern to ensure a proper seal. Do not overtighten.
11. Open the raw water seacock.
12. Start the engine and immediately check the pump for leaks and verify that water is flowing from the exhaust.
