Installation Guide

1. Shut off the engine and close the raw water intake valve (seacock).
2. Locate the raw water pump housing, typically mounted on the engine block.
3. Loosen and remove the screws on the pump cover plate.
4. Carefully pry off the cover plate and remove the old gasket. Note its orientation.
5. Use impeller pullers or two pliers to grip the hub of the old impeller and pull it straight out of the housing.
6. Clean the inside of the pump housing, ensuring it is free of any debris or old impeller blade pieces.
7. Lightly lubricate the new impeller and the inside of the housing with a water-based lubricant to ease installation.
8. Insert the new impeller by pushing it into the housing while turning it in the direction of engine rotation to bend the blades correctly.
9. Place the correct new gasket and O-ring (if applicable for your pump model) on the cover plate.
10. Re-install the cover plate and tighten the screws evenly in a star pattern to ensure a proper seal.
11. Open the raw water intake valve before starting the engine.
