Installation Guide

1. Safety First: Disconnect the battery and close the water inlet seacock.
2. Drain System: Drain the raw water system to prevent spillage. Place rags under the pump to catch any residual water.
3. Remove Hoses: Loosen the hose clamps and carefully detach the inlet and outlet hoses from the pump.
4. Remove Pump Cover: Unscrew the bolts holding the raw water pump cover and remove it.
5. Extract Old Impeller: Use impeller pullers or two flat-head screwdrivers to carefully pry out the old impeller.
6. Remove Seals & Bearings: Remove the retaining ring, then press out the old bearing and seal from the pump housing. Note their orientation.
7. Clean Housing: Thoroughly clean the pump housing, removing any debris, salt deposits, or old gasket material.
8. Install New Components: Press the new seal and bearing into the housing, using the retaining compound on the bearing. Install the new retaining ring.
9. Install New Impeller: Lightly lubricate the new impeller and housing interior with a suitable marine lubricant. Insert the new impeller with a rotational motion to bend the vanes correctly.
10. Reassemble: Install the new O-ring on the pump cover, then reattach the cover with the new stainless steel screws.
11. Reconnect & Test: Reattach the water hoses and tighten the clamps. Open the seacock and reconnect the battery.
12. Check for Leaks: Start the engine and immediately check the pump and hose connections for any leaks. Ensure water is flowing properly.
