Installation Guide

1. Safety First: Disconnect the engine's battery and shift the outboard into neutral.
2. Access the Lower Unit: Place a drain pan under the gearcase and remove the drain screw to empty the gear oil.
3. Remove Gearcase: Unbolt and carefully detach the lower unit (gearcase) from the engine's upper section. You may need to disconnect the shift linkage.
4. Disassemble Pump: Remove the bolts securing the water pump housing cover. Slide the housing off the driveshaft.
5. Remove Old Impeller: Take note of the old impeller's vane orientation (clockwise or counter-clockwise). Remove the old key, impeller, plates, and gaskets.
6. Clean Surfaces: Thoroughly clean all mating surfaces, removing any old gasket material or debris.
7. Install New Components: Place the new gasket and pump plate onto the gearcase. Insert the new impeller key into the driveshaft.
8. Install New Impeller: Slide the new impeller onto the driveshaft while turning the shaft in the direction of normal engine rotation (usually clockwise) to seat the vanes correctly inside the new housing sleeve.
9. Reassemble Pump: Install the new O-rings and gaskets. Secure the water pump housing with its bolts, tightening to the manufacturer's specified torque.
10. Reinstall Gearcase: Reattach the lower unit to the engine, ensuring the driveshaft, water tube, and shift shaft align. Tighten mounting bolts to spec.
11. Refill and Test: Refill the gearcase with fresh marine gear lubricant. Reconnect the battery. Start the engine using a water supply (flusher) and check for a steady stream from the cooling system tell-tale.
