Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is securely mounted.
2. Access the Lower Unit: Remove the bolts securing the lower unit (gearcase) to the engine leg and carefully lower it.
3. Remove Pump Housing: Locate and unbolt the water pump housing to reveal the impeller.
4. Inspect and Remove Old Parts: Take out the old impeller, gasket, and wear plate. Note the orientation of the impeller vanes.
5. Clean Surfaces: Thoroughly clean the inside of the housing and all mating surfaces, removing any old gasket material or debris.
6. Install New Components: Place the new gasket and wear plate into position.
7. Install Impeller: Apply a light coat of marine grease or soap-and-water solution to the housing interior. Slide the new impeller key onto the driveshaft and install the new impeller, turning the driveshaft clockwise to bend the vanes correctly.
8. Reassemble: Reinstall the pump housing and torque the bolts to the manufacturer's specification.
9. Reattach Lower Unit: Carefully guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align correctly. Secure with bolts.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my engine?
A: The most reliable method is to cross-reference your engine's model, horsepower, and year with the information in the "Compatible Engine Models" tables above. You can also verify by matching the part number from your old components with those listed in our "Part Number Cross-Reference" section. For Suzuki owners, reviewing the exploded parts diagrams can provide final confirmation.

Q: What are the symptoms of a failing water pump impeller?
A: The most common signs are the engine running hotter than normal or overheating, and a weak, intermittent, or completely absent stream of water from the cooling system's tell-tale outlet. Upon inspection, a worn impeller may appear dry, cracked, stiff, or have broken or bent vanes.

Q: How often should I replace the water pump impeller?
A: As a general rule, it is recommended to replace your outboard's water pump impeller every 1 to 2 years, or every 100-200 hours of operation. More frequent replacement may be necessary if you operate primarily in saltwater or in water with high levels of sand or silt.
