Installation Guide
-
Safety First: Disconnect the battery and spark plug wires before starting.
-
Access the Lower Unit: Drain the gearcase oil. Unbolt and carefully remove the lower unit (gearcase) from the outboard's driveshaft housing.
-
Remove the Old Pump: Unscrew the bolts holding the water pump housing cover. Slide the housing up to expose the old impeller.
-
Inspect and Remove Components: Take note of the order of all components. Remove the old impeller, key, wear plate, and gasket. Clean all surfaces thoroughly.
-
Install New Components: Place the new gasket and wear plate onto the driveshaft. Slide the new key into its slot on the driveshaft.
-
Install New Impeller: Coat the new impeller with a light layer of marine grease. Slide it onto the driveshaft, twisting it clockwise to bend the vanes correctly as it enters the housing.
-
Reassemble the Pump: Reinstall the water pump housing and tighten the bolts to the manufacturer's specified torque.
-
Reattach Lower Unit: Reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube align correctly. Refill the gearcase with fresh oil.
-
Test the System: Reconnect the battery and spark plugs. Start the engine in water and check for a strong, steady stream from the tell-tale outlet.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my exact Suzuki model?
A: The best way is to check the Compatible Engine Models table on this page. Verify your engine's model, horsepower, and year range. You can also compare the part numbers listed in the Part Number Cross-Reference table with your old parts or service manual.
Q: What are the common signs of a failing water pump impeller?
A: The most common signs are a weak or non-existent water stream from the engine's tell-tale outlet, and your engine overheating or displaying an overheat alarm. Reduced cooling efficiency can cause serious engine damage.
Q: How often should I replace my outboard's impeller?
A: As a general rule, it's recommended to replace the impeller every 1 to 2 years or every 100-200 hours of use, whichever comes first. However, if you frequently operate in sandy or silty water, more frequent inspections and replacements are advised.
