Installation Notes

Ensure the engine is off and disconnect the battery terminals for safety.
Remove the lower unit (gearcase) from the outboard motor. Refer to your service manual for specific instructions.
Unbolt and remove the existing water pump housing to access the old impeller and gaskets.
Carefully clean all mating surfaces, removing any old gasket material or corrosion.
Install the new gaskets, wear plate, and impeller. Ensure the impeller key is correctly seated.
Lightly lubricate the inside of the pump housing and the new impeller with a marine-grade grease.
Reassemble the water pump housing, ensuring bolts are tightened to the manufacturer's specified torque.
Reinstall the lower unit, reconnect the battery, and test the engine's cooling system at idle, confirming water flows from the tell-tale port.

Troubleshooting & FAQ

What are the signs of a failing water pump?

Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or a noticeable decrease in engine performance. A worn or damaged impeller is the most frequent cause.

How often should the water pump impeller be replaced?

For most outboards, it's recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use, whichever comes first. This interval can be shorter if you operate in sandy or silty water.

What is the difference between the 17400-89812 and 17400-99J20 kits?

The 17400-89812 is a comprehensive maintenance kit that includes the water pump repair components plus spark plugs, filters, anodes, and various gaskets for a full service. The 17400-99J20 is a basic water pump repair kit containing only the core components for the pump itself (impeller, plate, sleeve, gasket, key).

My engine still overheats after installation. What should I check?

Verify that the impeller was installed with the vanes rotating in the correct direction and that the woodruff key is properly seated. Check for any blockages in the cooling water passages, intake screens, and the tell-tale outlet. Ensure all gaskets are correctly sealed.

Will this kit fit a Suzuki DF9.9A model?

No, the complete 17400-89812 maintenance kit is specifically for DF9.9B, DF15A, and DF20A models from 2013 onwards. For the DF9.9A (and DF8A), the compatible basic water pump repair kit is 17400-99J20.
