Troubleshooting & FAQ

How do I confirm this kit fits my engine?

The best way to ensure fitment is to check your engine's model and year against the "Compatible Engine Models" table above. You can also verify your existing part number matches the ones listed in the "Part Number Cross-Reference" section. Using the Suzuki parts diagrams linked above can also help you visually confirm the required parts.

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

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

How often should I replace my water pump impeller?

For most outboards, it is recommended to inspect the impeller annually and replace it every 2-3 years or every 200-300 hours of use, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater environments.

What are the signs of a failing water pump?

Common symptoms include a weak or intermittent water stream from the "tell-tale" port, engine overheating alarms, or a noticeable decrease in engine performance. A worn or damaged impeller is the most common cause of these issues.
