Troubleshooting & FAQ

How do I confirm this kit fits my specific engine?

The most reliable method is to match your engine's model, year, and (if applicable) serial number against the compatibility tables above. For Suzuki DF90-DF140 models, verifying the serial number is critical, as this kit only fits earlier production engines. Do not rely on appearance alone.

What are the signs of a failing water pump impeller?

Common symptoms include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, or finding cracked, brittle, or worn-down blades on the old impeller during inspection.

How often should I replace my outboard's impeller?

As a preventative maintenance measure, it is highly recommended to replace the impeller every 1 to 2 years or every 100 to 200 hours of operation, whichever comes first. Usage in saltwater or silty/sandy conditions may require more frequent replacement.

Is this a direct replacement for Suzuki part 17400-92J00?

Yes, this is an aftermarket kit designed to be a direct replacement for Suzuki OEM part number 17400-92J00, as well as several other part numbers from Suzuki, Johnson/Evinrude, and Sierra listed in our Part Number Matrix.

What is included in this water pump kit?

The package contains all the necessary components for a standard water pump service: a new impeller, pump housing, base plate/panel, a full gasket set, and the required installation hardware (screws and washers).
