Troubleshooting & FAQ
How do I confirm this kit fits my specific engine?
Verify your engine's model (DT115 or DT140) and year (1986–2001) against the compatibility table. You can also cross-reference your existing part number with those listed in the Part Number Matrix.
What are the signs of a failing water pump?
Common symptoms include the engine overheating at idle or low speeds, a weak or intermittent stream from the "telltale" water outlet, or a melted water pump housing upon inspection.
How often should the water pump impeller be replaced?
For preventative maintenance, it is recommended to replace the impeller and gaskets every 1 to 2 years or every 100-200 hours of use, whichever comes first. This interval can vary based on operating conditions (e.g., saltwater vs. freshwater).
Why does the kit include a key with multiple part numbers?
The different key part numbers (09420-05009, 09420-05006, 09420-05005) are functionally identical and have been used interchangeably by the manufacturer over the production years. The included key will fit the specified engine models.
