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.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
