Troubleshooting & FAQ

How do I confirm this kit fits my Suzuki engine?
This kit is specifically designed for Suzuki models DF60, DF70, DT90, and DT100 from 1998 through 2007. The surest way to confirm fitment is to verify that your existing part number matches our stated cross-references: 17400-87E04, 17400-87E03, or Sierra 18-3254.

What are the signs of a failing water pump impeller?
Key signs include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "telltale" outlet, or finding the old impeller's rubber vanes are cracked, brittle, or have taken a permanent set.

How often should I replace the water pump impeller?
As a critical part of preventative maintenance, you should inspect the impeller annually and plan to replace it every 1-2 years or every 100-200 hours of use. More frequent replacement is recommended for boats operating in saltwater or debris-heavy water.
