Troubleshooting & FAQ

Q: How do I confirm this kit fits my Suzuki engine?

A: Check your engine's model and year against the "Compatible Engine Models" table. This kit fits DF250SS (2008+), DF250AP (2013+), DF300 (2007-2011), and DF300AP (2012+). You can also cross-reference your existing part number with the numbers listed, such as 17400-98J04.

Q: What are the signs of a failing water pump impeller?

A: Common signs include the engine overheating, a weak or inconsistent water stream from the "telltale" outlet, or a high-temperature alarm. An impeller can become brittle, cracked, or worn over time, which reduces its ability to pump cooling water effectively.

Q: How often should I replace the water pump impeller?

A: As part of preventative maintenance, it is recommended to inspect and/or replace the impeller every 100-200 operating hours or at least once per boating season. Replacement may be needed sooner if you frequently operate in sandy, silty, or debris-heavy water.
