Troubleshooting & FAQ

How do I know if this kit is for my engine?

This kit is specifically designed for Suzuki DF25A and DF30A 4-Stroke outboards from 2014 to 2023. Please verify your exact model and year using the compatibility table provided on this page.

What are the signs of a failing water pump impeller?

Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, and reduced engine performance. A worn impeller cannot effectively pump cooling water, leading to overheating.

How often should I replace my water pump impeller?

As a general maintenance guideline, the impeller should be inspected annually and replaced every 1-2 years or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater, sandy/silty water).

What is the difference between part number 17400-94L00 and 17400-94L21?

Part number 17400-94L21 is the direct supersession for 17400-94L00 and other previous versions. It represents the latest revision from the manufacturer, and this kit is compatible with all of them.

Is the O-ring (09280-54004) included?

Yes, our kit includes the O-ring as shown in the "What's in the Box" section. While some other kits on the market may omit it, we include all necessary components for a standard service.

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.
