Troubleshooting & FAQ
How do I know if this kit fits my Suzuki outboard?
This kit fits Suzuki DF9.9 (2007–2013) and DF15 (2007–2015) 4-stroke models. The most reliable method is to confirm your engine's original part number matches the primary replacement number, 17400-94J00. Always check the compatibility table and verify against your existing part.
What are the signs of a failing water pump impeller?
Common symptoms include a weak, intermittent, or non-existent water stream from the "telltale" outlet, engine overheating alarms, and a noticeable reduction in engine performance. A damaged impeller cannot effectively cool the engine.
How often should I replace my water pump impeller?
As a best practice for preventative maintenance, you should inspect your impeller annually and plan to replace it every 1-2 years or after every 100-200 hours of operation. Service intervals may be shorter if you frequently operate in sandy, silty, or saltwater conditions.
Can I install this kit myself?
While installation can be performed with standard mechanic's tools, it requires careful disassembly and reassembly of the lower unit. We recommend professional installation if you are not familiar with the procedure to ensure safety and correct function.
Is this a genuine Suzuki part (OEM)?
This is an aftermarket replacement part, not an OEM component. It has been built to OEM-level specifications with comparable materials and manufactured in an ISO 9002 facility with batch inspections for quality assurance.
What are your shipping speed and cost?
We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free to most regions; expedited options will appear at checkout if they are available for your location.
