Troubleshooting & FAQ

Q: How do I confirm this impeller fits my Suzuki engine?
A: Verify that your engine is a 2-stroke DT9.9 or DT16 model manufactured between 1980 and 1982. Cross-check your original impeller against OEM part number 17461-93500. If specifications match, this impeller will fit.

Q: How often should I replace the water pump impeller?
A: Most manufacturers recommend replacing the impeller every 2–3 years or 200–300 hours of operation, whichever comes first. If you frequently operate in sandy or debris-laden water, inspect and replace more often.

Q: What are the signs of a failing impeller?
A: Common symptoms include reduced or no water flow from the telltale port, engine overheating, steam from the cowling, or loss of power. Inspect the impeller immediately if you notice any of these issues.

Q: Can I use petroleum-based grease to lubricate the impeller during installation?
A: No, petroleum-based products will damage the rubber vanes. Use only glycerin, soapy water, or manufacturer-approved impeller lubricant.
