Installation Guide

1. Disconnect the fuel line and remove the lower unit from the outboard motor following your engine's service manual procedures.
2. Locate and remove the water pump housing cover, typically secured by bolts or screws.
3. Carefully extract the old impeller from the pump housing, noting the direction of the blade curve.
4. Inspect the impeller housing and plate for wear, corrosion, or damage; clean all surfaces thoroughly.
5. Lubricate the new impeller blades with glycerin, soapy water, or water pump grease—never petroleum-based lubricants.
6. Insert the drive key/pin into the impeller shaft slot, ensuring it is fully seated.
7. Install the new impeller into the housing with blades oriented in the correct rotation direction (typically clockwise when viewed from above).
8. Reassemble the water pump housing cover, ensuring all gaskets and seals are properly positioned.
9. Reinstall the lower unit onto the outboard motor, tightening mounting bolts to manufacturer specifications.
10. Reconnect the fuel line and run the engine in a test tank or on-the-water, checking for proper water discharge from the telltale outlet.

Troubleshooting & FAQ

Q: How do I confirm this impeller fits my Suzuki engine?
A: Cross-reference your engine model and year with the compatibility table above. The DT9.9 (1980–87), DT14 (1977–80), DT16 (1977–82), DT25 (1977–82), and DT28 (1972–82) are all compatible. You can also verify using Suzuki exploded diagrams linked in the Compatible Engine Models section.

Q: How often should I replace my 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 that my impeller is failing?
A: Common symptoms include weak or no water stream from the telltale/pilot hole, engine overheating, steam from the engine, or reduced cooling performance. If you notice any of these, inspect the impeller immediately.

Q: Can I use petroleum-based grease to install the impeller?
A: No, never use petroleum-based lubricants as they can degrade the rubber. Use only glycerin, soapy water, or water pump-specific grease during installation.

Q: Is the drive key/pin included with this kit?
A: Yes, this package includes the rubber impeller with the drive key/pin for complete installation.
