- Remove the water-pump housing cover to access the impeller.
- Record the existing impeller-vane direction, then remove the old impeller, gaskets, wear plate and key.
- Clean the mating surfaces and remove old gasket material and debris.
- Install the replacement wear plate and the appropriate gasket.
- Install the shaft key securely in the driveshaft keyway.
- Fit the replacement impeller over the shaft and position the vanes in the direction required by the engine’s normal shaft rotation.
- Reinstall the pump housing cover with the replacement gasket and tighten the fasteners according to the manufacturer’s service specifications.
- Reinstall the lower unit, ensuring that the driveshaft, shift shaft and water tube engage correctly.

Troubleshooting & FAQ
How do I confirm this kit fits my engine?
Check that your outboard is a Suzuki DF8A or DF9.9A 4-stroke model from 2010 or later and compare the original water-pump assembly with the kit contents. Also compare the original reference number, including 17400-99J01 where applicable.
What are the signs of a failing water-pump impeller?
Common signs include an overheating warning, a weak or intermittent tell-tale stream, reduced cooling-water flow or steam near the exhaust. A removed impeller may show cracked, hardened, damaged or missing vanes.
How often should the impeller be replaced?
Replacement timing depends on engine use, storage and water conditions. Inspect the impeller during scheduled maintenance and replace it when the vanes show wear, deformation or damage. More frequent inspection may be appropriate in saltwater, sandy or silty conditions.
Is there a correct orientation for the impeller vanes?
Yes. The vanes must be positioned to follow the water pump’s normal shaft rotation when the impeller is installed in the housing. Follow the engine manufacturer’s service procedure for the correct rotation and assembly method.
Is this an OEM part?
No. This is an aftermarket replacement service kit intended for the listed Suzuki applications. It is not manufactured or supplied by Suzuki.
What should I do if my original parts look different?
Do not force installation or mix incompatible pump components. Compare the model designation, original part references and kit contents, and consult the engine service information before proceeding.
