Installation Guide
- Safety First: Disconnect the battery and shift the outboard into neutral. Place the lower unit in a suitable stand or on a workbench.
- Access the Pump: Remove the bolts securing the lower unit (gearcase). Carefully separate it from the upper engine housing.
- Disassemble Housing: Unscrew the bolts on the water pump housing. Lift the housing to expose the impeller.
- Remove Old Components: Take out the old impeller, wear plate, gaskets, and key. Note the orientation of the impeller vanes.
- Clean Surfaces: Thoroughly clean the driveshaft and all mating surfaces where gaskets and plates will sit. Remove any old sealant or corrosion.
- Install New Parts: Place the new pump plate gasket and plate over the driveshaft. Slide the new key into the driveshaft slot.
- Install Impeller: Lubricate the new impeller with a bit of soapy water or marine grease. Slide it onto the shaft while turning the shaft clockwise to bend the vanes correctly.
- Reassemble Housing: Install the new pump case sleeve and reinstall the housing. Securely tighten the bolts to the manufacturer-specified torque.
- Reattach Lower Unit: Guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align. Bolt it securely.
- Test Operation: Reconnect the battery. Start the engine in a test tank or with a water flusher, and verify a strong, consistent stream of water from the tell-tale outlet.
Troubleshooting & FAQ
How do I confirm this fits my Suzuki engine?
Check the "Compatible Engine Models" table on this page. Match your Suzuki engine model (e.g., DF9.9B), rated horsepower, and year range to ensure a correct fit. Comparing the part numbers listed to your engine's service manual is also a reliable method.
What are the signs my water pump impeller needs replacing?
A weak, inconsistent, or completely absent water stream from the engine's tell-tale outlet is the most common sign. An engine overheating alarm or abnormally high temperature reading also indicates a potential cooling system issue, often linked to a failed impeller.
How often should the impeller be replaced?
As a preventative maintenance measure, it is recommended to inspect the impeller annually and replace it every 1-3 years. If you frequently operate in sandy, silty, or saltwater environments, more frequent replacement (every year) is advised to prevent unexpected failure.
My original part number is 17400-99841. Will this kit work?
Yes. This kit is the current, updated replacement for older versions, including 17400-99841 and 17400-99840. The "Part Number Cross-Reference" table confirms this supersession.
