Installation Guide

1. Disconnect Power: Disconnect the engine's battery before starting work.
2. Remove Lower Unit: Unbolt and carefully slide the lower unit (gearcase) off the outboard's driveshaft housing.
3. Access Pump: Locate and unbolt the water pump housing, which sits on top of the lower unit.
4. Inspect & Remove Old Parts: Remove the old housing cover, impeller, wear plate, and gaskets. Note the rotational direction of the old impeller vanes.
5. Clean Surfaces: Thoroughly clean the mating surfaces where the new gaskets and plate will sit, removing any old sealant or corrosion.
6. Install New Components: Install the new wear plate and gasket. Slide the new impeller onto the driveshaft, turning the shaft in its normal rotational direction to bend the vanes correctly.
7. Reassemble Pump: Place the new gaskets and reinstall the water pump housing, ensuring a secure seal. Tighten bolts to the manufacturer's specified torque.
8. Reinstall Lower Unit: Carefully guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align correctly. Fasten the bolts securely.
9. Test Operation: Reconnect the battery. With the outboard in a barrel of water or attached to a "muffs" style flush attachment, start the engine and confirm a steady stream of water from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Suzuki engine?

A: Check your engine's model (DF60, DF70, DT90, or DT100) and year (1998-2007). You can also cross-reference your existing part number with the numbers listed in the "Part Number Cross-Reference" table, such as Suzuki 17400-87E03 or 17400-87E04.
