Package Contents
Installation Guide
-
Disconnect the engine: Turn off the fuel supply and disconnect the battery to ensure safety during the procedure.
-
Access the water pump housing: Remove the lower unit from the outboard motor according to your service manual. This typically involves disconnecting the shift linkage and removing mounting bolts.
-
Remove the water pump cover: Unbolt and carefully lift off the pump housing cover to expose the old impeller.
-
Extract the old impeller: Use needle-nose pliers or a specialized impeller puller to gently remove the worn impeller from the pump housing. Inspect for damaged or missing vanes.
-
Clean the pump chamber: Thoroughly clean the pump housing, cover, and base plate to remove old gasket material, debris, and corrosion.
-
Lubricate the new impeller: Apply a liberal amount of glycerin-based or waterproof grease to all impeller vanes and the inside of the pump housing to ease installation and prevent dry-start damage.
-
Install the new impeller: Align the impeller keyway with the drive pin and gently press it into the housing, ensuring all vanes fold in the correct direction. Rotate the driveshaft clockwise to confirm smooth engagement.
-
Replace gaskets and seals: Install new pump housing gaskets and O-rings as needed to ensure a watertight seal.
-
Reassemble the water pump cover: Position the cover plate and secure it with the original bolts, tightening to manufacturer-recommended torque specifications.
-
Reattach the lower unit: Carefully align the shift linkage and reinstall the lower unit onto the engine block, torquing all fasteners properly.
-
Test the system: Reconnect the battery and run the engine in a test tank or on a flushing attachment. Verify strong water flow from the tell-tale indicator.
-
Final inspection: Check for leaks around the pump housing and ensure the engine maintains proper operating temperature during a short test run.
Troubleshooting & FAQ
Q: How do I confirm this impeller fits my Suzuki engine?
A: Cross-reference your engine model and year against the compatibility table above. You can also verify the OEM part number 17461-93004 in your Suzuki service manual or parts diagram to ensure a match.
Q: How often should I replace the water pump impeller?
A: Most manufacturers recommend replacing the impeller every 2–3 years or 200–300 operating hours, whichever comes first. If you operate in sandy or debris-filled water, inspect and replace it more frequently.
Q: What are the signs of a failing impeller?
A: Common symptoms include weak or no water discharge from the tell-tale, engine overheating, steam from the motor, or debris in the cooling system. If you notice any of these, inspect and replace the impeller immediately.
Q: Can I install this impeller myself, or do I need a mechanic?
A: Installation is straightforward for those with basic mechanical skills and tools. However, proper alignment, lubrication, and torque specifications are critical, so professional installation is recommended if you're unsure.
