Installation Notes

Generic installation steps are provided below. For detailed instructions specific to your model, consult your owner's manual or a professional marine mechanic.

Disconnect the battery and remove the engine cover.
Shift the outboard into neutral.
Drain the lower unit gear lube.
Remove the bolts securing the lower unit (gearcase) to the engine's upper section.
Carefully lower and separate the gearcase from the drive shaft housing.
Locate and unbolt the water pump housing, typically found on top of the gearcase.
Remove the old impeller, noting the rotational direction of the vanes.
Clean the housing and install the new impeller, ensuring the vanes are oriented correctly.
Reassemble the water pump housing with new gaskets if necessary.
Reattach the lower unit to the engine, ensuring all shafts and tubes align correctly.
Refill the gear lube, reconnect the battery, and test the engine in water to verify a strong stream from the tell-tale outlet.

Troubleshooting & FAQ

How do I confirm this impeller fits my Suzuki outboard?

The best way is to match your existing part number to one of the cross-references listed (e.g., 17461-93901). If you don't know your part number, check the Engine & Model Compatibility table to see if your outboard model and horsepower are listed.

What are the signs of a failing water pump impeller?

Common symptoms include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alerts, or a noticeable drop in performance. If you see these signs, inspect your cooling system immediately.

How often should I replace my outboard's impeller?

As a general maintenance guideline, it's recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use, whichever comes first. This interval can change based on operating conditions (e.g., saltwater vs. freshwater).

Can I install this impeller myself?

If you have general mechanical experience and the correct tools, replacement is possible. However, it requires lowering the gearcase, which can be complex. For safety and to ensure correct installation, we recommend a professional marine mechanic perform the service.
