For Suzuki Owners: This impeller fits a range of 2-stroke and 4-stroke models. Note the two OEM part numbers (17461-93903 and 17461-93904); the primary difference is the inclusion of an impeller key with the latter. We recommend checking the dimensions of your original impeller to ensure a perfect match.
For Johnson/BRP Owners: Fitment is for specific 2000+ models equipped with Suzuki-built powerheads. Verifying your engine's origin and original part number is critical.

Installation Notes
- Disconnect the spark plug wires and secure the propeller to prevent accidental starting.
- Place a drain pan under the gearcase and remove the gearcase oil drain screw to empty the lower unit oil.
- Remove the bolts connecting the lower unit (gearcase) to the upper leg of the outboard.
- Carefully lower the gearcase away from the engine. The driveshaft will disengage from the powerhead.
- Unbolt and remove the water pump housing to expose the old impeller. Note the orientation of the old impeller's blades.
- Clean any debris or corrosion from the housing and wear plate. Apply a light coat of marine grease to the interior.
- Slide the new impeller onto the driveshaft, ensuring the key way aligns. Turn the driveshaft clockwise to seat the blades in the correct direction.
- Reinstall the water pump housing, ensuring a proper seal. Torque bolts to manufacturer specifications.
- Reassemble the lower unit to the engine, refilling with fresh gearcase oil. Reconnect spark plug wires.
- Test the engine in a suitable water source, verifying a steady stream of water from the tell-tale outlet.
Troubleshooting & FAQ
What is the difference between part 17461-93903 and 17461-93904?
The primary difference noted by our sources is that the 17461-93904 version includes the impeller key, while the 17461-93903 version does not. The impeller itself is dimensionally the same, but it's crucial to confirm if you need a new key for your installation.
Why do I need to check dimensions if my model is listed?
Over an engine's production run, manufacturers sometimes make minor mid-year changes. Because several variations of this impeller exist, comparing the dimensions (especially height and diameter) of your old part against the new one is the best way to guarantee a perfect fit and avoid cooling issues.
What are the signs of a failing water pump impeller?
Common signs include a weak or intermittent water stream from the "tell-tale" outlet, engine overheating alarms, and in severe cases, steam from the exhaust. Reduced engine performance can also occur as the ECU limits RPM to prevent damage.
How often should I replace my impeller?
For preventative maintenance, it is recommended to inspect and likely replace the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval may be shorter if you operate in sandy, silty, or saltwater conditions.
How do I know if my Johnson engine has a Suzuki powerhead?
Around the year 2000, some four-stroke Johnson and Evinrude outboards were re-branded Suzuki engines. Check for a model number plate on the engine bracket; a model number like "J15R4S" where "4S" indicates a four-stroke, often of Suzuki origin. Comparing your existing parts to Suzuki equivalents is the most reliable method.
