Installation Notes
- Disconnect the battery and remove the engine cover.
- Shift the outboard into neutral and remove the lower unit mounting bolts.
- Carefully lower and separate the gearcase from the driveshaft housing. Be mindful of the shift shaft linkage.
- Locate the water pump housing, typically situated on top of the gearcase.
- Unbolt and remove the water pump housing cover to expose the old impeller.
- Note the rotational direction of the old impeller fins before removing it. Pull the old impeller off the driveshaft.
- Clean the housing interior and inspect the wear plate and housing for scoring or damage. Replace if necessary.
- Lightly lubricate the new impeller and the inside of the housing with a marine-safe grease or soapy water.
- Slide the new impeller onto the driveshaft, rotating it in the correct direction to fold the vanes properly.
- Reinstall the water pump housing and torque the bolts to manufacturer specifications.
- Reassemble the lower unit to the upper housing, ensuring all shafts and tubes align correctly.
- Once assembled, test the engine in water using flush muffs to confirm water is pumping correctly from the tell-tale port.
Troubleshooting & FAQ
How do I know if my water pump impeller has failed?
The most common sign of a failing impeller is a weak or non-existent stream of water from the engine's tell-tale (or "pee") hole. Other symptoms include the engine overheating alarm sounding or steam coming from the exhaust.
How often should I replace my impeller?
As a general maintenance guideline, it is recommended to inspect your water pump impeller annually and replace it every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval can shorten in saltwater or silty/sandy conditions.
What is the difference between Suzuki OEM numbers like 17461-93901 and 17461-93902?
These different part numbers typically represent minor revisions, material updates, or supersessions made by the manufacturer over time. This aftermarket impeller is designed to replace all listed variations (93900, 93901, 93902, 93903, 939M0, 939L0).
Is this impeller difficult to install?
Installation requires basic mechanical skills and tools to drop the lower unit (gearcase) of your outboard. While it is manageable for many DIY mechanics, we recommend professional installation if you are not comfortable with the process to ensure safety and correct function. See the installation notes above for a general guide.
Will this fit my Johnson/Evinrude even though it's listed for Suzuki?
Yes. During a specific period (2002-2006), some Johnson/Evinrude 4-stroke outboards used Suzuki powerheads. This impeller is the correct cross-reference for the specified Johnson/Evinrude models and years, replacing OEM part 5033112.
What causes premature impeller failure?
The most common causes are running the engine dry (even for a few seconds), operating in sandy or debris-heavy water, and age. The rubber becomes brittle over time and can crack or lose its flexibility, reducing pumping efficiency.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
Shipping speed & cost?
