Installation Notes
- Disconnect the negative battery cable for safety.
- Place a drain pan under the lower unit and remove the gearcase oil drain/fill screw to empty the old oil.
- Remove the bolts securing the lower unit (gearcase) to the engine's midsection and carefully lower it.
- Unbolt and remove the water pump housing cover to expose the old impeller. Note the direction of the blades before removal.
- Pull the old impeller off the driveshaft, being sure to remove the drive key as well.
- Clean and inspect the pump housing, face plate, and seals for wear, scoring, or damage. Replace any worn components.
- Lightly lubricate the interior of the pump housing with marine grease.
- Slide the new drive key into its slot on the driveshaft and install the new impeller, rotating the driveshaft clockwise to help seat the blades correctly.
- Reinstall the water pump housing, tightening bolts to the manufacturer's torque specification.
- Refill the gearcase with the correct grade and amount of marine gear lube.
- Reattach the lower unit to the engine, ensuring the driveshaft, water tube, and shift shaft align properly.
- Once fully assembled, test the engine in water to confirm a steady stream of water exits the tell-tale port.
Troubleshooting & FAQ
How do I confirm this impeller fits my specific engine?
The best way is to check the Engine & Model Compatibility table on this page. Match your engine's brand, horsepower, and year. You can also cross-reference the part number stamped on your old impeller with the numbers in our Part Number Matrix.
What are the signs of a failing water pump impeller?
Common signs include a weak or nonexistent water stream from the engine's tell-tale port, an engine overheating alarm, or a noticeable decrease in engine performance. A brittle, cracked, or deformed impeller upon inspection confirms it needs replacement.
How often should I replace my outboard's impeller?
For preventative maintenance, it is recommended to inspect your impeller annually and replace it every 1-2 years, or every 100-200 hours of use, depending on operating conditions. If you frequently run in sandy, silty, or saltwater, more frequent replacement is advisable.
Can I install this myself?
Yes, replacing an impeller is a common maintenance task for those with mechanical experience and the correct tools. However, due to the importance of the cooling system, we recommend professional installation if you are not fully comfortable with the process.
What is the difference between this aftermarket part and an OEM one?
This is an aftermarket replacement, not an original equipment manufacturer (OEM) part.

How fast do you ship and what does it cost?
We ship worldwide, and typical transit time is 5–15 days for most regions. Standard shipping is free. If available for your location, expedited shipping options and their costs will be displayed at checkout.

This part is covered by a 1-year warranty against manufacturing defects under normal operating conditions. If you experience an issue, please contact our support team with your order details. Returns are accepted within our standard return window for items that are unused and in their original packaging. Please see our full policy page or contact us for instructions.
