Installation Notes

  1. Disconnect the negative battery cable before starting work.
  2. Place a drain pan under the lower unit and remove the gear lube drain/fill screws to empty the oil.
  3. Remove the bolts securing the lower unit (gearcase) to the engine's upper casing and carefully lower it.
  4. Locate the water pump housing on top of the gearcase and remove its bolts.
  5. Slide the housing up and off the driveshaft to expose the old impeller. Note the rotational direction of the existing impeller's blades.
  6. Remove the old impeller, woodruff key, and any gaskets. Clean all surfaces thoroughly.
  7. Install the new woodruff key and apply a light coat of marine grease or soap/water solution to the new impeller and inside the pump housing.
  8. Slide the new impeller onto the driveshaft, turning the shaft clockwise to help fold the blades in the correct direction.
  9. Reinstall the water pump housing with new gaskets and torque bolts to manufacturer specifications.
  10. Reattach the lower unit to the engine, ensuring the driveshaft and shift shaft align correctly.
  11. Refill the lower unit with the specified amount of fresh gear lube.
  12. Once the boat is in water, start the engine and verify a steady stream of water is exiting the tell-tale port.

Troubleshooting & FAQ

How do I know if this impeller fits my Yamaha engine?

This impeller is engineered for a wide range of Yamaha 60HP to 90HP outboard models made between 1984 and 2009. To ensure a perfect match, please consult the detailed "Engine & Model Compatibility" table on this page and verify your specific model and year before ordering.

What are the signs of a bad water pump impeller?

The most common symptoms of a failing impeller are a weak or inconsistent water stream from the engine's tell-tale port, frequent engine overheating alarms, and a noticeable reduction in overall engine performance. A worn impeller cannot effectively cool the engine.

How often should I replace my outboard's impeller?

As a key part of preventative maintenance, we recommend replacing the impeller every 100-200 hours of operation or every 1-2 years, whichever comes first. More frequent replacement may be necessary if you operate in sandy, silty, or saltwater conditions.

Is this impeller made from the same material as OEM?

Yes, this aftermarket impeller is made from a high-quality, durable neoprene and rubber compound designed to meet or exceed OEM specifications for longevity and performance in marine environments.

My old impeller's blades are bent. Is that normal?

Yes, it's normal for the blades to have a set curve after being housed inside the pump cup. When installing the new one, you'll need to turn the driveshaft in its normal direction of rotation (usually clockwise) to fold the blades correctly as you slide the housing down over them.

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?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.

Safety & Important Info

  • Verify images/specifications vs your original part. If anything differs—even if your model appears compatible—do not purchase.
