What’s in the Box

  • 1 x Water pump impeller

Impeller key and gaskets are not confirmed as included with this single-impeller listing. Reuse only serviceable original components or obtain any required key, gasket, or seal separately according to your engine service manual.

Installation Notes

Impeller replacement requires access to the water-pump housing and may require removal of the lower unit. Follow the service manual for your exact engine model and observe all manufacturer safety procedures.

  1. Stop the engine, remove the ignition key, and disconnect the battery according to the manufacturer's safety procedure.
  2. Place the outboard in a stable service position and remove the lower unit if required by the engine design.
  3. Remove the water-pump housing cover and retain the fasteners in their original locations.
  4. Remove the old impeller and inspect the drive key, pump housing, wear plate, seals, and gasket surfaces.
  5. Clean the pump cavity and replace worn or damaged related components before installing the new impeller.
  6. Install the impeller using the correct drive key and orient the blades in the normal direction of rotation specified by the service manual.
  7. Reassemble the water-pump housing with the correct gasket or seal for your engine application.
  8. Reinstall the lower unit, reconnect any removed linkage or water tube connections, and tighten fasteners to the service-manual specifications.
  9. Run the engine only with an appropriate cooling-water supply. Confirm a strong telltale stream and monitor for overheating.

Troubleshooting & FAQ

How do I confirm that this impeller fits my outboard?

Compare your original part number with the references listed above, then verify the complete engine model, horsepower, stroke, year, and serial-number conditions in the service or parts manual. Do not rely on horsepower alone.

What are the signs of a worn water-pump impeller?

Possible symptoms include a weak or missing telltale stream, overheating warnings, reduced cooling performance, cracked or brittle blades, or visible blade deformation. Inspect the pump housing and related components whenever the impeller is replaced.

Is the impeller key included?

No key is confirmed as included with this single-impeller listing. Check the existing key for wear and replace it if required by the service manual.

Does this listing include a complete water-pump kit?

No. The company product record identifies this item as a single water pump impeller, not a kit. Gaskets, keys, housing parts, and other service components are not confirmed as included.

Is this an OEM Honda or Tohatsu part?

No. This is an aftermarket replacement impeller. Honda and Tohatsu numbers shown on this page are reference numbers used to identify compatible applications.

Can I install the impeller myself?

Installation may be possible for an experienced technician, but it can involve lower-unit removal and water-pump disassembly. Use the correct service manual or obtain professional installation if you are not familiar with outboard lower-unit service.

Safety & Important Information

  • Verify the exact part number, model, stroke, year, and serial-number application before purchase.
  • Do not operate the outboard without an adequate cooling-water supply.
  • Replace damaged gaskets, keys, seals, wear plates, or pump housings as required by the service manual.
  • This is an aftermarket replacement, not an OEM component.
  • Professional installation is recommended when lower-unit service experience is limited.
