Troubleshooting & FAQ
What symptoms indicate a worn water-pump impeller?
A weak or missing tell-tale stream, overheating, an overheating warning, or visible cracks, deformation, or missing blades on the old impeller can indicate that service is needed. Inspect the complete water-pump assembly before replacing only the impeller.
Will this fit an engine that is not listed?
Do not assume compatibility from horsepower alone. Use this part only when your Mercury or Mariner model and serial-number range match the compatibility information above and the replacement impeller matches the original part.
Does this kit include the wear plate?
No. The company product description identifies this configuration as a water pump impeller kit without the wear plate. Inspect your existing wear plate and replace it separately if it is worn or damaged.
Is this an OEM part?
No. This is an aftermarket replacement. The listed Mercury numbers are manufacturer reference numbers used to help identify the correct application.
Does this product fit Tohatsu, Nissan, or Johnson/Evinrude engines?
This product page is for the Mercury/Mariner application and serial ranges listed above. Do not use the Tohatsu, Nissan, or Johnson/Evinrude references from other impeller products to establish fitment for this item.
Safety & Important Information
- Confirm the exact engine model and serial number before ordering.
- Compare the replacement impeller with the original part before installation.
- Do not operate an outboard with inadequate cooling-water flow.
- Follow the manufacturer’s service-manual procedures and torque specifications.
- Professional installation is recommended if you are not familiar with outboard lower-unit or water-pump service.
