What’s in the Box

This product is a water pump service kit with housing. This listing does not provide a definitive item-by-item package quantity, so compare the supplied components with the original pump assembly before installation.

Installation Notes

  2. Disconnect the battery and follow the engine manufacturer’s safety procedures.
  3. Remove the lower unit according to the service manual for your exact engine.
  4. Disassemble the existing water pump assembly and inspect the driveshaft, water tube, pump plate, and mating surfaces.
  5. Clean the mating surfaces and install the replacement housing and service components supplied for the application.
  6. Reassemble the water pump and lower unit using the manufacturer’s specified tightening sequence and torque values.
  7. Verify that the driveshaft, shift shaft, and water tube are correctly aligned before securing the lower unit.
  8. Run the engine with an appropriate flushing device and confirm a steady cooling-water telltale stream before normal operation.

Troubleshooting & FAQ

How do I know if this kit fits my engine?

Check that your Mercury or Mariner engine is a listed 4-stroke application in the 40–115 HP range, then verify the exact model and serial number against the manufacturer’s parts information. Horsepower alone is not sufficient to confirm fitment.

What are the signs of a worn water pump?

A weak or missing telltale stream, overheating warnings, or visible deterioration of the existing pump components can indicate that the water pump requires service. Diagnose the cooling system before replacing parts.

Does this product include the water pump housing?

Yes. This listing identifies it as a 4-stroke water pump service kit with housing.

Is this an OEM part?

This listing is for an aftermarket service kit. The OEM numbers shown in the reference table are compatibility and identification references, not a statement that the supplied kit is manufactured by Mercury, Mariner, or Honda.

Do the reference numbers guarantee interchangeability?

No. Reference numbers can apply to different model, year, serial-number, or configuration ranges. Confirm the complete engine application and compare the original pump assembly before ordering.

Safety & Important Info

  • Use the exact model and serial number to confirm fitment before purchase.
  • Do not rely on horsepower alone when selecting a water pump service kit.
  • Follow the manufacturer’s service manual for lower-unit removal, installation, and torque specifications.
  • Professional installation is recommended if you are not familiar with outboard lower-unit or water-pump service.
