Troubleshooting & FAQ

How do I confirm that this service kit fits my engine?

Check that your engine is one of the listed Mercury/Mariner 4-stroke 40, 50, or 60 HP configurations. Then compare the original water pump reference, including 47-19453Q2 or another number listed in the reference matrix. The exact model and shaft arrangement must match.

Does this kit include the water pump housing?

No. This is a water pump service kit without housing. The existing housing must be inspected and reused only if it is suitable according to the engine manufacturer's service requirements.

What are the signs of a worn water pump service assembly?

Possible symptoms include a weak or missing tell-tale stream, overheating warnings, or visible deterioration of the existing pump components. Inspect the complete water pump assembly before replacing parts.

Can I use the listed reference numbers without checking my model?

No. Reference numbers are provided to assist identification, but number co-occurrence does not guarantee fitment for every engine. Always confirm the complete model, horsepower, stroke, shaft arrangement, and original part number.

Is this a genuine Mercury or Mariner part?

No. This is an aftermarket replacement service kit associated with the listed Mercury/Mariner references and GLM Marine reference 12044.
