Product Details
This aftermarket water pump repair kit is designed for selected Johnson/Evinrude three-cylinder outboard engines from 60 to 75 HP. It is intended for water pump service in the lower unit and helps restore proper cooling-water circulation when worn pump components are causing reduced flow or overheating symptoms.
The company fitment record identifies this product for the engine applications listed below. Because water pump configurations can vary by gearcase and model year, compare your engine model and the original part reference before ordering.
- For selected Johnson/Evinrude three-cylinder 2-stroke and 4-stroke outboards.
- Installs in the lower-unit water pump assembly.
- Aftermarket replacement for service and preventive maintenance.
- Do not assume that every gasket, seal, fastener, housing, or wear plate is included unless it is confirmed for the specific package supplied.

- Remove the water pump cover and inspect the pump housing, wear surfaces, keyway, gaskets, and seals.
- Compare the replacement components with the parts removed from the engine before assembly.
- Clean all mating surfaces and remove old gasket material, corrosion, and debris.
- Install only the components supplied in the purchased configuration, following the correct orientation for the impeller and key.
- Use the service manual for the specific engine to apply the correct sealant, fastener sequence, and torque specifications.
- Reinstall the lower unit, reconnect the shift linkage, and test the engine with an appropriate water supply.
- Confirm a strong tell-tale water stream and monitor the engine for overheating before normal operation.
Troubleshooting & FAQ
How do I confirm that this kit fits my engine?
Match the brand, three-cylinder configuration, horsepower, stroke, model year, gearcase, and original water-pump reference with the compatibility information above. When any of these details differ, consult the engine service manual or confirm the original pump part number before ordering.
What are the signs of a worn water-pump impeller or service assembly?
Common signs include weak or absent tell-tale flow, an overheating warning, reduced cooling-water circulation, or visibly cracked, brittle, damaged, or worn pump components.
Does this listing include a water-pump housing?
The company catalog describes water-pump service-kit configurations both with and without a housing but does not specify the exact package contents in the listing record. Confirm the supplied configuration before purchase if a housing is required.
Is this an OEM part?
No. This is an aftermarket replacement/service kit. Johnson/Evinrude, Sierra Marine, Mallory Marine, and GLM numbers shown on this page are manufacturer or aftermarket reference numbers used for identification and compatibility checking.
Should I replace the water pump on a schedule?
Inspect the water-pump assembly during regular maintenance and whenever cooling performance changes. Replacement intervals depend on operating conditions, water quality, service history, and the recommendations in the engine manufacturer's service manual.
Is professional installation recommended?
Yes. Lower-unit removal and water-pump service require correct assembly and adjustment of the shift linkage. Use the service manual for the specific engine, and seek professional installation if you are not experienced with outboard lower-unit service.
Safety & Important Information
- Verify the exact engine model, year, stroke, gearcase, and original part reference before ordering.
- Do not operate an outboard without an adequate water supply for cooling.
- Never run the engine if the tell-tale flow is weak or absent, or if an overheating warning occurs.
- Inspect all supplied and reused components before installation and replace damaged parts.
- This is an aftermarket replacement, not an OEM component.
