Installation Notes

Troubleshooting & FAQ
How do I know if this repair kit fits my engine?
Check that your engine is a Johnson/Evinrude 1.5 HP or 2 HP 2-Stroke model within the listed year range and that the gearcase configuration matches the application. Compare the original water-pump components and OEM reference before ordering.
Is the steel wear plate included?
No. This listing is for the repair-kit configuration without a steel plate. Inspect your existing plate and purchase the correct replacement separately if it is worn, scored, warped, or damaged.
Is a drive-shaft key or pin included?
The available manufacturer record does not specify a separate key or pin as included. Do not assume that one is supplied; inspect the original assembly and confirm the package contents before installation.
Does this fit a Johnson/Evinrude 4 HP or 6 HP outboard?
The manufacturer-linked application for this listing specifies 1.5 HP and 2 HP models and selected 490 gearcase applications. Do not use the earlier 4 HP or 6 HP claims as confirmation of fitment.
Is this an OEM part?
This listing is for an aftermarket repair kit. The referenced OEM numbers are provided for application and part-number comparison only.
What are the signs of a failing water pump impeller?
Common symptoms include weak or absent cooling-water flow, overheating, or reduced cooling performance. Stop operation if the engine overheats and inspect the water-pump system before further use.
How often should the water-pump components be inspected?
Inspect the water-pump components during routine seasonal maintenance and whenever cooling performance changes. Replacement intervals depend on operating hours, storage conditions, and exposure to sand, silt, or debris.
Safety & Important Info
- Verify the complete engine model, year, stroke, gearcase configuration, and original part number before purchase.
- Do not assume that the steel plate, key, pin, gaskets, housing, or other service parts are included unless specifically listed.
- Use the manufacturer's service procedure and specified torque values during installation.
- Professional installation is recommended if you are not experienced with outboard lower-unit service.
