Product Details
This aftermarket Water Pump Repair Kit is intended for selected Johnson and Evinrude 2-stroke outboard applications using a large gearcase and large water pump with a six-vane impeller. It is designed to service the water pump and help restore reliable cooling-water flow when the existing pump components are worn.
The company catalog identifies this product for selected 40, 45, 50, 55, 60, 65, and 70 HP applications, with different engine, cylinder, year, and commercial-use conditions. Fitment is not determined by horsepower alone, so verify the complete engine model and the existing water-pump reference before ordering.
- Aftermarket water pump repair kit for selected Evinrude and Johnson outboards.
- For specified 2-stroke, large-gearcase water-pump applications.
- Cross-references the Johnson/Evinrude/OMC numbers listed below.
- Aftermarket reference numbers include SEI Marine 96-364-01BK and GLM 12235.

Engine & Model Compatibility
The company fitment information describes the following application groups. The groups must be read together with the gearcase, water-pump, engine-model, year, and commercial-use conditions shown.
| Engine Brand | Rated HP | Stroke / Configuration | Years | Application Conditions |
|---|---|---|---|---|
| Johnson / Evinrude | 40, 45, 55 HP | 2-stroke | 1995–2005 | Selected commercial or carbureted models using the applicable large gearcase and large water pump. |
| Johnson / Evinrude | 40, 50, 60 HP | 2-cylinder, 2-stroke | As specified by the engine application | Selected large-gearcase applications; verify the exact model and water-pump reference. |
| Evinrude | 40, 50, 60 HP | E-TEC 2-stroke commercial | 2004–2005 | Selected commercial E-TEC applications listed by the company catalog. |
| Johnson / Evinrude | 65, 70 HP | 2-stroke loopcharged | 1995 model-year application noted by the company | Large-gearcase applications with the applicable large water pump and six-vane impeller. Verify the exact model before purchase. |
Important: The catalog information does not establish universal fitment for every engine carrying one of these horsepower ratings. Compare the complete model designation, year, gearcase configuration, existing pump reference, and service-manual information before ordering.

What’s in the Box
This listing is for the water pump repair kit identified above. The company catalog does not provide a verified item-by-item package list or confirm the quantity of each component. Do not assume that a water-pump housing, bolts, seals, keys, gaskets, wear plate, or other individual components are included unless they are shown in the product packaging or confirmed for the specific order.
Installation Notes
- Confirm the engine model, year, serial information where applicable, gearcase configuration, and existing water-pump reference before disassembly.
- Disconnect the battery and follow the service-manual procedure for removing the lower unit.
- Remove the existing water-pump components and inspect the housing, wear surfaces, keyway, driveshaft, and mating surfaces for damage or excessive wear.
- Clean the mating surfaces and install the replacement components supplied with the kit according to the engine manufacturer’s service procedure.
- Position the impeller correctly and verify that the vanes are oriented for the specified direction of shaft rotation.
- Use the manufacturer’s torque specifications when fastening the water-pump components and reinstalling the lower unit.
- Run the engine only with an appropriate cooling-water supply. Confirm a steady tell-tale stream and check carefully for leaks or overheating before returning the boat to service.
Professional installation is recommended when lower-unit removal or water-pump service is unfamiliar. Always use the service manual for the specific engine model.
Troubleshooting & FAQ
How do I confirm that this repair kit fits my outboard?
Compare the complete engine model and year with the application conditions above, then verify the existing water-pump reference and gearcase configuration. The horsepower rating alone is not sufficient to confirm fitment.
What are common signs of a worn water-pump impeller?
Typical symptoms include a weak or interrupted tell-tale stream, overheating, an overheating warning, or steam from the exhaust. A damaged impeller can also result in reduced cooling-water flow.
Does this kit fit every Johnson or Evinrude 40–70 HP outboard?
No. The listed horsepower range includes multiple engine families and gearcase configurations. This product is intended only for the selected applications described by the company catalog, so verify the exact model, year, configuration, and reference number before ordering.
Does the package include a complete water-pump housing?
The company record identifies this product as a water pump repair kit but does not provide a verified itemized package list. Confirm the package contents for your order rather than assuming that a housing or any other individual component is included.
Is this an OEM part?
No. This is an aftermarket replacement. The OEM numbers in the cross-reference table are used to help identify the intended application and are not a statement that this product is manufactured by Johnson, Evinrude, or OMC.
When should the water-pump components be replaced?
Replacement timing depends on the engine manufacturer’s maintenance schedule and operating conditions. Inspect the water-pump components during scheduled service and replace them sooner if the engine has been operated in sand, silt, weeds, or salt water, or if cooling performance declines.
Safety & Important Information
- Verify the complete engine model, year, gearcase configuration, and reference number before purchase.
- Do not operate an outboard without an adequate cooling-water supply.
- Use the engine manufacturer’s service manual for removal, installation, torque, and testing procedures.
- This is an aftermarket replacement, not an OEM component.
- Stop operation immediately if the tell-tale stream is weak, the engine overheats, or leakage is observed.
