- Disconnect the battery where applicable and remove the engine cowling.
- Shift the outboard into neutral and remove the lower unit according to the manufacturer's service procedure.
- Remove the old water pump housing and related components from the top of the gearcase.
- Clean the mounting surfaces, driveshaft, and water pump cavity. Inspect the driveshaft keyway and surrounding parts for wear or damage.
- Install the new gasket, wear plate, liner or insert, impeller, housing, seals, and hardware in the correct order for your engine.
- Position the impeller according to the service manual and rotate the driveshaft as required while lowering the housing over the vanes.
- Torque fasteners to the engine manufacturer's specifications. Do not substitute sealants, lubricants, or fasteners unless permitted by the service manual.

- Run the engine only in a suitable water supply or with the correct flushing equipment. Confirm a steady telltale stream and check carefully for leaks or overheating.
Troubleshooting & FAQ
How do I confirm that this kit fits my outboard?
Check the complete engine model number, year, stroke, gearcase configuration, and original water pump part number. The 5000308 reference is associated with selected Johnson and Evinrude 2-stroke large-gearcase applications, but horsepower alone is not sufficient to confirm fitment.
What are the signs of a failing water pump impeller?
Common symptoms include a weak or missing telltale stream, overheating at idle or low speed, an overheating warning, reduced cooling-water flow, or visible damage to the impeller, wear plate, liner, or housing.
How often should the impeller be replaced?
Inspect and replace the impeller according to the engine manufacturer's maintenance schedule. Replacement intervals may need to be shorter when the engine operates in sandy, silty, weedy, or saltwater conditions.
Does this kit fit every 40–70 HP Johnson or Evinrude engine?
No. The kit is for specific water pump and gearcase configurations. Some engines in the same horsepower range use different impellers, housings, keys, or OEM references. Match the original part number and complete model information before purchase.
Is this an OEM component?
No. This listing is for an aftermarket replacement kit that references Johnson/Evinrude OEM number 5000308 for identification and fitment comparison. It is not manufactured or branded by Johnson or Evinrude.
Can I install the kit without a service manual?
Professional installation or use of the correct engine service manual is recommended. Water pump components must be installed in the correct order and fastened to the manufacturer's specifications to prevent cooling-system failure.
Safety & Important Information
- Verify the complete engine model, year, gearcase configuration, and original OEM reference before ordering.
- Do not rely on horsepower alone to determine compatibility.
- Inspect the driveshaft key, water pump cavity, wear plate, and housing surfaces before installation.
- Never operate an outboard without an adequate water supply or the correct flushing equipment.
- Stop operation immediately if the telltale stream is weak, the engine overheats, or water leaks from the pump assembly.
- This is an aftermarket replacement, not an OEM component.
