Installation Guide

1. Safety First: Disconnect the battery and remove the spark plug wires to prevent accidental starting.
2. Drain Gear Oil: Place a drain pan under the lower unit and remove the upper and lower gear oil drain screws to drain the lubricant.
3. Remove Lower Unit: Unbolt the lower unit (gearcase) from the engine's midsection. You may also need to disconnect the shift linkage.
4. Access Water Pump: With the lower unit removed, locate and unbolt the water pump housing, typically secured with four screws.
5. Inspect and Clean: Remove the old impeller, gaskets, wear plate, and housing. Clean all mating surfaces thoroughly, removing any old gasket material or corrosion.
6. Install New Components: Install the new wear plate and gasket. Slide the new impeller key onto the drive shaft.
7. Install Impeller: Lubricate the inside of the new housing and install the new impeller, turning the driveshaft clockwise to bend the vanes in the correct direction.
8. Reassemble Pump: Place the new housing over the impeller and secure it with the provided screws and washers, tightening them to the manufacturer's specified torque.
9. Reinstall Lower Unit: Reconnect the shift linkage (if applicable) and carefully guide the lower unit back into place, ensuring the driveshaft, water tube, and shift shaft align correctly. Bolt it securely.
10. Refill Gear Oil: Use a pump to fill the gearcase with fresh marine gear lubricant through the bottom hole until it emerges from the top hole. Reinstall both drain screws securely.
11. Final Checks: Reconnect the battery and spark plug wires. Start the engine in a test tank or with a water flusher to confirm water is pumping correctly from the tell-tale outlet.

Troubleshooting & FAQ

Q: How do I know if this water pump kit will fit my specific engine model?

A: The best way to ensure fitment is to match your engine's model and year to the "Compatible Engine Models" table. Additionally, cross-reference your existing part number with those listed in the "Part Number Cross-Reference" section. This kit is specifically for Johnson/Evinrude outboards with a split case lower unit design and thru-prop exhaust.

Q: What are the common signs of a failing water pump impeller?

A: A weak or intermittent stream from the "tell-tale" water outlet is the most common indicator. Other signs include the engine overheating alarm sounding, steam from the exhaust, or a noticeable drop in engine performance as the ECU reduces power to prevent damage.

Q: How often should I replace my outboard's water pump impeller?

A: As a general rule, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use, whichever comes first. Usage in saltwater or sandy/murky water may require more frequent replacement.
