Installation Guide

1. Disconnect the fuel line and remove the engine cowling to access the lower unit. Ensure the engine is completely cool before beginning work.
2. Drain the existing gear oil from the lower unit using the drain and vent screws. Inspect the old oil for metal particles or discoloration.
3. Remove the propeller, then unbolt the lower unit from the mid-section and carefully separate it. Mark hose positions for reassembly.
4. Remove the water pump housing by unbolting the securing screws. Take note of the impeller orientation before removal.
5. Clean all mating surfaces thoroughly, removing old gasket material and debris. Inspect the housing for wear or corrosion.
6. Install the new water pump components from the kit, ensuring the impeller blades are oriented in the correct rotation direction. Apply marine grease to the impeller for initial lubrication.
7. Replace the drain screw gaskets (311598) on both drain and vent screws. Tighten screws to manufacturer specifications.
8. Install both new thermostats (435491) into their housings with fresh gaskets. Ensure proper seating to prevent coolant bypass.
9. Reassemble the water pump housing and lower unit, torquing all bolts to specification in a cross-pattern. Verify alignment before final tightening.
10. Refill the lower unit with fresh gear oil using the included gear oil pump (24OP149) through the lower drain hole until it flows from the upper vent. Replace both plugs with new gaskets.
11. Reinstall the propeller with a new cotter pin and reattach the lower unit to the mid-section. Double-check all fasteners.
12. Test the engine in a water tank or on-the-water, checking for strong water stream from the telltale and monitoring engine temperature. Inspect all seals for leaks during the first run.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Johnson/Evinrude engine?
A: Cross-reference your engine's horsepower and year with the compatibility table above. Your engine should fall within 90-175 HP and be manufactured between 1995-2006. You can also verify your engine serial number using our Johnson/Evinrude serial number guide linked above.

Q: What are the signs that my water pump needs replacement?
A: Common symptoms include weak or no water flow from the telltale (indicator stream), engine overheating, steam from the engine, or reduced performance. Water pumps should typically be replaced every 2-3 years or 200-300 hours of operation as preventive maintenance.

Q: Why does this kit include thermostats and a gear oil pump?
A: The thermostats regulate engine temperature and should be replaced during water pump service to ensure optimal cooling system performance. The gear oil pump facilitates proper lower unit maintenance, allowing you to refill gear oil after servicing the water pump.

Q: How often should I replace the water pump on my outboard?
A: Most manufacturers recommend replacing the water pump impeller every 2-3 years or 200-300 hours of use, whichever comes first. If you operate in sandy or debris-filled water, more frequent replacement may be necessary.
