Installation Guide

1. Preparation: Disconnect the battery and remove the propeller for safety. Drain the lower unit gear oil completely using the drain screw.
2. Access the Water Pump: Remove the lower unit from the mid-section according to your service manual. Disconnect shift linkage carefully and note the position of all components.
3. Remove Old Components: Disassemble the water pump housing and remove the old impeller, gaskets, and seals. Inspect the pump housing for wear or damage.
4. Install New Water Pump Kit: Install the new impeller from kit 5001595, ensuring blades are oriented correctly per rotation direction. Apply marine grease to the impeller and housing.
5. Replace Thermostats: Remove the old thermostats from the cylinder head and install both new thermostats (435491) with proper orientation. Ensure mating surfaces are clean.
6. Install Anodes: Replace old sacrificial anodes with new anodes 436745 and 433580 at their designated locations. These protect against galvanic corrosion.
7. Replace Drain Gaskets: Install new drain screw gaskets (311598) on both upper and lower drain screws to prevent gear oil leaks.
8. Install Gear Oil Pump: Attach the new gear oil pump (24OP149) to facilitate easier lower unit oil changes in the future.
9. Reassemble Lower Unit: Reinstall all pump housing components with new gaskets and seals. Torque all fasteners to manufacturer specifications.
10. Refill Gear Oil: Using the new gear oil pump, refill the lower unit with appropriate marine gear lubricant until it flows from the upper vent hole.
11. Final Assembly: Reattach the lower unit to the mid-section, reconnect shift linkage, and verify proper shifting operation. Reinstall the propeller.
12. Test Operation: Reconnect the battery and run the engine with a water supply (muffs or test tank). Verify strong water discharge from the tell-tale indicator and check for leaks.

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 be between 90-175 HP manufactured between 1995-2006. You can also verify your engine's serial number using the Johnson/Evinrude serial number guide linked in the compatibility section.

Q: How often should I replace the water pump and related cooling system components?
A: Most manufacturers recommend replacing the water pump impeller every 2-3 years or 200-300 hours of operation, whichever comes first. Thermostats should be inspected annually and replaced if they show signs of corrosion or fail to open/close properly. Anodes should be replaced when 50% depleted.

Q: What are the signs that my water pump or cooling system needs service?
A: Common symptoms include weak or no water flow from the tell-tale indicator, engine overheating, steam from the engine, reduced performance, or an overheating alarm. If you notice any of these signs, inspect and service the cooling system immediately to prevent engine damage.

Q: Can I install this kit myself or do I need a marine mechanic?
A: If you have mechanical experience and the proper tools, this installation can be performed at home following your engine's service manual. However, the process requires removing the lower unit and precise reassembly. If you're unsure about any step, professional installation is recommended to ensure proper function and avoid costly mistakes.

Q: Why are two thermostats included in this kit?
A: Johnson/Evinrude outboards in this horsepower range typically use a dual-thermostat cooling system for more precise temperature regulation. Both thermostats should be replaced together to ensure balanced cooling performance and prevent one side from running hotter than the other.
