Winterizing an old Johnson outboard motor is essential to ensure it remains in good condition during the off-season. Here's how to properly winterize your Johnson outboard motor:
-
Add Fuel Stabilizer: Start by adding the correct amount of fuel stabilizer to the fuel tank. This prevents the fuel from degrading over time, which could lead to issues when you start the engine again.
-
Run the Engine: Connect the motor to a water source and run it for a few minutes. This allows the stabilizer to circulate throughout the fuel system.
-
Fog the Engine: While the engine is running, spray fogging oil into the air intake until the engine begins to stall, then shut it off. Fogging oil coats the internal components, protecting them against rust and corrosion.
-
Fog the Cylinders: Remove the spark plugs and spray fogging oil directly into each cylinder. This additional step helps to ensure that the internal parts are well-coated. Replace the spark plugs after fogging.
-
Drain the Gear Oil: Place an oil pan under the motor, remove the drain plug from the lower unit, and let the old gear oil drain completely.
-
Refill Gear Oil: Refill the lower unit with fresh, marine-grade gear oil. Continue to add oil until it reaches the level of the top fill hole to ensure proper lubrication.
-
Disconnect the Battery: Remove the battery from the motor and store it in a cool, dry place. This helps to prevent the battery from discharging and suffering damage during storage.
-
Lubricate Moving Parts: Apply marine-grade grease to all moving parts such as pivot points and linkage to prevent rust and ensure smooth operation when you use the motor next season.
Following these steps will help maintain the longevity and performance of your Johnson outboard motor. For detailed instructions tailored to your specific model, always consult the manual.
