When it comes to storing your boat after a long day of fishing or cruising, it’s essential to drain all the water from your outboard motor, preventing any potential damage that may occur over time. Draining your outboard motor, including its cooling system, is something every boat owner should know how to do. If you’re new to boating or haven’t done it before, we have some easy steps to follow to drain all the water from an outboard motor.
Step One: Disconnect the Fuel Line
Start by disconnecting the fuel line from the outboard motor. This step ensures that no gasoline or oil spills during the draining process, resulting in a potential environmental hazard.
Step Two: Start the Motor
Turn on the motor and let it run in neutral for about 10 to 15 minutes. This process helps flush out any remaining water from the engine block and cooling system.
Step Three: Turn Off the Motor
Once the motor runs for about 10 to 15 minutes, turn it off completely.
Step Four: Open the Engine Cover
With the engine completely off, open the engine cover and locate the water pump on the motor’s side. On the water pump, find the water intake screen and remove it.
Step Five: Tilt the Motor
You need to tilt the engine up and rest it on its tilt support lever. This process is vital when draining all the water sitting in the engine’s cooling system.
Step Six: Remove the Drain Plug
Using a pair of pliers, remove the drain plug located near the bottom of the motor. You’ll notice water flowing out of the drain hole. Allow the water to drain completely.
Step Seven: Replace the Drain Plug
Once all the water has been drained, put the drain plug back and tighten it firmly.
Step Eight: Remove the Water Pump Impeller
Locate the screws that hold the water pump in place and take them out. Gently remove the water pump to access the impeller. Take a close look at the impeller, ensuring there are no cracks, wear and tear or damage. Replace the impeller if needed.
Step Nine: Reassemble the Outboard Motor
Once you’ve completed all the steps, reassemble the outboard motor, making sure everything is firmly in place. Finally, connect the fuel line, and you’re done.
In a nutshell, draining all water from an outboard motor is essential for long-term maintenance. We acknowledge that boat owners are pressed for time, but this process doesn’t take long and can potentially save you from significant problems down the road. Just follow the above steps, and you’ll be good to go.
