How to fix a drowned outboard motor?

Boating can be a thrilling and exciting activity, but when something goes wrong with your engine, it can quickly turn into a frustrating experience. One common problem that boaters may encounter is a drowned outboard motor. This can happen if water gets into the engine, causing it to stop working properly. But don’t worry, with a bit of know-how, you can fix a drowned outboard motor and get back on the water in no time.

Step 1: Assess the Situation

The first step in fixing a drowned outboard motor is to determine the extent of the damage. If the motor stopped working due to a brief dunk in the water, it may just need to dry out. However, if it was submerged for a longer period, there may be more serious damage.

Step 2: Remove the Spark Plugs

Once you have assessed the situation and determined that it is safe to proceed, the next step is to remove the spark plugs. This will allow any water that may have made its way into the cylinders to escape. Turn off the engine and carefully remove each spark plug. If you notice any water or debris, use a cloth to clean it out and dry the spark plugs thoroughly.

Step 3: Drain the Fuel

If any water has made its way into your fuel tank, it is essential to drain it out. Having contaminated fuel can harm your engine and cause corrosion. Connect a fuel line to the motor and a container to catch the fuel. Once connected, turn on the engine and let the fuel drain until only clean fuel is coming out.

Step 4: Check the Oil and Gearbox

It is also important to inspect the oil and gearbox for water contamination. Drain both fluids and replace them with fresh oil and lubricant. Make sure to run the engine for a brief amount of time to circulate the fluids throughout the motor.

Step 5: Clean and Dry

After draining the fuel and inspecting the fluids, it is essential to clean and dry your engine. Use a cloth to remove any debris, and then thoroughly dry all surfaces. Make sure to pay attention to any electrical components, as water can cause damage to these sensitive parts. Once everything is dry, reassemble the motor, including the spark plugs.

Step 6: Test the Motor

The final step is to test your motor to ensure it is working correctly. Start the engine and let it run for a few minutes to check for any issues. If everything sounds and feels normal, you should be good to go.

A drowned outboard motor may seem like a daunting problem, but with the right knowledge and tools, repairing it is relatively straightforward. By following these steps and taking the time to ensure that everything is clean and dry, you can have your engine up and running in no time. Remember, prevention is always better than cure, so make sure to take the proper precautions to protect your engine from water damage in the future. Happy boating!
