Turn it on... Does it work ?
Yes - job done
No - Bummer!
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
To test a motor, use a megger (megohm meter) to test the insulation of the internal motor windings. Select a voltage to apply to the motor using an output from the megger that is higher that the operating voltage that the motor operates on.
A megger is used to test the resistance of high voltage cables, insulation and motor windings. The test employs a megohm meter.
If you connect the test leads to the brushes of a DC electric motor, you would typically measure the resistance across the armature circuit. This reading can help you determine the condition of the armature winding, the brushes, and the connections.
To effectively test a boat motor out of water, you can use a motor test tank or a flushing attachment. These tools allow you to run the motor safely and check for any issues without needing to be in the water. It's important to follow the manufacturer's instructions and safety guidelines when testing a boat motor out of water.
Electric motors do not produce electricity, they use electricity, and convert that energy to another form of energy, that we measure in horsepower. See related links.
To test a boat motor out of water, you can use a motor muffs or a flushing attachment to connect a hose to the motor's water intake. This will allow you to run the motor without it being in the water, ensuring it is functioning properly. Be sure to follow the manufacturer's instructions and safety precautions when testing the motor out of water.

Even if you know how to reconnect it safely, you can probably be charged with theft if you reconnect it without authorization. Whatever the reason it was disconnected, the electric company may want to inspect or test the connected wiring to be sure it is suitable condition to be reconnected. You will not likely be authorized to connect it yourself. Likely only electric company personnel or a licensed electrician would be authorized.
The first step is finding what the issue is. Check the fuse to the motor. If you have access to a volt meter or test light, check to make sure that the motor is getting power when the switch is on. If power is there then the motor needs to be replaced.
You use a device called a megger or meg ohm meter. Have the voltage range of the megger set to the working voltage of the motor. The first test should be to ground. One lead on the frame of the motor , the other lead one of the 6 wires. Test all 6 wires. If no ground shows up, test the individual coils against one another. If the coils are not grounded together, the motor is safe to energize.
One innovative idea for a science fair project involving an electric motor is to investigate the effect of different types of magnets on the motor's performance. Another idea could be to build a small-scale electric vehicle and test how different factors, such as weight or wheel size, impact its speed and efficiency.
