Electric outboard motors are an option for boat propulsion. Most electric outboard motors have 0.5 to 4 kW direct current electric motors, operated at 12 to 60 volts DC. These systems have the propeller fixed directly to the motor, which is mounted in the lower unit under water – see trolling motor. This setup limits the power output. Recently developed outboard motors are powered with an alternating current or DC electric motor in the power head like a conventional petrol engine. With this setup, a motor can produce 10 kW output or more and is able to replace a petrol engine of 15 HP or more. The advantage of the induction or asynchronous motor is the power transfer to the rotor by means of electromagnetic induction. As these engines do not use permanent magnets, they require less maintenance and develop more torque at lower RPM.
