Electric outboard motor
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.Wikipedia
