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.
Outboard motor
InactiveUS20060025025A1Increase costIncrease in sizePropulsion based emission reductionPower plants using propulsion unit combinationsElectric outboard motorElectric machine
An outboard motor is equipped with a centrifugal clutch located between the crankshaft of an engine and a rotor of an electric motor for, when the engine operates, transmitting its output to through the rotor to a propeller, and with a motor output transmission mechanism for, when the engine does not operate, transmitting the output of the motor to the crankshaft. The engine can therefore be started by the motor used to drive the propeller. As a result, there is no need to install a separate electric motor for engine starting, so that starting of the engine by electric power can be made possible with minimum increase in the size and cost of the outboard motor.

In an outboard motor, a controller controls an electric motor. An output outputs a predetermined notification information in response to a notification command signal output from the controller. When the controller receives a shut-off signal indicating that a semiconductor fuse is off, the controller outputs the notification command signal and causes the output to output notification information. When the controller receives a recovery operation signal indicating a predetermined operation performed by a user from an operator in a state where the semiconductor fuse has turned off, the controller outputs a recovery command signal to the semiconductor fuse.
