Abstract: A watercraft propulsion system has a control lever for giving instructions regarding the operating mode as well as the amount of output power from a source of driving force, and a controller for setting a propeller driving mode according to the instruction given by the control lever. When a reverse mode is instructed by the control lever, the controller sets the propeller driving mode depending on certain considerations such as user settings and battery charge. For instance, the controller may set the propeller driving mode to a mode in which the propeller is rotated in reverse by an electric motor or by the engine. Also, the controller may regulate electric power supply to the motor in light of battery charge. Other combinations are also contemplated.

Abstract: A watercraft propulsion system can be a hybrid type watercraft propulsion system including an engine and an electric motor both working as drive power sources for a propeller. When an operating lever instructs a speed reduction assist mode as a stopping mode, a controller can stop the engine and reverse the rotational direction of the electric motor to reversely rotate the propeller. The controller can determine whether the speed reduction assist mode is instructed or not based upon a mean movement speed of the operating lever and can control the electric motor based upon a speed of the watercraft. Alternatively, the controller can control the electric motor based upon instructions by the speed reduction assist lever.

Abstract: A boat propulsion unit includes an electric motor, a potentiometer arranged to detect the rotating angle of a throttle grip, a first stop mode sensor, a second stop mode sensor, and a controller including a CPU, and a disconnection and short detecting circuit. If the voltage signal fed by the disconnection and short detecting circuit is out of the specified range, the CPU detects the operation mode designated by the throttle grip based on the switching of the outputs from the first stop mode sensor and the second stop mode sensor. Then, the electric motor is driven in the forward operation mode and with the specified output power when the forward operation mode is designated, whereas, the electric motor is driven in the reverse operation mode and with the specified output power when the reverse operation mode is designated. Using this arrangement, the boat propulsion unit can obtain a minimum required boat operation as intended by the boat operator even when an abnormality has occurred in the controls.
