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.
