ABSTRACT:
In an outboard motor control system, an electronic control unit executes ordinary navigation in which the operation of at least one among a steering motor, throttle motor and shift motor is controlled in accordance with an operator command inputted from the steering wheel or shift/throttle lever (steering command, shift position change command or engine speed regulation command of the outboard motor) and executes autopilot navigation in which the boat is automatically navigated by controlling the operation of the individual electric motors based on boat position information inputted from a GPS plotter and the desired position of the boat. This simplifies the configuration for conducting both manual navigation and automatic navigation and avoids making the system larger or more complicated to install, while including boat speed regulation and stopping capability among the autopilot features.
