Abstract
In a watercraft propulsion system, when a magnitude of a command value indicated by a propulsion signal falls within a first range in a composite operation, a controller controls a first outboard motor to increase a thrust in a propulsion direction and simultaneously causes a second outboard motor to reduce a thrust in an opposite direction. When the magnitude of the command value falls within a second range in the composite operation, the controller controls the first outboard motor to make the thrust in the propulsion direction greater than when the magnitude of the command value falls within the first range and simultaneously maintains the second outboard motor in a neutral state. When the magnitude of the command value falls within a third range in the composite operation, the controller controls the first outboard motor to make the thrust in the propulsion direction greater than when the magnitude of the command value falls within the second range and simultaneously controls the second outboard motor to generate a thrust in the propulsion direction.
