Abstract:
A watercraft comprising a water propulsion device, an engine powering the water propulsion device, an engine output control mechanism arranged to control the output of the engine, a steering mechanism arranged to steer the watercraft, a first sensor arranged to sense a state of the engine output control mechanism, a second sensor arranged to sense a state of the steering mechanism, and a control device configured to control the engine output control mechanism based upon a first control parameter corresponding to an output of the first sensor and a second control parameter corresponding to an output of the second sensor, the control device being configured to cause the engine output control mechanism to increase engine output in a predetermined gradual or step by step manner when the first control parameter is less than a first reference magnitude and the second control parameter is greater than a second reference magnitude.
