an outboard motor attachable to a ship;

a rudder motor that drives a rudder mechanism of the outboard motor;

a handle which is mechanically separated from the rudder mechanism, and which is capable of electrically operating the rudder mechanism;

a steering angle detecting unit that detects a steering angle of the handle;

a reaction force motor that generates reaction force torque to be applied to the handle;

a storing unit that stores a steering characteristics map which associates a basic relation between the steering angle and a turn angle of the outboard motor; and

a turn controller that controls, based on the steering characteristics map, a drive current value which drives the rudder motor so as to obtain the turn angle in accordance with the steering angle,

wherein the steering characteristics map has a first steering region in which the steering angle is a first steering angle that is between zero and an upper boundary steering angle and a second steering region in which the steering angle is a second steering angle that is greater than the first steering angle in the first steering region, and wherein a change amount of the turn angle relative to the second steering angle is larger than a change amount of the turn angle relative to the first steering angle.
