Abstract

The present watercraft propulsion system (100) includes a principal propulsion device (3), an auxiliary propulsion device (4), a steering actuator (33), a steering motor (56), and a main controller (101). The principal propulsion device (3) is attached to a hull (2) of a watercraft. The auxiliary propulsion device (4) is attached to the hull (2) and has a smaller rated output than the principal propulsion device (3). The steering actuator (33) changes a rudder angle of the principal propulsion device (3). The steering motor (56) changes a rudder angle of the auxiliary propulsion device (4). The main controller (101) controls the steering actuator (33) and the steering motor (56) such that a rudder rate of the principal propulsion device (3) is made smaller than a rudder rate of the auxiliary propulsion device (4) when steering of the hull 2 is executed in a state that not the principal propulsion device (3) but the auxiliary propulsion device (4) only generates a thrust.
