A watercraft propulsion system (100) includes a bow thruster (BT) at a bow of a hull (2) to generate a lateral propulsive force, at least two propulsion devices (OM) on a stern (3) of the hull (2) each having a variable steering angle, and a controller (50) configured or programmed to control the propulsive force of the bow thruster (BT) and control the propulsive forces and the steering angles of the two propulsion devices (OM) to perform an azimuth control to control an azimuth of the hull (2). The azimuth control includes a bow thruster mode in which the bow thruster (BT) is controlled, and a combinational mode in which the bow thruster (BT) is controlled and the two propulsion devices (OM) are driven forward and in reverse, respectively. The controller (50) switches between the bow thruster mode and the combinational mode based on a predetermined switching condition during the azimuth control.
