Abstract
A marine propulsion system includes a controller configured or programmed to perform a rudder angle change control to change a rudder angle of an auxiliary propulsion device by a predetermined angle to one side in a right-left direction of a hull with respect to a forward-rearward direction of the hull so as to move the hull along the forward-rearward direction without rotating the hull when motorized forward-rearward movement is performed to move the hull along the forward-rearward direction by driving the auxiliary propulsion device that is provided to one side of the hull in the right-left direction without generating a thrust from a main propulsion device.
