A steering system for a watercraft has steering position sensors sensing a steering position of first and second outboard motors, hydraulic steering actuators for steering the outboard motors, a hydraulic helm selectively supplying hydraulic fluid to the steering actuators, at least one valve for reversing a direction of flow of hydraulic fluid into the steering actuators, and a steering controller. The steering controller executes a realignment process including: receiving signals indicative of the steering positions of the outboard motors from the steering position sensors; based at least in part on the signals, determining if the outboard motors are misaligned; and, if the outboard motors are misaligned, actuating the at least one valve to direct the flow of hydraulic fluid into a corresponding steering actuator in a direction opposite to that corresponding to an active steering direction set by the hydraulic helm so as to reduce misalignment of the outboard motors.
