Abstract: 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.

Abstract: A bracket assembly for a marine outboard motor has a stern bracket, a swivel bracket pivotably connected to the stern bracket to pivot relative to the stern bracket about a tilt axis, a motor mount pivotably connected to the swivel bracket to pivot relative to the swivel bracket about a steering axis, a steering lock bracket operatively connected to the motor mount and being pivotable with the motor mount relative to the swivel bracket about the steering axis, and a locking member. The locking member is one of: a) movably connected to the swivel bracket to move between a locked and an unlocked positions, and b) removably connected to both the swivel bracket and the steering lock bracket to prevent or limit pivoting of the motor mount about the steering axis.

Abstract: A marine engine for propelling a watercraft has a drive unit adapted to be pivotally connected about a steering axis to the watercraft, and a steering position sensing system. The steering position sensing system has a magnet housing operatively connected to the drive unit and having an arcuate portion, a magnet disposed in the magnet housing, a sensor housing adapted to be operatively connected to the watercraft and a sensor disposed in the sensor housing. The magnet housing and the magnet are pivotable about the steering axis with the drive unit and relative to the sensor housing. The arcuate portion of the magnet housing is spaced from the sensor housing. The sensor senses a magnetic field of the magnet to determine an angular position of the drive unit relative to the watercraft. A bracket assembly for mounting an outboard engine to a watercraft is also disclosed.
