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 marine outboard engine has an engine, a cowling, an alternator, and a controller electrically connected to the alternator. A primary charger is electrically connected to the alternator and is adapted to charge a primary energy storage device. A starter motor is selectively operatively connected to the engine and is adapted to be electrically connected to the primary energy storage device. An auxiliary charger is electrically connected to the alternator and is adapted to charge at least one auxiliary battery adapted to power an auxiliary device. The controller, the primary charger and the auxiliary charger are disposed inside the cowling. A vehicle bus connects the auxiliary charger with the controller to provide data from the controller to the auxiliary charger. A watercraft having the marine outboard engine and an auxiliary device is also disclosed.

Abstract: An exhaust valve system for a two-stroke internal combustion engine having: at least one exhaust valve movable between open and closed positions; an actuator for moving the at least one exhaust valve; a valve position sensor; a controller communicating with the actuator and the valve position sensor. The controller being programmed for: controlling the actuator to attempt to move the at least one exhaust valve to a desired one of the open and closed positions; determining if the at least one exhaust valve has failed to reach the desired position based on the position of the at least one exhaust valve sensed by the valve position sensor; and controlling the actuator to move the at least one exhaust valve to an intermediate position when the at least one exhaust valve has failed to reach the desired position.
