Example steering control systems and methods for multiple devices are provided herein. A system includes a trolling motor assembly having a propulsion motor and a steering actuator and a sonar assembly comprising a transducer assembly and a directional actuator. The system further includes a user input assembly that is configured to detect user activity related to controlling operation of the trolling motor assembly and operation of the sonar assembly. The system further includes a processor that is configured to determine a direction of turn based on user activity, generate an electrical turning input signal indicating the direction of turn, and direct either one or both of the steering actuator and the directional actuator, via the turning input signal, to adjust a direction of either one or both of the propulsion motor and the transducer assembly accordingly.

An outboard motor includes an outboard motor main body and a mount assembly to mount the outboard motor main body to a hull. The mount assembly includes a clamp bracket to be fixed to the hull, a swivel bracket to support the outboard motor main body, and a hydraulic cylinder. The swivel bracket is coupled to the clamp bracket through a tilt shaft and turnable around the tilt shaft. The hydraulic cylinder is located between the clamp bracket and the swivel bracket and is able to turn the swivel bracket around the tilt shaft with respect to the clamp bracket. The outboard motor includes a gas damper to damp an external force that acts in a telescopic direction of the hydraulic cylinder.

A control system for a watercraft can provide various modes of joystick propulsion control including cruise control, sub-idle watercraft speed operation, composite lateral propulsion, and shiftless docking maneuvers. The system can be used with peripheral motors having retractable 360-degree rotatable units together with a central motor both of which have mechanism to selectively deploy or retract their propellers in and out of water by a controller by manually or automatically.

A power steering system for a watercraft includes an electromechanical rotary actuator mounted within a cylindrical housing. The electromechanical rotary actuator includes a motor and a gearing system. The housing, along with a stern bracket and an output flange, are sized and arranged to permit steering movements and trim/tilt movements of an outboard motor. The power steering system may include one or more of a redundant linear actuator, a trim/tilt mechanism, and a control system.

A marine propulsion system includes a main propulsion device including a main thruster, an auxiliary propulsion device to be attached to a stern on one side of a centerline of a hull in a right-left direction and including an auxiliary thruster, and a remote control lever to switch between a neutral state, a forward movement state, and a reverse movement state. The auxiliary propulsion device further includes a tilt device to tilt up and tilt down an auxiliary propulsion device body, and is operable to tilt up the auxiliary propulsion device body with the tilt device when the main propulsion device is switched from the neutral state to the forward movement state by the remote control lever while the auxiliary propulsion device body is tilted down.

A marine propulsion system includes a controller configured or programmed to perform an electric drive control to cause an electric motor to drive an auxiliary thruster in an auxiliary propulsion device and having a minimum output smaller than a minimum output of a main thruster without performing an engine drive control to cause an engine to drive the main thruster in a main propulsion device when adjusting a thrust of a marine vessel to less than a troll thrust.
