An electromechanical lockout device for a remote control on a marine vessel includes an electric actuator and a locking pin having an engagement end and a second end. The locking pin is arranged with respect to a control lever such that the locking pin is positionable in a locked position, where the engagement end of the locking pin prevents rotation of the control lever into a reverse position, and in a retracted position, where the engagement end of the locking pin allows rotation of the control lever into the reverse position. A method of controlling lockout for a remote control includes sensing a position of a control lever, calculating a rate of change of the position, and engaging a lockout to prevent a gear system from shifting into reverse gear if the rate of change exceeds a threshold rate of change.

An electronic Control system for controlling a water vessel in regards to its propulsion, and thrust vectors and its steering.A helm wheel that has an electronic output that governs the steerage of a water vessel. The control system determines the reactive speed and number of turns needed to accomplish a given turn, this pre-selected speed and distance traveled gives the rudder two different sets of parameters for full rotation of the Helm wheel from full rudder to the Port to full rudder to the starboard The rudder or outboard motor has a sensor that gives the control system information by way of a variable voltage as to its direction and where the rudder is parked.The steering actuator has a dual motor set up that supply's enough power and torque to control the steering cable and slide bar of three outboard engines.The Control system's other input is a joystick controller, its output governs the direction of the propulsion of the watercraft in either a forward direction or Aft or reverse direction and in the same movement the throttle will ramp up in rpm's proportionately. The operators movement of the joystick controller determines this control command.The joystick in its y-axis has built in friction forces that enable it to stay where the operator moves it.

A system that controls speed of a marine vessel includes first and second propulsion devices that produce first and second thrusts to propel the marine vessel. A control circuit controls orientation of the propulsion devices between an aligned position in which the thrusts are parallel and an unaligned position in which the thrusts are non-parallel. A first user input device is moveable between a neutral position and a non-neutral detent position. When the first user input device is in the detent position and the propulsion devices are in the aligned position, the thrusts propel the marine vessel in a desired direction at a first speed. When a second user input device is actuated while the first user input device is in the detent position, the propulsion devices move into the unaligned position and propel the marine vessel in the desired direction at a second, decreased speed without altering the thrusts.

A power assisted hydraulic steering system comprises a helm pump hydraulically connected to a first hydraulic actuator. A power assist pump is hydraulically connected to a second hydraulic actuator. The first and second hydraulic actuators are coupled. A flow sensing mechanism is disposed along a hydraulic conduit which hydraulically connects the helm pump to the first hydraulic actuator. The flow sensing mechanism senses when fluid flows from the helm pump to the first hydraulic actuator. A motor actuates the power assist pump when the flow sensing mechanism senses that fluid is flowing from the helm to the first hydraulic actuator. In one embodiment the first hydraulic actuator is a servo cylinder and the second hydraulic steering actuator is a drive cylinder.
