A steering system on a marine vessel includes a steering wheel movable by a vessel operator to steer the marine vessel and a variable resistance device controllable to apply a variable resistance amount to resist movement of the steering wheel. The system includes a control unit that controls the variable resistance device to determine a baseline resistance amount based on vessel speed and/or engine RPM and detect at least a threshold change in angular position of the marine vessel. The control unit then controls the variable resistance device to prevent a decrease in the resistance amount below the baseline resistance amount or to increase the resistance amount above the baseline resistance amount.

Marine steering system and method of providing steering feedback

A joystick device for controlling propulsion and steering of a marine vessel has a handle configured to be moveable by an operator to provide propulsion and steering control commands for a marine vessel, and a housing at the base of the handle such that the handle extends out of the housing. The joystick device also has an adjustable display thereon that adjusts based on at least one of a control mode and a movement of the handle.

Systems and methods for controlling a marine vessel having a joystick with adjustable display

A user input device for controlling steering and/or propulsion of a marine vessel includes a movable member movable by a vessel operator to control the steering and/or propulsion of the marine vessel, a variable resistance device controllable to vary resistance to movement of the movable member, and a controller that controls the variable resistance device. The controller is configured to detect an unstable condition indicator and, upon detecting the unstable condition indicator, control the variable resistance device to increase resistance to movement of the movable member.

Device and method for providing user input control on a marine vessel

A propulsion and steering control system for a marine vessel has a joystick device operable to provide control commands, the joystick device having a handle extending on an axis. The control system also has a control unit that receives control commands from the joystick device and correspondingly controls at least one marine drive. The joystick device and the control unit operate in a Heading mode such that the control unit controls the marine drive to automatically maintain the selected heading of the marine vessel. Rotation of the handle about the axis adjusts the selected heading by a predefined increment.

Heading control on a marine vessel

A method for positioning a drive unit on a marine vessel includes receiving an initiation request from a user input device to operate the marine vessel in a desired operating mode and storing a first trim position of the drive unit in a memory upon receiving the initiation request. The method includes trimming the drive unit to a second trim position in response to the initiation request and subsequently operating the marine vessel in the desired operating mode with the drive unit in the second trim position. The method includes receiving a termination request to cancel the desired operating mode and trimming the drive unit to the first trim position automatically upon receiving the termination request. A system for positioning the drive unit is also disclosed.
