1. A propulsion system on a marine vessel, the system comprising:
at least one steerable propulsion device rotatable to steer a marine vessel;
at least one lateral thruster configured to generate starboard and/or port thrusts to propel the marine vessel;
a steering wheel operable by a user to steer the at least one propulsion device;
a user input device operable by a user to provide at least a lateral thrust command to command lateral movement of the marine vessel and a rotational thrust command to command rotational movement of the marine vessel;
a controller configured to:
determine a steering position of the at least one propulsion device;
determine a difference between the steering position and a centered steering position;
control a user interface device to indicate at least one of the steering position and the difference between the steering position and the centered steering position to a user; and
determine that the steering position is within a threshold range of the centered steering position prior to enabling a joystick thrust control mode wherein thrust by the at least one propulsion device and the lateral thruster is controllable by the user input device.
