A method for steering a marine vessel powered by a marine engine and having a steerable marine device includes initiating a docking mode, and in response to initiation of the docking mode, reducing a steering ratio between input signals corresponding to steered positions of a steering wheel and output signals corresponding to desired steering angles of the marine device, such that the steering ratio is less than the steering ratio would otherwise be were the vessel in a non-docking mode. Input signals are accepted from the steering wheel, and output signals are generated based on the input signals and the reduced steering ratio. The output signals are sent to a steering actuator coupled to the marine device, which controls a position of the marine device to the desired steering angles.

1. A method for steering a marine vessel powered by a marine engine and having a steerable marine device, the method comprising: initiating a docking mode;in response to initiation of the docking mode, reducing a steering ratio between input signals corresponding to steered positions of a steering wheel and output signals corresponding to desired steering angles of the marine device, such that the steering ratio is less than the steering ratio would otherwise be were the marine vessel in a non-docking mode;decreasing a number of lock-to-lock turns of the steering wheel in response to initiation of the docking mode, such that the number of lock-to-lock turns is less than the number of lock-to-lock turns would otherwise be were the marine vessel in the non-docking mode;accepting the input signals from the steering wheel;generating the output signals based on the input signals and the reduced steering ratio;sending the output signals to a steering actuator coupled to the marine device and controlling a position of the marine device to the desired steering angles. 2. The method of claim 1, wherein the reduced steering ratio in the docking mode is linearly related to the steering ratio in the non-docking mode. 3. The method of claim 1, further comprising braking the steering wheel once the steering wheel has been rotated from a neutral, centered position by half the number of lock-to-lock turns. 4. The method of claim 1, further comprising waiting until the steering wheel has passed through a neutral, centered position after initiation of the docking mode before utilizing the reduced steering ratio to generate the output signals. 5. The method of claim 4, further comprising: cancelling the docking mode; andwaiting until the steering wheel has passed through the neutral, centered position after cancellation of the docking mode before discontinuing utilizing the reduced steering ratio to generate the output signals. 6. The method of claim 5, further comprising cancelling the docking mode in response to a key-off/key-on event of the marine engine. 7. The method of claim 1, further comprising initiating the docking mode in response to determining that a given number of alternating forward and reverse gear selections for the marine engine have been made within a given period of time. 8. The method of claim 7, further comprising initiating the docking mode in response to additionally determining that a given number of lock-to-lock turns of the steering wheel have been made within the given period of time. 9. The method of claim 8, further comprising initiating the docking mode in response to additionally determining that a speed of the marine vessel is below a given speed. 10. The method of claim 1, further comprising initiating the docking mode in response to selection of a docking mode option by an operator of the marine vessel. 11. The method of claim 1, further comprising limiting an authority of a throttle lever that controls a position of a throttle valve of the marine engine in response to initiation of the docking mode. 12. A system for steering a marine vessel powered by a marine engine, the system comprising: a steerable marine device coupled to the marine vessel and rotatable to desired steering angles to affect a direction of the marine vessel;a steering wheel having a sensor that generates input signals corresponding to steered positions of the steering wheel;a control module in signal communication with the steering wheel that generates output signals based on the input signals; anda steering actuator in signal communication with the control module that moves the marine device to the desired steering angles in response to the output signals;wherein in response to initiation of a docking mode, the control module reduces a steering ratio between the input signals and the output signals, such that the steering ratio is less than the steering ratio would otherwise be were the marine vessel in a non-docking mode, and generates the output signals based on the input signals and the reduced steering ratio; andwherein the control module decreases a number of lock-to-lock turns of the steering wheel in response to initiation of the docking mode, such that the number of lock-to-lock turns is less than the number of lock-to-lock turns would otherwise be were the marine vessel in the non-docking mode. 13. The system of claim 12, wherein the control module brakes the steering wheel once the steering wheel has been rotated from a neutral, centered position by half the number of lock-to-lock turns. 14. The system of claim 13, wherein the steering wheel comprises a servo motor, and the control module sends a signal to the servo motor to prevent further turning of the steering wheel once the steering wheel has been rotated from the neutral, centered position by half the number of lock-to-lock turns. 15. The system of claim 12, wherein a memory of the control module contains a steering angle map that correlates the output signals to the input signals, and wherein the control module multiplies the output signals from the steering angle map by a predetermined multiplier in response to initiation of the docking mode, prior to sending the output signals to the steering actuator. 16. The system of claim 12, wherein a memory of the control module contains steering angle maps that correlate the output signals to the input signals, and wherein the control module selects a steering angle map incorporating the reduced steering ratio in response to initiation of the docking mode. 17. The system of claim 12, further comprising a docking mode selection switch configured to initiate the docking mode upon actuation by an operator. 18. The system of claim 12, wherein the steerable marine device is an outboard motor that incorporates the marine engine.
