A watercraft control system for a watercraft having multiple control stations routes operation control signals in a non-competing, non-contradictory manner. In an embodiment, the control system includes a plurality of links. When abnormalities affect one or more of the communication links, the control system maintains communication through one or more of the unaffected communication links.

What is claimed is: 1. A watercraft control system for controlling a watercraft having a motor and having multiple control stations, the watercraft control system comprising: a first control station comprising: at least one memory that stores authorization information designating whether the first control station is authorized to control the watercraft; and a first set of operational controls that output one or more operational control signals when the first control station is authorized to control the watercraft; a second control station comprising: at least one memory that stores authorization information designating whether the second control station is authorized to control the watercraft; and a second set of operational controls that output one or more operational control signals when the second control station is authorized to control the watercraft; and and a motor controller that receives operational control signals from the authorized one of the first control station and the second control station and that controls the motor in response to the operational control signals. 2. The watercraft control system of claim 1, wherein, when the authorization information stored in the at least one memory of the second control station designates authority for the first control station to operate the watercraft, the second control station disables the output of the one or more operational control signals of the second set of operational controls. 3. The watercraft control system of claim 1, wherein, when the authorization information stored in the at least one memory of the first control station designates authority for the second control station to operate the watercraft, the first control station disables the output of the one or more operational control signals of the first set of operational controls. 4. The watercraft control system of claim 1, wherein the first set of operational controls includes a start/stop control. 5. The watercraft control system of claim 1, wherein the first set of operational controls includes a throttle/shift control. 6. The watercraft control system of claim 1, wherein the first set of operational controls includes a steering control. 7. The watercraft control system of claim 1, further comprising: a first communication link that provides communication of the operational control signals of the controls of the control stations; and a second communication link that provides communication of the operational control signals of the controls of the control stations. 8. The watercraft control system of claim 7, wherein when at least one operational control in the first set of operational controls receives an abnormal signal via the first communication link and switches communication to the second communication link in response to the receipt of the abnormal signal. 9. A watercraft motor control system that routes communication around improperly operating communication links in a watercraft having a motor, the watercraft control system comprising: a first set of controls that outputs signals; an electronic control unit (ECU) in the motor, the ECU receiving the signals and controlling the motor in response to the signals; a first communication link that couples the signals from the first set of controls to the ECU during normal communication conditions; and a second communication link that selectively couples the signals from the first set of controls to the ECU when a control in the first set of controls determines that communication to or from the ECU via the first communication link is abnormal and switches communication to the second communication link. 10. The watercraft control system of claim 9, wherein communication via the first communication link is between the first set of controls. 11. The watercraft control system of claim 9, wherein the first communication link comprises a bus network. 12. The watercraft control system of claim 9, wherein communication via the second communication link is among the first set of controls. 13. The watercraft control system of claim 9, wherein the second communication link comprises a local bus network and a secondary bus network. 14. The watercraft control system of claim 9, wherein the first set of controls includes at least one memory that stores routing information. 15. The watercraft control system of claim 14, wherein the routing information includes routing instructions when communication is normal and routing instructions for when communication is abnormal. 16. The watercraft control system of claim 10, further comprising a second set of controls that communicate with the ECU via the first communication link or via the second communication link. 17. The watercraft control system of claim 16, further comprising at least one memory that stores authorization information to designate either the first set of controls or the second set of controls as being authorized to communicate signals to operate the watercraft. 18. A method of authorizing one of a plurality of sets of controls for a watercraft having a first control station and a second control station, the method comprising: receiving electronic data identifying one of the plurality of sets of controls authorized to operate a watercraft; storing the data; determining, based on the stored data, whether a received operation control signal from the plurality of sets of controls is from the authorized one of the plurality of sets of controls; and operating the watercraft when the received operation control signal corresponds with the authorized one of the plurality of sets of controls. 19. A watercraft control system for routing communication, the system comprising: a watercraft operational control coupled to two or more communication links; and a memory that identifies one of the two or more communications links as active when an abnormality is detected in another of the two or more communication links. 20. A method for routing communication in a watercraft control system, the method comprising: detecting an abnormality in a first communication link coupled to one or more watercraft controls; storing information indicating that an abnormality has occurred in the first communication link; and routing communication to a second communication link on the basis of the information.
