Abstract

A remote control device for an outboard motor including a remotely positioned controller device that operates control devices carried by the outboard motor through optical fiber transmitted signals. The optical fibers are detachably connected to the controllers so as to permit removal of the controller. In addition, the controller is detachably supported within the associated watercraft so that it may be conveniently removed.

Claims

1. A system for anti-theft protection in a remote control mechanism for a marine outboard drive comprising a spark-ignited internal combustion engine and having a control element moveable between at least two different positions for effecting a control of said outboard drive, a remotely positioned controller adapted to be positioned remotely from said outboard drive and in proximity to an operator, a controller element carried by said remotely positioned controller and selected from one of a group of similar controller elements, drive means for operating said control element between its positions, optical fiber means for transmitting a control signal nonmechanically from said controller element and to said drive means for operating said drive means to actuate said control element upon operator actuation of said controller element, and means for detachably connecting said optical fiber means to one of said controller elements and said drive means, and unique encoding means for each of the group of similar controller elements for converting input signals from said controller element to unique optical signals for transmission by said optical fiber means and for converting optical signals transmitted from said optical fiber means to signals for operating said drive means.

2. A remote control mechanism as set forth in claim 1 wherein the means for transmitting the control signal comprises an electrical to optical converter for transmitting electrical signals to optical signals and optical signals to electrical signals.

3. A remote control mechanism as set forth in claim 2 wherein the electrical to optical converters are detachably connected to the respective controller and controlled devices.

4. A remote control mechanism as set forth in claim 1 wherein there are a plurality of control elements each operated by respective drive means and the remotely positioned controller includes a plurality of controller elements, one for each of said drive means.

5. A remote control mechanism as set forth in claim 4 further including condition indicators associated with the remotely positioned controller for indicating the condition of certain functions of the outboard drive.

6. A remote control mechanism as set forth in claim 5 wherein the means for transmitting the control signal comprises an electrical to optical converter for transmitting electrical signals to optical signals and optical signals to electrical signals.

7. A remote control mechanism as set forth in claim 6 wherein the electrical to optical converters are detachably connected to the respective controller and controlled devices.

8. A remote control mechanism as set forth in claim 7 in combination with a water craft having a console positioned in proximity to the operator and adapted to detachably support the controller for removal of said controller from the water craft upon detachable connection of said controller from said optical fiber means.
