I recently purchased a 1997 18 ft Polar Kraft. The boat has a 50 hp 4 stroke that I believe is in the 2000 era. Today I decided to clean up the rat nest of wires and install a fuse block. As I worked on clearing wires that had been zip tied to the steering cable and outboard remote control I found a single green wire coming out of the rear of the remote control under the key ignition and kill switch. This wire was not hooked to anything on the other end. WHAT DOES THIS WIRE CONTROL AND SHOULD IT BE HOOKED TO POWER?.
