Re: 1983 johnson 60 hp. will not turn off
the kill circuit is the black wire w/yellow tracer leading from the powerpack. Connecting this wire to ground shorts the ignition, shutting off the engine.
Follow this wire from the powerpack, you'll come to a plug...unplug it, make sure it's clean & free from corrosion, making a good connection inside the plug, etc. You may have to push the pin and socket out of the connectors, make sure that connection is good.
In any case, that wire has a fault in it somewhere, look for any place where it might be pinched or bent, where it might break inside the insulation.
