Re: black/yellow kill wire 1970 evinrude 115 hp ??
Black/yellow is not applicable to this motor. It has a Prestolite "Pulse Pack" CD system, powered by the boat battery. A somewhat complex system with a "safety circuit" to turn it on and avoid accidental starting. Anyway, bottom line is that it is killed by simply turning off the key which kills the voltage to the safety circuit (purple wire).
