Re: 1971 60hp Evinrude
71 60hp evinrude 3-cyl.Tried to disconnect black/yellow wire. Don't have that color, have black/white from amplifier, motor wouldn't fire. re-connected and engine started. Started each time until later in day, then wouldn't fire at all. Maybe its a bad amplifier again. some times it starts and others times it wont even with battery charged up fully.
