Coil question, most all of the 70-80 3 and 4 cyl. ignition coils seem to be the same size and same specs.. Although wire lengths might be different. Are they interchangeable as long as the wires are long enough? Why is my 1976 coil so much more expensive? Could I use a coil from a 1975 135hp Evinrude...
