"For my 1978 Johnson 140hp. What type spark plug wire should I use?

I looked at the Sierra brand wires which were yellow in color, but heard they weren't copper core wires. Is it important that the wire be copper core wire for a 1978 motor?"
 
Yep go to any lawn mower repai

Yep go to any lawn mower repair shop and pick you up enough wire to make you up some wires. Solid core not graphit wires.
