I hav a mid 80s yamaha 115 b4 runs great great compression and everything except u dnt know whether or not it will start depending on the day and time. I can use the boat all day and the next morning it will hav no spark. But if I leave and come back crank it over it will fire right up Jst currious on what I could be. Iv messed with the harnesses and wires also bi passed the kill switch and that doesn't affect anything it has spark when it wants to? What could this be thanx Ryan
