Have 1987 3270 motoryacht with aq225 305 gm engine that won't start. Had it running, turned it off and now won't start. Changed plugs, points, cap, wires and rebuilt the carb ( it was due) changed fuel filters, yes it does have gas. Jumped from coil plus to battery still no start. Tried starting fluid still nothing, convinced it is electrical. Put a spark tester on both coil and plug lead got spark to 3 no problem except color was yellow, definately not a good strong blue. Looking for any help or suggestions.
Thanks in advance. Mike
