I have an 86 45hp merc with no spark on cylinder three. I switched the wires around and know it is not the ignition coil. The other problem is that I can start it and it runs at fast idle for about 45 seconds then dies instantly, i am pretty sure that this is not fuel related, but ran out of daylight to keep testing. I assume that this means a new switch box just wondering if there is something else I should be looking at.

If it is not the coil it musy be the switch box, for itm to run on the other cyls. the stator is good and the trigger is working--bob
