i have a 85 merc 115 inline that loses spark to 1,3,5 off idle. It has spark on all 6 untill i touch the throttle then it bogs and drops the odd cylinders. I have been troubleshooting for about a week now with still no fix. Compression is 145-150 on all cylinders, changed switchboxes, tested all coils and wires, new plugs. could it be a stator problem? tested the trigger with an ohmeter and it was within specs. any help would be great because i am about to pull my hair out and i dont have much left to begin with!
