" I have a pair of 1989 merc 150's. One is losing the spark on one bank of cylinders when the motor is loaded or rpm is increased. I have swapped stator, trigger, coils and plugs with the other motor which runs fine. I have also replaced the switch boxes and disconnected the rectifiers to try. No luck yet. Could I have lost another stator? I swapped parts one at a time trying to isolate the problem. "
