"I have had this problem befor

"I have had this problem before when i bought the boat 5yrs. ago. i replaced the switchbox and the problem was solved. Now about 2 months ago i was leaving the lake and the same thing happened again, cylinder 6 was not firing. I changed coils and wires and figured is was the switch box again. $200 later and when i put the new switchbox on it did the same thing with in 2 min. everything checks out fine, (i.e stator, trigger,coil) just put new reetifier( it showd no continuity. what is taking out the swithbox on cylinder 6?"
