Evinrude 175 2 cylinders not firing

Looking to find some thoughts on a direction to initially go with a Evinrude 175 2 stroke which is not firing on the 2 bottom cylinder of the port bank of the V? Swapped out the powerpack/ignition box from the other motor and still have the same problem. Same two cylinders not firing. Tends to indicate another issue than the ignition box. Im going to check the stator for output next. It doesn't seem that two cylinders on the same side would not be firing if a single component went bad as they are usually paired to the opposite side cylinder not the same side. Any thoughts or direction to head.

Are you saying you do not see spark on those 2 cylinders ?-------Or there is no change when plug lead is pulled ?-----------Checked compression ?--------Ckecked high speed orifice plug in carburetor ?

Actually the spark tester is indicating no spark in neither #5 or #6 cylinders. The compression is strong. Coils have been swapped as were the plug wires. Compression is good. Voltage to the coils effected is less than 2 volts. Doesn't appear to be fuel related as spark plugs are not getting spark from the coils. Other coils which are functioning and firing have more than double
