Here the stuffing tube gets lined up to be 'glassed in after the motor mount holes are drilled. The kit comes pre-drilled on the #3 bulkhead for the stuffing tube but since I went with CY motor I had to slightly alter the height of the stuffing tube hole due to a casting difference on the bottom of the engine crankcase. No big deal as about 30 seconds with the Dremel tool took care of that.
