WHAT? The furrel side isn'nt square it is round for a 3/16"shaft or 1/4" shaft. I asked because the motor you have I would use the 3/16" shaft because you have more prop options. You need more than just a flex shaft and brass furrel to complete the change over. You cut the cable to length you need and silver solder on the brass furrel. The brass furrel has set screws to hold the end of the prop shaft and flex cable together.
