Hi jeffH,
I can't help you much on the motor mounts -these days I prefer for easyness the MFA motors c/w with brackets for the sake of a pound or two on the cost of a motor -its seems a no-brainer to me.
For drilling the hull I'm not sure what you're struggling with, obviously the shafts form an angle to the hull so it's not a round hole so you don't drill at te shaft angle. You should really do the normal and apply good quality msking tape to the hull, transfer the dimensions and then start cutting the "oval" hole shape using multiple small drill bits then join up the holes and -use your imagination, some coarse paper wrapped round a dowel or tube smaller than the prop shaft which you CAN probably get near enough the right angle, then file and sand to suit until the hole is good enough, or you are happy to fill the gaps with resin and filler. A mini-drill helps as it has higher speed and you can drill many small holes and join up with a blade, or sometimes just the drill bit if you're careful. I also often use a "reamer" on grp mouldings -but filing and sanding works as well.
