With your concerns for balance and stern weight, which I agree with by the way, I would highly recommend a Hermco bracket because they have the most flotation. Don said he can make them with various setbacks . . . 18", 24", 30". The 30" is nice if you're a diver, but otherwise you could use a shorter one, especially if you pick a V-4 motor. Also if you're boating in salt water, you won't have to worry about corrosion issues with it.
