I agree with Sloride, a modified Vee jon would be a better choice.
I too have used electric motors. They are a bit of a double edged sword though. They are quiet, BUT, the batteries are very heavy. It is possible to get a small gas outboard that is lighter than a trolling motor/battery combination.
Neither the gas or electric is perfect in all situations. I find the gas outboard is the most versitale. They can be used anywhere except places that don't allow them. They have greater range, provide more power, and can be lighter.
