yeah, a 33" bottom is wide. Heck, a 1436 jonboat is only about 30" at the bottom. The height of your sides is a big factor too. A canoe feels safe to me because of the relatively high sides compared to a pirogue or jon.
I used to run a 55lb minnkota on my canoes. It couldn't touch the power a 1.5 evinrude mate put out. And by the time you add the weight of a battery, the outboard ended up weighing less than half what the trolling motor did. Even my 3.5hp only weighs 30lbs or so plus fuel. And it'll push 2 people 9mph on a hog-backed square stern. But foot-steering is much easier to DIY on a trolling motor. I had a Creek Boat that was set up with foot pedals and a knob by the seat to control power. If that boat hadn't weighed over a hundred pounds, I'd still have it. Neat for trolling around pan fishing and duck hunting small creeks.
