Buy two cheap used 12v motors and put them in series. That will take 24v and
you'd have the fastest canoe on the lake!!
On the more serious side, I would be more concerned about how long the speed
control on the trolling motor would last than I would the motor itself. How
robust is the over-voltage protection for the electronics in the speed
