I just got my first boat,a 14' aluminum V. it's a 1970 Grumman. It came with an old Minnkota electric, but no gas motor. That's not to big a deal, since a lot of the local fishing holes are electric only or limited to 9.9 hp. I would like to get in the rivers eventualy, but for now i just want to get it in the water. Here is my question. Does anyone know if there is a comparison for how many lbs of thrust a given HP gas motor would put out? Any idea where I could find one? For example, would a 2hp gas motor equal a 40lb thrust electric? I had been considering the 5hp Briggs and Stratton outboard for the "larger" lakes or the river, but would I be better off with a med/large electric if it would put out similar thrust and be able to use it on more waters?
