Can anyone suggest what size electric outboard would be best for my canoe - 17' OT OTCA purchased new by me in 1962? I'm now just shy of 80 years old, and a 4 or 5 mile upstream paddle isn't as much fun as it used to be. Neither is an upwind paddle on the big lake, for that matter. I guess electrics are measured by pounds of thrust - not hp. What rating would be good for the canoe with two people? I don't want to challenge Miss Pepsi in a Gold Cup race, but I certaily don't want any of you young whippersnappers overtaking me while I'm motoring along at full thrust. Another motor I'm considering is an era-correct gas outboard - like a Martin 20, which is 2.5 hp and weighs about 30 pounds. Any advice on that potential choice?? Thanks Al D
