Hey gang, just bought a car topper "Jon Boat" for the wife and I

It is a 10 footer aluminum, and in great shape. I was wondering, now, a trolling motor to put on er. I am using it for city fishing, just me and the wife, and our gear. Rods, cooler, battery and motor. Now looking around, I'd like 40lbs of thrust. The "Endura C2 " or the Endura Max, price difference is minor, but was looking for feedback, and maybe set up ideas, for I've never done this on a small craft before. Any help is awesome gang!!!
