The gas engine is much faster than the electric trolling motor. I bought them both the same weekend. On test runs putting in Landers and heading upstream with the Potomac at 4' at PoR, I made it to the cut over for the big island in 45 minutes with the trolling motor and completely exhausted the battery. I bottomed out on a rock and fished a while. When the battery had sufficiently recovered from the high output, I went back to the ramp. With the gas engine, it took 8 minutes with the engine running barely above idle.
I will take my canoe into cold water, but only with people with whom I've paddled before and have the right clothing for it. I have what amounts to a two piece dry suit and would insist on anyone coming with me to be similarly equipped. There are other cold water safety items I'd have along. I also am very careful about what water I'll fish or paddle in cold water situations. Most likely I'd take my raft, which is much more stable even than my huge canoe, but it won't take the gas engine on it. It's awfully slow going up-current, but it will go. Being able to sit in a comfy chair on the rowing frame and sipping coffee while I motor upstream sure beats having to paddle vigorously upstream for two miles like I used to do from Brunswick to get to Knoxville in the early mornings.
