Just curious, was it Kevlar?
I agree, these are amazing responses. Thank you everyone.
In summary, I understand putting a outboard on a canoe is okay as long as it's built for it. My old kevlar likely is not. However a light electric motor would be a good option and somehow put the battery near the front to offset my weight in the back.
With a 30 or 36 lb thrust motor can I troll around all day? (battery life) Lake trout is right around the corner up here!
Thanks again everyone!
