I'm thinking about purchasing a 15 ft canoe to use for fly fishing the marshes on the coast. Since my budget isn't too steep on this project I'm thinking of building one of those mud motor kits to use temporarily. The boat only weighs 100 pounds, is pretty streamlined, only 42 inches wide at the widest point. How fast do you think a 6.5 hp long tail would push it? I know it will be a lot slower than an outboard, but I want to be able to get into the back areas that I wouldn't be able to reach with a regular motor. Before you say save the money and buy a real longtail, 2 grand is just out of the question right now. This kit and motor will cost me under 400 dollars, and if it works for a while and breaks, oh well. Thanks.
