I had an aluminum bracket that fastened to the gunnels and had a vertical 1/2″ aluminum mounting plate for the motor. After putting it on the back end, I came to the conclusion there had to be a more comfortable way. I put the bracket on the front end and used the canoe backwards. I sat on what was normally the front seat and a friend could use a hang-on seat on the other end. It worked great.
BE SURE TO FASTEN THE BATTERY DOWN. My kids thought tipping the canoe to scare each other was great fun. Before I got them to stop, they tipped far enough to make a group 27 battery slide to one side, generated enough momentum to cause my tackle box to slide also and over we went. Fortunately we were in shallow water, recovered everything, and started swimming before we got to the sandbar where we were planning to swim anyway.
