I bought a trolling motor for my canoe, built a mount for it etc. Then I needed a trailer to haul it with the battery since it now weighs more than my old body can easily handle!
So, I got a kit for a small utility trailer from Harbor Freight. Nice kit, well designed, complete parts came with it, and the instructions were good. So I needed to make a longer hitch, add some hold down eye-bolts, and make something for the canoe to rest on. I also needed to mount the tail lights on the canoe itself since the back of it would sit a few feet back from the actual trailer. I mounted the lights on angle iron and clamped the angle iron to the motor mount. The lights have a separate trailer style electrical connection so it can be disconnected when launching.
Here's some pics for your viewing pleasure! 







Here is the battery box with a quick disconnect.

Here's the motor mounted. It rides inside the trailer when being towed. I rewired the motor with heavier gauge wire.
