I made my mount to hold my motor while trailering my 170. I used a piece of galvanized "U" channel and added a piece of wood to the inside giving me the same thickness as the boat motor mount. I made a nest at the bottom from 4" PVC and a galvanized bracket. I made the top bracket big enough to hold a gas outboard if I ever decide that I'd like to try one. Now to make the fixture to hold the rudder and tiller in the boat while trailering.
