pic from the motor well side. bolted red oak recessed stainless bolts cut out recessed circles with a hole saw and then used a wood chisel to remove wood so the round part of the dink motors clamp sits in the round recess. The little sucker 2.5 Yamaha 37 pounds rode here on our portion of the Maine Cruise never moved. Note snap on the plate reinstalled for the rear curtain for our camper top.Now through bolted to prevent any movement and to prevent motor from being taken by just lifting off bracket.
