I have a 2010 Triton aluminum jon boat and want to mount a 45lb Motorguide trolling motor on the bow. My problem is that the bow platform is continuous across the boat and has a skirt that extends down almost to the floor of the boat aft. Under the aluminum platform is a foam block that I assume was put there to add upright flotation. My problem is how to mount the base of the trolling motor as there seems to be no way to insert bolts through the deck and get washers and nuts on the other side. I have entertained the thought of using largish sheet metal screws but it seems as if they might vibrate out. Also, maybe a plywood base an inch thick screwed and epoxied to the aluminum? Anyone have a solution or advice? Thanks
