I have a Tyboo designed stainless steel kicker mount that was just fabricated up along with a 10" x10" x2" mounting board. The board is made up of two pieces of 3/4" Decraguard with a 1/2" marine center ply, all of the edge ply is epoxy sealed and the board painted.
Never been mounted on a transom. I was going to use it on my 16', but plans changed and I'm going to go with just the single main. I thought I'd make it available if one of the Brat's is looking for a great bracket.
I'd post some pics, but that is way beyond my pay
grade, but I would e-mail pics to anyone interested.
