listen man this is what I did to my 14 ft aluminum. I took a 6 inch piece of 2x4 and put 2 bolts thru the wood and bottom right side of the transom with neoprene washers on both sides of the transom and secured the wood. then I screwed the transducer and temp guage to the block of wood, works like a charm. tight lines Ben
