You want to make backer plates for the inside of mounting points . I used 1/2” ply about 5x8” basically biggest i could fit in mounting locations. Used fiberglass reinforced filler to fill the void between ply and hull. 3 years on nocracks. 12 hrs seems high for a shop, my dad and i did it in about 4-5 hrs , would think if you do it regularly would be quicker…Thanks, Jayhawk!
I did find a dealer willing to install the tower. They said the last quote they had was $1,800 to install. Took them 12 hours of labor. I was hoping to save the cash and do it myself. Besides a drill, drill bits, tape, and sockets/wrenches what else do I need to buy to properly prepare the holes?
