I had the same issue for my cougar. What I did was make an oak wood square base about 3 x 7 x 3/4 inches ogeed th top edges, finised witha polyurethane clear coat, 3 coats, screwed to the boat using the old holes and then screwed the RAM to the oak with 3/4″ stainless panhead sheet metal screws. Looks really custom and no new holes Irv
