I am adding a BBT dual mount at the bow of my 2002 classic and need some help. The BBT comes with a base plate that goes under the fiberglass for maximum support but I can’t reach that area to hold it in place. The base plate for the BBT mount is approx 4.75 inches in diameter. Can I cut a 5 inch hole under my ultrex foot pedal and still have plenty of support for the pedal? Also, I am not sure what is under the deck where the foot pedal is it what issues a large covered hole could cause. I plan to put a matching size hatch access cover over the hole when done. Any advice would be appreciated. Thanks
