I am about to install a new seat base for a Millenium seat mounted on a pedestal. This will be the driver seat in a tiller operated Lund. The floor has carpet over a 3/4" plywood floor. What is the most secure method of attaching a 9" base that fits flat on the floor without a center hole. Originally the seat sat on a storage box attached to a side box area filled with floatation. I removed the storage box to allow more room in the stern for gas and battery.
Thanks
