The essential compliment to the Padded Plastic Seat. Mounts to the frame under the seat and allows you to pivot around to access gear and trolling motors or cast off either side of the boat with ease. Will also work on the unpadded seat models. Swivel does not come with hardware you will need, 4 - 1/4"x13/4" bolts, 8 - 1/4" washers, 4 - 1/4" locking nuts to mount the swivel to the frame. If you are also purchasing the #844 7" Pedestal Riser YOU will also need to provide your own hardware to mount the swivel to the top of the pedestal, this would consist of 4 - 1/4"x1" bolts, 8 - 1/4" washers, and 4 - 1/4" locking nuts. These are available at any hardware store and should only cost a couple of dollars. When using a swivel and pedestal assembly, always mount the pedestal to the frame first, then mount the swivel to the underside of the seat, finally place the seat/swivel combo on top of the pedestal riser and secure with the necessary store-bought hardware.
