I have a SN200 and the driver's seat will not slide. I cannot see anything in the rails nor does it appear that the rail is hitting a loose bolt, but admittedly it is difficult to see. Has anyone replaced one of these rails themselves? If it is an easy fix, I will do it myself and avoid having the boat sitting at the dealership waiting for them to get through their winterization work. If the repair is a PITA, I can let them do it.
