I am thinking of changing the seat position on my Searay 180 bowrider. I am tall and the position is too tight. There are several screws and a front stud with a nut. Has anyone worked on this arrangement before? I believe the stud has a head on it under the deck because it gets real tight when trying to remove. But if that is the case, I don't know how anyone put it there.<br /><br />How can I relocate?
