Hey guys, I have a Z518 intercoastal. Has SeaDek on it. On the front deck there is spot that looks like it would be for a Recessed TM tray. Looking through the compartment behind the bow seat it just looks like a tub. How do I get inside of this thing. On the front deck it almost looks like it could be a compartment lid. Is there screws underneath the SeaDek or is this thing glued in? Thanks in advance. I will attempt to attactch a pic.
