hello,has anyone changed out the factory foredeck hatch? I've just re-bedded the plastic but it's a lousy design on mine: just a flange that the plexi sits on with a small trough all the way around that you layup the goop. It's only a matter of (a short) time before the goop gives way again.I'd like to know if anyone's done a straight swap with some manufacturer's product so I don't have to drill more deck holes.Thanks!
