I got it. Took a flat head screwdriver, a rubber mallet and tapped the screwdriver into the little indent on the back of the cover and slowly worked it up. It doesn't exactly just pop right off.On my boat, it would be best to go behind the gunwale and push outward. If I spent some time looking, once the screws were out, it's possible that a longer screwdriver or something could be used to pry or pull from outside (not sure).
