Patti and Barry,
On my 22' cruiser I just put a fingernail under it and poop it out, it may take a putty knife to remove it the first time but after that it comes out with no trouble. I had water in the area last year and found that water was coming in at the port side clamshell area. The factory had not installed a drain tube and water would seep in from the outside in sloppy seas. It took a while to find the problem but I think I have it solved now.
