Sea hood came off using wedges, as suggested, and a cheap tool used to open paint cans. It was small enough to fit in the opening to assist the wedges. Thanks for the assistance!
Unfortunately, removing the sea hood did not give me access to the acrylic hatch slider stops. Violently pushing up on the back side of the slider while a second person pulled the hatch slider toward the stern freed the slider. Installed new acrylic panel pushing up and in. Don't know if this arrangement is common (Mine is a 33), but I would suggest trying the above approach first before removing the sea hood.
Thanks for the help.
