Engine Room Access

[Bassman3]

Have a 2002 Sea Ray 420 Aft Cabin. The outboard sides of the engines (and fuel tanks) are inaccessible except by a squirrel. There are panels in the salon floor that are bolted and siliconed together that could be removed to access the engines. Has anyone performed a refit to make these panels more easily removable or have another idea to allow quick and easy(er) access to engine rooms?
