A system (40, 80) for inhibiting marine growth or other fouling in a cavity (26) of a watercraft (20) which is at least partially submersed when the watercraft (20) is sitting in water. The system (40, 80) comprising a cover (41, 81) for sealing an opening (31, 32, 73) of the cavity (26) such that water is inhibited from entering the cavity (26) through the opening (31, 32, 73), and such that a displacing fluid that is introduced in to the cavity (26) and that displaces water from the cavity (26) is inhibited from escaping from the cavity (26) through the opening (31, 32, 73).
