A watercraft has a water preclusion structure for internal ventilated cavities. A ventilation tube connects an internal cavity, such as an engine compartment, with the atmosphere for allowing air transfer to or from the cavity. A water preclusion structure is disposed between the atmosphere and the cavity. In one arrangement, water repellant filters are installed over an end of a tube that allows the air transfer. In another arrangement, an air box that communicates with the cavity contains air inlets that have water repellant filters disposed between the outlet of the air box and the inlet of the air box. The air box also contains a drain to allow water removed from the air to drain out of the air box.
