Abstract
The propeller shaft fairing is U-shaped in vertical section, and is partitioned to provide two separate sea chests from which water may be drawn for engine cooling purposes. The wall of the fairing in the region of the foremost sea chest is slot-wise apertured parallel to the propeller shaft and adjacent to the uprising side of the shaft when it is rotating to propel the craft forwardly, whereupon water is both rammed and pumped into the forward sea chest. The wall of the fairing in the region of the rearmost sea chest is apertured so that when the craft is moving in reverse water is rammed thereinto. Thus, under all conditions an adequate source of cooling water is available via at least one of the sea chests. The cooling water pump intake conduit includes separate branches drawing from the sea chests, and these branches are valve controlled automatically by means of the craft's operating control system.
