Abstract
Three embodiments of a cowling and air inlet device for a power head of an outboard motor are disclosed and described which include an air inlet formed in an upper rear surface of the cowling and an air intake duct formed within the air inlet for supplying air to the engine induction system. Various arrangements of partitions are provided within the air inlet for permitting adequate air flow to the engine induction system but preventing water from entering the interior of the cowling and engine induction system. A cover portion which may be separate or part of the upper surface of the cowling is positioned above the air intake duct and at least a portion of the cover is higher than the upper surface of the cowling. This cover portion also has at least one opening therein for permitting air from the atmosphere to enter the air inlet. These cowling and air device arrangements provide a sufficiently large space between the top of the air intake duct and the cover portion to reduce noise resulting from the flow of air around the top of the air intake duct.
