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.

Cowling and air inlet device for outboard motor

Two 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 open only on one or both sides of the cowling so as to insure adequate air induction to the engine but to prevent water from entering the interior of the cowling and the engine induction system. The air inlet is formed in a upper rear surface of the cowling and has formed therein an air intake duct for supplying air to the engine induction system. A cover is positioned above the air intake duct to cooperate in defining a flow path for air through the air inlet to the air intake duct and to prevent foreign objects from falling in the air intake duct.

A cowling and air intake device is provided for the powerhead of an outboard motor which includes an air intake duct with a downwardly facing opening. The duct is mounted within an air inlet cavity formed within an upper rear portion of the cowling. A cover is secured to the cowling to form the top surface of the air inlet and to cover the intake duct. The air inlet inducts air from the atmosphere through a rearwardly facing opening wherein the air is drawn up into the intake duct for supply to the induction system of the outboard motor's internal combustion engine. The downwardly facing intake duct insures that water will not enter into the interior of the cowling or into the engine induction system.
