Abstract
An improved cowling arrangement for an outboard motor powered by an internal combustion engine. The improved arrangement includes a flywheel cover and cowling that incorporate upwardly and downwardly extending ribs which are positioned along an air path between the air vent of the outboard motor and the throttle body of the motor. These ribs act as labyrinth-type seals which prevent water entering the air vent from contacting the throttle body. Also disclosed is an improved cowling arrangement that prevents water pooled on the flywheel cover from draining onto the throttle body when the motor is tilted, such as when the watercraft banks into a turn.
