  • Patent number: 4571193
    Abstract: Two embodiments of improved cowling arrangements for an outboard motor that ducts inlet air to the motor without restricting the air flow and while at the same time insuring against water separation. In each embodiment, the cowling member includes both a rearwardly disposed air inlet opening and a sidewardly disposed air inlet opening. The sidewardly disposed air inlet opening is positioned so as to permit drainage of water from the air inlet when the motor is tilted up. In one embodiment of the invention, the sidewardly disposed air inlet openings are positioned at the forwardmost edge of a air inlet chamber so that water can drain from the air inlet when the motor is tilted up without any accumulation.

  • Patent number: 4379702
    Abstract: An intake duct for an outboard engine. A cowling atop the engine forms, with a top cover plate, a recess which opens rearwardly. Intake parts are formed at the right and left sides of this recess, near the upper elevation thereof, in the vicinity of the cover plate. This provides for air flow in such a way as tends to remove, in the recess, water which is entrained in the air stream, before the air flows out of the intake ports to the engine.
