ABSTRACT:
The outboard motor includes an engine driving a propeller. The engine cover includes an upper dome-like cover sealingly connected to a lower pan-like cover. A combustion air opening through the upper portion of said upper cover has a partition inside the opening requiring entering air to travel upwardly into a chamber between a baffle between the inside of the upper cover and the cover. The baffle includes a portion cooperating with the cover to define a downwardly directed duct leading air towards said lower cover clear of the engine. The engine draws combustion air from the region of the lower pan to a higher elevation at the front of the cover while entrained water is deposited in the lower cover a pump discharges the water.
