ABSTRACT:
An outboard motor has a cowling for enclosing an engine. Air inlet openings are formed in the cowling. An air intake chamber connects the air inlet openings and an air intake duct. Air that flows through the air inlet openings passes through the air intake chamber to the air intake duct. The air is then introduced into the engine. A front wall of the air intake chamber has a center portion positioned rearwardly of outer portions of the front wall. The air intake duct is positioned rearwardly of the front wall of the air intake chamber. The air inlet openings are positioned on both sides of the air intake duct. A rear wall is positioned rearwardly of the air intake duct. Each of the air inlet openings extends from the rear wall to one of the outer ends of the front wall of the air intake chamber.
