摘要： An outboard motor comprises a cowling, having a top cowling and a bottom cowling, that cooperate to define an engine compartment. An intake air duct draws outside air into the engine compartment. A water collecting part is arranged in the bottom cowling for accumulating water that may enter the cowling through the air duct. A water passage may also be provided for guiding water from the intake air duct to the water collecting part. The water passage may have air openings for allowing air to enter the engine compartment independent of the water. A floor of the engine compartment may be adapted to contain water splashing and direct water to a water collecting part.

摘要： A number of the embodiments of exhaust systems and oil tank arrangements for four-cycle internal combustion engine powered outboard motors. In all of the embodiments, idle exhaust gases are discharged to the atmosphere through a path that extends above the oil tank. A cooling jacket is formed around an exhaust pipe that depends through a cavity in the oil tank and coolant from this cooling jacket is discharged to the exterior surface of the exhaust pipe so as to cool it. Cooling water from the engine and from the exhaust pipe cooling jacket is isolated from the idle exhaust gas discharge so as to ensure that this cooling water cannot enter the engine through the idle exhaust gas discharge path.

摘要： 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.
