Abstract
PURPOSE: To prevent the water-intrusion to the engine part by arranging a valve means which is operated by the water having intruded and closes an exhaust passage, inside the exhaust passage.
CONSTITUTION: When an outboard motor is in the state of stop or advance, a floating ball 11 floats on the water surface at the normal level L of an exhaust pipe 7 or is suspended by a chain 10. In the state of retreat, the water around a screw 4 flows into from a screw fitting hole 8 and intrudes into the inside of the exhaust pipe 7, due to the reversal of the screw 4. At this time, the floating ball 11 is floated up by the buoyancy as shown in the dotted line, and contacted with the sealing surface 12 at the upper part of the exhaust pipe 7. Thus, an exhaust passage 5 is closed, and the intrusion of water into the engine part of the outboard motor and also the inundation of catalysts 9 can be prevented.
