Abstract
PURPOSE:To prevent the suction of external air and enable complete draining, by connecting the pump-side end of a suction passage with a drain port which is located under water when an outboard motor is tilted down and which is located below a pump when the motor is tilted up. CONSTITUTION:A water pump 23 is provided at the halfway part of the drive shaft of an outboard motor 1. Cooling water sucked into a suction passage 18 through a water inlet cover 21 having numerous water intake holes 22 is supplied to an engine through a water tube 82 and drained through a communication recess 19, a drain passage 37 and a drain port 38. The drain port 38 is placed in a fore position as to the direction of proceeding of the boat. The drain port 38 is submerged wen the outboard motor 1 is tilted down. For that reason, external air is not sucked through the drain port 38. When the outboard motor 1 is tilted up, the drain port 38 is located below the pump 23 so that water in the communication recess 19 and a pump chamber 26 is all drained through the port.
