Abstract
A fluid draining device for an outboard motor is provided with a conduit through which exhaust gases are directed. The flow of exhaust gas through the conduit induces a lowered pressure in a central portion of the structure. The reduced pressure magnitude in the central portion of the structure causes a pressure differential in a drain tube that is sufficient to induce a flow of water through the drain tube from a region to be drained toward the central portion. The device uses the venturi effect to create the lowered pressure. The exhaust gas flow is directly through the conduit from an idle relief exhaust passage to an exhaust port from which the exhaust exits from the marine propulsion system.
