ABSTRACT:
A number of embodiments for removing bilge water from a jet powered watercraft without obstructing the flow through the jet propulsion unit. In all of the embodiments, a portion of the water pressurized by the jet propulsion unit is diverted through a venturi section and the reduced pressure at the throat of the venturi section is used for drawing the bilge water. In many of the embodiments, the bilge water discharge opening is located so that bubbles will appear to the operator when the watercraft is in an idling mode for indicating to the operator that the bilge has been cleared of water. In one embodiment, the bilge water is discharge into the exhaust system of the engine for aiding in exhaust cooling.
