Jump pump arrangement for jet boat

摘要

A water-removal assembly for removing accumulated water from the bilge of a hull of a watercraft that includes a jet propulsion unit with an impeller. The water-removal assembly includes a water pickup provided in the engine compartment. A means for removing water from the engine compartment and preventing water from entering and syphoning into the engine compartment is connected to the water filter by a first conduit. The conduit connects the water removing and preventing means to a water discharge point in the jet propulsion unit so that water is pumped from the bilge. The water removing and preventing means includes a check valve that allows water to flow in one direction so that water is prevented from entering the bilge. A weep hole is provided in the water removing and preventing means to prevent syphoning from occurring in the water-removal assembly.
