Abstract
Boat bailing apparatus for removing water from the interior of a boat comprising: a tubular housing adapted for attachment to the transom of the boat providing a passage through which fluid may pass from the interior of the boat to the exterior thereof; an annular seat near one end of the housing; and a ball closure carried within the housing for movement between a position engaging the seat, preventing fluid flow through the passage, and positions not engaging the seat, permitting fluid flow. A cage assembly may be provided within the housing to confine the ball closure for limited axial movement in the housing passage.
