  • Patent number: 5967200
    Abstract: A fluid catch bag sized and configured for placement below an engine, and particularly an inboard engine on a boat, includes a floor, side walls and end walls formed of a flexible, liquid impervious material and surrounding an interior fluid collection chamber. The upper peripheral edge zones of the side walls and end walls are provided with eyelets for attaching the catch bag in operative position below the engine so that the walls extend generally vertically and upwardly from the floor in surrounding relation to the engine. A collapsible bladder interconnects in fluid flow communication with a lower portion of the collection chamber for containing the engine fluids which drip into the catch bag. A shut-off valve allows for disconnection of the bladder in order to dispose of the fluid contents contained therein, while preventing fluids within the chamber of the catch bag from spilling when the bladder is disconnected.
