Abstract

An engine cooling system is provided with one or more flexible conduits attached to drain openings of the engine and its related components. First ends of the conduits are attached to the drain openings while the second ends are sealed by studs attached to a plate of a stationary bracket. A retainer is slidably associated with the flexible conduits and attached to a tether which is, in turn, attached to a handle. By manipulating the handle, the tether forces the retainer to slide along the flexible conduits and control the position of second ends of the flexible conduits. This allows the system to be moved from a first position with the second ends of the conduits above the first ends of the conduits to a second position with the second ends of the conduits below the first ends and in the bilge of the boat. The system allows an operator to stand in a single location and move the drain system from the first and second position and back again without having to reach down into the engine compartment to remove drain plugs. The system allows the cooling system to be easily drained or flushed.
