A siphon inhibiting valve is provided for a marine engine cooling system. The purpose of the valve is to prevent the draining of the pump and outboard drive unit from creating a siphon effect that draws water from portions of the cooling system where heat producing components exists. The valve also allows intentional draining of the system when the vessel operator desires to accomplish this function. The valve incorporates a ball that is captivated within a cavity. If the ball is lighter than water, its buoyancy assists in the operation of the valve.

1. A marine engine cooling system, comprising:a pump; a heat producing component; a conduit connected between said pump and said heat producing component; a valve connected in fluid communication with said conduit between said pump and said heat producing component; a ball disposed within a cavity of said valve, said valve having a first port and a second port, said valve being configured to receive a stream of water into said first port from said pump and pass said stream of water serially through said cavity and said second port to said heat producing component; and a seal, responsive to movement of said ball within said cavity, between said first port and said cavity to inhibit water flow through said cavity toward said pump, said valve being positioned to dispose said first port above said second port.
