A pneumatically operated valve is provided for use in conjunction with a seacock, or in place of a seacock, so that flow of water through the hull of a marine vessel can be blocked more easily than by manually manipulating the lever of a standard seacock. A controller is provided at a convenient location so that the operator of a marine vessel can pressurize a pressure line which closes the pneumatically operated valve and blocks water flow through the seacock. A spring return can be used so that the pneumatically operated valve is urged toward an open position when pressure is not provided by the operator of the marine vessel. In certain embodiments, sensors can be provided so that an ignition system can not be actuated when the pneumatically operated valve of the present invention is in a closed position.

1. A water management system for a marine vessel, comprising:a water conduit which is connectable in fluid communication with a fluid passage extending through a hull of said marine vessel;a pressure actuated valve disposed in fluid communication with said water conduit;a controller connected in fluid communication with said pressure actuated valve; anda pressure conduit connected in fluid communication between said pressure actuated valve and said controller, said controller having an inlet for introducing pressure into said pressure conduit, said controller comprising an internal manifold connected in fluid communication with said pressure conduit and a pressure indicator for indicating a change in pressure within said pressure conduit. 2. The system of claim 1, further comprising:an engine having an internal cooling system within a block of said engine, said water conduit being connected in fluid communication with said internal cooling system. 3. The system of claim 1, wherein:said pressure actuated valve is a seacock. 4. The system of claim 1, further comprising:a seacock connected in serial fluid communication with said pressure actuated valve. 5. The system of claim 1, wherein:said pressure actuated valve is a pneumatically controlled valve. 6. The system of claim 1, wherein:said source of pressure is a manually operated pump. 7. The system of claim 1, further comprising:a source of pressure connected in fluid communication with said controller. 8. The system of claim 1, further comprising:a pressure relief mechanism connected in fluid communication with said controller. 9. The system of claim 8, wherein:said pressure relief mechanism is manually actuated to relieve pressure within said controller and said pressure conduit to deactivate said pressure actuated valve. 10. The system of claim 1, further comprising:a cooling water manifold having internal passages and connected in fluid communication with said internal cooling system within said block of said engine, said cooling water manifold being disposed below the level of the lowest portion of said internal cooling system which normally retains cooling water when said engine is not operating. 11. The system of claim 1, wherein:said pressure activated valve comprises a pneumatic piston which is alternatively movable to a first position which prevents flow through said water conduit and a second position which allows flow through said water conduit. 12. A water management system for a marine vessel, comprising:a water conduit which is connectable in fluid communication with a fluid passage extending through a hull of said marine vessel;a pneumatically controlled valve disposed in fluid communication with said water conduit;a controller connected in fluid communication with said pneumatically controlled valve, a source of pressure being connectable in fluid communication with said controller;a pressure conduit connected in fluid communication between said pneumatically controlled valve and said controller, said controller having an inlet for introducing pressure into said pressure conduit; anda pressure relief mechanism connected in fluid communication with said controller, said pressure relief mechanism being manually actuated to relieve pressure within said controller and said pressure conduit to deactivate said pneumatically controlled valve. 13. The system of claim 12, wherein:said controller comprises an internal manifold connected in fluid communication with said pressure conduit and a pressure indicator for indicating a change in pressure within said pressure conduit. 14. The system of claim 13, wherein:said source of pressure is a manually operated pump. 15. The system of claim 13, further comprising:an engine having an internal cooling system within a block of said engine, said water conduit being connected in fluid communication with said internal cooling system; anda cooling water manifold having internal passages and connected in fluid communication with sai d internal cooling system within said block of said engine, said cooling water manifold being disposed below the level of the lowest portion of said internal cooling system which normally retains cooling water when said engine is not operating. 16. The system of claim 15, wherein:said pressure activated valve comprises a pneumatic piston which is alternatively movable to a first position which prevents flow through said water conduit and a second position which allows flow through said water conduit. 17. A water management system for a marine vessel, comprising:a water conduit which is connectable in fluid communication with a fluid passage extending through a hull of said marine vessel;a pneumatically controlled valve disposed in fluid communication with said water conduit;a controller connected in fluid communication with said pneumatically controlled valve, a source of pressure being connectable in fluid communication with said controller;a pressure conduit connected in fluid communication between said pneumatically controlled valve and said controller, said controller having an inlet for introducing pressure into said pressure conduit;a pressure relief mechanism connected in fluid communication with said controller, said pressure relief mechanism being manually actuated to relieve pressure within said controller and said pressure conduit to deactivate said pneumatically controlled valve; an engine having an internal cooling system within a block of said engine, said water conduit being connected in fluid communication with said internal cooling system; anda cooling water manifold having internal passages and connected in fluid communication with said internal cooling system within said block of said engine, said cooling water manifold being disposed below the level of the lowest portion of said internal cooling system which normally retains cooling water when said engine is not operating. 18. The system of claim 17, wherein:said controller comprises an internal manifold connected in fluid communication with said pressure conduit and a pressure indicator for indicating a change in pressure within said pressure conduit. 19. The system of claim 18, wherein:said pressure activated valve comprises a pneumatic piston which is alternatively movable to a first position which prevents flow through said water conduit and a second position which allows flow through said water conduit.
