Boat engine cooling system

Abstract

The boat engine cooling system provides cooling of the engine of a boat or other nautical vehicle through both chemical coolant, such as an antifreeze solution, and environmental water; i.e., the water the vehicle is passing through. In use, heated engine coolant is expelled by the engine and passes through a coolant inlet port formed through a hollow tank, where it is transported through a coolant pipe to the engine. Further, water from the environment (i.e., the lake, ocean or other body of water the vehicle is passing through) is injected into a cooling reservoir in the hollow tank through a water inlet port. The engine coolant passing through a central portion of the coolant pipe is cooled by the water in the cooling reservoir prior to circulating back through the engine.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 129,390, filed Jun. 23, 2008.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to inboard motors for boats, and particularly to a boat engine cooling system for an inboard motor.[0004]2. Description of the Related Art[0005]Typical inboard boat motors operate at temperatures of approximately 180° F. It is well known in the art to use the environmental water (i.e., the water of the lake, ocean or other body of water the boat is traveling in) to cool the engine, with this water being passed into or around the engine in a conventional manner.[0006]However, such systems rely on pure water for the cooling of the engine. Due to contaminants, such as chemical pollutants, as well as natural marine life, filter systems must be used before the water is passed to the engine. Such filters must be changed regularly, can easi...

Problems solved by technology

However, such systems rely on pure water for the cooling of the engine.

Such filters must be changed regularly, can easily become clogged, and are not 100% effective, thus resulting in clogged engines, broken blocks and the like, which must be fixed or replaced.

Further, environmental laws of some jurisdictions have required this type of system to be banned, since the water passing through the engine and back into the environment may be contaminated by the engine.
