Embodiment Construction

[0014]The boat engine cooling system 10 provides cooling of the engine 16 of a boat or other nautical craft through injection of both chemical engine coolant, such as antifreeze, and environmental water; i.e., the water the boat is passing through. The boat engine cooling system is preferably applied to an inboard engine 16. It should be understood that the system 10 and engine 16 shown in the sole drawing FIGURE may be used with any type of marine propulsion system, whether an inboard or outboard engine.

[0015]The boat engine cooling system 10 includes a hollow tank 14. As shown in the drawing, the hollow tank 14 defines a reservoir. Hollow tank 14 is mounted within or on the boat and is connected to the boat engine 16, as will be described below in greater detail. An engine coolant inlet port 24, an engine coolant outlet port 30, a water inlet port 36 and a pair of water outlet ports 41, 42 are all formed through an outer wall 15 of the hollow tank 14. A pressure relief port 32 may...

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...
