AI Technical Summary

Benefits of technology

"The invention is a flushing system for marine propulsion systems that is simple and versatile. It allows for a convenient and easy to use method for flushing the engine. The system uses a flushing port or an automatic system that maintains backpressure to keep the engine cool and lubricated during the flushing process. The system can be used with different types of flushing fluids and can compensate for inadequate fluid flow or operator error. The system is designed to be used on outboards with seawater pumps and can be easily installed and maintained. Overall, the invention provides a reliable and effective solution for flushing marine propulsion systems."

Problems solved by technology

The “earmuff” style flushers will work in almost any circumstance if used correctly; however, they are difficult to work with, are subject to falling off or being pulled away from the intakes during flushing, and are potentially dangerous due to their proximity to the propellers.
The flush port connections are much more accessible; however, if the water supply volume and / or pressure is not high enough, or drops in the middle of the flushing cycle, the impeller water pump will run dry be ruined.
Another problem with trying to use flush ports is that the pressure needed to force water through the impeller pump varies dramatically with the size of the impeller pump.

Embodiment Construction

[0026]FIG. 1 shows the general layout of an outboard, OB, marine motor 2. A typical OB has a water intake 18 for taking in cooling water for the engine. The water pump 12 pumps the cooling water to the engine 5, and after it has gone through the engine 5, the discharged water 22 is sent back out to the body of water that it came from.

[0027] After the OB motor 2 has been used, it is a good and recommended practice to flush the engine 5 as well as other cooling system components such as the intake 18, the pump 12, inlet passageway 20, and the discharge passageway 22. Many OB motors 2 have an access port 15 for attaching a hose that is used to deliver clean water to flush the OB motor 2 after use. To help flush the OB motor 2, the flushing system 10 can be installed either before the engine 5, 10a, or after the engine 5, 10b, depending upon how the flushing system 10 is going to fit in with the OB motor 2 design.

Abstract

A simplified flushing system for marine engines. The flushing system uses a pressure regulating system to supply the engine with the necessary fluid needed for flushing and cooling as well as supplying the seawater pump with enough fluid to keep it cool and lubricated.

Description

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION [0001] This invention relates to a novel, yet simple system and process for flushing outboard marine propulsion systems with a desired fluid. This flushing system and process allows a person to quickly and easily flush an engine with or without the engine running and with the vessel in or out of the water. [0002] The need for such a system is commonly seen with marine engines. When a marine engine is operated, in fresh water or salt water, impurities in the water can cause cooling problems and corrosion of components if not properly flushed. Debris of various types can be picked up in lakes and rivers, and even the cleanest ocean water is going to have salt in it. Therefore, it is imperative that marine engines get flushed after every use. [0003] The difficulty is that flushing marine engines can be very cumbersome since the intake for cooling fluids is in the outdrive near the propeller. To flush an engine like this, the vessel's o...
