Abstract
This is a system and procedure that uses either a hand pump system or an electric pump system to drain fresh water or sea water out of a marine engine, and then uses either the hand pump system or the electric pump system to install fresh water or other liquid chemicals into the marine engine, and also use either the hand pump system or the electric pump system to recover the liquid chemicals from the marine engine.
Description
ELECTRICALLY POWERED MARINE ENGINE WINTERIZING
SYSTEM
FIELD OF THE INVENTION
The invention relates to the field of marine engine winterizing systems, and more particularly, to marine engine winterizing systems that can flush fresh water or sea water from the marine engine quickly and easily, stabilize the engine with liquid chemicals during the wintertime, and reclaim the liquid chemicals in the spring.
BACKGROUND OF THE INVENTION
Several attempts have been made in the prior art to provide a system that winterizes and dewinterizes an engine by pumping and storing engine coolant.
For example, U.S. Pat. No. 5,337,774 to Boyd discloses a system for winterizing a marine engine that includes a pump with a closed coolant storage tank working in association with a second pump and an open coolant recovery tank. The coolant fluid transfer lines connect the storage tank pump outlet to the recovery tank and connect the recovery tank pump outlet to the storage tank, further incorporating a control for operating the storage tank pump and recovery tank pump independently of each other. Antifreeze is discharged into, and removed from, the system by running the engine and pump at the same time. In winterization, antifreeze is pumped from the recovery tank into the engine and water is pushed out of the engine. In dewinterization, when water is pumped into the engine, antifreeze is pushed out and can be recollected in the recovery tank where it can be pumped to a supply tank for proper disposal or ruse.
U.S. Pat. No. 5,681,456 to Delport discloses a pressure-vacuum method for removing and replacing engine coolant in automobiles. The coolant is suctioned through a vacuum line into a holding tank and a pressure pump is used to deliver a new coolant. A quick connect coupler can be used for quick connection and disconnection to the engine.

Pressure line and vacuum line are made of metal, the tanks are made of glass, clear styrene acryl nitrile or polycarbonate plastic.
The marine engine 5 is refitted with special fittings 8 (to replace the current water draining fittings) and a plastic or nylon tube 45, is attached to the male disconnect fittings 9, which are mounted on a pressure-vacuum fitting bracket 50. The pressure-vacuum fitting bracket 50 is permanently mounted within easy access of the engine, whether on the engine itself or on the boat. There is at least one male disconnect fitting 9, for each water drain fitting on the engine 5, water exhaust manifolds 6 &7, and coolers (some engines have up to 7 fittings).
In operation, a person who wants to winterize or flush a marine engine, installs the fittings 8 onto engine 5, water exhaust manifold drain cocks, and all other drain cocks, and install lines 45, pressure-vacuum fitting bracket 50, and the male disconnect fittings 9. If there are five drain cocks, there should be five lines 45, and five male disconnect fittings 9, on the pressure-vacuum fitting bracket 50. This is a one time installation and only needs inspection periodically.
To remove liquids from the marine engine 5, the operator turns the handle on the control valve 20 to remove position, turns on the electric vacuum-pressure pump, then installs the female quick disconnect fitting 21, onto any male disconnect fitting 9. An indication that all the water has been drawn from that water chamber is indicated by the formation of air bubbles in the tank 15. While the electric vacuum-pressure pump is still running, the operator removes the female quick disconnect fitting 21, and installs it onto another male quick disconnect fitting 9, this process is continued until all the male quick disconnect fittings 9 have been emptied. The female quick disconnect fitting 21 has an internal shut-off valve that is pushed by the male disconnect fitting, which stops the fluid when the control valve is switched to fill position.
To install liquids into the marine engine 5, the operator turns the handle on the control valve 20 to install position, turns on the electric vacuum-pressure 1 S pump, then installs the female quick disconnect fitting 21 onto any male disconnect fitting 9. A graduated scale on tank 14 will indicate how much liquid has been installed into that engine connection. While the electric vacuum-pressure pump is still running, the operator removes the female quick connect fitting 21, and installs it onto another male quick disconnect fitting 9, this process is continued until all the male quick disconnect fittings 9 have been filled.
Referring to FIG 2, the marine engine winterizing system is comprised of a hand-operated vacuum-pressure pump 200, and pressure-vacuum fitting bracket system.
The marine engine 5 is refitted with special fittings 8 (to replace the current water-draining fittings) and adapted to a plastic or nylon tube 45, which will be attached to the male disconnect fittings 9 which are mounted on a pressure-vacuum fitting bracket 50. The pressure-vacuum fitting bracket 50, is mounted within easy access of the engine, whether on the engine itself or on the boat.

The pressure-vacuum fitting bracket 50, is mounted within easy access of the engine, whether on the engine itself or on the boat.
There is at least one male disconnect fitting 9 for each water drain fitting on the engine 5, water exhaust manifolds 6, 7, and water oil coolers.
In operation, a person who wants to winterize or flush a marine engine would install the fittings 8 onto the engine 5, water exhaust manifold drain cocks, and all other drain cocks, and install lines 45, pressure-vacuum fitting bracket 50, and the male disconnect fittings 9. If there are five drain cocks, there should be five lines 45 and five male disconnect fittings 9 on the pressure-vacuum fitting bracket 50. This is a one time installation and only needs inspection periodically.
To remove liquids from the marine engine 5, the operator turns the handle 205 on the hand pump 200 to align with an indicator 300. The operator then installs the female quick disconnect fitting 21I onto the male quick disconnect fitting 9 mounted on the pressure-vacuum fitting bracket 50. By moving the hand pump handle 205 in and out, the pump action will remove any liquid in the engine water jacket. The pressure line 210 can be put into any container to catch the liquid that is being removed. The operator then moves the female quick disconnect fitting 211 to the next male quick disconnect fitting 9 and repeats the process. When all male quick disconnect fittings have been emptied, all liquids from the engine water jackets will have been removed.
The operator will know when the water jacket is empty when he feels less pressure on the pump handle 205 when pumping air and not liquid.

The operator then installs the female quick disconnect fitting 211 onto the male quick disconnect fitting 9 mounted on the pressure-vacuum fitting bracket 50.
The pressure line 210 will now become a vacuum line and must be put into the container that contains the liquid that the operator wants installed into the engine water jacket. By moving the hand pump handle 205 in and out, the pump action will install any liquid in the engine water jacket. The operator then moves the female quick disconnect fitting Z11 to the next male quick disconnect fitting _g_ 9 and repeats the process. When all male quick disconnect fitting have been filled, the engine water jackets are protected. Counting the number of strokes it takes to empty each male disconnect fitting 9 will give an indication of how many strokes it will take to fill each male disconnect fitting 9.
