Abstract

A system for winterizing boat engines includes a "Y" valve having stop cocks located on the common duct and each arm. One arm is connected to a source of flushing liquid, and the other to a source of anti-freeze. The common duct is connected to the engine.

Claims

1. A device for winterizing boat engines with an intake port, comprising:

(a) a source of flushing liquid;

(b) a means for regulating the flow of the flushing liquid at said source;

(c) a container for holding antifreeze at a higher elevation than the engine to be winterized;

(d) a first stop cock fixed to the base of said container for regulating flow of antifreeze out of the container;

(e) a "Y" valve having two arms and a common duct;

(f) a hose connecting said first stop cock to one arm of "Y" valve;

(g) a hose connecting the source of flushing liquid to the other arm of the "Y" valve;

(h) additional stop cocks on each arm of the "Y" valve to regulate the flow through each arm independently;

(i) a hose means adapted to connect the common duct of the "Y" valve to the intake port of the engine to be winterized.

2. The device described in claim 1 wherein the hose connecting the first stop cock to the "Y" valve to permit the flow of antifreeze and the hose connecting the common duct of the "Y" valve to the intake port of the engine are made of clear plastic.

3. The device described in claim 1 wherein the container for antifreeze is a bucket with a capacity between three and seven gallons.

4. The device described in claim 1 wherein the flushing liquid is water.

5. The device described in claim 1 wherein the flushing liquid is a chemical cleaner.

6. The device described in claim 1 wherein the flushing liquid is stored in a tank means adapted to be located at a higher elevation than the boat engine.

7. The device described in claim 1 wherein the source of flushing liquid is a water faucet.

8. The device describe in claim 1 where the hose means adapted to connect the common duct of the "Y" valve to the intake port is attached to the intake port by means of flush muffs, which are a type of removable clamp.

9. The device described in claim 1 for use in inboard engines with a through-hull water intake, additionally comprising a "T" valve on the through hull water intake, and the common duct of the "Y" valve being adapted to be connected to the "T" valve.

10. The process of winterizing a boat engine utilizing the device described in claim 1 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

11. The process of winterizing a boat engine utilizing the device described in claim 2 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

12. The process of winterizing a boat engine utilizing the device described in claim 3 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

13. The process of winterizing a boat engine utilizing the device described in claim 4 by first flushing the boat engine with water and then filling the boat engine with a pre-measured amount of antifreeze.

14. The process of winterizing a boat engine utilizing the device described in claim 5 by first flushing the boat engine with a chemical cleaner and then filling the boat engine with a pre-measured amount of antifreeze.

15. The process of winterizing a boat engine utilizing the device described in claim 6 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

16. The process of winterizing a boat engine utilizing the device described in claim 7 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

17. The process of winterizing a boat engine utilizing the device described in claim 8 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.

18. The process of winterizing a boat engine utilizing the device described in claim 9 by first flushing the boat engine with the flushing liquid and then filling the boat engine with a pre-measured amount of antifreeze.
