hello all. this is my first year with this boat and it is coming time to winterize it. Was reading boat trailer magazine and saw a do it yourself winterizing kit from starbrite and thought it looked pretty interesting. Was wondering if anyone has used this?. It has a 5 gallon tank with a petcock on it. You fill the tank with antifreeze, put your muffs on the engine hoke up a hose to the muffs and the tank. Start the engine and let it idol till you see antifreeze come out the exhaust/water outlet. Shut it down and you are all set. Sounds to easy to me, but if htis works it beats climbing in the engine to pull plugs and unhook hoses. Any thought are greatly appreciated. Thanks
