Camco Do It Yourself Boat Winterizing Kit (65501)

Simple. Saves money! This 3 gallons of RV antifreeze and a little fuel stabilizer in the gas tank and you're good to go for the winter

Used it to winterize my Rc. Worked great .

Tub works great, hold plenty of fluid, and is simple to use. I have a 5.7l mercury and it worked well for winterizing. Hose was good, connections weren't thin and cheap. No issues.

if you own a boat, this is a must have item, no more trying to get at hard to reach block drains , takes all of about 5 mins to hook up the ears, fire up watch for pink coming out, DONE

This a great kit to winterize your boats inboard engine. When using this kit it is critical that you run the motor up to operating temperature before you start allowing it to draw in the anti-freeze. You need the engine to be hot so that the thermostat opens and pumps anti-freeze through the entire engine. I started the boats engine using the setting for allowing only water to be drawn into the motor and let it run up to operating temperature and waited for several minutes before shutting the engine off so that I could close the water feed and open the anti-freeze valve, restarted the engine and let it draw the anti-freeze into the engine, this took several minutes. Once the anti-freeze was gone, shut the motor down and opened the freeze plugs on the exhaust manifolds and engine block, pink anti freeze came out of each point confirming that antifreeze had gone through the entire cooling system. I then removed each spark plug and fogged each cylinder with cylinder fogging oil. I had added Sea foam to the fuel last time I filled the tank on the boat so my fuel should be good for the winter. I use to remove the top hoses and open the freeze plugs on the engine, pour anti freeze into the hoses until it came out of the freeze plugs. Using this kit definitely made it easier, you just have to be certain that you did fill the entire cooling system with anti freeze.

Exactly as described and worked perfectly. Obviously I won’t be 100% sure until the spring, but I’m 99% sure I’m completely ready for a hard Michigan winter. Saved myself $400 doing it myself.

This system works perfectly!! I can't believe I've been paying someone to do this for me for over 20 years! Highly recommend!

Awesome product. Have used it for years to winterize my boat. Simply shut the antifreeze and run the engine till it’s warm. Shut the water, open the antifreeze and I just run it till it’s empty. 5 years without issues with negative temps. 10/10
