Camco Do It Yourself Boat Winterizing Kit, Gravity Flow Engine Flush System for Inboard and Outboard Motors, Includes Tank, Hose, Valves and Fittings

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

Pretty easy to operate, and materials seem to be of very good quality. I cannot say enough about how this has saved me big time money and time! As long as I have a boat, I will have one of these winterizing units.

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.

I wish all the fittings were solid brass. Updated to 4 stars. Used it today and it worked great! No leaks.

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.

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 product can save you lots of money

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

Does the job would recommend this product

Les valve de plastique me semble un peu fragile. Mais fait très bien la job. Simple et efficace pour remiser pour l’hiver mon Mercruiser 350 5.7 MPI. Faire fonctionner le moteur avec les oreilles sur le pied pour réchauffer le moteur ala température normale de fonctionnement afin que le thermostat soit bien ouvert. Ensuite on ferme l’eau et ouvre la valve du réservoir pour pomper l’antigel. Et c’est fait.

Un peu cher, mais très pratique. Tuyau et accessoires de qualité

Did the job.

I just did my Volvo Penta 5.7 with this kit and it worked perfectly. I just heated up the engine with the boat on the trailer for 30 minutes to ensure thermostat was open and then i switched the valves on this kit from water to RV coolant through the muffs. I ran 5 gallons of coolant into the system to be sure it got through the manifold and block. I then validated that it worked by pulling all of the drain plugs in the engine and it was pure coolant. Worked perfect. No more 500 bucks per year at the dealer!!!
