Chick,
Probably you know that already, but be very careful when you attach a hose to the tee with any pressure (domestic water pressure) in it. The raw water pump does not provide a positive lock, so you can flood the engine and create a hydrolock. If the engine is not working and the water is flowing, it will collect in the muffler and then back up into the cylinders. And don’t ask how I know. Generally, the water pump needs to _suck_ water. Hence the idea of a bucket in the cockpit or on the cabin sole.

This allows you to easily check or clear a blockage while cruising and easily winterize the engine, in or out of the water. I keep a bronze plug screwed into top port except for winterizing. I have a short maybe 4' length of 3/4" hose w a ball valve. I place the hose in a 5 gallon bucket of antifreeze and suck the pink stuff through the water strainer, the pump, the heat exchanger, muffler and exhaust hose. The thermostat only throttles the fresh water, not the raw water, but I usually warm the engine to change the oil, do that first, and then winterize. I like this setup because it allows me to connect a water hose in the spring to test run the engine prior to launch. I like to be sure she'll start before I have her picked up by the travel lift. I rig a second bucket under the exhaust and catch the antifreeze and use that to treat the sinks, ice box, bilge and bilge pumps.

For 20+ years all I’ve done, is close the engine raw water in, run the engine while pouring a couple of gallons of antifreeze in through the top of the raw water strainer. When it comes out pink at the exhaust end I stop. Once on the hard I open the raw water intake and let whatever remains in the intake hose drain. Is this a purely an in-water issue?

Pretty simple. Rob Abbott AZURA C&C 32 -84 Halifax. N.S. On 2015-09-28 2:56 PM, David Knecht via CnC-List wrote: My solution is simpler. I found a tubing size at the hardware store that fit snugly into the outside opening of the raw water intake. I got about 15’ piece, fill it with antifreeze and plug one end into the intake and the other into a bucket of antifreeze on deck. I then start the engine and wait for the antifreeze to be sucked through and come out the exit port on the transom. It takes surprisingly long, before the suction starts. I am presuming that means the thermostat controls the raw water flow through the heat exchanger, not the closed loop antifreeze flow?

Has anyone done this? Any disadvantages? What type of valve did you use? All the best, Edd Edd M.
