Winterizing a Seaward S600 water heater on a '97 Hunter 340
What is the best way to clear the water out of the heater?
TIA

Winterizing a Seaward S600 water heater

open the drain
turn off the power and then open the drain ... you might want to first connect a hose so you can direct where you want the water to go. I also open the water faucet to avoid an air lock.

All I do to my hot water heater is drain it.
I do bypass it in order to winterize the hot water lines in the boat.
BTW - My first year with a boat all I did was flush the water heater with anti-freeze, bust didn't drain it. In the spring that resulted in a blown out inspection post that needed a new gasket due to freeze expansion.

On my boat there are two water loops to the heater, potable water and the heating loop from the engine.
Putting the non-toxic anti-freeze in the empty water tanks and getting flow from both hot and cold water sides of all fixtures and sucking the anti-freeze into the engine raw water loop to protect that heat exchanger and the muffler will protect the equipment in the boat
If the boat is hauled out the through-hull drains should be closed so that you can move the valve a bit and close so some anti-freeze is in it to protect it. I do this with my boat in the water.
I also have three drains on the water heater to drain it, but this would not protect the water lines.

Water heater
The water heater on my 2000 H340 defies all logic. After I disconect the main domestic water lines I can open the drain valve and open the presure release valve but very little water comes out of the drain. I found that if I connect a short hose to the "Hot" water outlet and blow into it, I can get at least a gallon or more of water coming out of the "cold" water inlet. I then snake a small diameter plastic tube into the cold water inlet and suck out a fair amount of water using a hand-drill mounted pump. I then add about one gallon of the pink antifreeze stuff to the "empty" heater and it seems to stay in there all winter - with the drain valve full open. I have to flush it out in the spring when I recommission the water system.
