[C320-list] easy way to winterize the raw water and conform toABYC code?

[Chris Descher]

I set the jugs on the cover over the water tank and run the hose from the
jug to the T valve.  I start the engine, so raw water is going from the lake
through the engine.  Then I switch the T valve from raw water to the jug,
and it doesn't lose prime.  If I switch quickly to the second jug it still
doesn't lose prime.  After I start the second jug, I go back to the cockpit,
look over the back, see pink stuff coming out and shut off the engine.  For
me, it's an easy one man job.  When I bought the boat, this was already
installed.  Now I'm a little concerned about what Jeff mentioned on the
brass fitting.  I try to remember to close my raw water through hull when I
leave the boat, so maybe I shouldn't worry too much.

Chris,

Does the water pump pick up prime from the jugs in the cabin or do you have
to elevate the jugs (to the cockpit say) and fill the hose to get the
antifreeze started through the pump?

I think that I've got something like what you're describing.  It's a brass T

valve installed between the through hull and the engine.  In one position,

it lets raw water pass through.  In the other position I can feed

antifreeze.  When I want to winterize,  I take a couple of gallon jugs of

antifreeze to the aft cabin.  Then I put one end of a 6' section of vinyl

tube on the empty hose barb of the T valve and the other end of the hose

goes in the antifreeze jug.  I start the engine, turn the T valve to the

antifreeze position, and by the time I've run two gallons of antifreeze

through, it's done.  I can assemble, winterize, and disassemble in well

under five minutes.  This allows me to easily use the boat throughout the

winter with minimal hassle.  I don't know about ABYC code, but it works.

I recently was looking through the Forespar catalog

(http://www.forespar.com/pdf/M20-marelon-plumbing-product-chart.pdf) for

head vent parts, and while doing so a thought occurred to me.  I have been

seeking a permanent way to provide easy addition of antifreeze to flush the

raw water side of the engine.  I looked at adding a Prestone radiator flush

kit into the water supply hose after the raw water intake seacock, but I was

concerned about (i) inability to properly double clamp the hose as per ABYC

standards for below water line fittings, (ii) whether it was wise to trust a

screw on type cap to seal the flush kit (leaks or failure would be very bad

!!), (iii) would I pass a marine survey when I sell the boat in the future

or (iv) would I jepordize my insurance coverage in the event the

'non-marine' part failed and flooded the boat.  A standard Forespar 'Y

valve' (such as part number 902001 MF 853 found at

http://www.forespar.com/pdf/M20-marelon-plumbing-product-chart.pdf) would

provide a two source supply to the raw water system and meet all ABYC

requirements.  One leg provides fresh water from the thru-hull and the other

leg of the Y valve allows the antifreeze supply line to be directly plumbed

into the raw water system.  Which supply stream (either raw water or

anti-freeze) proceeds through the strainer and into the engine block is

controlled by appropriate positioning of the Y valve handle.  Thoughts?
