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?
