John:
Thank you ....both good tips...your first one could be the culprit but
your second one could also be the culprit.....the antifreeze (Preston)
is approx. 8 years old....I will flush and replace it before Fall layup
and see what happens. As I said earlier, it does not happen after
launch and before haul....just during the cold of winter.
A few years back, one of the engine block antifreeze drain valves came
loose during the sailing & motoring season which was noticed when
antifreeze entered the bilge....a little stress until the loose valve
was detected. Some times we get lucky!

Check to insure your engine block drain valves are tight before winter
storage. Second thought is weird but offered anyhow. Is antifreeze fresh?
Could there be a blockage somewhere where the antifreeze is diluted and
freezes which would expand and force the top stuff out somehow. I said it
was a weird thought! I will discuss it with the mechanic at the yard who is
pretty sharp and seen most things.

Subject: Stus-List Antifreeze Mystery
After the engine is winterized in the Fall, I place a plastic pan under
it.....not sure why but I do. Every Spring, there is approximately a half a
cup or 250 ml of antifreeze in the pan.
I have looked everywhere for the source of this antifreeze but I can't find
out where it is coming from. The boat was launched 3 weeks ago, the engine
has about 3 hours on it since then, the pan is still under the engine but
there is no antifreeze in it. And the antifreeze does not appear during the
sailing season.
I notice every Spring the level of the antifreeze in the 'overflow
container' is down a bit and I refill to the 'FULL LEVEL' but that container
is not leaking. It's a mystery!
Anybody experience this and/or have any ideas where this antifreeze could be
originating from?
