Pink stuff - as in plumbing ant-freeze? I think I have something on that
too. ;-)

Use automotive anti freeze which is better for aluminium and the
different metals than domestic plumbing stuff.

Which is also toxic and illegal. Use the non-toxic kind. Walmart has
it in the RV section.

You didn't read the link did you? ;-)

The easiest way to do this is to fill a 5 gallon pail with non-toxic
anti-freeze, the pink stuff rated for 100 below zero. If the boat is
still in the water, warm up the engine first. With the engine shut
down, disconnect the water intake hose at the strainer.

Agreed, this way you're pulling anti-freeze in the same way as the water is
handled.

Just BE SURE to do it only when the engine has completely warmed up.
Otherwise the thermostat won't be open and parts of the system would still
have water in them.

My big issue with this method is that most systems are designed to feed
the manifolds regardless of thermostat position and unless your
thermostat is wide open when you use this method, most of the a/f will
be sucked in, then pushed out through the exhaust without ever seeing
the inside of the block. PLUS, it will be mixing with the water that is
already there thereby reducing the protection level (and possibly
passing the threshold of protection).

Adding 10% water to pure glycol, which freezes at 8 F, lowers the
freezing point to -90 F.

An interesting side point for sure, but there are few things in this
thread that are pointing us in a different direction. First, it was
recommended to use the 'pink' stuff which is usually plumbing
anti-freeze and should never be used in engines, secondly, no one ever
starts out with pure glycol because they're mixing it for their target
protection (plus a safety factor). Now throw in the variable that we're
going to blend our starting mixture with an unknown quantity of water in
the engine, that may or may not get totally purged and/or mixed and
we've got a situation I'd rather not be in personally.

Food for thought.

Since water freezes at 32 F, how could that possibly be true?

The easiest way to do this is to fill a 5 gallon pail with non-toxic
anti-freeze, the pink stuff rated for 100 below zero. If the boat is
still in the water, warm up the engine first. With the engine shut
down, disconnect the water intake hose at the strainer. If the
hose is long enough, put it in the bucket, otherwise make up a short
extension and place that in the bucket. Remove the air filter from
the carburetor. Start up the engine and watch the anti-freeze level
in the bucket. When there is about a gallon left, spray fogging oil
into the carburetor until the engine stalls. If it doesn't stall,
just shut it down. Replace the air filter and re-install the water
intake hose. Close the intake seacock and pour some antifreeze into
the strainer.

The engine is now winterized.

Nice post!

what to do about that?

Is the boat still in the water? If so then yes it will keep siphoning
from the lake.

Also, somewhere I got the idea that it's good to open the
system where the thermostat would go and fill it with
anti-freeze, to take care of pockets where water could
still be trapped and maybe even to keep gaskets etc
from drying out. Is that something I should do? If so,
would a 50/50 mix be good enough?

You should find what you need he
