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).

Are you leaving it in the water for the winter? Then there's other
things you need to do...

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!

Yes, I'm leaving it in the water. I'm in GA though, so there's no
need to worry about the lake freezing. I do need to worry about
the motor filling up with lake water, or even filling to a certain
point though. It seems that if I fill it with anti-freeze, or even
50/50 then it would eventually become a pretty even mix of
water and anti-freeze throughout the whole system which would
be full and allow no more lake water to come in, prevent any
pockets of just water which could freeze, and keep gaskets
etc from drying out.

Where do you get the Propylene Glycol? That's what is
used in fog machines.

Also has been used as a a food additive.

It's normally what's labeled "non toxic" anti-freeze.

What you may need to worry about is your sea cocks freezing and
splitting though. You need to isolate the engine from the sea cocks and
then winterize the engine, then you need to fill the sea cocks with oil
to save them (and your boat).
