Is draining the block enough to keep it from cracking....?

[rundle@.not]

Is draining the block in an I/O enough to keep it from cracking, or could there
still be water pockets in it that could be enough to crack it? It seems they
should be designed so that can't happen, but are they? This particular one is a
140 hp straight four cylinder Mercury 1976-1979 model.

No, it is not.

When "winterizing", try hooking a shop Vac in reverse (if yours has
that option. My 29 dollar one does.) to the upper end of the rad hose
and blow air through the engines water passages while the petcocks are
open. It should get all the water out. Works for my V6 Buick. I have
those old " log " style manifolds.

Hook up may vary, but I hope you get the idea.

If you want to be really safe, warm up the engine and then run -100
antifreeze through the raw water system until it comes out the
exhaust. I've winterized a lot of engines that way and never had a
problem.

On my 140, U drain the petcocks, and pull the hose from the lower leg
to the manifold, and pour RV (pink stuff) anti-freeze down the hose
till it's running well out the lower end, and while leaving the
petcocks open on the manifold and the engine block, I pour the same
anti-freeze in the water pump hoses until it's running out all the
drain petcocks. I've had good success with doing that as well.

I've known of people who have taken the prop off the lower and put it
in a large vat (55 gal drum cut in half) , put the lower in it an run
the engine which gives the engine a total flush of water, but that
takes a lot of antifreeze and storing is a problem and it's a messy
set up.... but it works.

You can do it with a lot less antifreeze by using a set of "muffs" to
gravity feed right into the intake holes on the I/O leg. You just
need to rig up a jerry jug and some hoses.

I've tried that and didn't have the best of results. Then again, I
didn't really have a good set of muffs.

Not a good idea to use 100% antifreeze. Here's why:

There is a difference between -100 and 100%.

Ah, so it would be a brand name product that claims to protect down to minus
100 degrees F.

But, they are lying as:

propylene glycol is only able to protect down to minus 60 degrees F

The thing is, most RV antifreeze is only good to -50, so I'd kind of
like to know too!

The best I've seen is good to -60 degrees F at a 60% solution of
propylene glycol and water. How they get the claimed -100 degrees
F I don't know.

It's a marketing tool... They sell you a guarantee they assume you will
never be able to call them on. If you do manage to get your car into
-100, they will probably just pay it and go on saying they are
"guaranteed to -100) LOL!

Keep your trolling to rec.boats please...

Star-Brite makes a number of anti-freeze products. While you are correct
about the freezing point of propylene glycol/water mixes, Star Brite has
other
additives. The MSDS for the -100 deg formula is here.

http://www.starbrite.com/msdssheets/31700-msds-8-17-06.pdf

Note that the product contains 93% propylene glycol with no water so your
chart may not be applicable

They market a -200 deg product as well. I bet they work as advertised
though I've no experience with their products.

Shiteater can't claim he froze his balls off for two reasons. 1. He had no balls to begin with. 2. He lives in Florida:
