I am located on the north side of Lake Ontario. Have been winterizing boats
for about 20 years and I run propylene glycol through the engine (while running
on the hard) until it gushes out the exhaust. Works well for both gasoline and
diesel engines. Eliminates the risk of any remaining water
Hi David
Just thinking this through, there will be low areas in the raw water system
that may not be free of water so subject to freezing. Thinking the heat
exchanger and muffler. Running pump dry is an issue for most pumps. Passages
and hoses with no fluid will dry out perhaps causing is
Dave,
Brian did answer your question when he stated "Water left in low spots,
particularly the muffler."
Next time you have a chance to view the curvature of the hull and compare it to
the exhaust outlet, consider that there is a water lift muffler in between the
engine and the outlet. Yes th
Maybe check in your manuals, I still have the Waterlift muffler for my A4,
the manual said that there is no need to winterize the muffler since there's
around 1-2 inches of water in it. That waterlift is a rather large steel can (
14 in. ).SylvainC&C27 MkIII

David - to answer directly: relying on the raw water pump to move enough air to displace the remaining seawater is a bad idea. It’s not meant for that. Don’t do it. Howzat?Dave (ex 33-2 Windstar. )Sent from my iPhoneOn Nov 20, 2024, at 12:32 PM, Sylvain Laplante via CnC-List wrote:

Hi Dave,
Your method saves buying chemicals, and saves poluting the environment, but the
old method of sticking the engine's water intake hose into a bucket of
antifreeze and running the engine until the pink stuff exits the exhaust is
slightly more thorough and less crawling around. Our muffle
Doesn't mean it's good for the environment. Would you drink it?

This is getting off track and no one has actually answered my question. I know
there are many ways of winterizing the engine with antifreeze. My question was
what would be wrong with simply pumping all the water out of the system by
running the engine for a few minutes after the boat is hauled
After winterized my boat I got to thinking about the process of pumping
antifreeze through the engine and water tank system. Some people winterize
their house water system by blowing all the water out of the lines instead of
pumping in antifreeze. If you did the same with the seawater side of
Water left in low spots, particularly the muffler. A gallon or 2 of
antifreeze seems cheap insurance for an engine for me.

I can't answer your question, but I also thought about that recently and I
realized that antifreeze is running around the head. While the block is
cold, the thermostat is closed, directing the antifreeze around the head.
Never had a problem but was curious about the water that might be remaining

I never pumped antifreeze through the seawater side of my 2gm20f, and did not
have a problem in 10 yrs of Toronto winters.I did drain the seawater side
by disconnecting the lower water pump hose, and draining the seawater strainer
and muffler.

What's wrong with the pink stuff? I though it was supposed to be
biodegradable?

The thermostat controls the "fresh" water side with the permanent / toxic
coolant, not the raw water. Once the engine heats up [175 - 180* on a
Yanmar] it opens and the "fresh" water flows through the HX and is cooled by
the raw water from outside of the boat. At least, that is my understanding.
I also use barnacle buster and let that site for half a day. Gets all the salt
deposit and gunk out, then runs with fresh water for a bit before dumping in
the pink.

Dave -
I also recommend (versions of) this and your method.
I’ve put the raw water hose into my antifreeze and ran till it comes out
exhaust for the past 10 years. No issues in Buffalo NY or Maryland.

I winterize our air conditioner the same way as the engine, using pink stuff
for RVs. But I wonder if there is any chemical to pump through to clean the
inside of the hoses and tubing and air conditioner's heat exchanger?
Something to dissolve any scum or scale, improve efficiency, extend the
The best way to winterize is drain the raw water side. Flushing antifreeze
through is good also. I would also flush with saltaway, or something
similar first. Let that sit for a few hours to overnight
