marina will pull the boat this week and set it up on blocks

i have a freshwater cooled engine, with a heat exchanger. my plan is
to pull the hose leading from the seacock and put it in a 5 gal bucket
of fresh water to flush the sal****er out.

then fill the bucket with 4 gallons of propylene glycol (the pink
antifreeze) and flush this through the engine, out the exhaust
manifolds and through the mufflers...

is this going to be enough? how fast is the engine going to empty the
bucket at 1000 rpm? any other secrets i should know about?

thanks much all

Bob, I'm not sure about winterizing something like that. My old Chris
Craft was a raw water system but it had an external Sherwood (?) water
pump and no heat exchange. I'm thinking that if you drained the heat
exchanger as planned then you might be able to give the boat a
transfusion ( or enema) as you've planned and be good. But I'm not
sure if the exchangers pump will pick the fluid up unless you have the
antifreeze jug higher than the hull.

It should work ok but I'd put the antifreeze container high instead of
on the ground.

Concerning the engine RPM, I'd say it would pull the fluid through the
exchanger rather quickly, and even if it shoots it right out, at least
you have the engine block flushed.

I may be wrong but that's the way I see it.

good luck, m'man!

thanks much, tim...as always

i think the water pump should flush the system...but i'll find out!

I've never owned an inboard or I/O, but do they have thermostats? If
so, it may be possible that without the thermostat opening, there
could be some passages that retain the raw water?

I thought I'd heard or read somewhere that some of those engines have
petcocks that drain the block, maybe just because of this?

Sounds like it's time for a professional opinion.

He has a fresh water cooled engine with heat exchangers. That means
that he already has (or should have) anti-freeze circulating through
the block and the thermostat. No worries there except to test the
anti-freeze and make sure you are protected for your climate.

On the raw water side, the technique you describe will work fine, and
4 to 5 gallons of the pink stuff will get the job done. It doesn't
take long to drain a 5 gallon bucket so this becomes a two man job
unless you have an on/off switch in the engine room.

Oh... I read fresh water cooled as raw water. And I missed the
significance of the heat exchangers. Thanks, now I know.

Like I said, I've had outboards in SC all the way. I don't need no
stinkin' winterization. :-

yeah that's what i needed to know...the wife will be at the kill
switch...and will run the engine at 800 rpm...just above stall

fortunately the thermostat is on the freshwater (antifreeze) side of
the engine so should be OK. i'll just be flushing the sal****er
side...heat exchanger and exhaust manifolds
