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!
