what is wrong w/ heating the boat up to operating temp. and running
antifreeze through the earmuffs w/a sump pump? of course u have to have all
the plugs and drains closed.

I have not heard of pouring antifreeze into the engine with the plugs
out.


I think he is just trying to see if he has cleared the passages.

I just drain at all the plugs and I'm done.

The last time I did that on a boat, the next spring, the casting plug was
laying in the Bilgh. It gets cold here in NJ. Antifreeze is cheap.
