[C320-list] Winterization

[Ken Geiger]

 I open the drain on Northern Dream #765's muffler and vacuum out the water. I then pump 8 litres of anti freeze through.  I normally then Vacuum out the antifreeze from the muffler but this fall I let the engine run on for a minute and the exhaust blew out most of the anti freeze I guess as there was none to be vacuumed out of the muffler.  

Northern Dream has for years been on Georgian Bay where the winter temperatures might reach around -20 deg C (-4 Deg F) or colder and I do not remove the compass but I do note that when we bought her a few years back the compass dome has some what appear to be fine cracks.  Is it cold Temperature related, I don't know.
Ps Gus can you tell me if you see this reply on the C 320 news feed.

Christian, my winterizing process sounds similar to yours in that I rely on the antifreeze to displace water in the muffler.  Also never heard of anyone removing the compass.  Gets pretty cool up on Georgian Bay also.
