[C320-list] Winterizing the Yanmar 3GM30F

[Daryl Hunt]

My usual process for winterizing the engine is to run -50F antifreeze 
through the raw water inlet until it comes out the exhaust.  My concern 
is that this doesn't give the engine time to warm up enough to open the 
thermostat, potentially leaving water in the engine block.  I haven't 
seen any comments or procedures to deal with this so perhaps my concern 
is unfounded?
