The drain plugs on seacocks are there for good reason. This was about a $600.00 mistake on a 1.5" bronze seacock......

Ouch! Two things, I always use a shop vac and blow out my sea cock and close it while the vac is running. Then I reverse the vac and suck out the water and add some pink antifreeze. For those that leave their boat in the water the majority of insurers will NOT cover freezing damage. The only one I found that covers it is Boat U.S. for a $20.00 specific rider. Don't just take your agents word for it, get it in writing.
That is good but still may not get out all the water between the valve body and inside of the ball when closed. That is what the drain plug is for. This owner left the valve open from in the water to on the hard and had never cycled it to empty it or pulled the plug. The water trapped between the valve body and ball is what froze. None in the hose but there was water trapped in no-mans-land that did the damage.
