Ok, here's a third alternative for winterizing. Most marinas in the Ches_Bay have a "push boat" to manuever boats into the travel-lift. So, I usually do it with Mondial in the water. Of course, I first close the seacock, but then rather than taking the hose off from the seacock, I disconnect the water intake line from the pump inlet. I then use a short length of hose to put it directly down into the jug. What's nice about that is that it's right in front with the engine cover removed. I use pink stuff full strength (-50 degrees) and run the engine until I see pink coming out of the exhaust. My assumption is that the small amount of water between the pump and and the seacock will get antifreeze through osmosis.
