While I think it would be best to drain, then refill, the vast majority of users will simply pump the antifreeze through the cooling system and "push" the water out the exhaust. That's one of the reasons to use a lower temp antifreeze: it allows you a little wiggle room if there is some residual water in the block and cooling passages. Running the engine a little longer will allow a higher concentration of the antifreeze.
Thanks for this video.. I'm about to winterize my inboard and this helped me to solidify the process (drain vs antifreeze). While some think this is too complicated, there are even more steps that can be taken to insure proper functioning in the spring. There is cable maintenance and lube as well as oiling down the engine to minimize rust. And one does not have to do this himself, a shop will gladly do it for $400-$600 depending on the amount of work you want done. I love having a boat!

Do you need to drain the block before you pump the antifreeze in or will all the water come out when you pump the antifreeze in?
