How to Winterize a 4.3 Mercruiser?

[maczilla23]

I have an 04 4.3L Mercruiser engine that I need to get winterized. I was wondering if there is a place showing step by step instructions on how to do this or if someone could help me out. On my 88 back in the day i used to just pull all the plugs and hoses. I was wondering if there is an easier way? Like filling the block with anti freeze. thanks in advance
