New guy here

I have a 2007 Robalo with a 225 Honda . In the past I have had the dealer winterize her, but this year due to economy will do my self. Any one help with a complete list of what needs to be done on a late model 4 stroke ? Old days just pulled plugs, gave a shot of marvel mystry oil, fogged with same through carbs. greased prop and sprayed her down with crc....
Thanks in advance
Jimmy
