Wintering Help

I will be winterizing the boat this weekend and was wondering if anyone had a handy check list that they have made for themselves? She’s an 87 340 Sundancer 454’s freshwater cooled with AC/heat. I’ve been told many different things regarding the Carb’s. 3 and 1 oil into the carb at the end to choke out motor, no 3 and 1....marvel oil and on and on. Any wisdom from the group?

Here's mine:

Good list.
I blow the water out of my potable water system, disconnect the potable water system and run it to make sure all water is out of it. I used to do the Pink treatment but it took several flushes to get rid of the taste.
