Raptor 400 clarification in simplest form…

1 - winterization = draining engine from all relevant points (5 if my memory serves me right)

2 - if one chooses not to drain, is running the engine to temp to allow for thermostat to open and then filling with antifreeze equally as beneficial as #1?

3 - for those of you who drain. Do you THEN fill up with antifreeze to avoid corrosion?

4 - Opinion, what’s best? #1, #2, or #3?

I recognize these examples do not include oil and filter change, fogging (if one likes to do it), filling tank and adding STABIL, draining ballast and winterizing ballast pumps (running backwards and forwards and/or running antifreeze in reverse), and all the other necessities (fluid exchange/top off, bleach in bags, etc).

I’m comfortable with winterizing. Just wanted to seek advice on BEST practice.
