Sort of funny comments, but don't need to get 100% out, just enough so what ever is left can expand it large voids so no pressure is exerted with enough force to damage anything
As for bear metal, inside a block, head other water channels and comparing to combustion sealing surfaces. The water jacket areas have no surfaces which are used by other moving metal parts for contact sealing surfaces.

just a fyi,a few years ago i filled a glass jar with the -50 antifreeze from menards and left it outside in a place where i could easily observe it.it got slushy but it never froze solid.i will also add that a open system is going to see corrosion due to the impurities in the water and nothing will prevent this from happening nor will any antifreeze reverse this.living in the midwest it is not uncommon to see the temp go down to -15 in the winter time.take from this information what you want as i am not telling anyone how to winterize,i am just providing information.

Normal everyday saltwater use and normal everyday fresh water use will probably contribute to any type of corrosion way more than the cheap pink antifreeze that has “corrosion inhibitors” ever will.
Changing your impellors every 1-2 yrs should be the norm anyways.
Do what makes you comfortable and what has worked for you. Obviously all methods work as long as done correctly.

If I was to leave antifreeze in my raw water side all winter I would definitely step up to the -100 good stuff. I use the cheap pink crap to make sure after purging all the water out that I remove any little bit of water that remained in the system. I then drain the pink out. Never an issue.

I always abide by staying away from the ethyl alcohol based products and use only those that are propylene glycol based. Yes, it typically costs a little more. The alcohol versions will dry out rubber hoses and components.

What Merc has is ZERO ethanol and NO Alcohol. Very few has NONE. ALL have water in the mix. some as much as 75 percent water. You do not want that.
What Merc has is water, corrosion additive and pure poly propylene not recycled and no glycerin -- many have glycerin.
