impeller change during the winter

I wait and do my when I summarize it.

I change mine every spring. I have been told that even new impellers can break. Cheap insurance

Yes, if it's filled w/AF, it will partially drain out (experience). As everybody else has suggested, do it in spring.

it's to d*(n cold now... just go out and give it a nice big hug... and talk to it a little bit, then it will be happy for a month or so.. then go out with the vacuum and give it another hug... and so on.. soon it will be spring... well hopefully...

No, just saying it doesn’t matter. Old wives tale or more likely a real issue in decades gone by. Like I said, I thought it was a real concern for a few years then realized it’s not.

What's needed is a way to measure how much water the pump is pumping, this is ultimately all that matters. If it pumps out a 5 gallon bucket in 10 seconds with a brand new impeller, you can re-measure it each year and if it takes, say 20 seconds, change the impeller. You'd have to have a 'Y' set up on your water intake hose, though, and the only ones I've seen are those plastic things that I would not put on my boat. I don't want a plastic Y connector breaking in the middle of the lake and sinking my boat.
