I was led to believe the reason for removing the impeller was to not have it in 
a single position for a number of months – it could take a set and not work 
correctly. I did that religiously for a few years and then stopped bothering 
after seeing no ‘set’. I change it every couple of years anyway (have quite a 
collection), and have had no problems on start up. I do keep a small heat 
source on board during the coldest months (middle Maryland, so it is not too 
bad) so probably don’t get the horrid minus temperatures.

There is a school of thought that maintains that the impeller might deteriorate 
in the antifreeze, especially, since most of the AF is Ethylene Glycol. IIRC, 
the better one would be Propylene Glycol, but it is not easily available.


Btw. if AF drains, it is only better (you don’t have to worry about water 
diluting the AF.

I am curious about why you advocate taking the impeller out.  Won't antifreeze 
drain out of your engine when you take the cover off the water pump?
