Logic would suggest that "muff " water will get to the same places as lake or sea water . The flush port will also get everywhere that sea water can get as well .

I’m a big believer in using muffs. Absolutely no question water goes everywhere. Does flushing water actually get down to the impeller using the flushing port? Not so sure.

Flushing port def gets to the impeller....thats not my concern since Im doing the impeller every other season anyway.does it get to the entire upper???? thats my concern???? I think not unless motor is warmed up and stats open.Charlie

Yeah but some t/stats have a small bypass figured in there somehow and the t/stat is pretty much the last thing the water gets to . The t/stat doesnt make a perfect seal and will leak enough to purge any air out as the water gets pushed up thru the exhaust cover and the block and head (s) .
I would rather use muffs (yeah #uck the neibours , they get enough free fish ) and get a bit of warm water flowing at a decent rate .
