Dunno much about inboards but the outboard guys say you really should
swap props if you are running on one engine to prevent "lugging". If
it was properly propped to run 2 in the power band, one is going to be
straining at much more than hull speed.

Most twins have counter-rotating props. Swapping them would make you
run in reverse.

I think you misunderstood his comment. He did not mean swapping them
port to starboard and vice versa. He meant swapping them for new
props with a lower pitch, sort of like shifting to a lower gear.

You are probably right. I'm not afraid to admit when I'm wrong!
