I would think so too. The report I got on high drag from a
freewheeling prop was a story about a redrive that used a sprag clutch
as the anti-torsional resonance device. It also lets the prop
freewheel when the engine stops. The story said that there was very high
drag in this mode.
It does not add up so I think there were other factors at work.

I wonder if a free-spinning prop on a broken tranny would not
have the same
drag as a spinning prop which is turning the
motor? I'd be inclined to say
they would differ.
