Way, Jose..

I look at it this way. There is 50 more available horsepower at 6000
RPM. Thus, it makes total sense to me that given the same factors -
meaning inertia and momentum - that 50 additional horsepower driving
the props will give better speed.

I think you take perverse pleasure in being wrong. ;-)

The given scenario was at steady state equilibrium, no
acceleration. Both motors are producing essentially the same
power unless there is a slight weight/drag difference. The
200 would be at a higher percentage of max throttle than the
250 however.
