You posted; "Reduction gearing has EVERYTHING to do with it."

It seems you've elected to ignore, Prop Pitch, Prop Size, and the Medium
it is operating in. You have also neglected to recognize throttle
control

It was just as valid as your response that reduction gearing has
NOTHING to do with it.

Try moving a 40,000 lb displacement boat with a 225HP 2 stroke outboard
running at 8000 rpm. Then try the same thing using a 225HP diesel
running at 1800 rpm thru a 3:1 reduction box.

You oversimplified and are now trying to dig yourself out.
