Re: overpropped vs underpropped
I think the analogy is flawed in the sense that as I drive my Jeep up a hill in 5th gear I can tell that I'm lugging the engine seeing the rpm reduced to below 1000 no matter how much throttle I give it. I then down shift to 3rd and the rpm goes up and more power is available. Now on a boat there are no gears to shift from considering that the tranny is set in my case at 2.1:1 and the pitch is pre set with no means of adjusting underway. Under calm conditions I can maintain 6 knots at 2500rpm but as the seas and headwinds increase my speed will be reduced but that rpm will remain at 2500 plus I can still wot it at 3000. I'm just not using the available hp if I had preset the pitch at a lower setting. My 2 cents.
