No prop is loaded and unloaded like a hydro prop, and its only worse the more power you put to it.
With the twin props, they are arranged 90* out of sync, and the forward thrust is relatively even, although still off and on per side during the run. The fact they are counter rotating helps immensely with the stability of the boat, and counters the "side walking"

You can see the on/off in the rooster tails. This is actually a mild case.

I had to wait til morning when I was a little more clear headed and I still don't get what you are saying. Please talk hydro or flatty . I get the hydro makes no thrust when the prop is in the air. Are you saying a prop doesn't generate thrust for every degree of rotation that it is in the water?
