Ah... downhill with the current... got it. 74 is a darn sight away
from 82.

It was a very large reservoir...no current. And there are many more
variables such as, weight, temperature, chop, wind, humidity, barometer,
etc.

It is not uncommon to have a "spread" of 10% on top end with a blown V8,
throughout the day because of these variables.

And it is interesting that less gas would give a higher
speed since the loss of weight in the rear would drive the nose down.

Apparently not.

Trim tab, "ride plate", Hydrogate, (you work for Tige or Correct Craft
or something? That is marketing speak!), whatever - a moveable plate
at the stern that alters the wetted surface.

Tom, the Malibu Corvette does not have a "moveable plate at the stern that
alters the wetted surface".

The ride "plate", is fixed, and does not extend pass the rear of the
transom. The purpose is most likely for strength.

Again, I see no reason (performance gain) for adding adjustable trim tabs to
a fixed prop inboard, other than to compensate for uneven (right to left)
loading.
