Thanks for your comments.

Having read a lot of
Boating magazines while on the ... hmmm ... while sitting and contemplating the nature of mankind, I've generally seen that a small block V8 is most efficient at no wake speed and, more usefully, between 3000 and 3500 RPM. For me that works out to be 30 - 35 MPH (optimally) depending on load and trim due to "sea state". At those speeds enough of the boat is out of the water to minimize the drag. Dave's curve seems about right though I think he has a big block.
