Tend to agree, 40 knots = 46mph. Had 47mph SOG indicated out of my SR5.4 running a 21" P stainless prop at something like 5,500RPM.
Couple of points though:
1. Can't maintain anything much over 44/5mph as it becomes ehm "exciting" and I either have to throttle back or steer slightly to one side.
2. How the hell do you take a clear photo of the instruments at 40 knots plus?!
I can't even read my tacho accurately at that speed, although I haven't had a flat calm day yet.
