ericroline is on a distinguished road
Cal 9.2 with 2GM20, 14Dx12P RH prop. Rpm will go to 3600 while underway , but will not go much over 2400 while at the dock in forward. The engine RPM and hull speed are at about 60% efficient, 40% prop slip, up to 3100 RPM which is max hull speed. More RPM does not equate to more hull speed.
