It depends on how the power boat is set up. Aerodynamics, weight and length all have a factor in how fast the boat can go. A power boat that is set up as a race boat will usually be up around 100 mph, but a regular power boat will usually go upwards of about 60 mph.
That is a boat driven by steam power.
