Those props have a governor that keeps the speed constant, regardless,
within limits, of load or throttle setting. More usual to go through
the range of pitches by varying the RPM with the prop governor. That's
the way everyone I ever knew did it. An airboat doesn't need a
variable pitch prop, as it doesn't climb and dive.
