Interesting. In theory, the same size and shape prop should pump out the same flow as long as the AC motor is not at or near the full capacity. The prop spinning speed is determined by the AC current frequency, in our case 60Hz gives approx. 3600 RPM. In Europe at 50Hz the prop spins at 3000 RPM.

But at full capacity when the prop is pushing the limit of the AC motor, the slipping gets worse and it reduces the pumping efficiency. The stock 6045 pump motor should have plenty of juice for the trimmed prop, so the flow should be the same even if the magnets/motors are not very consistent.
