Update. I put this motor on using the xxx10 impeller. 1.65 hp at full rpm. After over 24 hours it's running below FLC. Perhaps the motor was defective. Thanks to all who pitched in.
Motor overheating

That is still about 2,200 watts, which is high for that pump.
Variable speed motors will usually have some sort of overload protection to keep the amperage below a danger point.
Maybe the motor is limiting the speed to keep the current below the danger point.
To me, it seems like there is something causing excessive amperage, but I do not know what it is.
That is not how it works.
The power draw is based on the pump, not the motor.
That pump should draw about 7 to 8 amps maximum based on the pump.
If you put a bigger motor on the pump, the current should still be 7 to 8 amps at 240 volts.
The full load amps of the motor could be 12, 14, 16, 18, 20 etc. and it wouldn’t change how much load the pump puts on the motor.
The load remains the same.
I thought you were talking about the motor. I'll not disagree on what the complete pump/motor should draw. I'm happy with the motor not being pushed above its design load.
