The amp draw listed on a motor label is simply the maximum rating. It doesn't tell you what the actual amp draw will be for the motor. That depends on the impeller and the plumbing and motor efficiency.

Also, the 2 HP is not really twice the HP. The first motor has a THP (total HP) of 1.65 (1*1.65) and the second motor 2.2 THP (2*1.1). So that is a difference in THP of only 0.55. But that doesn't doesn't buy you anything since the two motors will draw about the same power so save your money and go with the cheaper motor.
