Ao smith b985 or century B2984

[Oldmxer]

My ultra flow pump has a B985 AO Smith motor. Local pool supply only has Century B2984 motor they claim will work.
The 2984 is a 2 HP 2 speed, but amps look to be different.
Question is, will it work or should I wait for the B985 motor

The B2984 has a slightly higher THP so it would work fine replacing the B985. But the B2983 would also work and be a little closer to the existing motor.

OK, I assume THP is total horse power.. the 2983 shows to be a 1.5 HP though. which I assume I need the larger motor to match the impeller.
let me know if there is something I need to read....

Last, Is the 2984 just more efficient on the lower speed? it only shows 1.8 amps
and my existing B985 shows 3.5 amps. (which it runs on most of the time any way)

Thanks again.

The 2983 has a label HP of 1.5 with a service factor of 1.47 so the THP is 2.21. Your old motor has a label HP of 2 and a service factor of 1.1 so the THP is 2.2. The 2983 is a tiny bit larger than your old motor so it should work fine.

The B29xx series are more efficient than the older series especially on low speed.
