Impeller size

Moved from here.

(1) Yes you can but you would need to change the impeller to a 1 HP impeller: A.O. Smith 1.65 HP Variable Speed Pool Pump Motor Square Flange - ECM16SQU - INYOPools.com

Why a 1 hp impeller instead of a 1.5 hp impeller? I saw the Q&A on the INYO site regarding replacing a 3/4hp for a WhisperFlo but I was wondering if you had any insight?

This is a dated thread but at the time, the motor that I posted is a 1.65 THP rated motor and the largest Whisperflo impeller that you can use with that motor is a 1 HP (full rated) which has a 1.65 THP rating. Whispeflo impellers are full rated rather than up rated so much like a 1 HP full rated motor, the THP is actually 1.65.
