Thank you for contacting Inyo. The dual speed motor option for your Whisperflo pump is model B2983. The variable speed option is model ECM27SQU. We would also recommend replacing the seals when you replace the motor. The tune-up kit is GOKIT32. Use GOKIT32SALT if you have a salt water pool.
For more information on the California requirements, check out our article titled “California’s New Variable Speed Pool Pump Law”.
Would it be possible to also install the 1.65THP variable speed motor for the WFE-6 pump or does it have to be the 2.7THP? If so does the impeller need to be changed?
If you don’t change the impeller on the WFE-6, you’d have to go with the 2.7HP variable speed motor. If you want to use the 1.65 variable speed motor, you would need the 5074-27B impeller.
