I have a PacFab Challenger 1hp High Flow pump that is making a loud whining noise. It is also leaking water underneath, where the pump motor is bolted to the impeller.

the motor indicates it is a 1.65SF Centurion Challenger

I believe this is the original motor on the pool, which was installed in 1994... could it be the bearings? is it best to fix or replace the motor or the entire hosing (motor and impeller section)?

Thanks.
