Re: Jacuzzi Magnum Force
the motor you need is an AO Smith Centurion B836 (2 HP, SF 1.2 Brake HP 2.4) or AO Smith ST11202 (full rated 2 HP, SF 1.3 Brake HP 2.6) based on currently having a Centurion (AO SMITH) 184950 motor on the pump. The B836 is what you currently have. The ST1202 is a universal replacement motor. Both are made by AO Smith.
When you replace the motor you also want to replace the seals and O-rings.
You also might want to consider replacing the motor with a more energy efficient two speed motor of the same high speed HP and same mounting (threaded shaft, C mount), also available from AO Smith in both the Centurian (B809 or B2984 which is energy eficient on both low and high speed) and AO Smith lines (STS1202R). If you go with a 2 speed motor you will also need to get the swith to select low or high speed (mounts on the pump motor) unless you have some type of automatin system that can select pump speed.
