Response to Hi David, Yes this motor is the correct replacement motor for the Magnetek / Century Centurion 10-177450-03 This motor does not come with the impeller however the impeller normally does not need to be replaced unless the impeller is broken. We suggest replacing your shaft seal. To suggest the proper shaft seal or impeller we would need to know the make and model of your pump common models are the Pentair Whisperflo, Pentair SuperFlo, Jandy Stealth, etc.. Could you reply back with the model of your pump or you can send us some photos. To send photos simply click on the reply link below and upload your photos.
