I have a Coleman Model 455 hot tub with ozone generator that was installed in 2003. I need seals for the motor/pump which is a Flo-Master XP2, Model #06125474-2. Motor is an Emerson 2-1/2 hp. The impeller has #9169425 embossed on the outer edge and the shaft has two white dots. Do you have seals for this unit?
