Aqua-Flo by Gecko XP2e 2.5HP 1 Speed
This pump can be found in many different Hot Tubs in various forms. It has 2 inch outlets and will work in place of Waterway,GE, Emerson, A.O Smith and in most cases the unions will wind straight on.
You may find that your pump has a smooth body as opposed to this style of the pump but as long as the ratings are the same it will still work. In most cases, you will find that the wet end is the same but the motor may be made by a different company.
