The Executive pumps allow you rotate the wetend to 3:00 - 9:00 or 12:00 position. We ship them at 12:00 unless otherwise told.
We suggest that you compare amperage (amp) ratings versus horsepower (hp) when sizing your current pump as many spa manufacturers use a "marketing horsepower" that is often different then the motor truly runs at.
