The invention is a paddlewheel aerator having a support structure, a drive mechanism contained within the support structure, a rotatable shaft extending horizontally from the drive mechanism; and a plurality of paddlewheels surrounding the shaft. A plurality of support legs are formed integrally with the support structure. In a preferred embodiment, a watertight drive box is positioned within the support structure. The drive box has a removable cover and a substantially water tight seal for preventing ingress of water. The drive box contains a motor drivably connected to the shaft. The motor is contained within an upper portion of the drive box so that the motor is positioned at a vertically elevated level compared to the shaft.
