Yes, you can order a new drive unit as well, part 6200.70. I would check the cords for cracks. Cords can be made of only two materials for use in water, EPDM, which is used in ponds because it resists UV but is destroyed by Ozone, and PVC which has the opposite characteristics. Over time the PVC hardens from exposure to UV from lighting. It can become brittle and crack, it can also just get stiff and be fine for many years. I would just keep an eye on it, check it whenever you remove the wavebox for cracks or tears.
