How do I know if this board fits my hot tub?
The Balboa Mach 7/RS81 is designed for specific spa models, particularly those from Aquarest and Dream Maker that utilize the Mach 7 control system. We recommend checking the part number on your current circuit board or consulting your owner's manual to confirm compatibility before ordering.
