Yes, there is a calibration switch (dial). On my boat it is on the front of the trim panel down by the drivers seat. About where your knee would be sitting in the seat. It’s a remote switch that goes up to the factory speedo. Some don’t have it and you have to adjust it at the back of the speedo under the dash. I’ll see if I can send a pic of mine.
