They are used to calibtrate your speedometers. Use a hand held GPS and take your boat for a spin. Use the knobs to match the speedometers to the GPS as you are driving. You will see the speedometer needles move when you rotate the knobs.

Supposedly for calibrating when you're running the slalom course. I toyed with setting mine and then super glueing it in place since it always seemed off every time we'd launch. But when PP replaced a speedo I figured I'd just leave it alone.
So when is this "old enough to know better" supposed to kick in?

If it's an Airguide these guys can convert it to a GPS Speedo for $226 + shipping.

You could just replace the gauge entirely I guess?
