Speedometer is off

[Horwitz]

Hi gang,
by 2014 Mondo's speedometer sender (paddlewheel) failed- read zero, and was replaced. Now compared to GPS, when the speedo says 30mph, it is about 32.5 by GPS. I have tried turning the knob under the left side of the dash to both extremes but it does not seem to change the speedometer setting. has anybody calibrated their speedometers? what am I doing wrong? I tried with it on cruise, and with it off cruise.

I don’t recall the menu buttons specifically, but you will need adjust the paddlewheel offset on the dash screen.

That is what I did- I put a 2 mph offset in. That is fine for skiing speed. However, then the speed is totally wrong when in the no wake area (which i suppose does not matter really)...
