Speedomete

[jsokol]

I have a 2004 21I, the speedometer is not reading accurately. I’m talking 10 to 15 MPH. The accuracy starts to diminish at speeds above 10 MPH. Are there any adjustments?

For the sake of my skiers arms, I need help…

Have you tried using a hand held GPS? My understanding is that its your best way to calibrate your speedo.

Yes, that’s how I determined the inaccuracy. Is there any adjustments to calibrate the speedometer?

I havent not done it myself so maybe someone can chime in here. On my boat their is a dial surrounded by dots that allows you to adjust the speedo. Sorry I couldnt be much help. :(

Try this. Look on pages 2-4 of the manual not the pdf document.
