I have a 2005, 216 with a Faria speedometer. My tachometer and hour meter stopped working, and then my speedometer did not work correctly. The Marina mechanic said the gauge was bad and the tachometer was a computer issue. Purchased a new gauge, but that did not fix it. Then was told the wheel was broken, replaced that and the speedometer still bounces around. Could this issue be tied back into the computer as well?
