SX interior and gauges Gauges
Before replacing an instrument on your panel, check the following:

  1. Make sure all electrical connections are tight and free of corrosion.
  2. Check to see that the terminal has not pulled off wire, causing loss of continuity.
  3. Check to see that each instrument and sending unit is properly grounded.
  4. On the tachometer, check selector switch for proper setting for your engine. If arrow is in between the proper setting, erratic reading will occur. Proper setting for different engines are listed below.

    1. Outboards: One
    2. Four Cylinders Engine: Two
    3. Six Cylinder Engines: Three
    4. Eight Cylinder Engines: Four

    Note: Be sure arrow is at indicator mark and not screwdriver slot.

  5. Ground the sender wire to get full scale deflection on temperature, trim, fuel, and oil pressure.
  6. Moisture buildup on the inside of the gauge is quite common and harmless.
