Grady-White installs full instrumentation on pre-rig boats. The instruments are electrically
connected to the ignition key, and will operate when the ignition switch is in the “on” position.
Reference Instruments in
Sportsfish, Cruisers, Yachts Owner’s Manual , page 73. Not all boats are
equipped with the same type of instrumentation. Consult your dealer for specific information on
the type of instrumentation included on you boat.

PEEDOMETER
• Battery Voltage Indicator
This feature indicates the battery charge when the engine is off and indicates the alternator
output when the engine is running. A reading of 12 or 13 volts is normal indicating a fully-
charged battery. Readings below 11 indicate a weak battery which may not start the engine. A
reading of 13 to 15 volts when the engine is running is normal. Readings over 15 volts may
indicate regulator problems. Low or fluctuating readings may indicate loose connections or
trouble in the regulator and alternator circuit.
• Clock
This feature is battery powered and may need to be reset if the battery select switch is turned
to the "off" position.
• Fuel Meter
This feature indicates the gas tank fuel level. When reading this gauge remember two things:
• The accuracy of your gauge varies with the attitude of your boat in the water (trim or list)
• The fuel pickup tube inside the gas tank is not capable of withdrawing all of the fuel from
the tank.
For these reasons never operate your boat at extremely low fuel levels.
• Low Fuel Warning Indicator
This feature indicates when the fuel level in the main fuel tank is becoming low.
