analog gauges (i.e., Faria), the gauges will light up when the navigation lights are on. If your engine
package includes digital gauges provided by the engine manufacturer (i.e., Mercury SmartCraft, Honda,
etc.), the gauges will light up only when the engine is on.
Note: For boats rigged with analog gauges (i.e., Faria), the gauge configuration may
include individual gauges for the trim, volts and fuel gauges or a multifunction gauge that
includes these 4 gauge functions. For boats rigged with digital gauges, the trim, volts
and fuel gauges are incorporated into the tachometer gauge.
Tachometer - To ensure the tach is working properly, simply turn the ignition key on and start the engine.
While the engine is idling, the tach should be reading in the proper rpm range recommended for the
engine. Your engine manual will indicate the appropriate RPM range. When you are running at wide-
open throttle, the tach should read near the top end of the recommended rpm range.
If the RPM gauge is reading correctly and the engine throttle settings are correct, the tachometer is
operating properly. If the tachometer is not reading correctly, refer to the manual provided by the
manufacturer of the gauge (included in your owner's package).
Speedometer - To ensure that the speedometer (speedo) is working properly, get the boat on a planing
speed and check to see if the gauge is reading at the approximate running speed at which the boat is
traveling.
Note: The speed-reading on the speedo may vary a few mph from the actual speed that
the boat is traveling. Either a GPS or a radar gun can check the running speed.
Trim - To ensure the trim gauges/indicators are working properly, start by making sure the engine is
trimmed all the way down. Locate the trim gauge on the instrument panel and check to see if the level on
the trim gauge is in the full down position. As you trim the engine up, watch the trim gauge and ensure
that it coincides with the actual trim of the engine. When finished trimming the engine all the way up, the
level on the trim gauge should read in the full up position.
Volts - To system check the volt gauge, turn the ignition key on and turn on the engine. With the engine
running, check the reading on the volt gauge. It should be reading between 12 and 14.5 volts. This
reading ensures that the charging system and the volt gauge are working properly.
Fuel - The fuel gauge reads the amount of fuel remaining in the tank. To check the fuel gauge, place a
known amount of fuel into the fuel fill and fill the tank. Turn the ignition key on and the fuel gauge should
read the approximate amount of fuel in the tank.
For example: If the fuel tank holds 240 gallons of fuel and you pumped 60 gallons of fuel
into the tank, the fuel gauge should read approximately ¼ of a tank. This ensures that
the fuel gauge and the fuel sender are working properly.
If the fuel gauge is not reading correctly, we recommend that you have the fuel sender checked by a
qualified professional before considering changing out the gauge. For more information, please refer to
the Fuel/Oil Systems section of this manual.
For specific information related to your gauges, refer to the materials in your owner's package that was
provided by the gauge manufacturer.
