Power up: Each gauge will power up when the ignition is turned on.
Gauges will stay on as long as the ignition is on.
Lights: The brightness and contrast are adjustable.
Buttons: The MODE button is used for selecting information screens.
The “+” and “–” buttons are used for setting engine speed during troll
control and setting gauge calibrations.
Troll Control: Allows the operator to set and control the idle speed
of the engine for trolling without using the throttle.
Engine Guardian System: Monitors the critical sensors on the engine
for any early indications of problems. The system will respond to a
problem by reducing engine speed in order to maintain a safe operat-
ing condition.
Warning System: The system will sound the warning horn and display
the warning message.

AUTO-DETECTION ENGINE FUNCTION
On first time power up of gauge or after a “Master Reset”, gauge will
display “Auto detect”. Upon pressing the mode button, gauge will au-
tomatically determine engine type. This will preset the data monitoring
screens accordingly. The intention is to make initial setup easier.
If the gauge shows a warning of “No Starboard Engine” or “Multiple
Starboard Engines”, engine location must be properly selected (Port
and Stbd) at the engine using a Mercury engine diagnostic tool. “Mas-
ter Reset” and “Auto detect” again. (Refer to “Master Reset”).
System tach and speed come standard with an “Engine Auto–
detection Screen” this screen lets the gauge on its initial power up
automatically detect which engine type you are using and configure
the gauge to match that vessel type.

6
MASTER RESET
You can return the gauge back to factory presets through the Master
Reset command.
IMPORTANT: Performing a master reset will reset the unit back
to all factory defaults, thus eliminating any installation calibra-
tions performed during set up of product.
By pressing TROLL
–and TROLL +simultaneously for approximately 10
seconds (Until the graphic bars “collide”), you will be able to restore
the unit back to factory presets.

NOT ALL SCREENS MAY APPLY TO YOUR ENGINE TYPE.
When the ignition is turned on, the speedometer will show the last
screen that was displayed before the ignition was turned off.
Press MODE to change display screens. You can revert back to the
previous screen by pressing and holding MODE for 2 seconds. This
will reverse the display rotation.

to Calibrations.
NOTE:Descriptions are not necessarily in order on the gauge. Order
changes depending on engine type.
1. Clock - Temp –Clock, air temperature and water temperature.
The air and water temperature sensors will have to be connected
to obtain display readings.
2. Fuel Level – Displays the amount of fuel remaining.
3. Oil Level – Displays the amount of engine oil remaining, or wa-
ter/waste tank level (if attached).
4. RPM Synchronizer – Dual Engines Only – Monitors the revolu-
tions of both engines.
5. Trim Synchronizer – Dual Engines Only – Displays the trim posi-
tion of both engines. Simplifies keeping trim levels equal.

6. Range – The estimated range is based on boat speed, fuel con-
sumption and fuel remaining in the tank. The numbers displayed
indicates an estimate of the distance you can travel with the re-
maining fuel. Speed input required (Paddle Wheel, Pitot Pressure
or GPS).
7. Fuel Economy – The display shows average “AVG” fuel con-
sumption as well as Instantaneous “INST” fuel economy. The
numbers displayed indicate miles per gallon “MPG” or kilometer
per liter “KM/L”.
Fuel Reset – To reset, select the display screen and press
MODE and TROLL
–buttons.
8. Trip Odometer – Tells how far you’ve gone since you last reset the
gauge to zero. Trip Reset – To reset, select the display screen and
press MODE and TROLL
–buttons.
9. Digital Speedometer – Can display boat speed in miles per
hour, kilometer per hour, or nautical miles per hour. The
speedometer will use the paddle wheel for its low speed read-
ings but will switch to the speedo or GPS (if connected) for high
speed readings. (Transition point setting is described in Cal2).
10. Steering Angle – Shows the relative position of the steering
system. Available on Mercury MerCruiser models only. A steer-
ing angle sensor must be installed on the engine.

temperature and pressures are operating properly.
3. Temperature – Displays engine coolant temperature.
4. Power Trim Angle – Displays trim angle of the outboard or
sterndrive up to the maximum trim angle, and then displays the
trailer angle. 0 = down, 10 = maximum trim, and 25 = full trailer.

Basic Operation
NOTE:Troll control may not be available on all engine models.
NOTE:Troll control min/max range may change depending on en-
gine type.
You can set the troll control by using either the tachometer or
speedometer. Tachometer will set the speed in RPM and speedom-
eter will set the speed in MPH, Kph or KN.
You can shut off troll control anytime by pushing the MODE button
when in the troll display screen or by moving the throttle.
If you have troll control set at a desired speed and then you shut off
the troll control, the system remembers the set speed and will return
to that speed when re-engaged.
The display screen will revert back to the previous screen after 10 sec-
onds of no activity. Push the TROLL
+or TROLL –button to reactivate the
display screen.
When the troll control is engaged and you are out of the troll control
screen, a flashing signal “TR” will appear in the upper left corner of the
display to indicate troll control is still running.

Alarms Warnings – When a problem is detected, the name of the
offending alarm appears on the display (a).
If problem can cause immediate engine damage, the Engine Guardian
System (b) will respond to the problem by limiting engine power. Imme-
diately reduce throttle speed to idle and refer to the warning messages
on the following pages. Refer to the Engine Operation, Maintenance
and Warranty Manual for further explanation of the problem and the
correct action to take.
The alarm message will stay displayed until the mode button is
pressed. If there are multiple alarms, these will cycle on the display at
five-second intervals.

port location using a DDT or Quicksilver Diagnostic Tool.
15. MULTIPLE STARBOARD ENGINE – SmartCraft Gauges are
recognizing multiple engines as starboard.
In multiple engine applications, each engine must first be assigned a
position (starboard, port, starboard2 or port2) with a Quicksilver Diag-
nostic Tool before the system will function properly.
If you have a dual engine application, you must first program the port
engine with a Quicksilver Diagnostic Tool.
16. OIL TEMPERATURE – Engine oil is overheating.
