OVERVIEW
The Mercury controller is a navigation tool that automatically keeps vessels equipped with a Mercury
Marine engine at a steady speed via cruise or troll control modes.
SAFETY
⚠WARNING: An engine controller is a useful navigational aid, but it does not replace
a human navigator. Ensure the system has been installed correctly, commissioned and
calibrated before use.
Do not use cruise/troll control when in:
• Heavy marine trac areas or narrow waters.
• Poor visibility or extreme sea conditions.
• Areas where use of a cruise control system is prohibited by law.
When using the cruise/troll control:
• Do not leave the helm unattended.
• Do not place any magnetic material or equipment near the heading sensor used by the autopilot
system.
• At regular intervals, verify the course and position of the vessel.
• Reduce speed in time to avoid hazardous situations.
REQUIREMENTS
To view the Mercury controller, you need the following:
• NSX MFD with software version 1.3.257 or later.
• A fully installed and commissioned Mercury engine. Up to four engines are supported.
• A correctly congured Mercury SmartCraft Connect module.
Refer to the Mercury Marine SmartCraft Connect website for further information.
¼NOTE: Contact Mercury for all information on hardware and installation procedures. We recommend
professional installation of your Mercury engine, SmartCraft Connect gateway, and helm assignment.

MERCURY CONTROLLER
A

E
A Mercury controller – use to show/hide the controller.
B Active Trim – use to turn on/o the active trim feature to enhance vessel performance and stability.
C Cruise control – use to set a speed limiting function at higher engine RPMs.
D Troll control – use to set a speed limiting function for use at slower speeds.
E Sport exhaust – use to turn activate the sport exhaust mode on compatible Mercury engines.
¼Note: You can start and stop cruise control or troll control directly from this panel by pressing Cor D.
¼Note: The Mercury controller and options within the controller are only visible and enabled when the
suitable hardware is congured on the vessel via the SmartCraft Connect gateway.

6
CRUISE CONTROL
Cruise control is a speed limiting function which can be activated above trolling speed. The minimum and
maximum engine RPM should be congured by your engine and/or SmartCraft Connect installer.
¼NOTE: Cruise control can only be engaged in F (Forward) or R (Reverse) throttle positions.
Engage cruise control
Follow these steps to engage cruise control when it is safe to do so.

1 Engage F (Forward) or R (Reverse) to the desired the RPM.
2 Select the cruise control RPM button (A).
3 Use the +/- buttons (B) to set the cruise control target RPM (E). Select and hold to change the RPM
rapidly.
4 Select START (C) to engage cruise control.
5 Move your throttle to match the cruise control target RPM. You can check the current engine RPM via
the gray sweep indicator or engine RPM display (F).
6 Active is displayed when the engine has reached the target RPM.
7 Once active, you can adjust the cruise control RPM via the +/- buttons (B).
¼Note: If you move the throttle position beyond the cruise control target RPM, you may experience a
momentary surge, but the cruise control system will rapidly match the engine RPM to the target RPM.
⚠WARNING: When you need to slow down in an emergency, lower the throttle position to
override the cruise control. If you need to exceed the cruise control target RPM, select STOP
(D) to disengage cruise control before increasing your throttle input.
Disengage cruise control
Your engine will maintain the target RPM until cruise control is disengaged or the throttle position is
reduced below the cruise control target RPM.
To disengage cruise control select STOP (D) then move the throttle to neutral or idle position.

7
TROLL CONTROL
Use troll control as a low-speed engine RPM limiter when shing, surveying, navigating a busy harbor/
speed restricted area/no-wake zone, or when your maximum vessel speed must be lower than the
minimum cruise RPM.
The minimum and maximum troll control RPM should be congured by your engine and/or SmartCraft
Connect installer. The values for minimum and maximum limits are provided by the gateway, for both
cruise and troll. Correct conguration of the gateway is required for these values to be correct on the
MFD.
¼NOTE: Troll control can only be engaged with the throttle in the forward idle position, and engine RPMs
are controlled via the Mercury engine controller.
Engage troll control
Follow these steps to engage troll control when it is safe to do so.

5 Once active, you can adjust the troll control RPM via the +/- buttons (B).
6 Select STOP (D) to disengage troll control.
¼Note: Troll control is disengaged when the throttle position is changed.
Disengage troll control
Troll control can be disengaged by selecting STOP or changing the throttle position.

ACTIVE TRIM
Active Trim is an integrated GPS, speed-based automatic engine trim system from Mercury Marine. This
system continually adjusts engine trim based on changes in boat speed to improve performance, fuel
economy, and ease of operation.
Active Trim should be congured by your engine and/or SmartCraft Connect installer.
Engage Active Trim
Follow these steps to engage Active Trim when it is safe to do so.

1 Put the throttle into gear.
2 Select Active Trim (A).
3 Select +/- buttons (B) to change an Active Trim prole (set up by your installer).
4 Select ON (C) to engage Active Trim.
5 Select OFF (D) to disengage Active Trim.
¼Note: Active Trim can only be engaged when the throttle is in gear.
Active Trim behavior
As the boat accelerates, the engine will trim out, and as the boat decelerates (E.g. when making a turn),
the engine will trim in.
Follow the prompts and alerts, and take necessary action where required.
¼Note: Active Trim allows the boat operator to compensate for changes in boat load, driver preferences,
and weather conditions while maintaining full automatic control. Use the manual trim buttons at any
time to override Active Trim.

9
SPORT EXHAUST
Selected Mercury engines are equipped with a sport exhaust feature which makes the engine exhaust
note sound louder and deeper at idle and low speeds.
Select Sport Exhaust to toggle between quiet operation and a ‘throatier’-sounding sport mode.
¼Note: The Sport Exhaust button is enabled only when the Mercury engine has a sport exhaust feature.

10
ENGINE MESSAGES
Your multi-function display presents maintenance and warning messages generated by the Mercury
Marine engine.
¼Note: Consult the Mercury Marine engine operator manual or an authorized Mercury Marine engine
specialist to resolve the displayed issue.
