OBDM
If an OBDM fault is detected, the audio warning system sound with one five‑second horn, then one short, 1/2‑second horn every
60 seconds for certain faults related to the emissions control or fuel systems. See your authorized Mercury MerCruiser dealer for
assistance.

Testing The Audio Warning System
1. Turn the ignition switch to the "ON" position without cranking the engine.
2. Listen for the audio alarm. The alarm will sound if the system is functioning correctly.
Engine Guardian Strategy
IMPORTANT: Boat speed could be reduced to idle and may not respond to the throttle.
Engine Guardian Strategy is designed to help reduce the potential for engine damage by reducing engine power when a potential
problem is sensed by the ECM. Engine Guardian monitors:
•
Oil pressure
•
Coolant temperature
•
Seawater pressure
•
Engine overspeed
•
Exhaust Manifold Temperature [8.1 liter (496 cid) engines only]
Also the Engine Guardian Strategy will reduce engine power to 90 percent of maximum if any sensor on the power package fails.
For example, if the water inlet becomes partially blocked, Engine Guardian Strategy will reduce the available power level of the
engine to help prevent damage from decreased water flow to the engine. If the debris passes through and full water flow is restored,
engine power levels are restored to normal.
To avoid a possible recurrence of the problem you should contact an authorized dealer. The ECM stores the fault and with this
information the technician will be able to more rapidly diagnose problems.
Axius Premier Features (If equipped)
Axius Premier Precision Pilot Trackpad Functions
The Axius Premier System is a fully integrated system utilizing a GPS sensor, a customer‑supplied NMEA‑0183–compatable
chart‑plotter, an inertial measurement unit (IMU), the electronic helm, Vessel View, joystick control, and the Axius Premier trackpad
provided with the system. No third‑party autopilot is necessary.
Axius Premier requires the following:
•
A CAN based NMEA‑0183 information stream from the GPS unit
•
A Mercury approved chartplotter
•
An inertial measurement unit (IMU)
•
The electronic helm
•
VesselView
The Axius Premier Precision Pilot Trackpad gives the operator control over:
•
SkyHook
—allows the boat to hold its position without lines or anchor
•
Response
—compensates for the effects of wind, waves, and currents on the boat's direction.
•
Auto Heading
—controls the boat on a pre‑determined heading
•
Track Waypoint
—controls the boat on a pre‑determined path with a single waypoint
