ENGINE MONITORING SYSTEM
The engine monitoring system warns the operator of conditions that could damage the outboard. The system includes sensors on the engine and oil tank, a warning horn, a dash-mounted gauge, and related wiring.
The EMM sends information about monitored functions to:
- An I-Command, or other NMEA 2000 compliant CANbus network
- The SystemCheck Modular Wiring System (MWS)
- EMM LED indicators
IMPORTANT: Outboards with remote controls must be equipped with an I-Command system, a SystemCheck gauge, or an equivalent engine monitor. Operating the outboard without an engine monitor will void the warranty for failures related to monitored functions.
Typical I-Command and SystemCheck gauges
The EMM activates the warning horn and gauge displays as follows:
- LOW OIL means that oil in the tank is at reserve level (about 1/4 full).
- NO OIL indicates the oil tank is empty.
- WATER TEMP or HOT indicates an engine or EMM overheat condition.
- CHECK ENGINE or FAULT is used to indicate other fault conditions identified by the EMM.
Refer to the EMM Service Code Chart at the back of this manual for a complete list of all fault codes.
System Self-Test
During engine start-up, pause with the key switch in the ON position. The horn self-tests by sounding a half-second beep. SystemCheck gauges self-test by turning the indicator lights on simultaneously, then off in sequence.
Service Mode
SystemCheck goes into a service mode if the key is left ON after self-test (engine NOT running). All light circuits and sensors are active, but the horn is not. Grounding the appropriate light circuit wire will turn the light on, but the horn will not sound. Refer to SystemCheck CIRCUIT TESTS on p. 136.
Engine Running
All warning circuits are active when the engine is running. The horn circuit is active when engine speed exceeds 500 RPM.
Engine monitor warnings activate the horn for 10 seconds and the appropriate gauge light for a minimum of 30 seconds. If the failure is momentary (for example, oil moving in the tank), the light will remain ON for the full 30 seconds before going out. If the fault continues, the light remains ON until the key is turned OFF or the failure is corrected. The warning will reoccur at the next start up if the problem is not corrected.
