Guardian Strategy
The Mercury Engine Guardian system reduces the potential for engine damage by restricting engine power when the control
module detects a potential problem. Below are some examples of what Engine Guardian monitors:
•
Oil pressure
•
Engine coolant temperature
•
Low coolant level
•
Seawater pressure sensor
•
ECM malfunction
•
Crankshaft speed sensor
•
Camshaft sensor
•
Boost pressure
•
Fuel pressure
•
Air temperature
•
Oil temperature
•
Fuel temperature
•
Exhaust gas temperature
IMPORTANT: Engine Guardian can reduce power anywhere from 100% to idle, depending on the severity of the problem. If
forced to idle, boat speed might not respond to throttle operation.
The control module stores the fault for diagnostics. For example, if the water inlet becomes partially blocked, Engine Guardian
reduces 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 Guardian restores engine power to normal.
