• Engine overspeed
• Exhaust Manifold Temperature (8.1 and 496 models 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.
Transmission Guardian Strategy
IMPORTANT: Boat speed could be reduced to idle and may not respond to the throttle.
Transmission Guardian is a MerCruiser DTS feature that protects transmissions from
clutch damage. Transmission Guardian monitors the clutch pack pressure in forward and
reverse gears. If the transmission fluid pressure drops below a predetermined level,
Transmission Guardian lowers the engine torque and speed to prevent clutch slippage.
To avoid 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.
Warning Horn Signals
Most faults will cause the warning horn circuit to activate. How the warning horn activates
depends on how serious the problem is. There are four warning horn states:
• Caution ‑ horn signal varies with product line and calibration. Minimal guardian.
• Warning ‑ horn signal varies with product line and calibration.
• Severe ‑ horn is beeping constantly.
• Critical ‑ horn is beeping constantly and guardian will be at forced idle.
In addition, depending on the gauge package, there will be warning icons and fault
messages on the dash mounted gauges.
