CAUTION
To avoid possible ingestion of water that can damage engine components:
• Do not turn the ignition key off when the engine is running above idle speed.
• Do not use the lanyard stop switch to shut off the engine above idle speed.
• When coming off plane, if a large following wave may roll over the boat’s transom, apply a short,
light burst of throttle to minimize the wave action against the stern of the boat.
• Do not come off plane quickly, shift into reverse and shut off engine.

8.1L Engine Guardian Strategy
IMPORTANT: Boat speed could be reduced to idle and may not respond to throttle.
Engine Guardian Strategy is designed to help reduce the potential for engine damage by reducing engine power
when a potential problem is sensed. Engine Guardian monitors:
• Oil Pressure
• Coolant Temperature
• Sea Pump Pressure
• Exhaust Manifold Temperature
For example, if one exhaust manifold’s water cooling passages become partially blocked, Engine Guardian
Strategy will reduce the power level of the engine to bring the temperature on that manifold back into the normal
operating temperature range. If the debris passes through and full water flow is restored, engine power levels
are restored back to normal. In other words, Engine Guardian Strategy is a looped feedback or smart system.
