It is important to note that in either of the above scenarios, the horn will only
sound one time. If you key the engine off and restart it, the horn will sound
again, one time, if the fault is still present. For visual display of the specific
engine functions and additional engine data, refer to
SmartCraft Product
information, following.
A few of the noncritical conditions indicated by the intermittent short beeps for
six seconds can be corrected by the operator. These operator correctable
conditions are as follows:
•
Water in the boat mounted water separating fuel filter (optional
accessory). Refer to the instructions supplied with the accessory kit.
•
Cooling system (water pressure or engine temperature) problem. Stop the
engine and check the water intake holes in the lower unit for obstruction.
•
Low engine oil level. Refer to
Fuel and Oil – Checking and Adding
Engine Oil
.
ENGINE GUARDIAN SYSTEM
The Engine Guardian system monitors the critical sensors on the engine for
any early indications of problems. Engine Guardian is functional whenever your
engine is operating, so you never have to be concerned about whether or not
you are protected. The system will respond to a problem by sounding the
warning horn for six seconds and/or reducing engine power in order to provide
engine protection.
If Engine Guardian has been activated, reduce the engine speed. The problem
will need to be identified and corrected. The system must be reset before the
engine will operate at higher speeds. Moving the throttle lever back to the idle
position will reset the Engine Guardian system. If the Engine Guardian system
has determined the reset has not corrected the problem, Engine Guardian will
remain activated, limiting the throttle. The problem must be identified and
corrected before Engine Guardian will allow the engine to reach a normal
operating RPM.
OVERSPEED REV LIMIT
The overspeed rev limit is set at an RPM greater than the operating range. In
the event that the engine is operated at an RPM greater than or equal to the
overspeed limit, the PCM does not allow the engine to maintain the power
requested by the operator. Refer to
Specifications
to determine this engine’s
RPM limit.
Upon reaching the beginning of the rev limit, Engine Guardian will cut‑out the
ignition to specific cylinders. If the operator does not reduce engine speed,
Engine Guardian will cut‑out the ignition to all the cylinders. There is no audible
warning while Engine Guardian overspeed limit is active.
To reset the Engine Guardian protection:
1. Completely reduce the throttle for three seconds.
2. Engage the throttle. If the engine does not respond, repeat step one.
