Mercury Racing 500R - Warning System

Warning System
WARNING HORN SIGNALS
When the key switch is turned to the ON position, the horn will turn on for a
moment as a test to indicate the horn is working.
There are two types of warning horns to alert the operator of an active problem
within the engine’s operating system.
1.
Continuous six second beep: Indicates a critical engine condition.
Depending on the condition, the Engine Guardian system may engage
and protect the engine by limiting power. You should return to port
immediately and contact your servicing dealer.
2.
Intermittent short beeps for six seconds: Indicates a noncritical engine
condition. This condition does not require immediate attention. You may
continue using your boat, however, depending on the nature of the
problem, the engine’s power may be limited by the Engine Guardian
system. Refer to Engine Guardian System. You should contact your
servicing dealer at your earliest convenience.
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 fuel filter. Replace the filter. Refer to
Maintenance ‑ Boat‑Mounted Fuel Filter.
• 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.
