Keys
The engine key is unique to just the lock at the helm, it doesn’t work in any
other lock. When not underway, we recommend you remove the key and
place it in the starboard aft corner of the map table drawer. A spare engine
key is stowed with the spare engine parts in a marked plastic bin on the
starboard side of the engine room.
Engine Alarms
The engine is managed and monitored by an Electronic Control Module (ECM
computer). The ECM has numerous sensors for various engine parameters
and uses those to create any cautionary or warning alarms. The Mercury LCD
display at the helm is the visual screen for the ECM. In normal circumstances,
the display shows various engine parameters such as RPM, oil pressure,
temperature, etc. It will announce and sound an aural tone if any parameter
or condition warrants action.
Cooling Water Alarm
A cooling water flow alarm is installed which
will alarm any time cooling water flow is
interrupted or reduced for any reason, due to
an intake blockage, impeller failure, etc. If this
unit sounds an alarm it is imperative to STOP
the engine immediately to avoid major damage
to the engine and systems, and to immediately
investigate the cause. The most likely cause
will be a water flow blockage caused by eel
grass or other ingested material, which can be
identified in and removed from the glass water
strainer unit in the engine room (Portside front
bulkhead – see picture on page 21). NOTE: The cooling water alarm will
sound when you turn the ignition key until you start the engine, as there is
no water flow until the engine is running. To avoid the irritating alarm sound
while starting, you can depress the red mute button at the bottom of the
helm station until the engine has started.
