Audible Alarms

Most Mercruiser and Volvo engines use audible alarms. They are
designed to use sensors which pick up deviations from the normal
operating parameters. Oil pressure and temperature sensors send a signal
to a buzzer under the dash which sounds a high pitched alarm indicating
a possible problem. In addition to the dash, some engines use buzzers
at the engine itself.
NOTICE
PREVENT POSSIBLE ENGINE DAMAGE
WHEN AN AUDIBLE ALARM SOUNDS
SHUT DOWN ENGINE IMMEDIATELY,
INVESTIGATE & REPAIR THE PROBLEM
On start up it is not unusual to hear an audible alarm sound when
cranking the engine over. This occurs normally because it takes a second
or two to build up the engine oil pressure. Then the alarm will stop.
A seasoned skipper monitors his instrument panel often while cruising.
Instrument Lighting
Each gauge is designed with a light bulb so it can be seen at night. On
most models you activate the instrument lighting by energizing the
navigation light switch. Eliminate condensation inside the gauges by
activating the gauge lights in high humidity environments.
