CHAPTER 3
Audible Alarms
The engines use audible alarms. They are designed to use sensors which
pick up deviations from the normal operating parameters.
Always shut off the engine when an audible alarm sounds to
prevent possible engine damage. Investigate and repair the
problem before starting the engine.
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.
Refer to the engine manufacturer's operation manual for additional
information.
Ignition Switch
Each ignition switch features 3 positions. In a clockwise direction they
are off, run, and start. The start position is spring loaded and the key
should be held in this position to engage the starter. Once the engine
has started release the key from the start position. The electrical system
will then be energized in the run position.
Be a smart skipper and remove the ignition keys from the ignition
switches with children aboard and/or when there are people in the
water.
