Avoid knocking or pulling the clip or lanyard from
the switch during regular boating operation. Occu-
pants may be thrown forward or possible engine
damage may occur by the sudden loss of engine
power.
M. Alarm Systems
Engine alarm systems are installed on some models with
specific types of engines. This is an audible alarm that is
mounted in the helm area; it is actuated by engine water
temperature and engine oil pressure senders. The alarm
will sound in the event of low engine oil pressure or high
engine coolant temperature.
The engine alarm will sound during engine start-up, or
whenever the ignition switch is positioned to ON and the
engine is not operating. The alarm sounds under these
conditions because engine oil pressure is low; the alarm
will cease to sound as soon as engine oil pressure rises
to the proper level.
NOTICE
The engine alarm system installed in Four Winns
boats monitors only engine water temperature and
engine oil pressure. Always maintain a close
visual watch on the drive(s), transmission(s), en-
gine fluid levels, bilge water level, etc. Refer to
the engine manufacturer's literature for additional
information.
N. Instrument Maintenance
Electrical protection for instruments and ignition circuitry
is provided by a fuse or circuit breaker on the instrument
panel.
Periodically, spray the ignition switch(s) with a contact
cleaner. The ignition switch(s) and all instruments, con-
trols, etc. should be protected from the weather when not
in use. Four Winns offers appropriate weather covers for
each model. Excessive exposure can lead to gauge and
Ignition Switch difficulties.
Electronic gauges are affected by static electricity that
builds-up on the glass face. Periodic washing of the gauge
face with warm water and mild liquid detergent will help
eliminate the static electricity problem and improve gauge
accuracy.
