Engine Synchronizer Gauge; Alarm System - Four winns 248 Vista Owner's Manual

The emergency stop switch (Figure E11) incorporates a
shutoff switch, switch clip, lanyard, and lanyard clip.
The lanyard clip must be securely attached to the
operator's PFD, clothing, arm, or leg. Be sure to attach
the lanyard to a place where it is free of obstructions
and to something that will move with the operator if he or
she leaves the helm station. If the engine shuts down
because this switch was activated, the clip may have to
be reinstalled on the interrupter switch before the en-
gine can be started.
Keep emergency stop switch lanyard free from
obstructions that could interfere with its opera-
tion. Do not modify or remove emergency stop
switch or bypass its safety features. The proper
use of the emergency stop switch will prevent a
runaway boat situation which can cause severe
personal injury or death.
Figure E11: Emergency Stop Switch
The emergency stop switch can only be effective when in
good working condition. Observe the following:
1. Lanyard must always be free of entanglements that
could hinder its operation.
2. Once a month, check the switch for proper opera-
tion. With engine running, pull lanyard. If the engine
does not stop, see your Four Winns dealer.
3. Once a month, inspect both the clip and lanyard for
cuts, breaks or wear. Replace worn or damaged parts.
In an emergency situation, any occupant of the boat can
restart the engine. Just press in and hold the emergency
stop switch button, then follow normal starting procedures.
When the button is released, the engine will stop.

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 en-
gine power.
M. Engine Synchronizer Gauge
An engine synchronization gauge is available on certain
Vista™ models with twin engine propulsion. It is usu-
ally located between the tachometers on the dash. This
instrument compares the electrical signals generated by
the engines and converts those signals to a visual meter
indication of engine speed difference. The meter move-
ment responds to changes in throttle position.
This instrument does not physically synchronize the en-
gines, but only provides a visual indication so the opera-
tor can take corrective action. See Section F-2 - Control
Operation and the engine manufacturer's literature for addi-
tional information on throttle usage and engine synchro-
nization.
N. Alarm System
Vista™ models, either gas or diesel, have an engine
alarm system installed. 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 monitors only engine water tem-
perature and engine oil pressure. Always main-
tain a close visual watch on the drive(s), transmis-
sion(s), engine fluid levels, bilge water level, etc.
Refer to the engine manufacturer's literature for
additional information.
