H. Gas Vapor Detector
A gas vapor detector is optional equipment on the
258 and 278 Vista
®
. If equipped, the gauge mounts in
the dash. Additional information can be found in
Section I-1H - Gas Vapor Detector in this manual.
I. Engine Hour Meter
Engine hour meters are standard on the 258 and 278
Vista
®
models and provides a numeric record of
elapsed engine operating time. This information is
important in determining scheduled maintenance
intervals, ships log data, cruise information, etc. The
hour meter is located at the helm with the tachometer/
hour meter combination gauge.
J. Ignition Switch
The ignition switch has three positions: OFF, RUN,
and START. The START position is spring loaded
and the key should be held in this position until the
engine starts. The key will return to the RUN position
once released. Always turn the key to the OFF
position when the engine is not running. This will
prevent discharging of the batteries. Additional
information on ignition switch operation is covered
in Section A - Operation of this manual.
K. Emergency Stop Switch
This safety device automatically stops the engine if
the lanyard is attached to the operator and the
operator falls from his work station. Refer to the
engine manual for detailed information about using
this switch.
The emergency stop switch (Figure E-8) 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 ob-
structions 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 engine can be started.
NOTICE
Operation of an engine with abnormally low
oil pressure can lead to engine damage and
possible seizure. Have the engine serviced
immediately upon a reduced oil pressure
indication.
E. Voltmeter
The voltmeter monitors battery condition and thus
alternator performance. See Section H - Electrical
Systems for additional information on voltmeter
operation.
F. Fuel Gauge
The fuel gauge displays the level of fuel that is present
in the fuel tank. Refer to Section I - Fuel System for
additional information.
Due to the mechanical nature of the fuel sender, varia-
tions in readings during various speeds of operation
may occur. This system is merely a relative indication
of the available fuel supply and not a calibrated
instrument. Refer to Section I-1F - Fuel Senders for
additional information.
NOTICE
Fuel gauges are not precision instruments.
The reading is relative, and should never
be relied upon as the sole indicator of fuel
availability.
NOTICE
Use only clean, dry fuel of the type and grade
recommended by the engine manufacturer.
The use of incorrect or contaminated fuel
can cause engine malfunction and serious
damage. Refer to Section I - Fuel System
for additional information.
