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.
Relative adjustments can be made by bending the fuel
sender float arm.
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 F Fuel System for additional informa-
tion.
G. Power Trim Gauge
The Power Trim Gauge provides a visual indication of the
inward-outward (trim angle) position of the outdrive.
H. Depth Gauge
The Depth Gauge is standard equipment on the Vista
models. The depth gauge on the 238 & 258 Vistas will
read depth only and cannot be adjusted. It is installed in
the dash module.
I.
Gas Vapor Detector
The Gas Vapor Detector is optional equipment on the
278 Vista only. The gauge will mount in the dash. Addi-
tional information can be found in Section F-1h in this
manual.
J. Engine Hour Meter
Engine hour meters are available on all Vista models and
provide a numeric record of elapsed engine operating time.
This information is important in determining scheduled
maintenance intervals, ships log data, cruise information,
etc. If so equipped, the hour meter will be located in the
engine compartment.
K. 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
battery(s). Additional information on ignition switch op-
eration is covered in Section Q Operation, of this manual.

L. Emergency Ignition Shut-Off
The emergency ignition shut-off switch is provided on most
models. If equipped, the switch has a lanyard (cord) at-
tached to a clip which must be in position for the en-
gine(s) to run. See Figure B6. The helmsman can at-
tach the cord to a belt loop, life jacket, etc. If the clip is
not in position, the starter and other systems will still
operate but the engine will not start. Should the op-
erator move beyond the range of the lanyard, the engine(s)
will be shut off preventing the boat from becoming a run-
away. If the lanyard is too long, it can be shortened by
knotting or looping it. DO NOT cut and retie the lanyard.
NOTICE
DO NOT attach the lanyard to clothing that will
tear away before the lanyard is pulled from the
switch to stop the engine.
Figure B6: 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 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.
