NOTICE
Never exceed the maximum recommended
operating RPM of your engines. Maintaining
maximum, or close to maximum RPM for ex-
tended periods can reduce the life of the engines.
Some engines are equipped with devices that limit en-
gine rpm in accordance with the oil pressure or engine
temperature. Refer to the Engine Owner's manual for
additional information.
B. Speedometer
A speedometer is not available on the 348 Vista. With
the optional GPS/Navigational package the ability to
monitor your speed becomes available. Please refer to
the manufacturer’s information on how to program the
Nav 398 for speed readings. This information is included
in the owner’s packet when the boat is order with the
navigation package. If the navigation package is ordered
later the manufacturer’s information will be included.
NOTICE
Speed indicators are not precision instruments.
The indications are relative and should never be
used for navigational purposes or similar critical
situations alone. Use other navigation systems
in conjunction with the speedometer.
NOTICE
DO NOT rely on the speed indicator when trying
to achieve a “NO WAKE” condition in a harbor or
other enclosed waterway. ALWAYS be cogni-
zant of the size of your waves your boat is mak-
ing and reduce throttle until you are sure that
they will not cause any damage. You are
responsible for damage caused by the wake of
your boat.
C. Temperature Gauge
The temperature gauge monitors the cooling system of
the engine. A sudden increase in the temperature could
be a signal of a blocked cooling passage or a water pump
malfunction.
NOTICE
Operation of an overheated engine can result in
engine seizure. If an unusually high tempera-
ture reading occurs, shut the engine off immedi-
ately.

D. Oil Pressure Gauge
The oil pressure gauge indicates the pressure in the en-
gine lubrication system. A drop in oil pressure is a pos-
sible indication of oil pump or leakage problems.
NOTICE
Operation of an engine with abnormally low oil
pressure can lead to engine damage and pos-
sible seizure. Have the engine serviced immedi-
ately upon a reduced oil pressure indication.
E. Voltmeter
The voltmeter monitors battery condition and thus alter-
nator 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 E - Engine and Drive
Systems and Section I - Fuel System for additional infor-
mation.
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
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 informa-
tion.
G. Depthsounder
The depthsounder is standard equipment on your 348
Vista . It consists of two main components, the trans-
ducer and the display unit. The transducer is mounted
to the hull and the display unit is installed in the dash.
The transducer and display unit communicate by means
of a cable, and are powered by your boat’s 12-volt DC
