B. Speedometer
A speedometer is not be available on the 338 Vista
models. With the optional GPS/Navigational package
the ability to monitor your speed becomes available.
Please refer to the manufacturer's literature for
programming the GPS unit for speed readings. This
information is included in the owner's packet when the
boat is ordered with the navigation package.
NOTICE
Speedometers/speed indicators are not
precision instru ments. The indications are
relative and should never be used for naviga-
tional purposes or similar critical situa tions
alone. Use other navigation systems in con-
junction 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 water way. ALWAYS
be cognizant of the size of your waves your
boat is making and reduce throttle until you are
sure that they will not cause any damage. You
are responsi ble for damage caused by the
wake of your boat.
Engines, Drives and Instrumentation - Section E
C. Temperature Gauge - (Included in 4-in-1
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. See Figure E5.
Operation of an over heat ed en gine can re sult
in en gine sei zure. If an un usu ally high tem pera-
ture read ing oc curs, shut the en gine off
im me di ately.
D. Oil Pressure Gauge - (Included in 4-in-1
Gauge)
The oil pressure gauge indicates the pressure in the
engine lubrication system. A drop in oil pres sure is a
possible indication of oil pump or leakage problems.
See Figure E5.
Operation of an engine with ab normal ly low oil
pressure can lead to engine dam age and
possible seizure. Have the en gine ser viced
immediately upon a reduced oil pressure
®
indication.
E. Voltmeter - (Included in 4-in-1 Gauge)
The voltmeter monitors battery condition and thus
alternator performance. See Section H - Electrical
Systems for addi tional information on voltmeter
operation. See Figure E5.
F. Fuel Gauge - (Included in 4-in-1 Gauge)
The fuel gauge displays the level of fuel that is present
in the fuel tank. Refer to Section I - Fuel System for
additional infor mation. See Figure E5.
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 avail able fuel supply and not a calibrated
instru ment. Refer to Sec tion I-1F - Fuel Senders for
additional information.
