Four winns Vista 328 Owner's Manual page 47

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 comes standard on a 298 Vista® and a
speedometer is not available on the 328 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
Speedometers are not precision instruments. The
indications are relative and should never be used
for navigational purposes or similar critical situa-
tions alone. Use other navigation systems in
conjunction with the speedometer.
NOTICE
DO NOT rely on the speedometer 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 H - Electrical Systems
and 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.
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 I - Fuel System for additional informa-
tion.
G. Power Trim Gauge
The trim angle is how far in or out the drive is positioned
in relation to the bottom of the boat. The power trim gauge
provides a visual indication of the inward-outward (trim
angle) position of the outdrive. The trim angle of the drive
or outboard engine has a distinct affect on the running
angle of the boat. See Sections E-6 and E-7 for addi-
tional information regarding running angle.
H. Depthsounder
The depthsounder is standard equipment on your 298/
328 Vista . It consists of two main components, the
transducer and the HDR 600 unit. The transducer is
mounted to the hull and the HDR 600 is installed in the
dash. The transducer and HDR 600 communicate by
means of a cable, and are powered by your boat’s 12-
volt DC battery. The transducer and HDR use the basic
principle of sonar to indicate the water’s depth. Please
