NOTICE
Operation of an overheated engine can result
in engine seizure. If an unusually high tempera-
ture reading occurs, shut the engine off imme-
diately.
D. Oil Pressure Gauge
The oil pressure gauge indicates the pressure in the
engine lubrication system. A drop in oil pressure is a
possible indication of oil pump or leakage problems. If
the oil pressure drops below 6 PSI (pounds per square
inch), a single beep will sound every 2 seconds and
the oil telltale will illuminate on the 210 Horizon-265
Sundowner dash module.
NOTICE
Operation of an engine with abnormally low oil
pressure can lead to engine damage and pos-
sible seizure. Have the engine serviced imme-
diately upon a reduced oil pressure indication.
E. Voltmeter
The voltmeter monitors battery condition and thus alter-
nator performance. See Section H for additional infor-
mation regarding electrical systems.
On the 210 Horizon-265 Sundowner cluster, the volt-
meter indicates the voltage at the cluster. If the volt-
age is below 10 or above 16 VDC (volts of direct cur-
rent) while the engine is running the telltale will light,
and the cluster will beep every 2 seconds.
F. Fuel Gauge
The fuel gauge displays the level of fuel that is present
in the fuel tank. The fuel gauge will operate when the
ignition switch supplying power to the fuel gauge is in
the RUN position. At 1/6 of a tank, a low fuel warning
light will appear on the module.
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 your Four Winns®
dealer by bending the fuel sender float arm. Refer to
Section I-1E Fuel Senders for additional information.
NOTICE
Use only clean fuel of the type and grade recom-
mended by the engine manufacturer. The use
of incorrect or contaminated fuel can cause en-
gine malfunction and serious damage. Refer to
Section I Fuel Systems for additional informa-
tion.
G. Power Trim Gauge
Boats equipped with stern drives also have a power
trim gauge. This gauge provides a visual indication of
the inward-outward (trim angle) position of the outdrive.
There is not a trailer travel mode on the gauge.
H. Depthsounder - 280 Horizon & 285 Sundowner
The depthsounder is standard equipment on your 280
Horizon and 285 Sundowner. 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 com-
municate by means of a cable, and are powered by
your boats 12-volt DC battery. The transducer and HDR
use the basic principle of sonar to indicate the waters
depth. Please read the manufacturers literature in-
cluded with the owners packet for information regard-
ing operation and maintenance.
1. Control Functions
The HDR 600 uses a blacklit 7-segment display in con-
junction with a 3-button keypad to control all user func-
tions. At initial power up, the unit will begin normal op-
eration and display the digital depth and the units of
measure. Figure E7 shows a typical view you might
see on-screen at initial power-up.
Figure E7: Depthsounder (HDR 600)
The HDR600 uses 3 buttons to control the Shallow
Alarm, Deep Alarm, Keel Offset and Units of Measure
function. While in normal operation, pressing the SET
button selects a Function and blinks its corresponding
indicator on the display. Once a Function has been
selected it may be adjusted by pressing the UP and
DOWN arrow buttons to adjust the setting. Further
presses of the SET button will sequentially select the
