A. Tachometer
The tachometer indicates the speed of the engine in revo-
lutions per minute (RPM). This speed is not the boat
speed or necessarily the speed of the propeller. The
tachometer may not register zero with the Ignition Key in
the OFF position.
NOTICE
Never exceed the maximum recommended
operating RPM of your engine. Maintaining
maximum, or close to maximum RPM for ex-
tended periods can reduce the life of the engine.
Some engines are equipped with devices that limit en-
gine RPM in accordance with the oil pressure, or engine
temperature. Refer to the engine manual included in the
owner’s packet for additional information.
The tachometer must be set for different engines installed.
This is typically done at the factory with the aid of a
software program for the Four Winns/VDO module.
B. Speedometer
The electronic speedometer on the Horizons and
Sundowners have a paddle wheel sender. This speedo
sender provides accurate incremental readings (+/- 1.5
MPH) at low speeds as well as high speeds. The speed-
ometer pick-up is located on the transom. See Figure
B5. The paddle wheel extends below the hull.
As the boat is moving, water strikes the wheel making it
spin. The information is relayed to the speedometer
which displays the speed in miles per hour (MPH). The
faster the boat speed, the faster the paddle wheel turns,
and the higher the speed indication on the speedometer.
New for 2000 is that the paddle wheel is capable of de-
termining the water temperature. It is equipped with a
temperature sensor and relays this information to the
module for display.
If the paddle wheel becomes fouled, the speedom-
eter will not register. Clean the paddle wheel.
NOTICE
Speedometers are not precision instruments.
The indications are relative and should never
be used for navigational purposes or similar
critical situations.
DO NOT rely on the speedometer when try-
ing to achieve a “NO WAKE” condition in a
harbor or other enclosed waterway. ALWAYS
reduce throttle! Speedometers are not effec-
tive at measuring low operational speeds. 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.
The temperature indicator on the Horizon and
Sundowner module monitors the coolant temperature.
If the coolant temperature rises to, or above 213 de-
grees F an alarm will sound a single beep every two
seconds and the temperature telltale will illuminate.
NOTICE
Operation of an overheated engine can result
in engine seizure. If an unusually high tem-
perature reading occurs, shut the engine off
immediately.
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 Horizon and
Sundowner dash module.
NOTICE
Operation of an engine with abnormally low
oil pressure can lead to engine damage and
possible seizure. Have the engine serviced
immediately upon a reduced oil pressure indi-
cation.
