The hour meter is connected to the ignition switch. Be
sure the ignition switch is in the OFF position when
the engine is not operating or the hour meter will
record additional time.
DO NOT rely on the speedometer when trying
to achieve a “NO WAKE” condition in a harbor
or other enclosed waterway. ALWAYS reduce
throttle! Speedometers are not effective at
measuring low operational speeds. You are
responsible for damage caused by the wake
of your boat.
C. Temperature Gauge (4-in-1 Gauge - Twin)
The temperature gauge (included in the 4-in-1 gauges
on twin engine applications) monitors the cooling sys-
tem of the engine. A sudden increase in water temper-
ature could be a signal of a blocked cooling passage or
a water pump malfunction.
Figure E-5: Tachometer/Hour Meter
B. Speedometer
The speedometer is a water pressure sensitive unit.
It has a pick-up (pitot tube) assembly mounted on the
transom and a small plastic hose (speedo tube) that
connects it to the speedometer gauge on the dash.
See Figure E6. The pitot tube extends below the
hull. Water strikes the tube inlet and creates positive
pressure. The faster the boat speed, the greater the
pressure, and the higher the speed indication on the
speedometer.
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 (4-in-1 Gauge - Twin)
The oil pressure gauge (included in the 4-in-1 gauges
on twin engine applications) indicates the pressure in
the engine lubrication system. A significant drop in oil
pressure is a possible indication of an oil pump or
other leakage problem.
The engine(s) has been equipped with an audible en-
gine alarm, the alarm should sound if the oil pressure
drops below the normal operating range of the engine.
Please see your engine owner’s manual for specific
engine information.
Figure E6: Speedo Sender
If the pick-up becomes clogged, the speedometer will
not register. Clean the opening with a piece of wire or
disconnect the tubing and blow out the pick-up with
compressed air.
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.
When winterizing the boat, the speedometer tubing
must be drained of water. Disconnect the speedome-
ter hose at the pick-up assembly and at the gauge
and blow through the tubing to remove the water.
E. Voltmeter (4-in-1 Gauge - Twin)
NOTICE
The voltmeter (included in the 4-in-1 gauges on twin
engine applications) monitors battery condition and
thus alternator performance. See Section H for addi-
tional information regarding electrical systems.
Speedometers are not precision instruments.
The indications are relative and should never
be used for navigational purposes or similar
critical situations.
