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)
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.
The temperature gauge (included in the 4-in-1 gauge)
monitors the cooling system of the engine. A sudden
increase in water temperature could be a signal of a
blocked cooling passage or a water pump malfunc-
tion.
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 (4-in-1 Gauge)
The oil pressure gauge (included in the 4-in-1 gauge)
indicates the pressure in the engine lubrication sys-
tem. A significant drop in oil pres sure is a possible
indication of an oil pump or other leakage problem.
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.
The engine has been equipped with an audible engine
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.
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.
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.
NOTICE
Speedometers are not precision instruments.
The indications are relative and should never
be used for navigational purposes or similar
critical situations.
E. Voltmeter (4-in-1 Gauge)
The voltmeter (included in the 4-in-1 gauge) monitors
battery condition and thus alternator performance.
See Section H for additional information regarding
electrical systems.
