2008 Four Winns SL Series Boat Owners Manual

Figure E5:  Tachometer/Hour Meter Gauge
C.   Temperature Gauge (4-in-1 Gauge)
B.   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.
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
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 pressure 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
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.
