Speedometer Paddle Wheel - Skier's Choice Supra Sunsport 20V Owner's Manual

Tachometer
The tachometer indicates the engine revolutions per minute
(RPM). Engine Oil Pressure, Engine Coolant Temperature,
and Battery Voltage are also continuously displayed in a Digital
Display located within the Tachometer.
DO NOT exceed the recommended RPM during break-in and
normal operation of your motor. Exceeding the manufacturer's
suggested RPM may cause damage to the engine.
Oil Pressure
The top line of the digital display indicates the pressure of
the lubricating oil inside the engine. Oil Pressure varies with
the engine speed. Oil Pressure typically caries from 6 PSI
at 1,000 RPM up to 80 PSI or greater at cruising speeds.
Low oil pressure may be caused by a low oil level or other
potentially serious problems. If you experience low oil pres-
sure, stop your engine immediately and investigate before
resuming operation.
Running the engine with low oil pressure may cause
severe engine damage.
Coolant Temperature
The second line of the digital display indicates the temperature
of the cooling water inside the engine. The normal operating
temperature will range from 140 degrees F to 190 degrees F.
If you observe excessive engine temperature, stop your engine
immediately and investigate before resuming operation.
NOTICE: Refer to your Engine Owners Manual for
additional details.
Damage from overheating an engine IS NOT
warrantable.

Battery Voltage
The voltage displayed indicates the battery voltage when the
engine is running or the battery voltage when the engine is
stopped. By monitoring the displayed voltage, the driver can
become aware of charging system problems and have them
repaired before starting difficulties occur. The voltmeter should
indicate a voltage between 13.5 and 16 Volts when the engine
is running. The voltage of a fully charged
battery is 12.7 to 12.8 volts when the engine is stopped.
A completely discharged battery will produce 12.0 volts or
less.
Speedometer
The speedometer indicates the water speed of the boat in
miles per hour. It is recommended that the speedometer be
checked for accuracy periodically.
The Depth, Air Temperature, and Lake Temperature are
continuously displayed in a digital display located within the
speedometer.

Speedometer Paddle Wheel

The Speedometer pickup is a paddle wheel located on the
bottom of the boat. Poor water conditions may cause the wheel
to become clogged or give incorrect information.
