Controls and Indicators
• Temp - Indicates the engine coolant temperature. Refer to
the engine manual for normal operating temperature. After
starting the engine, check your temperature gauge for
abnormally high readings. If the reading is outside the
manufacturer’s operating range, immediately turn OFF the
engine. An abnormally high temperature indicates a cooling
system problem. Consult your Nautique dealer when
experiencing a high engine temperature reading.
• Oil Pressure - Measures the pressure of the engine’s
lubricating oil. Refer to the engine manual for normal
operating pressure. Many serious engine problems are
reflected on oil pressure gauge readings. If the pressure is
lower than the manufacturer’s specification, immediately
turn OFF the engine. Contact your Nautique dealer to
correct the problem before operating the engine.
• Tachometer/Hour Meter - Registers engine speed in
revolutions per minute (RPM). Use the tachometer to keep
the engine within the proper operating range. Consult the
engine manual for the proper RPM operating range of your
engine. The hour meter LCD display registers accumulated
engine operating time. Time will not be logged unless the
ignition switch is on and the engine is running. Use the hour
meter to keep accurate logs for scheduled maintenance.
• Speedometer - Your Nautique is equipped with a precision
speedometer by Faria. This gauge registers forward speed in
miles per hour (optional kilometers per hour). The
speedometer is equipped with an adjustment knob to
calibrate speedometer accuracy. You can also use this gauge
to monitor fuel consumption and propeller performance.
Speedometer Calibration
The speedometer calibration control knob is located on the under
side of the deck beneath the dash pod above the driver’s right knee.
Drive the boat at a known speed using a GPS or measured course
and adjust the knob until the speedometer is reading correctly.
Turning the knob one direction will raise the needle reading while
turning it in the other direction will lower the reading.
