Instruments
Your Pro-Line's instrumentation will vary from model to model and engine to engine.
Therefore, the following descriptions are general. Refer to your engine manual for
specifics.
Fuel Gauge
Differences in temperature, humidity, speed, and trim can affect the actual accuracy of
this gauge in service. It is important to verify the fuel flow in gal./hr. for your boat and
make note of your gauge position with respect to time for different RPM settings. No
gauge can give 100% accuracy. If you notice unusually high or low fuel consumption,
investigate further to see if the engine is using more fuel than normal or the gauge has
failed.
Temperature
The temperature gauge indicates the internal temperature of your engine. Your engine is
equipped with a thermostat to quickly bring the engine up to its optimum operating
temperature range. Outboard engines are also equipped with an audio alarm system
indicating an overheat condition. Many times overheating may occur due to a blockage
of the water intakes caused by aquatic vegetation or mud. Check the water intakes for
blockage and see the engine manual for specific details.
Volt
The volt meter indicates battery voltage. A low reading indicates too heavy of a load or a
malfunction in the charging system. Too high of a voltage reading indicates a fault in the
charging circuitry and continued operation will damage the battery. Refer to engine
manual for specifications.
Tachometer
The tachometer indicates the revolutions per minute (RPM) of your engine. Do not
operate the engine beyond the limits stated in your engine manual. Abnormally low
tachometer readings (for a given throttle setting) indicates loss of power, or a prop
entangled with weeds or trash. Check the prop first. A reading higher than normal may
indicate a ventilating or cavitating prop as well as possible prop / drive damage.
Speedometer
The speedometer indicates the speed of your boat in Miles Per Hour (MPH) and
Kilometers Per Hour (Km/H). The gauge operates by sensing water impact pressure from
the pitot tube which is mounted on the transom (or integrated into the lower drive unit of
the motor) depending upon the motor manufacture. Suspect a blocked pickup if the
gauge fails to give a reading.
Trim
The trim gauge indicates the in (down) and out (up) position of the drive unit in relation
to the hull (see Trim / Tilt on p.25).
Options
Optional instrumentation for your Pro-Line includes: fish locator / depth finder, VHF
radio, GPS navigation aids, etc.. Refer to the manuals supplied.
