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.
Water Temperature
The water temperature gauge indicates the internal water temperature of your engine.
Your engine is equipped with a thermostat to quickly bring the engine up to its optimum
operating temperature range of 150 to 170 degrees f. All outboard engines are also
equipped with a audio alarm system indicating a over heat condition, if the gauge or
alarm indicates a over heat condition, immediately shut the engine off, lift the drive and
inspect water intakes for obstructions such as aquatic vegetation or mud. After finding the
source of the overheating, restart engine and confirm water flow, if water does not flow
within five seconds shut the engine off.
Volt
The volt meter indicates battery voltage; normal reading is between 12 to 15.5 volts. A
low reading indicates too heavy of a load or a dysfunction in the charging system. Too
high of a voltage indicates a fault of the charging circuitry and continued operation will
damage the battery.
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 tach.
readings (for a given throttle setting) indicates loss of power, or an prop entangled with
weeds or trash; check the prop first. A reading higher than normal indicates a ventilating
or cavitating prop, or prop/ drive damage.
Speedometer
The speedometer indicates the speed of your boat in Miles per hour (MPH).
The gauge operates by sensing water impact pressure from the pitot tube mounted on the
transom. (or integrated into the lower drive unit of the motor). If the gauge fails to give a
reading, suspect a blocked pickup.
Trim
The trim gauge indicates the in (down) and out (up) position of the drive unit in relation
to the hull. (see Trimming your boat p.18 )
Options
Optional instrumentation for your Pro Line includes: fish locator / depth finder, VHF
radio, GPS navigation aids, etc. Refer to the manuals supplied.
