Fuel Gauge
Your digital engine display shows the current fuel level of the boat. To ensure the safest
boating, always follow the rule of thirds.

Use 1/3 of your fuel to get to your destination.

Use 1/3 of your fuel to return

Leave 1/3 of your fuel in reserve.
This system ensures that your boat has enough fuel in reserve to accommodate for
emergencies that would change your initial boat plan, and will keep your boat from
running out of fuel on the water.
It is important to “calibrate” your fuel gauge during your first initial boat trip. Your fuel
tank is not square, and thus a ½ tank gauge reading may only indicate 1/3 of a tank in
reality. By understanding the correct fuel level for gauge readings, you will more
accurately know the amount of fuel in your tank at any time.
THIS GAUGE IS A MEASURE OF RELATIVE FUEL SUPPLY AND IS
NOT A CALIBRATED INSTRUMENT. ALWAYS LEAVE FUEL IN
RESERVE FOR EMERGENCIES.
Voltmeter
This meter displays the voltage for the battery and charging system, and is incorporated
in the Yamaha digital engine display. The voltmeter should read at least 12.1 volts when
the engines are off, and 13.4 volts when the engines are running. An excessively low or
high voltage reading indicates a problem with your boat’s charging system.
Hour Meter
Unlike cars, where maintenance is done based on mileage, your boat’s service schedule
is based on engine hours. The Yamaha digital engine display incorporates an hour
meter to accurately perform maintenance procedures on schedule.
Engine Alarms
The outboard engines are equipped with several audible engine alarms, as well as
safety modes to reduce the risk of engine damage. Refer to the Yamaha outboard
engine manual for more information of these warnings and alarms.
IF AN ENGINE ALARM SOUNDS, SHUT DOWN THE ENGINE UNTIL
THE SOURCE OF THE PROBLEM IS DETERMINED. MAJOR
ENGINE DAMAGE CAN RESULT IF ALARMS ARE LEFT IGNORED.
Compass
Even with modern GPS systems, a compass is an essential tool for navigation. Not only
does a compass help boaters accurately keep and hold a heading, but it can be used
even if your entire electronics system fails, which can help a boater head for land even
when offshore. Your compass is designed to accurately point towards magnetic north,
which is slightly different than true north. Therefore, you may need to adjust your
compass in order to accurately use it with your paper charts. Please refer to your
compass manual for details.
