● The fuel consumption meter and fuel econ-
omy meter will indicate the same unit of
measurement.
EMU26760
Fuel consumption meter
This gauge displays the total amount of fuel
consumed since the gauge was last reset.
Press the “” (mode) button repeatedly
until the indicator on the face of the gauge
points to total “” (total). To reset the total
fuel consumption to zero, press the “” (set)
and “” (mode) buttons at the same time.
EMU26770
Fuel economy
This gauge displays the distance per liter or
gallon when cruising, and is only for reference
use by the operator.
Press the “” (mode) button repeatedly
until the indicator on the face of the gauge
points to “” (economy).
NOTE:
If twin engines are installed on your boat, the
gauge will only display the total fuel economy
of both engines.
NOTE:
● Fuel consumption varies greatly with boat
design, weight, propeller used, engine trim
angle, sea conditions (including wind), and
throttle position. Fuel consumption also var-
ies slightly with the type of water (salt, fresh,
and contaminate levels), air temperature
and humidity, cleanliness of the boat bot-
tom, engine mounting height, skill of the op-
erator, and individual gasoline formulation
(winter or summer fuel and amount of addi-
tives).
● The Yamaha digital speedometer and fuel
management meter calculates speed,
miles traveled, and fuel economy by water
movement at the stern of the boat. This dis-
tance can vary greatly from the actual dis-
tance traveled because of water currents,
sea swells, and the condition of the water
speed sensor (partially plugged or dam-
aged).
● Individual engines may slightly vary in their
fuel consumption due to manufacturing
variations. These variations can be even
greater if the engines are of different year
models. In addition, variations in propellers,
even of the same basic dimensions of the
same design, can also cause a slight varia-
tion in fuel consumption.
EMU26780
Twin-engine speed synchronizer
This gauge displays the difference in engine
speed (r/min) between the port and starboard
engines for reference purposes when syn-
chronizing the two engines’ speeds.
