Fuel economy
This gauge displays the approximate dis-
tance per liter or gallon when cruising.
If twin engines are installed on your boat, the
gauge will only display the total fuel economy
of both engines.
●
Fuel consumption varies greatly with boat
design, weight, propeller used, engine trim
angle, sea conditions (including wind), and
throttle position. Fuel consumption also
varies slightly with the type of water (salt,
fresh, and contaminate levels), air temper-
ature and humidity, cleanliness of the boat
bottom, engine mounting height, skill of
the operator, and individual gasoline for-
mulation (winter or summer fuel and
amount of additives).
●
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
distance can vary greatly from the actual
distance traveled because of water cur-
rents, sea swells, and the condition of the
water speed sensor (if partially plugged or
damaged).
●
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 propel-
lers, even of the same basic dimensions of
the same design, can also cause a slight
variation in fuel consumption.

Twin-engine speed synchronizer
This gauge displays the difference in engine
speed (r/min) between the port and star-
board engines for reference purposes when
synchronizing the two engines’ speeds.
