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 (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.
EMU26780
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.
Press the “” (mode) button repeatedly
until the indicator on the face of the gauge
points to “” (synchronizer).
NOTE:
If the two engines speeds are not synchro-
nized while cruising, they can be synchro-
nized by adjusting trim angle or throttle.

Command link multifunction meters
Command link multifunction meters have 6
kinds of meter units; tachometer unit (square
or round types), speedometer unit (square
type), speed & fuel meter unit (square or
round types), and fuel management meter
(square type). The indicator system is slight-
ly different between the round and square
types. Check the model and type of your unit
carefully. This manual describes mainly the
warning indicators. For more details on set-
ting meters or changing indicator systems,
see the attached operation manual.
EMU31660
Tachometer unit
The tachometer shows the engine revolu-
tions per minute. It has functions of trim
meter, adjusting trolling speed, cooling wa-
ter/engine temperature display, battery volt-
