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.
EMU26791
Water separator warning indicator
This indicator will blink when water has accu-
mulated in the water separator. In such an
event, stop the engine and drain the water
from the separator.
NOTE:
This indicator only operates when a water
separator sensor is equipped.
