Water Separator-Alert Indicator - Yamaha F115 Manuel De L'utilisateur

Instruments and indicators
 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 (if 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 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 starboard
engines for reference purposes when syn-
chronizing the two engines' speeds.
42
1. Port engine speed is higher
2. Port engine speed is slightly higher
3. Engine speed is synchronized evenly be-
tween port and starboard engines
4. Starboard engine speed is slightly higher
5. Starboard engine speed is higher
If the two engines' speeds are not synchro-
nized while cruising, adjusting trim angle or
throttle can synchronize them.
If large differences in trim angle or throttle are
needed to synchronize the engines, consult
your Yamaha dealer for adjustments to the
throttle cables.

Water separator-alert 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.
This indicator only operates when a water
separator sensor is equipped.
