Twin-Engine Speed Synchronizer; Command Link Multifunction Meters - Yamaha LZ300 Owner's Manual

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
G
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
G
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
G
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.
Press the " " (mode) button repeatedly
Basic components
until the indicator on the face of the gauge
points to " " (synchronizer).
1. Port engine speed is higher
2. Port engine speed is slightly higher
3. Engine speed is synchronized evenly
between port and starboard engines
4. Starboard engine speed is slightly higher
5. Starboard engine speed is higher
NOTE:
If the two engines' speeds are not synchro-
nized while cruising, adjusting trim angle or
throttle can synchronize them.

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-
