EMU26782
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.
ZMU01752
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 var-
ies slightly with the type of water (salt, fresh,
and contaminate levels), air temperature
and humidity, cleanliness of the boat bot-
tom, engine mounting height, skill of the op-
erator, and individual gasoline formulation
(winter or summer fuel and amount of addi-
tives).

calculates
speed,
1.
Port engine speed is higher
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 propellers,
even of the same basic dimensions of the
same design, can also cause a slight varia-
tion in fuel consumption.
2. Port engine speed is slightly higher
3. Engine speed is synchronized evenly be-
tween port and starboard engines

5.
Starboard engine speed is slightly higher
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.
