Fuel Consumption Meter / Fuel Economy Meter / Twin Engine Speed Synchronizer - Yamaha F115A Owner's Manual

Fuel flow readings are not accurate when the
engine is operating under about 1300 r/min.
As the fuel pump cycles on and off, the dis-
play indicates either no fuel flow or higher
flow than the actual average use.
Dual engine users: the fuel flow meter can
display the fuel flow of either or both engines.
To change the fuel flow display, press the
" " (set) button repeatedly until the gauge
displays " " (for fuel flow to the starboard en-
gine only), " " (for fuel flow to the port engine
only), or " " (for total fuel flow both en-
gines).

 Fuel consumption varies greatly with boat
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 formula-
tion (winter or summer fuel and amount of
additives).
