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.

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 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).
