NOTE:
8 Fuel consumption varies greatly with boat
design, weight, propeller used, engine
trim angle, sea conditions (including
wind), and throttle position. Fuel con-
sumption also varies slightly with the type
of water (salt, fresh, and contaminate lev-
els), air temperature and humidity, cleanli-
ness of the boat bottom, engine mounting
height, skill of the operator, and individual
gasoline formulation (winter or summer
fuel and amount of additives).
8 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).
8 Individual engines may slightly vary in
their fuel consumption due to manufactur-
ing variations. These variations can be
even greater if the engines are of different
year models. In addition, variations in pro-
pellers, even of the same basic dimen-
sions of the same design, can also cause
a slight variation in fuel consumption.
