Outboard Rigging Guide - 2001 Fuel Management Gauge
Digital Fuel Management Gauge
Notes on Fuel Consumption:
1. Fuel consumption will vary greatly with boat
design, weight, propeller used, engine trim
angle, sea conditions (including wind), and
throttle position. Fuel consumption will also
vary slightly with the type of water (salt,
fresh, and contaminate levels), air tempera-
ture and humidity, cleanliness of the boat bot-
tom, engine mounting height, skill of the
operator, and individual gasoline formulation
(winter or summer fuel and amount of addi-
tives).
2. The Yamaha Digital Speedometer and Fuel
Management Meter calculates speed, miles
traveled, and fuel economy by water move-
ment at the stern of the boat. This distance
can vary greatly from the actual distance trav-
eled because of water currents, sea swells,
and the condition of the water speed sensor
(partially plugged or damaged).
3. Individual engines may vary slightly in
their fuel consumption because of manu-
facturing variations. These variations can
be even greater if the engines are of differ-
ent year models. In addition, variations in
propellers, even of the same basic dimen-
sions of the same design, can cause a slight
variation in fuel consumption.
Fuel Management Gauge Operation
Instructions
The Yamaha Fuel Management Gauge System
consists of a fuel flow meter, fuel consumption
meter, fuel economy meter, twin engine speed
synchronizer for dual installations, and an option-
al water separator warning indicator that detects
water in the fuel filter.
Meter Self-Check Function
After the main switch is first turned on, all por-
tions of the meter come on a check. After a few
seconds, the meter will change to normal opera-
tion. Watch the meter when turning on the main
switch to make sure all segments are activated.
