Making a fuel consumption curve requires
running the boat in a straight line through the
engine’s full RPM range for about 15 minutes.
For your first curve, choose a calm day with
light wind and little current; have a typical load
and a freshly cleaned hull. Then you can make
fuel consumption curves for different boat,
weather or sea conditions. Compare these
with your first curve to see how your boat’s
performance changes with conditions.
Making a curve
1 Start running the boat in a straight line.
2 Press
one or more times until the
Setup menu is displayed, then select
Fuel
.
3 Select
Fuel consumption curve
,
then select
New
.
4 Enter the comfortable maximum RPM you
have measured for the engine. Do not use
the maker’s maximum RPM.
5 The TRACKFISH then asks you to set
the minimum RPM. Set the throttle for
minimum RPM; for a twin engine boat set
both engines to about the same minimum
RPM.
Now, do not change the engine speed.
Wait for about 60 seconds for the boat to
stabilise, then press
. Wait while the
TRACKFISH records the data.
6 The TRACKFISH then asks you to set the
throttle to achieve a target RPM. For a twin
engine boat set both engines to about the
target RPM. When the engine RPMs are
correct, the Target RPM box will turn green.
Now, do not change the engine speed.
Wait for about 60 seconds for the boat to
stabilise, ensuring the Target RPM box stays
green. Then press
. Wait while the
TRACKFISH records the data.
7 The TRACKFISH repeats the above step to
record data up to the maximum RPM.
Then the TRACKFISH asks if you want to
save the curve. Select Yes. The TRACKFISH
asks for a name for the curve. Change the
default name if required, then press
.
The new curve is stored.
Note
To interrupt making the curve at any time,

12-3 Fuel consumption curves
A fuel consumption curve is a powerful tool for
assessing your boat performance in different
conditions and for helping you to run at the
most economical speed for the conditions.
12-3-1 Making a fuel consumption curve
Fuel consumption curves require engine RPM,
which requires SmartCraft or diesel sensors to
be installed.
