Selecting a curve
You must make a fuel consumption curve before you can
use it.
> Fuel consumption curve >select the curve
On the fuel display, press
right if necessary to select
Fuel curve and display the fuel consumption curve.
Note
On a multi engine boat, keep the RPM of all engines •
similar while using a curve.
The shape of the curve depends on the type of speed •
sensor you selected when making the curve.
Using a curve
Compare your boat’s performance now, at the current
RPMs, with the boat’s performance when you made the
curve. You can compare your boat’s performance now
with a curve made under ideal conditions or with a curve
made under similar conditions.
Information in a curve
A RPM of the boat now. For a twin engine boat, the
RPM is the average of the two RPMs.
B Red curve: boat speeds at different RPMs recorded
when you made this fuel consumption curve.
C Red marker: the boat speed now. This marker is
below the red curve, showing that the boat speed
now at this RPM is less than when you recorded the
curve.
D Blue curve: fuel consumption at different RPMs
recorded when you made this fuel consumption
curve.
E Blue marker: the fuel consumption now. This marker
is below the blue curve, showing that the fuel
consumption now at this RPM is better than when
you recorded the curve.
F If the blue curve has a dip, then running the boat at
this RPM will give the best speed for the least fuel
consumption.
