Installation and Operation Manual
NAVMAN
Fuel screen
The FISH450 Tricolor is also a petrol fuel computer.
To use these fuel features, first purchase and install
the optional single or twin engine fuel kit.
If
Fuel
does not appear on the
Main Menu
screen
it must be enabled in the
Setup - Fuel
screen. To
enable all fuel functions, change
Num Engines
to
1 (single engine) or 2 (twin engine) as appropriate.
(see
Setup - Fuel
section 4 - 2)
Setup the tank size and select the fuel unit (
L,
USGAL, IMPGAL
) to be used as outlined in the
Setup - Fuel
section.
3-4 Fuel screen
Used
is the total fuel used in litres or gallons since
it was last cleared. This can be reset to 0 by the
Clear Used
command in the
Setup - Fuel
menu
(see section 4-2).
Remaining
is the amount of fuel remaining in the
fuel tank(s) displayed in litres or gallons.
Flow
(fuel consumption) is shown in litres or
gallons per hour. For twin engine installations, the
fuel flow for each engine is shown separately. This
is useful for checking that both engines are under
the same load.
Economy
is the distance travelled per unit of fuel
used. The FISH450 Tricolor uses boat speed and
fuel consumption for this calculation. The
Economy
units are set by the units selected for speed and
fuel (e.g.
NM/L
,
NM/G
,
MI/L
,
MPG
,
KM/L
,
KM/G
).
Adjust the throttle and trim for the best
Economy
.
The bigger the number the better the economy.
CAUTION: Fuel economy can change drastically
depending on boat loading and sea conditions.
Always carry adequate fuel for the journey plus a
sufficient reserve.
Speed
is the current speed of the boat.
Depth
is the current depth of the bottom.

voltage
(or through-hull speed transducer) and measures
the water temperature at that point. An alarm for a
specific temperature or rate of change of temperature
may be enabled in
Setup - Alarms
section 4-1.
Battery
The battery voltage is displayed numerically.
Monitoring this helps prevent the battery running
flat without warning, particularly when using
electronic devices while the battery is not charging.
The battery voltage may provide an early warning
of battery or alternator failure. The battery voltage
will increase after the motor has started if the
alternator is charging correctly.
Log
One of two distance logs can be displayed: Trip
Log or Total Log. Both logs are stored in NAVMAN's
NVM (non volatile memory) when the unit is
switched off. To change the which log displayed see
section 4-6. The Trip log must be reset manually as
most users will want to start and stop during a trip.
Speed
is the current speed of the boat.
Depth
is the current depth of the bottom.
