If the boat has one or two SmartCraft capable
Mercury petrol/gasoline engines, connect the
Explorer 538/538i to the SmartCraft engines with
an optional SmartCraft gateway. The display unit
can display engine data and trim and can control
troll speed.

Note:

Fit a single gateway for single engines and a
dual gateway for dual engines.

SmartCraft engines have fuel flow sensors,
therefore Northstar fuel sensors are not
required as well.

If the fuel tank does not have SmartCraft level
sensors, wire for auto power (see section
15-4).

SmartCraft
gateway

NavBus is Northstar’s system for connecting
instruments together to interchage data and
share transducers. When instruments are
connected by NavBus:

If the units, alarms or calibration are changed
in one instrument, then the values will
automatically change in all other instruments
of the same type.

Each instrument can be assigned to a group
of instruments. If the backlight is changed in
an instrument in group 1, 2, 3 or 4 then the
backlight will automatically change in the
other instruments in the same group.

If the backlight is changed in an instrument
in group 0 then no other instruments are
affected.

If an alarm sounds, mute it by clearing the
alarm on any instrument which can display
that alarm.
