Engine & Controls
The helm (dash) features select gauges specifically
designed to monitor the condition of the propulsion
components and other onboard equipment. Close
observation of the gauges is the responsibility of the
captain while cruising. Periodically scan the gauges
for the appropriate meter level deflections. Other
instruments called displays present digital information
verses needle de ection.
Become familiar with all the gauge functions and their
normal operating specifications as outlined in this
manual and your engine operation manual. Gauge
deflection (movement) on boats is very similar to
automobiles.
After educating yourself in the functionality of the
instruments be sure to train another person as the
skipper’s backup. is person should know how to read
the gauges and how to respond to system “fault” codes
should they occur.
Note that the gauges shown in the following pages are typical
and may vary in appearance and type depending on helm
con guration along with engine and components selected.

AUTOMATIC CHARGING RELAY/ SIACR
Note on stern drive dual battery systems there is an au-
tomatic charging relay installed on the battery manage-
ment panel.
e purpose of this device is to protect electronics by
temporarily isolating house loads from the engine cir-
cuit during the engine cranking cycle.
Also, it automatically combines batteries during charg-
ing, isolates batteries when discharging and when in the
engine cranking cycle.
is device supports stern drive alternators up to 120
amps. Remember when charging up a low or dead bat-
tery with the ACR and the dual battery switch, you
must select the COMBINE BATTERIES section of the
dual battery switch for the low battery to recharge.
