A. Electronic Instrumentation and Controls –
These components allow the pilot to operate the boat,
monitor EVC information (boat and engine data), and
make operator settings in the EVC system.
B. Helm Station Control Unit (HCU) – This compo-
nent handles communication between the instrumen-
tation and the controls.
C. Power Train Control Unit (PCU) – This compo-
nent handles communication with the ECM. It moni-
tors and controls the gear shifting, throttle and engine
synchronization functions.
D. Shift Actuator – This component operates the shift
control cable to the drive.
E. Power Trim Pump – This component operates the
power trim function.
Stations
The EVC system requires that there is always one main helm station I from which the boat is operated. There
may be up to three secondary stations from which the boat can be operated J. If the boat has more than one
station, please refer to Station Handling.

throttle and controls engine RPM.
G. Engine Control Module (ECM) – This component
controls and monitors the engine.
H. Volvo Penta options (not shown) – The following
components can be connected to the EVC system to
enable monitoring of non-engine data or other func-
tions:
● Fresh water level sensor
● Fuel tank level sensor
● Multisensor (for speed, water temp, and depth)
● Autopilot and NMEA interfaces (allows the inte-
gration of non-Volvo Penta instrumentation
such as chart plotters, GPS, etc.)
