an option to ensure compatibility with other control
systems.
The throttle, especially if mechanical or provided by third
parties is not part of the engine supply. CMD is not responsible
in any way for damage or danger caused by incorrect use or
by a malfunction of the throttle systems.
When installing the throttle lever, always check that it is not
possible to start the engine, or accelerate the engine during
the gear engagement Also check that the throttle always
allows the propulsion unit control, also in dangerous
conditions.
The engine start up with gear engaged, or the ability
to accelerate the engine during the gear
engagement can cause engine or transmission
failure .
The conditions of use described above represent
a danger to the occupants or to swimmers
passing near the propeller.
5.6.1 Mechanical throttle
For boats with mechanical system control prearrangement
(with tie rods), the engine is provided with potentiometer
already installed on it. The position of the potentiometer varies
according to the type of engine.
The potentiometer is equipped with a pivot around which the
throttle lever rotates. A return spring brings the cable on the
zero position. The useful stroke length is about 80mm. On the
lever there are two types of fastener depending on the
application for which the engine is provided:
Sheath
Cable
Appl.Type fixing

Mercruiser®
C5/C36 Fixed

C2/C8 Adjustable
Check with the diagnostic tool (or with the digital
speedometer - LOAD/UNLOAD function) that the
potentiometer makes the full stroke.

5.6.2 Flexball® electronic throttle
For information on the Flexball® electronic throttle installation
and use consult the manufacturer's manual. The configuration
of the throttle also varies depending on engine level and
transmission selected.
Once installed the throttle, for the electrical connection see
chapter 6.15 – Electronic throttles electrical connection on
page 39, it is necessary to:
1. Adjust the stroke of the actuator (or actuators for twin
installations) gear engagement. This is carried out by
following the requirement in chapters11 and 12 of the
throttle installation manual . The strokes adjustment must
necessarily be carried out in two times (three for water-jet
propulsion unit installations). The setting is made by
changing only the parameters 0L, 0F, 0H (single engine)
or 0L, 0F, 0H, 1L, 1F, 1H (twin engine) inside the control
unit:
a. DRY: A person on board and one on the ground
are required to check the exact engagement
point of the gear.
b. IN THE WATER: Only one person on board for
the setting, which must be carried out strictly with
the engine running and with calm seas. The
engagement of the gear results in a slight
displacement of the boat in the front and rear
direction due to the rotation of the engine in idle.
c. NEUTRAL GEAR BALANCE IN THE WATER
(WATER-JET):the neutral point corresponds to
the condition in which the water-jet propulsion
unit paddle thrusts are perfectly balanced. For
this reason, this setting must be made with the
engine running and calm sea. Only one person
on board is required to make the setting.
2. A verification of the throttle operation electrical
parameters. During the configuration of parameters in the
control unit of the control system, it may happen to
change other parameters not related to the setting of
specific strokes. The parameters are of two types:
a. Specific of the throttle system (as described in
chapter 14.2 of the installation manual of the
control system). These parameters are related to
the throttle system and must not be modified.
b. Specific of the engine (as described in chapter
14.2.2.1 of the installation manual of the control
system). These parameters are related to the
management of the engine throttle and must not
be modified. Changing these parameters can
lead to serious risks to the safety of persons and
in any case will void the warranty.
