28 – FNM® Series HPE – Installation Manual
Make sure that the parameters are set correctly with the
numerical value shown in the installation manual of the
control system.
Failure or bad configuration of gear engagement
strokes and changing the throttle control parameters
with other values can be critical to the propulsion
system, resulting in malfunction or breakage and
void the engine warranty.

Electronic throttle connection kit
For compatibility with other types of electronic control systems,
there is a universal kit:

Electronic throttle connection kit
For the correct use of the kit, it is necessary to connect the
following pins of the 6 way connector:
PIN
Destination
1
GROUND
3
THROTTLE
The ground node used must correspond to the ground
connected to the engine; choose adequate cable diameter and
lengths to transmit this type of signal. Use rubber plugs from
the kit to close the missing pins and ensure that all
connections are watertight.
The throttle signal is a voltage signal that meets the
requirements of the curve in Figure 31 sotto:
Figure 31 - Curve of the throttle signal expected by the engine
The engine load varies in direct proportion with the voltage
between the pins 1 and 3. The maximum and minimum points
are the following:
∆V
1-3
Destination
≤0,75V
0% load
≥4,5V
100% load
The use of electrical signals that do not meet the
requirements described above can damage the
engine control unit and cause a malfunction of the
whole engine unit, including transmission, and voids
the guarantee.
5.6.4
Transmission control
The transmission control in its clutches gear, or in other
operations, depends on the type of transmission and is not
covered by this manual.
For information on the transmission control, refer to the
transmission manufacturer's manual.

Propeller selection and torque engines
installation drawings
The boat manufacturer and engine installer are responsible to
select an appropriate propeller.
The right selection allows the driver of the boat to obtain the
maximum speed of the boat in correspondence of the highest
crankshaft speed of rotation, with a normal load and with the
throttle in the full throttle position.
The following operating conditions can cause a loss of speed.
If this happens, consider the selection of a propeller with minor
step:
Use mainly in warm and humid seasons.
Use at high altitudes.
-
Use with high loads (e.g.. high number of passengers).
-
Use for boats where high accelerations are required (e.g.
sports).
Select the propeller considering that its use at full
load (throttle to stroke end) for long periods with a
propeller with extremely low ratio can damage the
engine.
An appropriate propeller will allow the engine to reach the
maximum rotational speed when the throttle is fully open.
In case of paired installations (two engines), comply with the
propellers rotation diagram shown in: Figure 32: the direction
of rotation must be for both outboard, looking the boat from the
stern..
