6.15 Electronic throttles electrical connection

For the electrical connection of the electronic throttle, including
Flexball®, check the following:
1. The ground of the electronic throttle system must match
the ground of the electric engine. The HPE engines are
electronic control engines whose control unit (ECU) reads
the throttle signal as voltage signal referred to the engine
ground.
If the electronic control system does not
correspond to the engine size it can lead to
uncontrolled accelerations and not to the general
operation of the throttle function, causing a
serious hazard for the occupants of the boat.
2. The positive power supply cable of the throttle must never
be directed to the battery or to the positive cable of the
ignition key. It is always necessary to use a relay
connected to the ignition key consent to power the
electronic throttle. Failure to comply with this condition
may cause the following conditions:
With the ignition panel off and the gear lever set
the gear could remain engaged. At the next
power on there is the risk of starting the engine
with gear engaged, creating serious danger to
people's health.
With the ignition panel off the lever remains active,
consuming the engine battery power.
