GENERAL
717 Engine
The digital Capacitor Discharge Ignition (CDI) sys-
tem includes the following components:
Magneto
It is the primary source of electrical energy. It
transforms magnetic field into electric current.
The flywheel contains 4 permanent magnets and
spins around the generating coil. This electric cur-
rent flows to the ignition coil (GTS model) or the
Multi-Purpose Electronic Module (GS and GTI
models).

Ignition Coil
TYPICAL
GTS Model
The ignition coil performs two functions:
It has an integrated capacitor discharged ignition
(CDI) module, which controls the spark occur-
rence (ignition timing curve).
Every half revolution of the flywheel, a critical
point occurs when the position of the magnets
changes the polarity of the current flowing from
the generating coil.
The CDI module detects the change of polarity
and signals at the right time the primary winding
of the ignition coil.
The secondary winding of the ignition coil steps
up the voltage input to high voltage current for
both spark plugs.
GS and GTI Models
The ignition coil steps up the voltage input from
the Multi-Purpose Electronic Module to high volt-
age current for both spark plugs.
The ignition coil is located in the rear electrical
box, on right side of watercraft.
