Dynamic Ignition Advance Curve
947 Carburator-Equipped Models
The throttle cable features a Hall Effect Switch that
flattens the advance curve until it reaches 80%
throttle.
This feature provides smoother midrange perfor-
mance, while maintaining maximum performance
at wide-open throttle. At 80% throttle and above,
the cable switches ON, and the ignition advances
as much as 12 degrees at certain RPM's.
MULTI-PURPOSE ELECTRONIC
MODULE (MPEM)
The MPEM is directly powered by the battery. It
has a micro-processor inside of its sealed case.
The MPEM is responsible of the following electri-
cal functions:
– interpreting information
– distributing information
– start/stop function
– timer
– Digitally Encoded Security System
– ignition timing curve
– engine rev limiter.
Some fuses are directly mounted onto the MPEM.
All the electrical system is controlled by the MPEM.
It has internal micro-processor and is directly pow-
ered by the battery.
The MPEM features a permanent memory that
will keep the programmed safety lanyard(s) active
and other vehicle information, even when the bat-
tery is removed from the watercraft.
MPEM Functions
Automatic Power Shut-Down
The MPEM is equipped with an automatic power
shut-down. This feature prevents the battery from
loosing its charge if the safety lanyard cap is left
on the switch when the engine is not running.
After connecting the safety lanyard cap, the MPEM
will remain in standby mode during the next 10
minutes, waiting for a starting. If start/stop button
is not depressed, then the MPEM will be automat-
ically powered down.
