Digitally Encoded Security
System (DESS)
This system allows an anti-start pro-
tection against unauthorized use of
the boat. The safety lanyard cap spe-
cifically contains an electronic circuit
that gives it a unique electronic serial
number.
When you buy a new boat, only one
safety lanyard allows starting the en-
gines on your boat. At this point, this
safety lanyard can not be used on an-
other boat and conversely, the one
from another boat can not be used on
your boat unless otherwise pro-
grammed as explained below.
However, the DESS brings a great
flexibility. You can buy additional safe-
ty lanyard(s) and have it (them) pro-
grammed to a boat so that more than
one safety lanyard can be usable on a
particular boat. To have additional
safety lanyard(s) programmed to your
convenience, refer to an authorized
dealer.
2) Steering Wheel
The steering wheel controls the direc-
tion of the jet boat. Turning the steer-
ing wheel clockwise steers the jet
boat to the right and turning it counter-
clockwise steers to the left.
Low-Speed Steering Control
System
Whenever the throttle lever is in
idle
position
and the steering wheel is ap-
proaching the end of its rotation, the
engine speed will be slightly accelerat-
ed to increase the jet pump thrust and
thus improving the steering control for
low speed operation and when ap-
proaching/leaving a dock. Refer to OP-
ERATING INSTRUCTIONS for more
details.
3) Throttle Levers
They control the speed of the engines
and therefore, the speed of the jet
boat. When pushed forward, the jet
boat accelerates. When fully pulled
back, engines return to idle speed and
the jet boat is gradually stopped by
water drag.
NUMBER OF BEEPS
POSSIBLE CAUSE
REMEDY

on DESS post or when
pressing start/stop button in
some cases).

has been programmed for the
boat. If it does not work, refer
