above the graphic 1
.
2. Apply heat to one corner of the graphic.
3. Slowly peel off the heated portion of the
graphic and continue working until you
reach the opposite corner and the entire
graphic is removed.
4. After the graphic is removed, clean the
entire bow area with isopropyl alcohol to
remove any residual adhesive.
Graphic installation
1. Mix 1 tablespoon of liquid detergent and
water in a 1-quart spray bottle.
2. Remove the backing from the new
graphic.
3. Spray the soap and water mixture onto
both sides of the graphic, and also onto
the hull area where the graphic will be
installed.
NOTE:
Spraying the front of the graphic with the soap
and water mixture will protect it from being
scratched during installation.
4. Align the graphic onto the fitting area of
the hull and position it with a squeegee.
NOTE:
Be sure to remove any air bubbles from the
graphic with the squeegee. Work from the top
of the graphic down and slide the squeegee

INTRODUCTION
INTRODUCTION
FEATURES
The newly developed Yamaha Diagnostic System provides quicker detection and analysis of engine
malfunctions for quicker troubleshooting procedures than traditional methods.
By connecting your computer to the ECM (Electronic Control Module) of a watercraft using the com-
munication cable, this software can be used to display sensor data and data stored in the ECM on a
computer’s monitor.
If this software is run on Microsoft Windows
® 95, Windows 98, Windows Me, Windows 2000, or
Windows XP the information can be displayed in colorful graphics. Also, the software can be oper-
ated using either a mouse or a keyboard.
In addition, the data for the main functions (Diagnosis, Diagnosis record, Engine monitor, and Data
logger) can be saved on a disk or printed out.
Functions
1.Diagnosis:
 Each sensor’s status and each ECM diagnosis code or item are displayed. This
enables you to find malfunctioning parts and controls quickly.
2.Diagnosis record:
 Sensors that had been activated and ECM diagnostic codes that have been
recorded are displayed. This allows you to check the watercraft’s record of malfunctions.
3.Engine monitor:
 Each sensor’s status and the ECM data are displayed. This enables you to
find malfunctioning parts quickly.
4.Stationary test:
 With the engine off, ignition, fuel injection, and the electric fuel pump are
checked. These tests can be performed quickly.
5.Active test:
 With the engine running, each firing cylinder drops and the engine speed is
checked for changes to determine if the cylinder is malfunctioning. These tests can be per-
formed quickly.
6.Data logger:
 From the data stored in the ECM, at least two items of 78 seconds of recorded
data are displayed on a graph. In addition, the operating time as compared to the engine speed
and the total operating time are displayed. This allows you to check the operating status of the
engine.
7.ECM No.:
 The ECM part number is displayed.
