HOW TO USE THIS MANUAL
1To help identify parts and clarify procedure steps, there are exploded diagrams at the start of
each removal and disassembly section.
2Numbers are given in the order of the jobs in the exploded diagram.
3Symbols indicate parts to be lubricated or replaced (see “SYMBOLS”).
4A job instruction chart accompanies the exploded diagram, providing the order of jobs, names of
parts, notes in jobs, etc.
5Dimension figures and the number of parts, are provided for fasteners that require a tightening
torque.
Example:
Bolt or screw size : M10 (D) × 25 mm (L)
6Jobs requiring more information (such as special tools and technical data) are described
sequentially.10 × 25 mm

INFO
SAFETY WHILE WORKING
Under normal conditions, the lubricants men-
tioned in this manual should not harm or be
hazardous to your skin. However, you should
follow these precautions to minimize any risk
when working with lubricants.
1. Maintain good standards of personal and
industrial hygiene.
2. Change and wash clothing as soon as
possible if soiled with lubricants.
3. Avoid contact with skin. Do not, for exam-
ple, place a soiled rag in your pocket.
4. Wash hands and any other part of the
body thoroughly with soap and hot water
after contact with a lubricant or lubricant
soiled clothing has been made.
5. To protect your skin, apply a protective
cream to your hands before working on the
watercraft.
6. Keep a supply of clean, lint-free cloths for
wiping up spills, etc.
GOOD WORKING PRACTICES
1.The right tools
Use the recommended special service
tools to protect parts from damage. Use
the right tool in the right manner—do not
improvise.
2.Tightening torques
Follow the tightening torque specifications
provided throughout the manual. When
tightening nuts, bolts, and screws, tighten
the large sizes first, and tighten fasteners
starting in the center and moving outward.
