This manual has been prepared by Yamaha primarily for use by Yamaha dealers and their trained
mechanics when performing maintenance procedures and repairs to Yamaha equipment. It has
been written to suit the needs of persons who have a basic understanding of the mechanical and
electrical concepts and procedures inherent in the work, for without such knowledge attempted
repairs or service to the equipment could render it unsafe or unfit for use.
Because Yamaha has a policy of continuously improving its products, models may differ in detail
from the descriptions and illustrations given in this publication. Use only the latest edition of this
manual. Authorized Yamaha dealers are notified periodically of modifications and significant
changes in specifications and procedures, and these are incorporated in successive editions of this
manual.
Important information
Particularly important information is distinguished in this manual by the following notations:
⁄ The Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS
INVOLVED!
Failure to follow WARNING instructions could result in severe injury or death to the machine
operator, a bystander, or a person inspecting or repairing the outboard motor.
A CAUTION indicates special precautions that must be taken to avoid damage to the outboard
motor.
NOTE:
A NOTE provides key information to make procedures easier or clearer.

General information
Safety while working
To prevent an accident or injury and to ensure
quality service, follow the safety procedures
provided below.
Fire prevention
Gasoline is highly flammable.
Keep gasoline and all flammable products
away from heat, sparks, and open flames.
Parts, lubricants, and sealants
Use only genuine Yamaha parts, lubricants,
and sealants or those recommended by
Yamaha, when servicing or repairing the
outboard motor.
Ventilation
Gasoline vapor and exhaust gas are heavier
than air and extremely poisonous. If inhaled
in large quantities they may cause loss of
consciousness and death within a short time.
When test running an engine indoors (e.g., in
a water tank) be sure to do so where adequate
ventilation can be maintained.
Self-protection
Protect your eyes by wearing safety glasses
or safety goggles during all operations involving drilling and grinding, or when using an air
compressor.
Protect your hands and feet by wearing protective gloves and safety shoes when necessary.
Under normal conditions, the lubricants mentioned 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 example, 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
outboard motor.

Safety while working
6.Keep a supply of clean, lint-free cloths for
wiping up spills, etc.
Good working practices
Special tools
Use the recommended special tools to protect
parts from damage. Use the right tool in
the right manner-do not improvise.
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.
Disassembly and assembly
1.Use compressed air to remove dust and
dirt during disassembly.
2.Apply engine oil to the contact surfaces of
moving parts before assembly.
3.Install bearings with the manufacture identification mark in the direction indicated in
the installation procedure. In addition, be
sure to lubricate the bearings liberally.
4.Apply a thin coat of water-resistant grease
to the lip and periphery of an oil seal before installation.
5.Check that moving parts operate normally
after assembly.

Non-reusable parts
Always use new gaskets, seals, O-rings, cotter pins, circlips, etc., when installing or
assembling parts.

Hour meter
A hour meter is incorporated for easier control of interval time for the periodic maintenance.
As the main switch is turned on, all segments light up for 2 seconds to check that the Light Emitting
Diode is not failed.
Then, the meter indicates the total of hours which the engine has been run since manufacture.
The indicated hour is the accumulated time detected by the pulse signal from the lighting coil.
The accumulated hour is held forever, and cannot reset.

Multilayer plating has been given to the piston ring.
The cylinder sleeve without the exhaust slit has been adopted not to accumulate some deposits,
which can prevent the piston rings from entwining.
Also, the shape of the exhaust port has been given the gradual curve design to obtain the best engine
performance and avoid scuffing of the piston ring.

The small end bearing has been given 18 rollers, adding one roller from the previous model, to
increase the durability.
The mating face of the big end bearing has been given a large area to increase the rigidity after
assembling the bearing cap, which increases the rigidty.
Also, a silver plating (30-40µ) has been given to the outside portion of the big end to increase the less

Power unit mount bolt
A fully threaded bolt coated with a sealing material to the thread portion has been adopted for mounting the power unit.
This gives a sealing function to the bolt, which will help prevent the bolt from sticking by the salt water
entering into the thread hole and crystallizing .
Also, the bolt can come out by turning, due to the full thread structure and the sealing material having
a function as an insulator, even if the bolt hole has been choked with corroded particles.
Therefore, an easier servicing such as removing the power unit can be obtained.
NOTE:
Apply a sealing material such as LOCTITE 572 to the bolt thread if the bolt is reused.

Propeller selection
The performance of a boat and outboard motor will be critically affected by the size and type
of propeller you choose. Propellers greatly affect boat speed, acceleration, engine life, fuel
economy, and even boating and steering capabilities. An incorrect choice could adversely
affect performance and could also seriously
damage the engine.
Use the following information as a guide for
selecting a propeller that meets the operating
conditions of the boat and the outboard motor.
Propeller size
The size of the propeller is indicated on the
propeller blade or outside of the propeller boss.
-
Selection
When the engine speed is at the full throttle
operating range (4,500 – 5,500 r/min), the ideal
propeller for the boat is one that provides maximum performance in relation to boat speed and
fuel consumption.

Predelivery checks
To make the delivery process smooth and efficient, the predelivery checks should be completed as explained below.
Checking the fuel system
1. Check that the fuel hoses are securely connected and that the fuel tank is full with fuel.
60H00000
Checking the battery
1. Check the capacity, electrolyte level, and
specified gravity of the battery.
2. Check that the red and black battery cables
are securely connected.
Checking the outboard motor mounting position
1. Check that the anti-cavitation plate is
aligned with the bottom of the boat. If the
mounting height is too high, cavitation will
occur and propulsion will be reduced.
Also, the engine speed will increase abnormally and cause the engine to overheat. If
the mounting height is too low, water resistance will increase and reduce engine efficiency.
1
Use pre-mixed fuel only.
Fuel and oil mixing ratio is 50:1. For breakin period, 25:1 mixture shall be used.
Checking the gear oil
1. Check the gear oil level.
60H30450
S60C1160
NOTE:
The optimum mounting height is affected by
the combination of the boat and the outboard
motor. To determine the optimum mounting
height, test run the outboard motor at different
heights.
2. Check that the clamp brackets are secured
with the mounting bolts.

engine shut-off cord is pulled from the engine shut-off switch.
4. Run the outboard motor for one hour at
3,000 r/min or at half throttle, then for another hour at 4,000 r/min or at 3/4 throttle.
