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.
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 ade-
quate ventilation can be maintained.
Self-protection
Protect your eyes by wearing safety glasses
or safety goggles during all operations involv-
ing drilling and grinding, or when using an air
compressor.
Protect your hands and feet by wearing pro-
tective gloves and safety shoes when neces-
sary.
Parts, lubricants, and sealants
Use only genuine Yamaha parts, lubricants,
and sealants or those recommended by
Yamaha, when servicing or repairing the out-
board motor.
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 outboard motor.

6. Keep a supply of clean, lint-free cloths for
wiping up spills, etc.
Good working practices
Special service tools
Use the recommended special service 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 tight-
ening nuts, bolts, and screws, tighten the
large sizes first, and tighten fasteners starting
in the center and moving outward.
Non-reusable parts
Always use new gaskets, seals, O-rings, cot-
ter pins, circlips, etc., when installing or
assembling parts.
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 indicat-
ed in the installation procedure. In addi-
tion, be sure to lubricate the bearings lib-
erally.
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 normal-
ly after assembly.

6D45F11-01 03.10.9 20:41 Page 7

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
outside of the propeller boss.
aPropeller diameter (in inches)
bPropeller pitch (in inches)
cPropeller type (propeller mark)
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 pro-
vides 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 hose is securely con-
nected and that the fuel tank is filled with
fuel.
cC
This is a 4-stroke engine. Never use pre-
mixed fuel.
Checking the engine oil level
1. Check the oil level.
NOTE:
9If the engine oil is above the maximum level
mark a, drain sufficient oil until the level is
between aand b.
9If the engine oil is below the minimum level
mark b, add sufficient oil until the level is
between aand b.

Identification/Propeller selection/Predelivery checks
Checking the gear oil
1. Check the gear oil level.
NOTE:
The gear oil level should be at the brim of the
check hole.
Checking the outboard motor
mounting height
1. Check that the anti-cavitation plate is
between the bottom of the boat and a
maximum of 25 mm (1 in) abelow it. 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 over-
heat. If the mounting height is too low,
water resistance will increase and reduce
engine efficiency.

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 differ-
ent heights.
2. Check that the clamp brackets are
secured with the clamp screws.
Checking the steering system
1. Check the steering friction for proper
adjustment.
2. Check that the steering operates smooth-
ly.
3. Check that there is no interference with
wires or hoses when the outboard motors
steered.
Checking the remote control cables
1. Check that the remote control cable prop-
er position.
2. Set the remote control lever to the neu-
tral position and fully close the throttle
lever. Adjust if necessary.
Checking the gearshift and throttle
operation
1. Check that the gearshift operates
smoothly when the shift lever and or
remote control lever is shifted from neu-
tral into forward or reverse.
2. Check that the throttle operates smooth-
ly when the throttle grip is turned from the
fully closed position to the fully open posi-
tion and or remote control lever is shifted
from the fully closed position to the fully
open position a.

1. Start the engine, then check that the gear
shift operates smoothly.
2. Check the engine idle speed after the
engine has been warmed up.

General information
Break-in
During the test run, perform the break-in
operation in the following 4 stages.
1. For the first hour of operation a: Run the
engine at 2000 r/min or at approximately
half throttle.
2. For the second hour of operation b: Run
the engine at 3000 r/min or at approxi-
mately three-quarter throttle.
3. For the next eight hours of operation c:
Avoid continuous operation at full throttle
for more than five minutes at a time.
4. After the first 10 hours: Operate the
engine normally.
åHours
After test run
1. Check for water in the gear oil.
2. Check for fuel leakage in the cowling.
3. After a test run and while the engine is at
idle, flush the cooling water passages
with fresh water using the flushing kit.
