GENERAL INFORMATION
IDENTIFICATION
The outboard motor serial number is marked on the label. The label can be found on the bracket left
assembly or on the upper part of the bracket swivel. Record your outboard motor serial number in the
spaces provided to assist you in ordering spare parts from your Parsun dealer or for reference in case
your outboard motor is stolen.
1
1. Outboard motor serial number location
Serial number as follows:
SN
MOTOR BATCH SEQUENCE NUMBER
PRODUCTION CODE
PROPELLER SELECTION
The performance of your outboard motor will be critically affected by your choice of propeller, as an
incorrect choice could adversely affect performance.
For a greater boat load and a low engine speed, a smaller-pitch propeller is more suitable. Conversely,
a large-pitch propeller is more suitable for a smaller operating load as it enables the correct engine speed
to be maintained.
When the engine is running at full throttle position, the suitable propeller should be used according to
the engine’s RPM and the fuel capability. So the outboard engine can supply the best performance.
Propeller sizes Material
9 1/4×8
9 1/4×11 Aluminum alloy
EMERGENCY START
If the starting device is not working, the engine can be started by emergency start cable.
WARNING：
zThe start program can only be used in emergency and to return to harbor for repairing.
zWhen you start the engine by emergency start cable, the start-in-gear protection device is not
working. So please ensure the shift rod is in NEUTRAL position.
zPlease ensure nobody standing behind you in case the cable is pulled out to hurt people.
zAfter the engine starts up, don’t fit the start device or top cowling. Put clothing or other
1

items far away. Don’t touch flywheel or other moving parts.
zWhen starting and operating, don’t touch ignition coil, spark plug cap or other electric parts.
The procedure is as follows:
1. Remove the top cowling.
2. Remove the start-in-gear protection device cable.
1. Start-in-gear protection device cable
1
3. Demount three bolts and remove starter.
4. Insert the knot of the cable in the notch of flywheel rotor, and wind the cable around flywheel
several rounds in clockwise direction..
5. Pull the manual starter handle slowly until you feel resistance.
6. Give a strong pull to start the engine. Repeat if necessary.
SAFETY WHILE WORKING
To prevent the danger or accidents when performing maintenance and repair, and improve the work
efficiency, please obey the following safety procedures.
1. FIRE PREVENTION
Gasoline (petrol), lubricant and grease are highly flammable. While working, keep away from heat,
sparks and open flames.
2

2. VENTILATION
Petroleum vapor and engine exhaust gases are violent in toxicity. They are harmful to breathe and
deadly if inhaled in large quantities. When test-running an engine indoors, maintain good
ventilation.
3. SELF-PROTECTION
Protect your eyes with suitable safety glasses or safety goggles, when drilling, grinding or
operating air compressor. Protect hands and feet by wearing protective work clothes, safety
gloves and shoes if necessary.
4. LUBRICANTS AND SEALING FLUIDS
When performing maintenance procedures and repair to Parsun outboards, use only products
provided or recommended by our Company.
Under normal conditions of use, there should be no hazards from the use of the lubricants
mentioned in this manual, but safety is all-important, and by adopting good safety practices, any
risk is minimized.
○
1To protect the skin, the application of a suitable barrier cream to the hands before working is
recommended.
○
2Clothing which has become contaminated with lubricants should be changed as soon as
practicable, and washed before further use.
○
3Avoid skin contact with lubricants.
○
4Hands and any other part of the body which have been in contact with lubricants or
lubricant-contaminated clothing, should be thoroughly washed with hot water and soap as
soon as practicable.
○
5A supply of clean lint-free cloths should be available for wiping run-off lubricants or grease.
5. GOOD WORKING PRACTICES
○
1Follow the tightening torque instruction. When tightening bolts, nuts and screws, tighten
the large sizes first, and tighten inner-positioned fixings before outer-positioned ones.
○
2Use the recommended special tools to protect parts from damage. Use the right tool in the
right manner.
DISASSEMBLYAND ASSEMBLY
When disassembly and assembly, please follow the following principles：
1. Use special tools when disassembling and assembling.
2. Clean dirt before disassembling the parts.
3. Oil the contact surfaces of moving parts before assembly.
4. Install bearing with the manufacturer’s markings on the side exposed to view and liberally oil the
bearing.
3

5. When installing oil seals, apply a light coating of water-resistant grease to the ledge and outside
diameter.
6. After assembly, check if the moving parts operate normally.
ONE-TIME USE PARTS
One-time use parts are gasket, oil seal, O-ring, cotter pin and spring, ring, and etc.. When
re-assembling outboard engine, you must change the one-time use parts.
PRE-DELIVERY CHECK
To ensure the using, please inspect the following before delivery.
1. CHECKING FUEL SYSTEM
Check if the fuel pipe is connected firmly, and if the fuel tank is filled with fuel.
CAUTION:
Do not use pre-mixed fuel for this 4-stoke outboard engine.
2. CHECKING OIL LEVEL
○
1 Check the engine oil level
Remove oil cap, check engine oil level..
3
21
1. Oil cap 2. High position mark 3. Low position mark
Ensure the oil level between the marks of upper and lower. If above upper level, drain engine
oil; if below lower mark, add engine oil up to upper level.
○ 2 Check the gear oil level
Remove the oil level plug. Check if the gear oil overflows at the oil level checking hole. If
so, install the oil level plug and tighten it according to specified torque. Otherwise please add
gear oil.

3. CHECK STEERING SYSTEM
Check if steering is stable.
1
Check if steering friction is adjusted correctly.
Turn clamp handle screw clockwise to increase
resistance.
Turn clamp handle screw counter clockwise to lower
resistance. 1.Clamphandlescrew
4. CHECK SHIFT LEVERAND THROTTLE
Check if the shift lever is operated smoothly.
Check if the throttle grip is turned smoothly from full closed position to full open position.
5. CHECK ENGINE STOP SWITCH ASSY
Check if the engine stops when pushing the engine stop switch assembly or pulling out the stopper
hang rope.
6. CHECK COOLING WATER CHECKING HOLE.
When the engine is running, check if cooling water overflows at the cooling water checking hole.
1. Cooling water checking hole

7. BREAKING-IN RUNNING
○1 Initial 1 hour: operate the engine at 2000 r/min or about a half throttle.
②The second hour: operate the engine at 3000 r/min or about 3/4 throttle.
③The following 8 hours: operate the engine at full throttle continuously. Each operation time
doesn’t exceed 5 minutes.
8. INSPECTION AFTER BREAKING-IN RUNNING
○1 Check if gear oil contains water..
②Check if the fuel line leaks.
③After breaking-in running, operate the engine at idling speed. Use cleaning tool to wash over
the cooling water passage by fresh water.
9. AFTER BREAKING-IN RUNNING, INSPECT IDLING SPEED.
①Preheating engine for 5 minutes.
②Using the tachometer to measure idling speed RPM.
If out of specification, adjust it. Idling speed: 900~1000 r/min.
③Turn the throttle stop screw clockwise or counter clockwise
until the specified idling speed is attained.
④After adjusting idling speed, picking up RPM several times to check the engine’s stability.

SPECIALTOOLS AND DETECTION DEVICE
When performing maintenance and repair, you need to use all kinds of special tools and detection device.
The use of correct tools will improve the work efficiency and avoid of the damage to the people and
outboard engines.
