1.2.2 Fueling instructions
Fueling instructions:
Recommended gasoline:
Regular unleaded gasoline,
If it is not available,
then premium gasoline.
If knocking orpinging occurs,usea different brand of gasoline or premiumunleadedfuel. If leaded gasoline
is usually used, engine valvesand related parts should be inspected after every 100 hours of operation.
WARNING:
Do not smoke whenrefueling, and keep awayfromsparks, flames, or other sources of ignition.
Stop enginebefore refueling.
Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat. Do not overfill the fuel tank.
Take care not to spill gasoline, if gasoline spills, wipe it up immediately.
Tighten the filler cap securelyafterrefueling.
If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eye,
get immediate medical attentions.
If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if
gasoline spills on it.
Touch the fuel nozzleto metalcomponentsto prevent electrostatic sparks.
CAUTION:
Use only new clean gasoline which has been stored in clean containers and is not contaminated
with water or foreign matter.

1.2.3 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. The outboard motor is fitted with propellers chosen to perform
well over a range of applications, but there may be uses where a propeller with a different pitch would be
more appropriate. “PARSUN” dealers stock a range of propellers and can advise you and install a propeller
on your outboard that is best suited to your application.
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.

2. Operation
2.1 Installation
Mount the outboard motor on the center line (keel line) of the boat. For boats without a keel or which are
asymmetrical, consult your dealer.
1
1. Center line (keel line)
NOTE:
During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the
static water level on the exhaust housing is low enough to prevent water entry into the power head,
when waterrises due to waves whenthe outboard is notrunning.
WARNING:
Overpowering a boat could cause severe instability. Do not install an outboard motor with more
horsepower than the maximum rating on the capacityplate of the boat. If the boat doesnot have a
capacityplate, consult the boatmanufacturer.
Improper mounting of the outboard motor could result in hazardous conditions. For
permanently mounted models, your dealer or other person experienced in proper rigging should
mount the motor. If you are mounting the motor yourself, you should be trained by an

6
experienced person. For portable models, your dealer or other person experienced in proper
outboard motormounting should showyou howto mount your motor.
The information presented in this section is intended as reference only. Proper mounting
depends in part on experience and the specific boatand motor combination.
2.1.1 Mounting height
The mounting height of the outboard motor greatly affects your boat running efficiency. If the mounting
height is too high, cavitation tends to occur, thus reducing the propulsion. If the mounting height is too low,
the water resistance will increase and thereby reduce engine efficiency. Mount the outboard motor so that
the anti-cavitation plate is between the bottom of the boat and a level 25mm below it.
NOTE:
The optimum mounting height of the outboard motor is affected by the boat and motor combination
and the desired use. Test runs at a different height can help determine the optimum mounting
height. For further information, consult your “PARSUN” dealeror boat manufacturer.

2.1.2 Clamping the outboard motor
1. Tighten the transom clamp screw evenly and securely. Occasionally check the clamp screws for
tightness during operation of the outboard motor because they could become loose due to engine vibration.
WARNING:
Loose clamp screws could allow the outboard motor to fall off or move on the transom. This
could cause loss of control.
Make sure the clamp screws are tightened securely. Occasionally check the screws for tightness
during operation.
2. If the engine restraint cable attachment is equipped
on your engine, an engine restraint cable or chain
should be used. Attach to a secure mounting point on
the boat to avoid the engine being completely lost if it
accidentally falls off the transom.

8
3. Secure the clamp bracket to the transom using the appropriatebolts. For details, consult your PARSUN
dealer.
WARNING:
Av oid using bolts, nuts or washers inappropriate. After tightening, test running the engine and
check theirtightness.
2.2 Breaking in engine
Your new engine requires a period of break-in to allow mating surfacesof moving parts to wear in evenly.
Gasoline and oil mixing:
CAUTION:
Failure to follow the break-in procedure could result in reduced engine life or even severe engine
damage.
1. First 10 minutes:
Run the engine at idle.
2. Next 50 minutes:
Run the engine at 3000 r/min or atapproximately halfthrottle.
3. Next 2 hoursofoperation:
Run the engine at 4000 r/min or at approximately three-quarter throttle.

4. Next 7 hoursofoperation:
Avoid continuous operation atfull throttle for more than five minutes ata time.
5. Operate the engine normally.
2.3 Pre-operation checks
Fuel
Check to be sure you have plentyof fuel for your trip.
Make sure there are no fuelleaks or gasoline fumes.
Check fuelline connections to be sure they are tight.
Be sure the fueltank is positioned on a secure, flat surface, and that the fuel line isnot twisted or flattened,
or likely to contact sharp objects.
Controls
Check throttle,shift and steering for proper operation before starting the engine.
The controlsshould work smoothly, without binding or unusualfree play.
Look for loose or damaged connections.
Check operation of the starter and stop switches when the outboard motor is in the water.
Engine
Check the engine and engine mounting.
Look for loose or damaged fasteners.
Check the propeller for damage.

10
WARNING:
If any item in the pre-operation check is not working properly, have it inspected and repaired before
operating the outboardmotor. Otherwisean accident could occur.
CAUTION:
Do not start the engine out of water. Overheatingand serious engine damage can occur.
2.4 Filling fuel
WARNING
：
Gasoline and its vapors are highly flammable and explosive. Keep away from sparks, cigarettes,
flames,or othersources of ignition.
1. Remove the fuel tank cap.
2. Carefullyfill thefuel tank.
3. Securelyclose the cap after filling the tank. Wipe up anyspilled fuel.

11
2.5 Starting engine
1. Loosen the air vent screw on the fuel tank cap, 2 or 3 turns.
2. Open the fuel cock.
WARNING:
Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard
where it could become entangled, preventing it from functioning.
Avoid accidentally pulling the lanyard during normal operation. Loss of engine
power means the loss of steering control. Also, without engine power, the boat could
slow rapidly. This could cause people andobjects in the boat to be thrown forward.

12
NOTE:
3. Slightly rotate the throttle grip to approximately one-quarter of full throttle.
4. Pull outair choke handle to close position.
Attach the engine stop switch lanyard to secure
place on your clothing, or your arm or leg. Then
install the lock plate on the other end of the
lanyard into the engine stop switch.

13
5. Pull the manual starter handle slowly until you feel resistance. Then give a strong pull straight to crank
and start the engine. Repeat if necessary.
NOTE:
It is not necessaryto use the choke whenstartinga warmengine.
If the choke is left in the closed position while the engine is running, the engine will run poorlyor
stall.
6.After the engine starts,slowly return the manual starter handle to its original position before releasing it.
7. Slowly return the throttle grip to the fullyclosed position.
CAUTION:
When the engine is cold,it needs to be warmedup.
If the engine does not start on the first try, repeatthe procedure.
If the engine fails to start after 4 or 5 tries, open the throttle a small amount than 1/4, and try
again.
