Moving the lever forward from the neutral position engages forward gear. Pulling the lever back from
neutral engages reverse. The engine will continue to run at idle until the lever is moved about 35º (a detent
can be felt). Moving the lever farther opens the throttle, and the engine will begin to accelerate.

1.2.2 Fueling instruction
Fueling instructions：
Recommended gasoline:
Regular unleaded gasoline, If it is not
available, then premium gasoline.
If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel. If leaded gasoline is
usually used, engine valves and related parts should be inspected after every 100 hours of operation.
WARNING:
zDo not smoke when refueling, and keep away from sparks, flames, or other sources of
ignition.
zStop engine before refueling.
5

zRefuel in a well-ventilated area; refuel portable fuel tanks off the boat.
zDo not overfill the fuel tank.
zTake care not to spill gasoline, if gasoline spills, wipe it up immediately.
zTighten the filler cap securely after refueling.
zIf you should swallow some gasoline, inhale gasoline vapor, or get gasoline in your eye,
get immediate medical attention.
zIf any gasoline spills onto your skin, immediately wash with soap and water. Change
clothing if gasoline spill s on it.
zTouch the fuel nozzle to metal components to 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.
Engine oil:
Recommended engine oil: 4-stroke outboard motor oil SAE10W30 and SAE10W40 (0.8L).
WARNING:
zDo not start the engine when the oil level is low. Serious damage might occur.
zAlways check the oil level before starting the engine.
CAUTION:
All 4-stroke engines are shipped from the factory without engine oil.
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 propeller chosen
6

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 water rises due to waves when the outboard is not running.
WARNING:
Overpowering a boat could cause severe instability. Do not install an outboard motor with more
horsepower than the maximum rating on the capacity plate of the boat. If the boat does not have a
capacity plate, consult the boat manufacturer.
Improper mounting of the outboard motor could result in dangerous conditions and injury. 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 experienced person.
The information presented in this section is intended as reference only. Proper mounting depends in
part on experience and the specific boat and motor combination.

(0-1in)
0～25mm
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 dealer or 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.
CAUTION:
Outboards that use clamp bracket screws alone are INSUFFICIENT to properly and safely
secure the outboard to the Transom. Proper installation of the outboard includes bolting the
engine to the boat through the transom.
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.
10

3. Secure the clamp bracket to the transom using the appropriate bolts. For details, consult your
PARSUN dealer.
WARNING:
Avoid using bolts, nuts or washers inappropriate. After tightening, test run the engine and
check their tightness.
2.2 Breaking in engine
Your new engine requires a period of breaking to allow mating surfaces of moving parts to wear
in evenly.
CAUTION:
Failure to follow the break-in procedure could result in reduced engine life or even severe engine
damage.
1．For the first hour of operation:
Run the engine at 2000r/min or at approximately half throttle.
2．For the second hour of operation:
Run the engine at 3000r/min or at approximately three-quarter throttle.
3．For the next eight hours of operation:
Avoid continuous operation at full throttle for more than five minutes at a time.
4. Operate the engine normally.
11

2.3 Pre-operation checks
Fuel
zCheck to be sure you have plenty of fuel for your trip.
zMake sure there are no fuel leaks or gasoline fumes.
zCheck fuel line connections to be sure they are tight
zBe sure the fuel tank is positioned on a secure, flat surface, and that the fuel line is not twisted
or flattened, or likely to contact sharp objects.
Controls
zCheck throttle, shift and steering for proper operation before starting the engine.
zThe controls should work smoothly, without binding or unusual free play.
zLook for loose or damaged connections.
zCheck operation of the starter and stop switches when the outboard motor is in the water.
CAUTION:
zDo not start the engine out of water. Overheating and serious engine damage can occur.
zCheck the engine and engine mounting.
zLook for loose or damaged fasteners.
zCheck the propeller for damage.
Checking the engine oil level
1. Put the outboard motor in an upright position (not tilted).
12

2. Check the oil level using the dipstick to be sure the level falls between the upper and lower
marks. Fill with oil if it is below the lower mark, or drain to the specified level if it is above the
upper mark.
1．Oildipstick 3. Lowerlevelmark
2．Upper level mark
CAUTION:
Be sure to completely insert the dipstick into the dipstick guide.
2.4 Filling fuel
WARNING:
Gasoline and its vapors are highly flammable and explosive. Keep away from sparks,
cigarettes, flames, or other sources of ignition.
1. Remove the fuel tank cap.
2. Carefully fill the fuel tank.
13

3. Securely close the cap after filling the tank. Wipe up any spilled fuel.
2.5 Starting engine
1. Connect fuel joints securely after loosing the air vent screw on the fuel tank cap (2 or 3 turns).
2. Connect fuel joints securely and squeeze the primer pump with the outlet end up until you feel it
becomesfirm.
