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：
Do not smoke when refueling, and keep away from sparks, flames, or other sources of
Ignition.
Stop engine before 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 securely after refueling.
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 nozzle to metal components to prevent electrostatic sparks.

7
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(1.7L).
WARNING：
Do not start the engine when the oil level is low. Serious damage might occur.
Always 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 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. Dealers stock a range of propellers and can advise you and
install a propeller on your out board 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 dealers.
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 hazardous conditions. 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.

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.
(0-1in)
0～25mm
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.

10
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.

11
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.
3. Secure the clamp bracket to the transom using the appropriate bolts. For details, consult your dealer.
WARNING：
Avoid using bolts, nuts or washers inappropriate. After tightening, test running 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.
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.

12
1. for the first hour of operation:
Run the engine at 2000 r/min or at approximately half throttle.
2. for the second hour of operation:
Run the engine at3000 r/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.
2.3 Pre-operation checks
Fuel
·Check to be sure you have plenty of fuel for your trip.
·Make sure there are no fuel leaks or gasoline fumes.
·Check fuel line connections to be sure they are tight.
·Be 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
·Check throttle, shift and steering for proper operation before starting the engine.
·The controls should work smoothly, without binding or unusual free play.
·Look for loose or damaged connections.
·Check operation of the starter and stop switches when the outboard motor is in the water.

13
CAUTION
·Do not start the engine out of water. Overheating and serious engine damage can occur.
·Check the engine and engine mounting.
·Look for loose or damaged fasteners.
·Check the propeller for damage.
Checking the engine oil level
1. Put the outboard motor in an upright position (not tilted).
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. Oil dipstick 2 Upper level mark 3.Lower level mark
CAUTION
Be sure to completely insert the dipstick into the dipstick guide.
