1.2.2 Fueling instructions

Fueling instructions:

Recommended gasoline:

Regular unleaded gasoline, If

it is not available,

then premium gasoline.

If knocking or pinging occ ur s, use a different brand of ga solin e or pr emium unleaded fuel. If eaded
gasoline is usually used, engi ne valves and related parts should be inspected after every 100 hours of
operation.

WARNING:

 Do not smoke when refueling, an d keep away from sparks, flames, or other sources of ignition.

 St op engine before refueling.

 Refuel in a well-ventilated area. Refuel portable f uel tanks off the boat.

 Do not ov e r f ill the fuel t ank.

 Take care not to spill gasoline, if gasoline spills, wipe it up immediately.

 Tight en the filler cap securely after refueling.

 If y ou should swallow some gasoline, inhale a lot of gas ol ine vapor, or get gasoline in your eye,

get immediate medical attentions.

5

 If any gas ol ine spills onto your skin, immediately wash with soap and water . Change clothing i f

gasoline spills on it.

 Touch the fuel nozzle to metal components to prevent electrostatic sparks.

CAUTION:

Use only new clean gasoline which has been stored in clean con tainers and is not contaminated
with water or foreign matter.

Engine oil:

Recommended engine oil: 2-stroke outboard motor oil.

Gasoline and oil mixing:

Break-in period

25:1

Gasoline 1L 12L 14L 24L

Engine oil 0.04L 0.48L 0.56L 0.96L

After break-in

50:1

Gasoline 1L 12L 14L 24L

Engine oil 0.02L 0.24L 0.28L 0.48L

CAUTION:

Be sure to mix gasoline and oi l com pl etely, otherwise the engine may be damaged.

1.2.3 Propeller select ion

The performance of your out board motor will be critically affected by y our choice of propeller, as an
incorrect choice could adversely affect performance. The outboard motor is fitted with propellers chos en to
perform well over a ra nge of app lications, but ther e may be us es where a propeller with a di ffer ent pitch would

6

be more appropriate. “PARSUN” dealers stock a range of propellers and can advise you and install a
propeller on your outboar d t hat is best suit ed t o your application.

For a greater boat load and a low engine speed, a sma ller-p itch pr ope ller is mor e suit able. Conv ersely, a
large-pitch propeller is more s uitab le for a sma ller operating load as it enables the cor rect engin e spe ed 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 t he boat, at r est, with its maxi m um l oad. Check that
the static water l evel on the exhaust housi ng i s l ow enough to prevent water ent r y into the power
head, when water rises due to waves wh e n the out boar d is not run ni ng.

WARNING:

 Overpowering a boat could cause sever e instabi l ity. Do not install an outboard motor with more

horsepower than t he ma xi mum rati ng on th e c apacity plate of the boat. If the boat do es not hav e
a capacity pl at e, consult the boat manufacturer.

8

 Improp e r m ounting of the outboard motor could result in hazardous conditions.

For permanently mounted mo dels, your dealer or other person experienced i n pr oper rigging
should mount t he motor. If you are mounting the motor y our se l f , you should be trai ne d by an
experienced person. For portable models, your dealer or other person experienced in pr oper
outboard motor mounting shoul d show you how to mount your m ot or.

 The inf or m ation presente d i n this section is int ended as reference only. Proper mounting

depends in part on experience and the speci f i c boat and motor combinati on.

2.1.1 Mounting height

The mounting height of the outboard motor greatly affects your boat runn ing efficiency. If the mounting
height is too high, cavitation tends to occur, t hus r educi ng the propulsion. If the mounting height is too low,
the water resistance w ill increase and thereby reduce engine effic iency. Mount the outboard motor so that
the anti-cavitation plate is between the bottom of the boat and a level 25mm below it.

9

～

NOTE:

The optimum mounting height of the outboard motor is affecte d by the boat and motor
combination and the desired us e . T est runs at a different height can help determine the optimum
mounting height . For further information, consult your “PARSUN” dealer or boat manuf actur er.

2.1.2 Clamping the outboard motor

1. Tighten the transom clamp scr ew evenly and securely. Occasionally check the clamp scr ew s f or
tightness during operati on of the outboard motor because they could become loose due to engine
vibration.

CAUTION:

Outboards that use clamp brack et screws alo ne are INSUFFI CIENT to pr operly and safely secure

the outboard to the Transom. Pr ope r i nstallation of the outb oard includes bol t ing the engine to th e
boat through the transom.

WARNING:

 Loose cl amp screws could allow the o ut board motor to fall off or move on t he t r ansom. This

could cause los s of control.

 Make sure the cl amp screws are tightened securely. Occasionally check the screws for t

ightness during operation.

10

2. If the engine restraint cable attachment is equipp ed on your engin e, an engine r estraint cable or chain

should be used. Attach to a secure mounting poi nt on t he b oat to av oid th e e ngine b ein g co mplet ely
lost if it acc id entally falls off the transom.

3. Secure the clamp bracket to the transom using the a ppropriate bolts. For details, consult your

PARSUN dealer.

WARNING:

Avoid using bolts, nuts or washers inappropriate. After ti ght e ni ng, test running the engine and

check their tightness.

2.2 Breaking in engine

Your new engine requires a period o f br ea k-in to a llo w mat ing sur faces o f movi ng p ar t s to w ear in even ly.

4. Next 7 hours of operation:

Avoid continuous operation at full throttle for mor e than five minutes at a time.

5. Operate the engine normally.

2.3 Pre-operation checks

Fuel

 Check to be sure you have plenty of fuel for your trip.
 Make sure th er e ar e no fuel leaks or gasoline fumes.
 Check fue l line connections to be sure they are t ight .
 Be sure the fu el tank is positioned on a secure, flat surface, and that the fuel line is not twisted or

flattened, or likely to contact sharp objects.

12

Controls

 Check throttle, shift and steerin g for proper operation before starting the engine.
 The controls s hould 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.

Engine

 Check the en gi ne and engine mounting.
 Look for loose or damaged fasteners.
 Check the propeller for damage.

WARNING:

If any item in the pre-operation check is not working prop er ly, have it inspected and repaired

before operati ng the outboard motor. Otherwise an accident could occur.

CAUTION:

Do not star t t he en gi ne out of water. Overheating and serious engine damag e can occur.

2.4 Filling fuel

WARNING：

Gasoline and its vapors are highly fl am m abl e and explosive. Keep away from sparks, cigarettes,

flames, or other sources of ignition.

1. Remove the fuel tan k cap.

13

2. Carefully fill the fuel tank.

3. Securely close the cap after filling the tank. Wipe up any spilled fuel.

2.5 Starting engine

3. Place the gear shift lever in neutral.

14

WARNING:

 The engine must be started in neutra l ot herwise damage to the starter can occur.
 Do not attach the lanyard to clot hing that could tear loose. Do not route the lanyard where it

could become entangled, preventin g i t from functioning.

 A v oid acci dent al ly pulli ng the lany ar d durin g nor mal op eratio n. Lo ss of e ngin e po wer mean s th e

loss of steering control. Also, without engine power, the boat could sl ow rapidly. This could
cause people and object s i n the boat to be thro w n forwar

d.

NOTE:

The start-in-gear protection device prev ents the engine
from startin g except when in neutral. Att ach the engine
stop switch lanyard to secure place on your clothing, or
