Performance

1.2.2 Fuel 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 valve 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 gasoline vapor, or get gasoline in your eye, get immediate medical attention.
• If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if gasoline spill s 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 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:

• 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 propeller 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. 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.

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.

(0-1in) 0~25mm

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.
3. Secure the clamp bracket to the transom using the appropriate bolts. For details, consult your PARSUNdealer.

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.

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.

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.

• 2. Upper level mark

1. Oil dipstick 3. Lower 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.

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 becomes firm .

3. Place the gear shift lever in neutral.

NOTE:

The start-in-gear protection device prevents the engine from starting except when in neutral. 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.

WARNING:

• The engine must be started in neutral, otherwise damage to the engine can occur.
• Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard

where it could become entangled and 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 and objects in the boat to be thrown forward.

4. Place the throttle grip in the "START" (start) position.

5. Pull out the choke knob fully.

1. choke knob

NOTE:

• It is not necessary to use the choke when starting a warm engine.
• If the choke is left in the home position while the engine is running, the engine will run poorly or stall.

6. 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.

• 7. After the engine starts, slowly return the manual starter handle to its original position before releasing it.
• 8. Slowly return the throttle grip to the fully closed position.

CAUTION:

• When the engine is cold, it needs to be warmed up.
• If the engine does not start on the first try, repeat the procedure. If the engine fails to start after 4 or 5 tries, open the throttle a small amount (between 1/8 and 1/4), and try again.

For F6/8/9.8FW

1. Place the remote control lever in neutral.

NOTE:

The start-in-gear protection device prevents the engine from starting except when in neutral.

2. Attach the engine stop switch lanyard to a 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.

WARNING:

Attach the engine stop switch lanyard to a secure place on your clothing, or your arm or leg.

Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where it could become entangled and 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 and objects in the boat to be thrown forward.

• 3. Turn the main switch to "ON" (on).
• 4. Open the throttle slightly without shifting using the neutral throttle lever or free accelerator. You may need to change the throttle opening slightly depending on engine temperature. After The engine starts, return the throttle to the original position.

NOTE:

• On remote controls equipped with a neutral throttle lever, a good starting point is to lift the lever just until you feel resistance, then lift slightly more.
• The neutral throttle lever or free accelerator can only be used when the remote control lever is in neutral
• 5. Press in and hold the main switch to operate the remote choke system. The remote chock switch automatically returns to its normal position when our release your hand. Therefore keep the switch pressed in.

• 6. Turn the main switch to "START" (start), and hold it for a maximum or 5 seconds.

7. Immediately after the engine starts, release the main switch and allow it to return to "ON"(on).

CAUTION:

• Never turn the main switch to "START" (start) while the engine is running.
• Do not keep the starter motor turning for more than 5 seconds. If the starter motor is turned continuously for more than 5 seconds, the battery will be quickly discharged, thus making it impossible to start the engine. The starter can also be damaged. If the engine will not start after 5 seconds of cranking, return the main switch to "ON"(on), wait 10 seconds, then crank the engine again.

NOTE:

When the engine is cold, it needs to be warmed up.

2.6 Warming up engine

1. After starting the engine, place the gear shift lever in neutral. For approximately the first 3 minutes after starting, warm up the engine by operating at one fifth throttle or less. Otherwise, will shorten engine life.

CAUTION:

• If the choke knob is left pulled out after the engine starts, the engine will stall.
• In the temperatures of -5℃ or less, leave the choke knob pulled out fully for approximately 30 seconds after starting.
• 2. Check for steady flow of water from the cooling water pilot hole.

CAUTION:

• If water is not flowing out of the hole at all times while the engine is running, stop the engine and check whether the cooling water inlet on the lower case or the cooling water pilot hole is blocked.
• If the problem cannot be located and corrected, consult your PARSUN dealer.

2.7 Shifting

WARNING:

Before shifting, make sure there are no swimmers or obstacles in the water near you.

CAUTION:

To shift from forward to reverse or vice versa, first close the throttle so that the engine idles (or runs at low speeds).

2.7.1 Forward

2.12.2 Cruising in salt water

After operating in salt water, wash out the cooling water passages with fresh water to prevent them from becoming clogged with salt deposits.

3. Maintenance

While using the outboard motor, the periodic maintenance is necessary for you to ensure its performance.

WARNING:

Be sure to turn off the engine when you perform maintenance unless otherwise specified. This work should always be done by a qualified mechanic or your authorized Parsun dealer.

CAUTION:

If replacement parts are necessary, use only genuine PARSUN parts or appropriate parts of the same type and quality.

3.1 Greasing

3.2 Cleaning and adjusting spark plug

You should periodically remove and inspect the spark plug because heat and deposits will cause the spark plug to slowly break down and erode. If necessary, you should replace the spark plug with another of the correct type.

Before fitting the spark plug, measure the electrode gap with a wire thickness gauge; adjust the gap to specification if necessary.

When fitting the plug, always clean the gasket surface and use a new gasket. Wipe off any dirt from the threads and screw in the spark plug to the correct torque.

3.3 Checking the fuel system

1. Check the fuel lines for leaks, crack, or malfunction. If a problem is found, contact your PARSUN dealer and have this repaired immediately.

WARNING:

• Check for fuel leakage regularly.
• If any fuel leakage is found, the fuel system must be repaired by a qualified mechanic.

2. Check the fuel filter periodically. If foreign matter is found in the filter, replace it.

CAUTION:

The fuel filter is one piece, disposable spare part.

3.4 Inspecting idling speed

A diagnostic tachometer should be used for this procedure. Results may vary depending on whether testing is conducted with the flushing attachment, in a test tank, or with the outboard motor in the water.

• 1. Start the engine and allow it to warm up fully in neutral until it is running smoothly.
• 2. Verify whether the idle speed is set to specification.

Idle speed:950 ±50Rpm

CAUTION:

Correct idling speed inspection is only possible if the engine is fully warmed up. If not warmed up fully, the idle speed will measure higher than normal. If you have difficulty verifying the idle speed, or the idle speed requires adjustment, consult a PARSUN dealer or other qualified mechanic.

3.5 Changing engine oil

WARNING:

• Avoid draining the engine oil immediately after stopping the engine. The oil is hot and should be handled with care to avoid burns.
• Be sure the outboard motor is securely fastened to the transom or a stable stand.

• 1. Wash the outboard motor body using fresh water.
• 2. Disconnect the fuel line and tighten the air vent screw,
• 3. Remove the engine top cowling and silencer cover.
• 4. Install the outboard motor on the test tank.

5. Fill the tank with fresh water to above the level of the anti-cavitation plate.

CAUTION:

If the fresh water level is below the level of the anti-cavitation plate, or if the water supply is insufficient, engine seizure may occur.

6. Start the engine. Flush the cooling system. Perform the flushing and fogging at the same time, as fogging/lubricating of the engine is mandatory to prevent engine rust.

WARNING:

• Do not touch or remove electric parts when starting or during the operation.
• Keep hands, hair, and clothes away from the flywheel and other rotating parts while the engine is running.
• 7. Run the engine at a fast idle for a few minutes in neutral position.
• 8. Just prior to turning off the engine, quickly spray "Fogging Oil" alternately into each carburetor or the fogging hole of the silencer cover, if equipped.
• 9. If "Fogging Oil" is not available, run the engine at a fast idle until the fuel system empties and the engine stops.
• 10. If "Fogging Oil" is not available, remove the spark plug(s). Pour a teaspoonful of clean engine oil into each cylinder. Crank several times manually. Replace the spark plug(s).

11. Drain the fuel from the fuel tank completely.

CAUTION:

Store the fuel tank in a dry, well-ventilated place, not in direct sunlight.

5 Actions in emergency

5.1 Impact damage

If the outboard motor hits an object in the water, follow the procedure below.

• 1. Stop the engine immediately.
• 2. Inspect the control system and all components for damage.
• 3. Whether damage is found or not, return to the nearest harbor slowly and carefully.
• 4. Have a PARSUN dealer inspect the outboard motor before operating it again.

5.2 Starter will not operate

If the starter mechanism does not operate, the engine can be started with an emergency starter rope.

WARNING:

• Use this procedure only in an emergency and only to return to port for repairs.
• When the emergency starter rope is used to start the engine, the start-in-gear protection device does not operate. Make sure the remote control lever is in neutral.
• Be sure no one is standing behind you when pulling the starter rope. It could whip behind you and injure someone.
• Do not install the starter mechanism or top cowling after engine is running. Keep loose clothing and other objects away when starting the engine. Do not touch the flywheel or other moving parts when the engine is running.
• Do not touch the ignition coil, spark plug wire, spark plug cap, or other electric components when starting or operating the motor.

Procedure is as follows:

1. Remove the top cowling.
2. Remove the start-in-gear protection cable.

• 1. Start-in-gear protection cable
• 3. Remove the starter after removing the three bolts.

• 4. Prepare the engine for starting. For further information, see section 2.5.
• 5. Insert the knotted end of the emergency starter rope into the notch in the flywheel rotor and wind the rope several turns around the flywheel clockwise.

6. Pull the rope slowly until resistance is felt.

7. Give a strong pull straight out to crank and start the engine. Repeat it necessary.

5.3 Treatment of submerged motor

If the outboard is submerged, immediately take it to a PARSUN dealer. Otherwise some corrosion may begin almost immediately.

• 1. Thoroughly wash away contaminants with fresh water.
• 2. Remove the spark plug(s), then face the spark plug hole downward to allow any mud, or contaminants to drain.
• 3. Drain the fuel from the carburetor, fuel filter, and fuel line. Drain the engine oil completely.
• 4. Fill the sump with fresh engine oil.
• 5. Feed engine fogging oil or engine oil through the carburetor(s) and spark plug holes while starting the engine.

6. Take the outboard motor to a PARSUN dealer as soon as possible.

CAUTION:

Do not attempt to run the outboard motor until it has been completely inspected.
