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.
Operation and
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.

NOTE:
During water testing, check the buoyancy of the boat when 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, or when water rises due to waves, or 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.
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 experienced person. For portable models, your dealer or other person
experienced in proper outboard motor mounting should show you how to mount your
motor.
 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.

Mounting Height
0～25mm
(0-1in)
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.

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.

7
1. 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
Pre-Operation Checks
Controls
 Check throttle, shift and steering for proper operation before starting the outboard.
 The controls should work smoothly, without binding or unusual free play.
 Look for loose or damaged connections.
 Check the operation of the On and Off switch when the outboard motor is in the water.
CAUTION:
 Do not start the outboard out of water. Overheating of the water pump can occur.
 Check the outboard mounting.
 Look for loose or damaged fasteners.
 Check the propeller for damage.

9
Starting the Outboard
(Tiller Model)
1. Check to see that the On-Off-Battery switch is in the Off position.
2. Attach the outboard Tether Lanyard to a secure place on your clothing, or on your arm or leg.
Then install the lock plate on the other end of the lanyard into the outboard stop switch
3. Connect the Blue Power Cable to the outboard.
4. Verify the Forward-Reverse switch is in the proper position.
5. Move the Throttle Grip to the minimum position.
6. Push the On-Off-Battery switch to On.
7. Carefully and slowly move the Throttle Grip in increase the outboard speed.
8. Check for steady flow of water from the cooling water pilot hole.

WARNING:
 Do not start the outboard unless the Throttle Grip is in the minimum position.
 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 and objects in the boat to be thrown forward.
Always attach lanyard to clothing or wrist when operating the outboard.

11
Changing Direction for Tiller Model
1. Place the throttle grip in the fully closed position.
2. Move the Forward-Reverse switch to the desired direction position.
On-Off-Battery Check switch on left side.
Forward (FWD) and Reverse (REV) switch on right side.

12
NOTE:
The outboard motor can turn 360° in its bracket (full-pivot system). The boat can also be
backed up by simply turning the outboard motor around 180° with the steering handle facing
toward you.
CAUTION:
 You can change direction at any time, even with the Throttle Grip in the full speed position.
This can cause a shifting lo loads in the boat, but may be necessary if you are moving
too quickly towards a dock.
WARNING:
 When operating in reverse, go slowly. Do not open the throttle more than half. Otherwise
the boat could become unstable, which could result in loss of control and an accident.
Stopping the Outboard (Tiller Model)
PROCEDURE:
1. Push the On-Off-Battery switch to the off position.
NOTE:
The outboard can also be stopped by pulling the lanyard and removing the lock plate from
the Tether stop switch.
In emergency situations, the main Power Cable connector can also be removed to
disconnect power form the outboard.

13
Throttle Friction Adjuster
The throttle friction adjuster is on the tiller handle, which provides adjustable resistance to
movement of the throttle grip, and can be set according to operator preference.
To increase resistance, turn the adjuster clockwise. To decrease resistance, turn the adjuster
counterclockwise. When constant speed is desired, tighten the adjuster to maintain the desired
throttle setting.
WARNING:
 Do not over-tighten the friction adjuster. If there is too much resistance, it could be difficult
to move throttle lever or grip, which could result in an accident.

14
Starting the Outboard
(Remote Control Model)
9. Check to see that the Battery switch is in the Off position.
10. 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 outboard stop switch
11. Connect the Blue Power Cable to the outboard.
12. Verify the Throttle Lever is in the neutral position.
13. Turn the Key switch to On by rotating clockwise.
14. Depress the Handle switch on the Throttle Lever and rotate the Throttle lever forward (for forward
direction) or Reverse (for the reverse direction).
15. Carefully and slowly move the Throttle lever in increase or decrease the outboard speed.
16. Check for steady flow of water from the cooling water pilot hole.
WARNING:
 Before changing direction, make sure there are no swimmers or obstacles in the water
near you.
 Shifting from forward to reverse or vice versa is possible at any time, but care must be
taken to prevent people and equipment from shifting in the boat.
