DIRECTIONS FOR USE
BASIC SAFETY MEASURES
To use the outboard motor you must have all requisites
provided by law (physical suitability, insurance, government
duties, registration, and so on). We suggest you become
familiar with your boat equipped with SELVA motor in places,
which are not too crowded.
Taking some medicines, alcoholic drinks or drugs increase
considerably the risk of accidents.
Make sure that you are in a physical condition suitable for
driving. Pay attention to tiredness and sleepiness.
The engine operator should not let his mind wander, or be
distracted or influenced by other people, things or actions,(do
not smoke, eat, read, and so on.) while steering the boat.
Use fuels and oils suitable for the engine, which are listed in
the "greasing chart ".
Check every so often the oil level and the fuel level.
Stop the motor before every kind of maintenance or cleaning
procedures, and in case of complicated maintenance take the
spark-plug cap out.

PAY ATTENTION TO THE PROPELLER
The propeller is certainly the least protected part of your motor.
It is therefore forbidden to get near the propeller when this is in
rotating. You must leave bathers, skiers and other boat users
enough space to move, in order to avoid any contact with the
propeller.
Picture No. 4.
The engine operator must attach the engine stop switch
lanyard to his wrist when the motor is on.
Picture No. 5.
Never sit on the motor.

If the motor has had an accident, you should have it fully
checked, before you use it again. If necessary let the SELVA
MARINE authorized skilled staff have a look at it.
Do not use the motor, if the damage could have compromised
the sailing safety.
Any alteration attempted on your motor or the removal of any
of its basic elements, can compromise its safety and it is
besides against the law, and anyway it means the immediate
loss of your guarantee.
Observe the laws in force.
Pay great attention to the weather conditions. Listen to the
weather forecast and take the warnings to the sailors into
consideration.
Keep your boat and equipment on board in a perfect state of
efficiency.
Keep enough spare parts on board.
Inform somebody of your route, before sailing.
Prevent fires and explosions.
Before operating an outboard motor, you must know the laws
and regulations relating to navigation.

THE USE OF OUTBOARD MOTOR
PRELIMINARY CONTROLS CHART
DETAIL CHECK DESCRIPTION PAGE
Complete supply Check that the motor supply includes all the components, that are in the
detailed list 13
Check the proper installation of your motor ( the center of the transom). 13
Right installation Check the proper mounting height of your motor. 13
Check the tightness of the clamp screws. 13
Fuel Check the conformity of the fuel to the detailed list. 15
Fuel hose connection Check the proper connection of the fuel hose. 15
Check of the equipment on
board
Check that you have on board everything necessary to face a possible
emergency.
Before leaving always check your motor to make sure that it is
in a perfect state of efficiency, check its proper and safe
functionality. Failure to check as shown in the chart could
result in severe injury to people or damage to the boat.
If you ever have a question about the operation of your
outboard motor, or if you should find any kind of anomaly, please
consult a SELVA MARINE dealer. The time which is needed to check
your motor is very modest, but the safety, that you obtain from it is
enormous

c
13
Check of the supply.
When you receive your motor, check that:
- the packing is integral
- the supply corresponds to the detailed list:
1. the entire motor
2. tool-bag
3. use and maintenance manual
4. certificate of guarantee
5. list of our dealers and our after-sales service
6. registration book (only for the Italian market)
7. CE declaration of conformity
- that there is no evident damage. If there is a damage or if
parts are missing, you must inform immediately and in detail
the forwarding- agent, SELVA joint-stock CO. or its area
agents.
Picture No. 30.
Check that the registration book, the certificate of
guarantee and the CE declaration conformity are
duly filled in and signed, and that the data written in
them correspond to the data printed on the engine’s
label.
Outboard motor mounting
A good position of the motor on the transom is
very important to have an appropriate trim angle and therefore
to obtain a good performance from your boat
To have the optimum mounting height of the outboard motor,
you must mount it so that the anti-cavitation plate is between
the bottom of the boat and a level of 2 cm below it and it is
parallel to it.
If the mounting-height is too high, cavitation tends to
occur and consequently there will be a falling-off in
the performance and a probable overheating of the
motor. If the mounting-height is too low, the water-
resistance will increase and thereby reduce engine
efficiency. Picture No. 31.
The motor must be vertical to the water surface and
the bracket mounted on a flat even surface and
should be fully supported by the top edge of the
transom.
If the bracket is not fully supported or, if the transom
height is too low, a hard wood block should be
securely fitted between the bracket and the transom
Picture No. 32.
Fix the engine in the correct position locking the
clamp screws.
Picture No. 33.

c
14
Trim angle adjusting
The trim angle is the inclination angle, that should be given to
the motor in order to obtain an optimal performance from your
boat.
An improper trim angle does not only affect the
performance of your boat, but can also cause loss of
control, which means danger for the people on
board.
While sailing the motor should be perpendicular to
the water surface, but the trim angle can be 3
degrees to 5 degrees.
If the trim angle is made too great, the buoyancy
center of the boat will shift towards the stern. In this
condition, and if the stability moment at the bow is
large, the boat will tend to "porpoise". If the trim
angle is insufficient, the bow may "plough", making
the boat unstable.
When the boat is in stable trim it remains parallel to
the water.
To adjust the trim angle proceed as follows:
− close the safety valve of the fuel tank;
− tilt up the motor;
− bloc the engine in the tilt position turning downwards the
engine tilt cam;
− remove the adjusting-rod and reposition the rod in the
desired hole, which allows the appropriate trim angle;
− lift the engine, unlock the tilt support bar and bring again
the motor in the vertical position, so that it leans on the
adjustment pin;
Improperly distributed load on boat or in different
positions, can alter the ideal trim conditions.
You must adjust the trim angle when the engine is
switched off.
Picture No. 34
Ensure the transom clamp screws are tightened
securely

c

FUEL
Fuel
The fuel used for the propulsion of internal
combustion engines is highly flammable and, in
certain cases can become explosive.
Refueling and maintenance operations must be done
in a well-ventilated area and with the engine stopped.
Do not smoke while refueling, keep away from
sparks, flames, or other sources of ignition, which
could cause fire or explosion.
Do not spill gasoline. If gasoline spills, wipe it
immediately with dry rags, before starting the motor .
Do not overfill the fuel tank, because gasoline
expands with the heat and the sun radiation.
Tighten the filler cap securely after refueling.
Do not let gasoline get into your eyes or onto your
skin. Avoid swallowing gasoline or inhaling its vapor.
Do not pour fuel off using a pipe.
KEEP OUT OF THE REACH OF CHILDREN
Preparation of the fuel
Use only petrol with an octane number higher than 95
N.O. Research and that does not contain alcohol, with the
addition of 2% of oil proper for mixture (see the detailed list)
For the motors with incorporated fuel tank it is preferable to
use already prepared mixture or you should remove the top
cowling and mix the fuel thoroughly by shaking. In this case at
the end of this operation, you must check the proper
connection of the fast fuel joint, before replacing the cowling.
Picture No. 35
It is a good practice, if you use the motor after a break
longer than one day, to shake the fuel tank in order to mix oil
and petrol thoroughly.
Fuel pipe connection
To connect the fuel pipe to the incorporated fuel tank you need
to link the connection of the pipe to the connection on the fuel
tank placed inside the top cowling. Picture No. 36.
At this point check the connection by pulling the connection
(don’t pull the pipe). Picture No. 37.
To disconnect pull back the knurled outer ring of the fuel
connector which releases the pipe.
The pipe’s connection must be made when the
engine is OFF. Never remove the top cowling when the
engine’s running.

c
16
STARTING
Verifications when the engine is OFF
check that the top cowling is locked.
Picture No. 38.
Make sure that the lock plate is installed on the
engine stop switch. Picture No. 39.
Starting procedures
Loose the safety valve on the fuel tank
If your engine is cold, you have to pull the choke knob.
Picture No. 40.
Place the throttle-grip in the "start" position. Picture No. 41.
Pull the starter-handle slowly so that the starter pinion engages
with the flywheel.
Then give a strong pull, but not too strong, and repeat if
necessary the procedure. Picture No. 42.
Set the choke knob to home position. Picture No. 43.
Pull the starter-handle powerfully until the engine starts.
Picture No. 44.
You don't need to use the choke-knob, if the engine is
warm.
If the motor doesn't start after several attempts, you
should refer to the troubleshooting section.
Verifications when the motor is on
Just after starting the motor, you should make sure that :
- after 5/10 seconds, water runs out from the cooling-
water pilot-holes. The indicator at the entrance of
the circuit, provides only for the proper operation of
the pump and not for the circulation of water in the
head and in the cylinder.
If water does not flow from the pilot-holes check to
see if the water-inlets are blocked. Picture No. 45
- that you do not hear any strange noise;
- that the throttle-grip operates in a proper way;
- that the engine stop switch operates properly;
RUNNING-IN PROCEDURE
A SELVA outboard motor is tested completely in our workshop
and it is partially run in a tank. A second test is done by the
concessionaire It is always advisable to complete the running
in procedure in the following way:
.During the first 15 running hours you must use a fuel
with oil at 3%.

c
17
During the first 3 running hours do not accelerate too
much, and during the following navigation hours you
can accelerate properly but only for short periods.
After about 20 hours you have to change entirely the
gearbox-oil (see the greasing sectioning this
manual).
A good running in will allow you to obtain a good
performance from your motor and a longer endurance of it.
STOPPING PROCEDURE
Emergency stopping procedures.
In an emergency you must stop your motor by pulling
the engine stop switch lanyard.
To start the motor again you have to install the lock
plate again on the engine stop switch.
Picture No. 46.
Stopping in normal conditions
Place the gear-shift lever in the neutral position " N " (neutral
gear); accelerate lightly in order to avoid flooding, run the
engine again at idling speed and then push the stop button.
Picture No. 47.
Stopping for a long period of storage.
If you will not be using the motor for several days, you should
stop the engine in the following way:
Run the engine at idling speed, place the gear-shift lever in
the neutral position " N "and keep the choke knob pulled until
the engine stops.

c
18
OPERATING IN REVERSE GEAR
To run in reverse gear you need to turn the engine through
180° compared to the normal position.
When the engine is in reverse position, the motor’s lift is
automatically prevented by a mechanism.
Use the engine in the reverse position only in
manoeuvre operations and at low r.p.m.
Removal of the motor from the boat
Each time that you remove the motor from your boat,
you must let it cool down and then carry out the
following operations :
- close the air vent valve on the fuel tank
- release the clamp screws.
- lift up the motor vertically and keep it in this position till all the
water has run out from the cooling-water passages ( about 1
minute )
- tilt up the steering tiller
- transport the motor using the proper handle.
- lay down the motor only on its back side.
Picture No. 48.

c

CLEANING
Cleaning outside
SELVA motors do not need much cleaning, to clean the
painted parts use a cloth soaked with water
Do not use flammable solvents.
Cleaning cooling-water passages
Every now and then after using, clean the cooling-water
passages, in order to remove mud and salt, so that they do not
affect the performance of your motor.
You can carry out this cleaning operation in the following way:
Immerse the outboard motor without the propeller in a vessel
filled up with fresh-water, make sure that the water level is over
the height of the water inlets, so that no irreparable damage
could be caused to the motor. Shift the gear-shift lever into
neutral " N ". Start the engine and run at low speed for a few
minutes.
when you start the engine, the propeller shaft turns.
Operate carefully to avoid wounding. Never
approach the hands or other objects to the propeller
shaft.
While cleaning the cooling water passages make sure
that water always circulates in the passages,
checking its running out of the pilot hole.
Picture No. 49.
MAINTENANCE
Before doing any kind of maintenance or check operation,
switch off the engine and wait till it has cooled down, then
remove the spark plug cap, in order to avoid an accidental
staring.
Pay attention to the motor parts, which are still hot, so that you
do not burn yourself.
Some maintenance operations must be carried out by qualified
staff.
Contact SELVA MARINE after-sale service.
The following chart lists the periodic maintenance operations to
do on your motor.
The pointed out operations must be done by qualified
staff.
