Identification numbers record
Outboard motor serial number
The outboard motor serial number is
stamped on the label attached to the port
side of the clamp bracket or the upper part of
the swivel bracket.
Record your outboard motor serial number in
the spaces provided to assist you in ordering
spare parts from your Powertec dealer or for
reference in case your outboard motor is stolen.

Safety information
Before mounting or operating the outboard
motor, read this entire manual. Reading it
should give you an understanding of the
motor and its operation.
Before operating the boat, read any owner’s or operator’s manuals supplied with it
and all labels. Be sure you understand
each item before operating.
Do not overpower the boat with this outboard motor. Overpowering the boat could
result in loss of control. The rated power of
the outboard should be equal to or less
than the rated horsepower capacity of the
boat. If the rated horsepower capacity of
the boat is unknown, consult the dealer or
boat manufacturer.
Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use.
Incorrect propeller selection and incorrect
use may not only cause engine damage,
but also adversely affect fuel consumption.

General information
Consult your dealer for correct use.
Never operate after drinking alcohol or taking drugs. About 50% of all boating fatalities involve intoxication.
Have an approved personal flotation device (PFD) on board for every occupant. It
is a good idea to wear a PFD whenever
boating. At a minimum, children and nonswimmers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating conditions.
Gasoline is highly flammable, and its vapors are flammable and explosive. Handle
and store gasoline carefully. Make sure
there are no gas fumes or leaking fuel before starting the engine.
This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness.
Keep cockpit and cabin areas well ventilated. Avoid blocking exhaust outlets.
Check throttle, shift, and steering for proper operation before starting the engine.
Attach the engine stop switch lanyard to a
secure place on your clothing, or your arm
or leg while operating. If you accidentally
leave the helm, the lanyard will pull from
the switch, stopping the engine.
Know the marine laws and regulations
where you will be boating - and obey them.
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
Tell someone where you are going: leave
a Float Plan with a responsible person. Be
sure to cancel the Float Plan when you return.
Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat handles under the different boating conditions
you may encounter. Operate within your
limits, and the limits of your boat. Always
operate at safe speeds, and keep a careful
watch for obstacles and other traffic.
Always watch carefully for swimmers during the engine operation.
Stay away from swimming areas.
When a swimmer is in the water near you
shift into neutral and shut off the engine.
Do not illegally discard empty containers
used to replace or replenish oil. For the
correct processing of empty containers,
consult the dealer where you purchased
the oil.
When replacing oils used to lubricate the
product (engine or gear oil), be sure to
wipe away any spilt oil. Never pour oil without using a funnel or similar device. If necessary, verify the necessary replacement
procedure with the dealer.
Never illegally discard (dump) the product.
Powertec recommends consulting the dealer on discarding the product.

Take care not to spill gasoline. If gasoline spills, wipe it up immediately with
dry rags.
Do not overfill the fuel tank.
Tighten the filler cap securely after refueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
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 the filler opening or funnel to help 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.
WARNING
This engine is equipped with a neutral
starting device.
The engine will not start unless the shift
control is in neutral position.
Fueling instructions
WARNING
GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE!
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
Gasoline
Recommended gasoline:
Regular unleaded gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
If unleaded gasoline is not available, then
premium gasoline can be used.
Engine oil
Recommended engine oil:
POWERLUBE 2-stroke outboard motor
oil
If the recommended engine oil is not available, another 2-stroke engine oil with an

Battery requirement
CAUTION:
Do not use a battery that does not meet
the specified capacity. If a battery which
does not meet specifications is used, the
electric system could perform poorly or
be overloaded, causing electric system
damage.
For electric start models, choose a battery
which meets the following specifications.

Powertec dealer for details on installing an
optional Rectifier Regulator.
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 and could also seriously
damage the motor. Engine speed depends
on the propeller size and boat load. If engine
speed is too high or too low for good engine
performance, this will have an adverse effect
on the engine.
Powertec outboard motors are 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. For a greater operating
load, a smaller-pitch propeller is more suitable as it enables the correct engine speed
to be maintained. Conversely, a larger-pitch
propeller is more suitable for a smaller operating load.
Powertec dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your application.
CAUTION:
A battery cannot be connected to models
that do not have a rectifier or Rectifier
Regulator.
If you wish to use a battery with the models
without a rectifier or Rectifier Regulator, install an optional Rectifier Regulator.
Using a maintenance-free battery with the
above models can shorten the life of the battery significantly.
Install an optional Rectifier Regulator or use
accessories rated to withstand 18 volts or

NOTE:
Select a propeller which will allow the engine
to reach the middle or upper half of the operating range at full throttle with the maximum
boat load. If operating conditions such as
light boat loads then allow the engine r/min to
rise above the maximum recommended
range, reduce the throttle setting to maintain
the engine in the proper operating range.
For instructions on propeller removal and installation, see page 47.
Start-in-gear protection
Powertec outboard motors or Powertec-approved remote control units are equipped
with start-in-gear protection device(s). This
feature permits the engine to be started only
when it is in neutral. Always select neutral
before starting the engine.

The trim tab should be adjusted so that the
steering control can be turned to either the
right or left by applying the same amount of
force.
WARNING
An improperly adjusted trim tab could
cause difficult steering. Always test run
after the trim tab has been installed or replaced to be sure steering is correct. Be
sure you have tightened the bolt after adjusting the trim tab.
If the boat tends to veer the left (port side),
turn the trim tab rear end to the port side “A”
in the figure.
If the boat tends to veer the right (starboard
side), turn the trim tab end to the starboard
side “B” in the figure.
