Correct and secure installation is
essential for safe boating and good
perf ormance. Follow the installation
instructions provided in this manual.
Bef ore installation, check to be sure
that the outboard motor does not
exceed the recommended maximum
horsepower for the boat on which it
is to be installed. Ref er to the boat’s
certif ication plate f or recommended
maximum horsepower. If the
certif ication plate inf ormation is not
available, contact the boat dealer or
manufacturer.
For most applications, the outboard
motor should have a horsepower
rating which provides 80% of the
maximum recommended horsepower
for the boat.Type:
S:
L:Motor Transom Height
The antiventilation plate of the
outboard motor should be 0 2.0
inches below the bottom of the boat.
With the boat in the water and loaded,
the antiventilation plate should be
about 3.9 inches below the surface of
the water.
Install the outboard motor on the
center of the boat transom.

SAFETY ROPE CLAMP SCREWS
Attach the stern bracket to the boat
transom by tightening the clamp
screws.
Attach a rope from the boat to the
hole in the stern bracket. This will
help to prevent accidental loss of the
outboard motor.Use the transom angle adjustment rod
(p. ) to adjust the angle of the
outboard motor so the propeller is
perpendicular to the surface of the
water. When the outboard motor is installed
extremely low, the idle port may be
immersed and the engine may
become hard to start or may run
poorly. Check that the idle port is
high enough from the water level
when the engine is stopped with the
boat f ully loaded.
Propeller ventilation will occur if the
outboard motor is installed too high
on the boat transom.
If the transom needs to be modified
to accommodate the outboard motor,
contact the boat manuf acturer and
f ollow their recommendations f or
corrective action. Optimum installation height varies
with boat type and bottom shape.
Contact the boat manufacturer for
any special recommendations that are
unique to a specific model of boat.23

							Improperly maintaining
this outboard motor, or
failing to correct a problem
before operation, can cause
a malfunction in which you
could be seriously hurt or
killed.
Always perform a
preoperation inspection
before each operation, and
correct any problem.

and the use of outboard motors.Always wear a PFD (Personal
Flotation Device) while on the boat.
Attach the emergency stop switch
lanyard securely to your PFD or to
your wrist.
For your saf ety, and to maximize the
service life of your equipment, it is
very important to take a f ew
moments before you operate the

							22 Saf ety Inspection Maintenance Inspection
BEFORE OPERATION
Look around the outboard motor
for signs of oil or gasoline leaks.
If you are using the portable fuel
tank, make sure it is in good
condition and properly secured in
the boat (p. ).
Check that the fuel hose is
undamaged and properly
connected (p. ).
Wipe up any spills bef ore starting
the engine.
Check the stern bracket to be sure
the outboard motor is securely
installed.
Check that all controls are
operating properly.
Replace any damaged parts.
Check that all f asteners are in
place and securely tightened.Check the engine oil level (p. ).
Running the engine with a low oil
level can cause engine damage.
Check to be sure the propeller is
undamaged (p. ).
Make sure the tool kit and
emergency starter rope are
onboard (p. ). Replace any
missing items.
Check the f uel level in the f uel
tank (p. ). Check that the anode is securely
attached to the antiventilation plate
(p. ) and is not excessively
worn. The anode helps to protect
the outboard motor from corrosion. 24

IMPORTANT SAFETY
INFORMATION
BEFORE OPERATION. To saf ely realize the f ull potential of
this outboard motor, you need a
complete understanding of its
operation and a certain amount of
practice with its controls.
Before operating the outboard motor
f or the f irst time, please review the
on page and the
chapter titled
For your safety, avoid starting or
operating the engine in an enclosed
area. Your engine’s exhaust contains
poisonous carbon monoxide gas
which can collect rapidly in an
enclosed area and cause illness or
death.Proper break-in procedure allows the
moving parts to wear in smoothly for
best performance and long service
lif e.
For the first 10 hours, run the
outboard motor at low speed, and
avoid f ull-throttle operation.The transom angle adjusting rod is
used to adjust the angle of the
outboard motor in the normal
operating position (p. ).
To adjust, f irst tilt the outboard
motor so it is not resting on the rod.
Push the rod in and turn the end of
the rod up, so the latch will f all into
line with the rod.
Remove the rod and reinsert it in the
desired position.
Push the rod in and turn the end of
the rod down, so the latch will f all to
the locked position. Then release the
rod. 633

							Gasoline is highly
flammable and explosive.
You can be burned or
seriously injured when
handling fuel.
Wipe up spills
immediately. Handle fuel only
outdoors. Stop the engine and keep
heat, sparks, and flame
away.
24 PORTABLE FUEL TANK FUEL HOSE CONNECTIONS
OPERATION
FUEL HOSE CONNECTOR
(OUTBOARD MOTOR SIDE)FUEL HOSE CONNECTOR (FUEL TANK SIDE)
Place the portable fuel tank in a well-
ventilated location, away f rom direct
sunlight, to reduce the possibility of a
gasoline vapor explosion.
To ensure that the outboard motor
will be able to draw f uel f rom the
tank, place the tank within 6 f eet of
the outboard motor and not more
than 3 f eet below the f uel connector
on the outboard motor.Secure the portable fuel tank in the
boat, so it won’t move around and
become damaged.
Before use, open the fuel tank vent
by turning the vent knob at least 2 or
3 turns counterclockwise.
Connect the fuel hose to the tank and
the outboard motor, as shown. Be
sure both connectors snap securely
into place.
