SAFETY INFORMATION
For your safety and the safety of others, pay special attention to these precautions.
Operator Responsibility
-Know how to stop the engine
quickly in case of emergency.
Understand the use of all controls.
Do not exceed the boat manufacturer’s power recommendation, and be
sure that the outboard motor is
properly mounted.
Never permit anyone to operate the
outboard motor without proper
instruction.
Stop the engine immediately if any
one falls overboard.
Do not run the motor while the
boat is near anyone in the water.
Attach the emergency stop switch
lanyard securely to the operator.
Do
not remove the engine cover
while the engine is running.
l
Before operating the outboard
.motor, familiarize yourself with all
laws and regulations relating to
boating and the use of outboard
motors.
l
Do not attempt to modify the outboard motor.
l
Always wear PERSONAL
FLOTATION DEVICE (PFD) when
on board.
l
Do not remove any guards, labels,
shields, covers or safety devices;
they are installed for your safety.
Fire and Burn Hazards
Gasoline is extremely flammable, and
gasoline vapor can explode. Use
extreme care when handling gasoline.
l
Remove the fuel tank from the boat
for refueling.
l
Refuel in a well-ventilated area
with the engine stopped. Keep
flames and sparks away, and do not
smoke in the area.
1. SAFETY
l
Refuel carefully to avoid spilling
fuel. Avoid overfilling the fuel tank
(there should be no fuel in the filler
neck). After refueling, tighten the
filler cap securely. If any fuel is
spilled, make sure the area is dry
before starting the engine.

Power Tkim
Press the power trim/tilt switch on the
remote control lever to adjust the
motor trim angle of 0” to 20” to maintain proper boat trim. The power
trim/tilt switch located on the remote
control lever can be operated while the
boat is under way or while stopped.
By
using the power trim/tilt switch the
operator can change the trim angle of
the motor to achieve maximum boat
acceleration, speed, stability and
maintain optimum fuel consumption.
Power Tilt
Press the power trim/tilt switch on the
remote control lever to adjust the
motor tilt angle of 20” to 60’.
By
using the power trim/tilt switch the
operator can change the tilt angle of
the motor for shallow water operation,
beaching, launching from a trailer, or
mooring.

power tilt switch should only be operated with the boat being stopped and
motor off.

The trim meter has a range of 0’ to 20”
and indicates the trim angle of the outboard motor. Refer to the trim ‘meter
when using the power trim/tilt switch
to achieve proper boat performance.

Manual Relief Valve
If the power trim/tilt switch will not
tilt the outboard motor, the motor can
be manually tilted up or down by
opening the manual relief valve. To
tilt the outboard motor manually, turn
the manual valve under the left stem
bracket no more than 1 or 2 turns
counterclockwise using a screw driver.
After tilting the motor, turn the manual
relief valve clockwise securely.
The manual relief valve must be tightened securely before operating the
motor or the motor could tilt up when
operating in reverse.

When making a turn, if an unequal
amount of effort is required to turn
the steering wheel or tiller handle
right or left, adjust the trim tab so
that an equal amount of effort is
required.
TAB

Distribute the load evenly in the boat
and run the boat in straight course at
full throttle. Slightly turn the steering
wheel or tiller handle for both right
and left turns to determine if an equal
amount of effort is required. If adjustment is necessary loosen the tightening bolt and turn the trim tab right or
left. Make small adjustments at a
time and retest. Incorrect trim tab
adjustment can cause adverse steering.
The trim tab also functions as an anode.

OUT OF REACH OF CHILDREN.
Over-Rev Limiter
This outboard motor is equipped with
an engine over-rev limiter which limits
the maximum engine rpm. This overrev limiter protects the engine from
mechanical damage.
The over-rev limiter may be activated
by putting the propeller in a light load
condition or propeller ventilation.
When the over-rev limiter is activated
the engine rpm will become unstable
or erratic. Should this occur reduce the
throttle opening and wait for the
engine r-pm to stabilize then increase
the throttle opening.
On the power trim/tilt type motors lower
the trim angle on high speed turns to reduce the possibility of propeller ventilation.
