8GENERAL SAFETY INFORMATION
NOTICE : DANGER/WARNING/CAUTION/Note
Before installing, operating or otherwise handling your outboard motor, be sure
to thoroughly read and understand this Owner's Manual and carefully follow all of
the instructions. Of particular importance is information preceded by the words
"DANGER," "WARNING," "CAUTION," and "Note." Always pay special attention to
such information to ensure safe operation of the outboard motor at all times.
EMERGENCY STOP SWITCH
The Emergency Stop Switch will stall the outboard motor when the stop switch
tether is pulled off. This stop switch tether can be attached to the operator of
the outboard motor to minimize or prevent injuries from the propeller in case the
operator falls overboard.
We highly recommend use of the Emergency Stop Switch tether.
Failure to observe will result in severe personal injury or death, and possibly property damage.
!
DANGER
Note
This instruction provides special information to facilitate the use or maintenance of the
outboard motor or to clarify important points.
Failure to observe could result in personal injury or property damage.
!
CAUTION
!
WARNING
Failure to observe could result in severe personal injury or death, or property damage.
!
WARNING
Accidental activation of the Emergency Stop Switch (such as the tether being pulled out
in heavy seas) could cause passengers to lose their balance and even fall overboard, or it
could result in loss of power in heavy seas, strong currents, or high winds. Loss of control
while mooring is another potential hazard.
To minimize accidental activation of the Emergency Stop Switch, the 500 mm (20 inch.)
stop switch tether is coiled and can extended to a full 1,300 mm (51 inch.).

GENERAL SAFETY INFORMATION
SAFE OPERATION OF BOAT
As the operator/driver of the boat, you are responsible for the safety of those
aboard and those in other boat around yours, and for following local boating
regulations. You should be thoroughly knowledgeable on how to correctly operate
the boat, outboard motor, and accessories. To learn about the correct operation
and maintenance of the outboard motor, please read through this manual carefully.
It is very difficult for a person standing or floating in the water to take evasive action
should he or she see a power boat heading in his /her direction, even at a slow
speed. Therefore, when your boat is in the immediate vicinity of people in the water,
the outboard motor should be shifted to neutral and shut off.
SERVICING, REPLACEMENT PARTS & LUBRICANTS
We recommend that only an authorized service shop perform service or
maintenance on this outboard motor. Be sure to use genuine parts, genuine
lubricants, or recommended lubricants.
MAINTENANCE
As the owner of this outboard motor, you should be acquainted with correct
maintenance procedures. It is the operator's responsibility to perform all safety
checks and to ensure that all lubrication and maintenance instructions are
complied with for safe operation. Please comply with all instructions concerning
lubrication and maintenance. You should take the engine to an authorized dealer
or service shop for periodic inspection at the prescribed intervals.
Correct periodic maintenance and proper care of this outboard motor will reduce
the chance of problems and limit overall operating expenses.
MOUNTING
Outboard motor mounting must be performed by trained service person(s) using
lift or hoist with sufficient capacity.
!
WARNING
SERIOUS INJURY IS LIKELY IF A PERSON IN THE WATER MAKES CONTACT WITH
A MOVING BOAT, GEAR HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY
ATTACHED TO A BOAT OR GEAR HOUSING.

WARNING - CONTENTS MAY BE UNDER PRESSURE!
As part of the fuel vapour retention system your tank will expand under internal
pressures. This is normal.
TO REMOVE CAP FOLLOW THESE STEPS:
STOP
DIRECTIONS FOR USE:
1. Always loosen cap to relieve tank pressure BEFORE connecting or
disconnecting fuel line.
2. Always disconnect fuel line from engine or fuel tank when not in use.
3. Closure caps should be tightened until an audible “click” is heard.
4. Always remove from vessel for refueling.
5. When removing the closure cap ALWAYS FOLLOW INSTRUCTIONS AND
REMOVE CAP SLOWLY TO REDUCE INTERNAL PRESSURE AND AVOID FUEL
SPILLAGE – CONTENTS MAY BE UNDER PRESSURE!
Open VENT SCREW on top of cap FULLY (VENT SCREW should be CLOSED
for TRANSPORTATION and OPEN for OPERATION AND CAP REMOVAL.)
Locate Pressure Relief Tab under cap. Turn cap until
Pressure Relief Tab Lock engages.
Press down on tab, rotate cap 1/4 turn (to relieve pressure before
opening tank) and release tab. STOP. Lock will engage again.

NOTICE – Pursuant to section 213 of the Clean Air Act (42 U.S.C. section 7545) 40 CFR
1060, in addition to the California Air Resources Board Regulation governing Portable
Outboard Marine Tanks, this portable marine tank and cap assembly has been manufac-
tured to meet the January 2011 regulations contained within the applicable regulations
for emission pe rmeation and fuel vapour retention. This system has a 2 year limited
warranty from Date of Sale.
SPECIAL FEATURES OF THIS SYSTEM
The closure cap includes:
• 2 way vent valve which allows air to enter the tank while engine is in
operation, and a pressure relief valve which is designed for fuel vapour
retention when not in use
• Click-to-close audible close indication
• Manual vent screw (on top of cap) which should be CLOSED for
TRANSPORTATION and OPEN for OPERATION AND CAP REMOVAL.
• Pressure Relief Tab under cap

This fuel tank & cap meets EPA/CARB low permeation regulations. Low permeation
fuel tanks remain full sealed (pressurized) to limit the amount of evaporative
emissions. This tank requires that a Fuel Demand Valve (FDV) or a New style fuel
connector (with sealing mechanism). The FDV and New style fuel connector prevents
pressurized fuel from entering the engine and causing a fuel system overflow or
possible fuel spillage.
Only use a primer bulb/hose assembly that has a Fuel Demand Valve installed in the
fuel hose or a sealing mechanism in the fuel connector as shown below.

WARNING
Most boats are rated and certified
in terms of their maximum allowable
horsepower, as shown on the boat’s
certification plate. Do not equip your boat
with an outboard motor that exceeds this
limit. If in doubt, contact your dealer.
Do not operate the outboard motor until it
has been securely mounted on the boat
in accordance with the instructions below.
1. Mounting the outboard motor on boat
Note
A rope is not included in the standard
accessories.

●Before beginning the running test,
check that the boat with maximum
capacity loading floats on the water in
a proper attitude. Check the position
of water surface on the driveshaft
housing. If the water surface is near
the bottom cowling, in high waves,
water may enter the engine cylinders.
●Incorrect outboard motor mounting
height or existence of underwater
object(s), such as hull bottom
design, bottom surface conditions
or underwater accessories, can
cause water spray possibly reaching
the engine through an opening of
the bottom cowling during cruising.
Exposing engine to such conditions
for extended periods can lead to
severe engine damage.

1. Apply sealing agent such as
silicone sealed between the bolts
and transom board holes before
tightening the bolts.
2. Be sure to tighten mounting bolt
nuts to the specified torque. (30
Nm(3.0kgf)13ft·lb)
Note
It is recommended to install upper
mounting bolts with bolt head at
inside surface of transom. Bolts with
threaded end at inside surface of
transom can cause personal injury.
!
WARNING
●Mounting the outboard motor without
following this manual can lead to
unsafe conditions such as poor
maneuverability, lack of control or fire.
●Loose clamp screws and/or mounting
bolts can lead to the release or
displacement of the outboard motor,
possibly resulting in lost of control and/
or serious personal injury. Be sure that
fasteners are tightened to the specified
torque (30 Nm (3.0kgf)13ft·lb). Check
the fasteners for tightness from time to
time.
●Be sure to use outboard mounting
fasteners included in the outboard
motor package or their equivalents
in terms of size, material, quality and
strength.
Tighten fasteners to the specified
torque (30 Nm (3.0kgf)13ft·lb). Test
cruise to check if fasteners are
tightened securely.
●Outboard motor mounting must
be performed by trained service
person(s) using lift or hoist with
sufficient capacity.
