BOATER’S RESPONSIBILITIES
The operator (driver) is responsible for the correct and safe operation of the boat and
safety of its occupants and general public. It is strongly recommended that each
operator (driver) read and understand this entire manual before operating the outboard.
Be sure at least one additional person on board is instructed in the basics of starting
and operating the outboard and boat handling in case the driver is unable to operate
the boat.

BEFORE OPERATING YOUR OUTBOARD
Read this manual carefully. Learn how to operate your outboard properly. If you
have any questions, contact your dealer.
Safety and operating information that is practiced along with using good common
sense can help prevent personal injury and product damage.
This manual as well as safety labels posted on the outboard use the following
safety alerts to draw your attention to special safety instructions that should be
followed.

1Do not overpower or overload your boat. Most boats will carry a required
capacity plate indicating the maximum acceptable power and load as
determinedby the manufacturer following certain federal guidelines. If in doubt,
contact your dealer or the boat manufacturer.
WARNING
Using an outboard that exceeds the maximum horsepower limit of a boat
can: 1. cause loss of boat control 2. place too much weight at the transom
altering the designed flotation characteristics of the boat or 3. cause the
boat to break apart particularly around the transom area. Overpowering
a boat can result in serious injury, death or boat damage.

LANYARD STOP SWITCH
1The purpose of a lanyard stop switch is to turn off the engine when the operator
moves far enough away from the operator’s position (as in accidental ejection
from the operator’s position) to activate the switch. Tiller handle outboards and
some remote control units are equipped with a lanyard stop switch. A lanyard
stop switch can be installed as an accessory – generally on the dashboard or
side adjacent to the operator’s position.
2The lanyard is a cord usually between 4 and 5 feet (1220 and 1524 mm) in
lengthwhen stretched out with an element on one end made to be inserted into
the switch and a snap on the other end for attaching to the operator. The
lanyard is coiled to make its at-rest condition as short as possible so as to
minimizethe likelihood of lanyard entanglement with nearby objects. It is made
as long as it is in its stretched condition to minimize the likelihood of accidental
activation should the operator choose to move around in an area close to the
normal operator’s position. If it is desired to have a shorter lanyard, wrap the
lanyard around the operator’s wrist or leg, or tie a knot in the lanyard.
Read the following Safety Information before proceeding.
Important Safety Information: The purpose of a lanyard stop switch is to stop
the engine when the operator moves far enough away from the operator’s position
to activate the switch. This would occur if the operator accidentally falls overboard
or moves within the boat a sufficient distance from the operator’s position.
Accidental ejections and falls overboard are more likely to occur in certain types
of boats such as low sided inflatables or bass boats, high-performance boats and
light, sensitive-handling fishing boats operated by hand-tiller. Accidental ejections
and falls overboard are also likely to occur as a result of poor operating practices
such as sitting on the back of the seat or gunwale at planing speeds, standing at
planingspeeds, sitting on elevated fishing boat decks, operating at planing speeds
in shallow or obstacle-infested waters, releasing your grip on a steering wheel or
tiller handle that is pulling in one direction, drinking alcohol or consuming drugs,
or daring, high-speed boat maneuvers.
Whileactivation of the lanyard stop switch will stop the engine immediately, a boat
will continue to coast for some distance depending upon the velocity and degree
of any turn at shut-down. However, the boat will not complete a full circle. While
the boat is coasting, it can cause injury to anyone in the boat’s path as seriously
as the boat would when under power.
We strongly recommend that other occupants be instructed on proper starting and
operating procedures should they be required to operate the engine in an
emergency (e.g. if the operator is accidentally ejected).
WARNING
Should the operator fall out of the boat, the possibility of serious injury
or death from being run over by the boat can be greatly reduced by stop-
ping the engine immediately. Always properly connect both ends of the
stop switch lanyard – to the stop switch and the operator.
Accidental or unintended activation of the switch during normal operation is also
a possibility. This could cause any, or all, of the following potentially hazardous
situations:
1. Occupants could be thrown forward due to unexpected loss of forward motion
– a particular concern for passengers in the front of the boat who could be
ejected over the bow and possibly struck by the gear case or propeller.
2. Loss of power and directional control in heavy seas, strong current or high
winds.
3. Loss of control when docking.
WARNING
Avoid serious injury or death from deceleration forces resulting from ac-
cidental or unintended stop switch activation. The boat operator should
never leave the operator’s station without first disconnecting the stop
switch lanyard from the operator.

PROTECTING PEOPLE IN THE WATER
While You are Cruising
It is very difficult for a person standing or floating in the water to take quick action
to avoid a boat heading in his/her direction even at slow speed.
Always slow down and exercise extreme caution any time you are boating in an
area where there might be people in the water.
Whenever a boat is moving (coasting) and the outboard gear shift is in neutral
position,there is sufficient force by the water on the propeller to cause the propeller
to rotate. This neutral propeller rotation can cause serious injury.
While Boat is Stationary
Shift outboard into neutral and shut off the engine before allowing people to swim
or be in the water near your boat.
WARNING
Stop your engine immediately whenever anyone in the water is near your
boat. Serious injury to the person in the water is likely if contacted by a
rotating propeller, a moving boat, a moving gear case, or any solid device
rigidly attached to a moving boat or gear case.

EXHAUST EMISSIONS
Be Alert To Carbon Monoxide Poisoning
Carbon monoxide is present in the exhaust fumes of all internal combustion
engines including the outboards, stern drives and inboard engines that propel
boats, as well as the generators that power various boat accessories. Carbon
monoxide is a deadly gas that is odorless, colorless and tasteless.
Early symptoms of carbon monoxide poisoning which should not be confused with
seasickness or intoxication, include headache, dizziness, drowsiness, and
nausea.
WARNING
Avoid the combination of a running engine and poor ventilation. Pro-
longed exposure to carbon monoxide in sufficient concentration can
lead to unconsciousness, brain damage, or death.
Good Ventilation
Ventilate passenger area, open side curtains, or forward hatches to remove
fumes.

EXHAUST EMISSIONS (CONTINUED)
Poor Ventilation
Under certain running and/or wind conditions, permanently enclosed or canvas
enclosed cabins or cockpits with insufficient ventilation may draw in carbon
monoxide. Install one or more carbon monoxide detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers and passengers
in an unclosed area of a stationary boat that contains or is near a running engine
may be exposed to a hazardous level of carbon monoxide.
2Examples of Poor Ventilation:
While boat is stationary
a. Running the engine when the boat is moored in a confined space.
b. Mooring close to another boat that has its engine running.
While boat is moving
c. Running the boat with the trim angle of the bow too high.
d. Running the boat with no forward hatches open (station wagon effect).

SELECTING ACCESSORIES FOR YOUR OUTBOARD
Genuine Mercury Precision or Quicksilver Accessories have been specifically
designed and tested for your outboard. These accessories are available from
Mercury Marine dealers.
Some accessories not manufactured or sold by Mercury Marine are not designed
to be safely used with your outboard or outboard operating system. Acquire and
read the installation, operation, and maintenance manuals for all your selected
accessories.
WARNING
Check with your dealer before installation of accessories. The misuse of
acceptable accessories or the use of unacceptable accessories can re-
sult in serious injury, death, or product failure.

SAFE BOATING SUGGESTIONS
In order to safely enjoy the waterways, familiarize yourself with local and other
government boating regulations and restrictions, and consider the following
suggestions.
Use flotation devices. Have an approved personal flotation device of suitable
size for each person aboard (it is the law) and have it readily accessible.
Do not overload your boat. Most boats are rated and certified for maximum load
(weight) capacities (refer to your boat capacity plate). If in doubt, contact your
dealer or the boats manufacturer.
Perform safety checks and required maintenance. Follow a regular schedule
and ensure that all repairs are properly made.
Know and obey all nautical rules and laws of the waterways. Boat operators
should complete a boating safety course. Courses are offered in the U.S.A. by (1)
The U.S. Coast Guard Auxiliary, (2) The Power Squadron, (3) The Red Cross and
(4) your state boating law enforcement agency. Inquiries may be made to the
BoatingHot-line, 1-800-368-5647 or the Boat U.S. Foundation information number
1-800-336-BOAT.
Make sure everyone in the boat is properly seated. Don’t allow anyone to sit
or ride on any part of the boat that was not intended for such use. This includes
backs of seats, gunwales, transom, bow, decks, raised fishing seats, any rotating
fishing seat; anywhere that sudden unexpected acceleration, sudden stopping,
unexpected loss of boat control or sudden boat movement could cause a person
to be thrown overboard or into the boat.
Never be under the influence of alcohol or drugs while boating (it is the law).
They impair your judgment and greatly reduce your ability to react quickly.
Prepare other boat operators. Instruct at least one person on board in the basics
of starting and operating the outboard and boat handling in case the driver
becomes disabled or falls overboard.
Passenger boarding. Stop the engine whenever passengers are boarding,
unloadingor are near the back (stern) of the boat. Just shifting the outboard into
neutral is not sufficient.
Be alert. The operator of the boat is responsible by law to “maintain a proper
lookout by sight (and hearing).” The operator must have an unobstructed view
particularly to the front. No passengers, load, or fishing seats should block the
operators view when operating the boat above idle speed.
Never drive your boat directly behind a water skier in case the skier falls. As
an example, your boat traveling at 25 miles per hour (40 km/hr) in 5 seconds will
overtake a fallen skier who was 200 feet (61m) in front of you.

90-891950R GB
ob GENERAL INFORMATION
SAFE BOATING SUGGESTIONS (CONTINUED)
Watch fallen skiers. When using your boat for water skiing or similar activities,
always keep a fallen or down skier on the operator’s side of the boat while returning
to attend the skier. The operator should always have the down skier in sight and
never back up to the skier or anyone in the water.
Report accidents. Boat operators are required by law to file a Boating Accident
Report with their state boating law enforcement agency when their boat is involved
in certain boating accidents. A boating accident must be reported if (1) there is loss
of life or probable loss of life, (2) there is personal injury requiring medical treatment
beyond first aid, (3) there is damage to boats or other property where the damage
value exceeds $500.00 or (4) there is complete loss of the boat. Seek further
assistance from local law enforcement.

RECOMMENDATIONS FOR THE SAFE USE
OF LPG AS A PROPULSION FUEL FOR
BOATS, YACHTS AND OTHER CRAFT
The information is given in good faith and believe in its accuracy, but does not imply
any acceptance of legal liability or responsibility by Mercury Marine.
TYPICAL PROPERTIES OF LPG
LPG is the commercial name for commercial propane and commercial butane.
There are hydrocarbon products produced by the oil and gas industries.
The combustion of LPG produces carbon dioxide (CO2) and water vapour, but
sufficient air must be available. Inadequate appliance fuelling and / or ventilation,
or poor air gas mixing (for example due to lack of servicing) can result in the
production of toxic carbon monoxide.
Everyone concerned with the storage and handling of LPG should be familiar with
the following characteristics and potential hazards:
1. LPG is stored as a liquid under pressure. It is almost colourless and its weight
is approximately half that of an equivalent volume of water.
2. LPG vapour is denser than air: butane is about twice as heavy as air and
propane about one and a half times as heavy as air. Consequently, the vapour
may flow along the ground and into drains, sinking to the lowest level of the
surroundings and be ignited at a considerable distance from the source of
leakage. In still air vapour will disperse slowly.
3. LPG can form a flammable mixture when mixed with air. The flammable range
at ambient temperature and pressure extends between approximately 2 % of
the vapour in air at its lower limit and approximately 10 % of the vapour in air
at its upper limit. Within this range there is a risk of ignition. Outside this range
any mixture is either too weak or too rich to propagate flame. However,
over–rich mixtures can become hazardous when diluted with air and will also
burn at the interface with air.
At pressures greater than atmospheric, the upper limit of flammability is
increased but this increase with pressure is not linear.
4. Escape of even small quantities of the liquefied gas can give rise to large
volumes of vapour / air mixture and thus cause considerable hazard.
A naked flame should never be used to search for a leak.
5. At very high concentrations in air, LPG vapour is anaesthetic and subsequently
an asphyxiant by diluting or decreasing the available oxygen.
6. Commercial LPG is normally odorised before distribution by the addition of an
odorant, to enable detection by smell of the gas at concentrations down to
one–fifthof the lower limit of flammability (i.e. approximately 0, 4 % of the gas
in air).
7. Escape of LPG may be noticeable other than by smell. When the liquid
evaporates, the cooling effect on the surrounding air causes condensation and
even freezing of water vapour in the air. This effect may show itself as frost at
the point of escape and thus make it easier to detect an escape of LPG.
Because the refractive index of LPG differs from air, leaks can sometimes be
seen as a ’shimmering’.
8. Owing to its rapid vaporisation and consequent lowering of temperature, LPG,
particularly liquid, can cause severe frost burns if brought into contact with the
skin. Personal protective equipment (e.g. hand and eye protection) should be
worn if this hazard is likely to occur.
9. A container which has held LPG and is ’empty’ may still contain LPG in vapour
form and is thus potentially dangerous. In this state the internal pressure is
approximately atmospheric. If a valve is leaking or is left open, air can diffuse
into the container forming a flammable mixture and creating a risk of explosion:
alternatively, LPG can diffuse to the atmosphere.
Note: These properties are general characteristics of LPG, and items such as 8
should not occur in normal cylinder usage.

RECOMMENDATIONS FOR THE SAFE USE
OF LPG AS A PROPULSION FUEL FOR
BOATS, YACHTS AND OTHER CRAFT
DEFINITIONS
Competent person: A person with knowledge, training and ability to carry out
their work safely and with the necessary proficiency to ensure the subsequent
safe operation of the vessel.
Component: Any equipment thought which the LPG or other fuel flows and is
added as part of the vessel conversion.
Cylinder: Any vessel or container of approved design containing LPG under
pressure used to transport or store LPG.
Bi–Fuel: Where two alternative fuels are provided.
LPG locker or compartment: A purpose designed enclosure to hold only the
LPG gas bottle (s) and the associated regulator(s) safety equipment and hose(s).
Stop fill valve: A double check level device, which prevents the over filling of a
fuel container beyond a pre–determined liquid level (usually 80 %)
A lock–off valve: A term used to describe a shutt–off valve in the fuel feed line
which will automatically shutt–off the fuel feed to the engine under specified
conditions relating to vessel operation and safety.
Non Return Valve / Check valve: A device to permit flow in one direction and
prevent the flow in opposite direction.
LPG CYLINDERS AND STORAGE
Liquefied Petroleum Gas (LPG) cylinders should be stowed on the open deck
either completely in the open air or in a deck locker compartment which should be
vented at low level and high level, so that any leakage of gas can disperse rapidly
and be prevented from entering the hull interior.
Lockers or compartments should not be used for the storage of any equipment
than LPG cylinders, and associated control equipment and kept clear of
extraneous materials. Unconnected reserve or empty cylinders should be stowed
similarly to those in service. Cylinder valves should be kept closed when the
engine is not in use and when cylinders are regarded as empty.
IMPORTANT
1. Cylinders should never be stowed below the deepest loaded water line.
2. Cylinders should not be mounted outside the plan view of the hull.
STOWAGE ON THE DECK
The sitting of the stowage area should be such that:
1. The possibility of cylinders sustaining mechanical damage is reduced to the
minimum.
2. Neither the cylinders nor the compartment form an obstruction.
3. The area is at least 1 m away from hatches, other openings or possible sources
of ignition.
4. The cylinders are secured in the correctly orientated position
5. The cylinders are easily accessible and readily removable in an emergency.
STOWAGE WITHIN A VESSEL
Stowage within a vessel means any location within the hull of the vessel including
the cockpit of launches or recesses in decks as well as below decks or within the
superstructure of large vessels.
In all cases LPG cylinders should be stowed in a separate locker or compartment.
LPG cylinders should not be stowed in accommodation spaces.
CONSTRUCTIONS OF CYLINDER LOCKERS AND
COMPARTMENTS
The construction and location of cylinder lockers or compartment should be such
that there is an adequate separation of the cylinder compartment and /or the
compartment sited in a low risk position in the boat, and the following conditions
should be complied with:
1. Cylinders should be secured in the correctly orientated position.
2. A locker or compartment should be vapour–tight to the hull interior and
openableonly from the top except in the case of a deck locker which may be
openable from the outside.
3. The material used in the construction of a locker or compartment should have
a fire resistance of 30 min.
4. The locker or compartment should be ventilated at low and high level outside
the hull or superstructure. The low level ventilation should be from the locker
or compartment bottom above the deepest loaded waterline. Drainage / vent
pipes should be of not less than 13 mm internal diameter for containers having
a combined capacity of up to 15 kg but they should be enlarged pro rata where
additional gas is carried. The opening should be remote from the engine
exhaust system and at least 250 mm from it. The opening should, by position
or other means, be protected from blockage, both from within and without.
5. For compartments situated wholly below deck but above the deepest loaded
waterline, flame arresters should be fitted at the vent outlets unless the
ventilationis to a safe area.
6. The locker or compartment should be designed to hold both the cylinders and
the associated regulator equipment. The supply from the locker or
compartment should be fixed by pipework from suitable bulkhead fitting.
7. The opening into a locker or compartment should allow for the operation of any
valves, replacement of cylinders, and access to connections or regulating
devices. The position of any main gas valve should be clearly indicated.
8. The readily ignitable material should not be placed in compartments used for
housing the cylinder and the fittings immediately associated with it.
MAINTENANCE AND INSPECTION
Installationand commissioning of the fuel supply system should be carried out by
competent persons adequately trained on LPG installation work on engines and
in boats who are conversant with the properties of LPG.
STORAGE – REPAIR AND MAINTENANCE
Craft fuelled with LPG may be parked, service and repaired inside workshops
provided that the following conditions are observed:
1. Only trained and competent personnel on the use of LPG as a fuel for boats
should be allowed to work on the craft’s engine or fuel system.
2. There shall be no leaks in the fuel system and the fuel containers shall not be
filled beyond the 80 % maximum level.
3. Craft shall not be positioned within 3 m of sources of heat, open flames or other
sources of ignition.
4. Unless the fuel is required for engine operation, LPG fuelled craft being
repaired in workshops shall have the fuel container(s) shutt–off valve closed
and the LPG fuel in the service line exhausted by running the engine or, if this
is not possible, by disconnecting, in the open air, where the LPG cannot
accumulate.
5. Craft undergoing repairs involving welding or the application heat, to any part
within 1m of the fuel container, shall have the fuel lines emptied as (d) and the
fuel container removed or shielded from the source of heat.
6. If the craft is to be repaired over an open pit, the pit shall be adequately
ventilated.It is recommended that lighting needs to be safe to use in the area
and that gas detectors are permanently fitted at the bottom pf the pit. These
should be checked daily.
EMERGENCY PROCEDURES
The emergency action taken depends upon the situation is categorised as:
1. Leakage of LPG without fire.
2. Leakage of LPG which has ignited.
3. Fire external to containers or appliances.
EMERGENCY PROCEDURES
Leakageof LPG without Fire
Because LPG is normally stenched, a leakage will normally be detected by smell
but can be detected by an automatic gas detector, if fitted.
If leakage of LPG is suspected or detected, the following action should be taken
immediately.
1. Shut down the engine.
2. Do not operate other electric switches.
3. Shut off the supply of gas by closing the main container valve(s).
4. Extinguishing all naked flames and other sources of ignition, e.g heaters,
cookers, pilot lights, cigarettes, etc.
5. Ventilate by creating a through draught to disperse gas.
6. If possible, evacuate the area because leak with no fire may form an explosive
mixture.
7. If leakage cannot be stopped remove containers from the vessel to a safe
place, preferably in the open air. Place the container in a position on deck
where the leaking gas will be blown away from other vessels in the vicinity.
Extreme care should be taken to remove the container and/or the
self–containedappliance in such a way as to prevent spillage of liquid.
8. Do not use the installation again until it has been checked and, if necessary,
the fault rectified by a competent person.

BOATS, YACHTS AND OTHER CRAFT
LeakageOf LPG which Has Ignited
Action will depend upon whether the boat is 1at a landing or 2off–shore.
1At a landing:
1. Raise the alarm and if practicable, call the fire brigade.
2. Alert everyone in the vicinity and, if possible, evacuate the area.
3. It is safe to do so, the flame should be extinguished by shutting off the supply
gas, preferably by closing the container valve. No attempt should be made to
extinguish the flame in any other way. After closing the container valve use
extinguishers provided or water from over the side for free fires.
4. Inform the fire brigade on arrival of the location of the gas container.
5. Do not use the installation again until it has been checked and rectified by a
competent person.
2Off–Shore
1. Alert everyone on board.
2. Close the container valve(s), use extinguishers provided or water from over
the side for free burning fires.
3. Do not use the installation again until it has been checked and rectified by a
competent person.
Fire External To Containers Or Appliances
If there is a fire external to a LPG container or self–appliances, which has or could
spread to the container, the following action should be taken.
1. Alert everyone on board. Anyone not fighting the fire should, if possible, leave
the boat.
2. Close the container valves and, if safe and possible to do so, remove
containers to a safe place in the open air.
3. If containers cannot be removed, it is essential that every effort is made to keep
them cool by covering with wet blankets, etc. and spraying with water.
4. Do not use the installation again until it has been checked and rectified by a
competent person.

FASTENING SECURITY LINE
4The primary purpose for installing a security line is to prevent loss of the
outboard if the outboard becomes detached from the boat transom.
An effective security line should be of a working strength of at least five times the
weight of the outboard.
The security line should be attached between the boat and outboard following one
of these steps.
Step 1. The length of the security line should be short enough and affixed in a
manner to prevent the outboard from rising up and disengaging off the boat
transom.
Step 2. The length of the security line should be long enough and affixed in a
manner to permit a detached outboard to submerge completely behind the boat
and stop running but not too short that could allow the outboard to continue running
and propel itself back into the boat.
WARNING
If the length of security line being used is long enough to allow the out-
board to disengage off the boat transom but is too short to not allow the
outboard to submerge behind the boat and stop running, the outboard
could continue running and propel itself back into the boat with the pro-
peller rotating under power. This exposes the occupants to serious injury
or death.

vent (b) after engine has stopped.
2Remote fuel tank models – With the outboard still in the water, disconnect the
remote fuel line and run engine until it stops, draining carburetor. Install the
protector cap (a) over the fuel connector.
3Remove outboard and hold upright until the water is drained out. Keep the
outboard in a upright position when carrying.
4Carry, transport or store the outboard only in the upright position (a ) or tiller
handle down position (b). These positions will prevent oil from draining out of
the crankcase.
5Never carry, store or transport the outboard in these positions. Engine damage
could result from oil draining out of the crankcase.

TRAILERING YOUR BOAT
IMPORTANT: The tilt lock mechanism is not intended to support the
outboard up in the tilted position when trailering your boat. Use of the tilt
lock mechanism could allow the outboard to bounce and drop down
causing damage to the outboard.
1Your boat should be trailered with the outboard tilted down (normal operating
position).
2If additional ground clearance is required, remove the outboard from the boat
and store securely. Additional clearance may be needed for railroad crossings,
driveways, and trailer bouncing.
3Set the gear shift into forward gear. This prevents the propeller from spinning
freely.

GASOLINE RECOMMENDATIONS
United States and Canada
Use a major brand of automotive unleaded gasoline with a minimum posted octane
rating of 87. Mid-grade automotive gasolines that contain fuel injector cleaner are
preferred for added internal engine cleanliness. Leaded gasoline is not
recommended.
International
Use a major brand of automotive unleaded gasoline with a minimum posted octane
rating of 90RON. Automotive gasolines that contain fuel injector cleaner are
preferred for added internal engine cleanliness. Leaded gasoline is acceptable in
areas where unleaded gasoline is not available.
Alcohol in Gasoline
We do not recommend the use of gasoline which contains alcohol because of the
possible adverse effect the alcohol may have on the fuel system. In general, if only
gasoline containing alcohol is available, it must not contain more than 10% ethanol
or 5% methanol, and the addition of a Water Separating Fuel Filter is
recommended.
If gasoline containing alcohol is used or if you suspect the presence of alcohol in
your gasoline, increase your inspection of the fuel system, visually checking for
fuel leaks or abnormalities.
Gasoline containing alcohol may cause the following problems to your outboard
and fuel system:
•Corrosion of metal parts.
•Deterioration of elastomers and plastic parts.
•Wear and damage of internal engine parts.
•Starting and operating difficulties.
•Vapor lock or fuel starvation.
Some of these adverse effects are due to the tendency of gasoline containing
alcohol to absorb moisture from the air, resulting in a phase of water and alcohol
which separates from the gasoline in the fuel tank.
The adverse effects of alcohol are more severe with methanol and are worse with
increasing content of alcohol.
oee8
FILLING FUEL TANK
WARNING
Avoid serious injury or death from a gasoline fire or explosion. Always
stop the engine and DO NOT smoke or allow open flames or sparks in the
area while filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Remove portable fuel tanks from boat to refill them.
Always stop engine before refilling tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of the tank volume
unfilled.Fuel will expand in volume as its temperature rises and can leak under
pressure if the tank is completely filled.
Portable Fuel Tank Placement in the Boat
Place the fuel tank in the boat so that the tank vent will stay higher than the fuel
level in the tank under normal boat operating conditions.
Portable LPG Cylinder Placement In the Boat
Place the portable LPG Cylinder in the boat so that the cylinder valve will stay
higher than the LPG level in the tank under normal boat operating conditions.
LPG RECOMMENDATIONS
LPG usage as a fuel for engines is a mixture primarily made up of Butane and
Propane in variable proportions. Those can vary according to the distributive firms
and the seasons so as to allow a starting of the engine under the best conditions.
In general the percentage of propane is highest in winter so as to facilitate cold
start.

ENGINE OIL RECOMMENDATIONS
We recommend the use of Mercury or Quicksilver SAE 10W–30 multi–viscosity
4–stroke outboard oil for general, all–temperature use. If SAE 25W–40
multi–viscosity oil is preferred, (see chart above) use Mercury MerCruiser 4–cycle
engine oil or Quicksilver sterndrive & inboard 4–cycle engine oil. Never use
4–cycle engine oil that is not certified to meet or exceed any one or combination
of the American Petroleum Institute (API) Service Classification SH, SG, SF,
CF–4, CE, CD, CDII. Severe engine damage may result from use of an inferior oil.
RecommendedSAE Viscosity For Engine Oil
•SAE 10W-30 viscosity oil is recommended for use in all temperatures.
•SAE 25W-40 viscosity oil may be used at temperatures above 40°F (4°C).

CHECKING ENGINE OIL
IMPORTANT: Do not overfill. Be sure that the outboard is upright (not tilted)
when checking oil.
1Position the outboard vertical and remove the top cowl.
2Remove the oil filler cap. Wipe oil off the dip stick and screw the oil filler cap
back into the oil fill hole completely. Remove the oil filler cap and check oil level
on dipstick. Oil must be between full mark (a) and add mark (b). If oil level is
low, add oil to bring oil level no higher than full mark (a).
Note: If oil level is at the add mark (b), add 3 oz. (100 mL) of oil.
IMPORTANT: Inspect oil for signs of contamination. Oil contaminated with
water will have a milky color to it; oil contaminated with fuel will smell
strongly of fuel. If contaminated oil is noticed, have the engine checked by
your dealer.
3Reinstall the oil filler cap and tighten securely.

OPERATING IN FREEZING TEMPERATURES
When using your outboard or having your outboard moored in freezing or near
freezing temperature, keep the outboard tilted down at all times so the gear case
is submerged. This prevents trapped water in the gear case from freezing and
causing possible damage to the water pump and other components.
If there is a chance of ice forming on the water, the outboard should be removed
and drained completely of water. If ice should form at the water level inside the
outboard drive shaft housing, it will block water flow to the engine causing possible
damage.
one3
OPERATING IN SALT WATER OR POLLUTED WATER
We recommend that you flush the internal water passages of your outboard with
fresh water after each use in salt or polluted water. This will prevent a buildup of
deposits from clogging the water passages. Refer to “Flushing The Cooling
System” procedure in the Maintenance Section.
If you keep your boat moored in the water, always tilt the outboard so the gear case
is completely out of water (except in freezing temperature) when not in use.
Wash down the outboard exterior and flush out the exhaust outlet of the propeller
and gear case with fresh water after each use. Each month, spray Mercury
Precision or Quicksilver Corrosion Guard on external metal surfaces (do not spray
on corrosion control anodes as this will reduce the effectiveness of the anodes).
