WARRANTY INFORMATION
CONDITIONS THAT MUST BE MET IN ORDER TO OBTAIN
WARRANTY COVERAGE: Warranty coverage is available only
to retail customers that purchase from a Dealer authorized by
Mercury Marine to distribute the product in the country in which
the sale occurred, and then only after the Mercury Marine
specified predelivery inspection process is completed and
documented. Warranty coverage becomes available upon proper
registration of the product by the authorized dealer. Inaccurate
warranty registration information regarding recreational use, or
subsequent change of use from recreational to commercial
(unless properly reregistered) may void the warranty at the sole
discretion of Mercury Marine. Routine maintenance outlined in
the Operation and Maintenance Manual must be timely
performed in order to maintain warranty coverage. Mercury
Marine reserves the right to make warranty coverage contingent
upon proof of proper maintenance.
WHAT MERCURY WILL DO: Mercury's sole and exclusive
obligation under this warranty is limited to, at our option,
repairing a defective part, replacing such part or parts with new
or Mercury Marine certified remanufactured parts, or refunding
the purchase price of the Mercury product. Mercury reserves the
right to improve or modify products from time to time without
assuming an obligation to modify products previously
manufactured.
eng
WARRANTY INFORMATION
HOW TO OBTAIN WARRANTY COVERAGE: The customer
must provide Mercury with a reasonable opportunity to repair,
and reasonable access to the product for warranty service.
Warranty claims shall be made by delivering the product for
inspection to a Mercury dealer authorized to service the product.
If purchaser cannot deliver the product to such a dealer, written
notice must be given to Mercury. We will then arrange for the
inspection and any covered repair. Purchaser, in that case, shall
pay for all related transportation charges and/or travel time. If the
service provided is not covered by this warranty, purchaser shall
pay for all related labor and material, and any other expenses
associated with that service. Purchaser shall not, unless
requested by Mercury, ship the product or parts of the product
directly to Mercury. Proof of registered ownership must be
presented to the dealer at the time warranty service is requested
in order to obtain coverage.
eng
WARRANTY INFORMATION
WHAT IS NOT COVERED: This limited warranty does not cover
routine maintenance items, tuneups, adjustments, normal wear
and tear, damage caused by abuse, abnormal use, use of a
propeller or gear ratio that does not allow the engine to run in its
recommended wideopen throttle RPM range (see the Operation
and Maintenance Manual), operation of the product in a manner
inconsistent with the recommended operation/duty cycle section
of the Operation and Maintenance Manual, neglect, accident,
submersion, improper installation (proper installation
specifications and techniques are set forth in the installation
instructions for the product), improper service, use of an
accessory or part not manufactured or sold by us, jet pump
impellers and liners, operation with fuels, oils or lubricants which
are not suitable for use with the product (see the Operation and
Maintenance Manual), alteration or removal of parts, water
entering the engine through the fuel intake, air intake or exhaust
system, or damage to the product from insufficient cooling water
caused by blockage of the cooling system by a foreign body,

the transom, or running the boat with the engine trimmed out too
far. Use of the product for racing or other competitive activity, or
operating with a racing type lower unit, at any point, even by a
prior owner of the product, voids the warranty.
Expenses related to haulout, launch, towing, storage, telephone,
rental, inconvenience, slip fees, insurance coverage, loan
payments, loss of time, loss of income, or any other type of
incidental or consequential damages are not covered by this
warranty. Also, expenses associated with the removal and/or

WARRANTY INFORMATION
WHAT IS COVERED: Mercury Marine warrants the components
of the emissions control systems (see the components listed in
the Emission Control System Components) of its new, 2001
model year and later outboards, sold by a California dealer to
retail customers residing in California, to be free from defects in
material or workmanship, that cause the failure of a warranted
part to be identical in all material respects to that part as
described in the application of Mercury Marine for certification
from the California Air Resources Board, for the period of time,
and under the conditions, identified below. The cost to diagnose
a warranty failure is covered under the warranty (if the warranty
claim is approved). Damage to other engine components caused
by the failure of a warranted part will also be repaired under
warranty.
DURATION OF COVERAGE: This limited warranty provides
coverage for the components of the emissions control systems of
new, 2001 model year and later outboards, sold to retail
customers in California for four (4) years from either the date the
product is first sold, or first put into service, whichever occurs

determined by the engine's hour meter, if any). Emissionrelated
normal maintenance items such as spark plugs and filters, that
are on the warranted parts list, are warranted up to their first
required replacement interval only. Refer to Emission Control
System Components and Maintenance Schedule. The repair or
replacement of parts, or the performance of service under this
warranty, does not extend the life of this warranty beyond its
original expiration date. Unexpired warranty coverage can be
transferred to a subsequent purchaser. (See instructions on
transfer of warranty.)

WARRANTY INFORMATION
California Air Resources Board Explanation of
Your California Emission Control Warranty
Statement
YOUR WARRANTY RIGHTS AND OBLIGATIONS: The
California Air Resources Board is pleased to explain the
emission control system warranty on your 2001 model year and
later outboard engine. In California, new outboard engines must
be designed, built, and equipped to meet the State's stringent
antismog standards. Mercury Marine must warrant the emission
control system on your outboard engine for the periods of time
listed below, provided there has been no abuse, neglect, or
improper maintenance of your outboard engine.
Your emission control system may include parts such as the
carburetor or fuel injection system, the ignition system, and
catalytic converter. Also included may be hoses, belts,
connectors, and other emissionrelated assemblies.
Where a warrantable condition exists, Mercury Marine will repair
your outboard engine at no cost to you, including diagnosis,
parts, and labor.
MANUFACTURER'S WARRANTY COVERAGE: Select emission
control parts from model year 2001 and later outboard engines
are warranted for four (4) years, or for 250 hours of use,
whichever occurs first. However, warranty coverage based on
the hourly period is only permitted for outboard engines and
personal watercraft equipped with appropriate hour meters or
their equivalent. If any emissionrelated part on your engine is
defective under warranty, the part will be repaired or replaced by
Mercury Marine.
OWNER'S WARRANTY RESPONSIBILITIES: As the outboard
engine owner, you are responsible for the performance of the
required maintenance listed in the Maintenance section.
Mercury Marine recommends that you retain all receipts covering
maintenance on your outboard engine, but Mercury Marine
cannot deny warranty solely for the lack of receipts or your
failure to ensure the performance of all scheduled maintenance.
18
eng
WARRANTY INFORMATION
As the outboard engine owner, you should, however, be aware
that Mercury Marine may deny you warranty coverage if your
outboard engine or a part has failed due to abuse, neglect,
improper maintenance, or unapproved modifications.
You are responsible for presenting your outboard to a Mercury
dealer authorized to service the product as soon as a problem
exists. The warranty repairs will be completed in a reasonable
amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and
responsibilities, you should contact Mercury Marine at

Propeller Selection
The propeller on your outboard is one of the most important
components in the propulsion system. An improper propeller
choice can significantly affect the performance of your boat and
could result in damage to the outboard engine.
When choosing a propeller, a full selection of aluminum and
stainless steel propellers specifically designed for your outboard
are available through Mercury Marine. To view the entire product
offering and find the correct propeller that is best suited for your
application, visit www.mercmarinepropellers.com or see your
local authorized Mercury dealer.
eng
29
GENERAL INFORMATION
Propellers are designated by the diameter, pitch, number of
blades, and material. The diameter and pitch are stamped (cast)
into the side or the end of the propeller hub. The first number
represents the diameter of the propeller and the second number
represents the pitch. For example, 14x19 represents a propeller
with a 14 inch diameter and 19 inches of pitch.
a
22669
a - Diameter
b - Pitch Travel during one revolution
The following are some propeller basics that will help you
determine the correct propeller for your boating application.
Diameter The diameter is the distance across the imaginary
circle that is made when the propeller rotates. The correct
diameter for each propeller has been predetermined for the
design of your outboard. However, when more than one
diameter is available for the same pitch, use a larger diameter for
heavy boat applications and a smaller diameter for lighter
applications.
Pitch The pitch is the theoretical distance, in inches, that a
propeller travels forward during one revolution. Pitch can be
thought of similar to gears in a car. The lower the gear, the faster
the car will accelerate, but with lower overall top speed.
Likewise, a lower pitch propeller will accelerate quickly, but
topend speed will be reduced. The higher the propeller pitch the
faster the boat will usually go; though typically slowing
acceleration.
30
eng
GENERAL INFORMATION
Determining the correct pitch size First, check the full throttle
RPM under normal load condition. If the full throttle RPM is
within the recommended range, select a replacement or upgrade
propeller with the same pitch as the current propeller.
Adding 1 inch of pitch will reduce the full throttle RPM by
150 to 200
Subtracting 1 inch of pitch will increase full throttle RPM by
150 to 200
Upgrading from a 3blade propeller to a 4blade propeller
will generally decrease full throttle RPM by 50 to 100
IMPORTANT: Avoid damage to the engine. Never use a
propeller which allows the engine to exceed the recommended
full throttle RPM range when under normal full throttle operation.
PROPELLER MATERIAL
Most propellers manufactured by Mercury Marine are made from
either aluminum or stainless steel. Aluminum is suitable for
general purpose use and is standard equipment on many new
boats. Stainless steel is over five times more durable than
aluminum and typically provides performance gains in
acceleration and top end speed due to design efficiencies.
Stainless steel propellers also come in a larger variety of sizes
and styles that allow you to dial in the ultimate performance for
your boat.
3 BLADE VS. 4 BLADE
Available in many sizes of both aluminum and stainless, 3 and
4blade propellers have unique performance characteristics. In
general, 3blade propellers offer good all around performance
and higher top speed than 4blade propellers. However, 4blade
propellers are usually faster to plane and more efficient at
cruising speeds, but lack the top end speed of a 3blade
propeller.

GENERAL INFORMATION
Outboard Remote Control Models
The remote control connected to your outboard must be
equipped with a start in neutral only protection device. This
prevents the engine from starting when the shift is actuated in
any position other than neutral.
! WARNING
Starting the engine with the drive in gear can cause serious
injury or death. Never operate a boat that does not have a
neutralsafetyprotection device.

GENERAL INFORMATION
! WARNING
Improper fasteners or improper installation procedures can
result in loosening or disengagement of the steering link rod.
This can cause a sudden, unexpected loss of boat control,
resulting in serious injury or death due to occupants being
thrown within or out of the boat. Always use required
components and follow instructions and torque procedures.

GENERAL INFORMATION
The lanyard is a cord usually 122152 cm (45 feet) in length
when 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 atrest condition
as short as possible to minimize the likelihood of lanyard
entanglement with nearby objects. Its stretchedout length is
made 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.
21629
a - Lanyard cord
b - Lanyard stop switch
Read the following Safety Information before proceeding.
34
eng
GENERAL INFORMATION
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.
Falling overboard and accidental ejections are more likely to
occur in certain types of boats such as low sided inflatables,
bass boats, high performance boats, and light, sensitive handling
fishing boats operated by a hand tiller. Falling overboard and
accidental ejections 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 planing speeds, 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.
While activation 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 (if the operator
is accidentally ejected).
! WARNING
If the operator falls out of the boat, stop the engine immediately
to reduce the possibility of serious injury or death from being
struck by the boat. Always properly connect the operator to the
stop switch using a lanyard.
eng
35
GENERAL INFORMATION
! WARNING
Avoid serious injury or death from deceleration forces resulting
from accidental 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.
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:
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 gearcase or propeller.
Loss of power and directional control in heavy seas, strong
current, or high winds.
Loss of control when docking.

GENERAL INFORMATION
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.
21604
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.
! WARNING
A spinning propeller, a moving boat, or any solid device
attached to the boat can cause serious injury or death to
swimmers. Stop the engine immediately whenever anyone in
the water is near your boat.
Shift the outboard into neutral and shut off the engine before
allowing people to swim or be in the water near your boat.
eng
37
GENERAL INFORMATION
Passenger Safety Message Pontoon Boats and
Deck Boats
Whenever the boat is in motion, observe the location of all
passengers. Do not allow any passengers to stand or use seats
other than those designated for traveling faster than idle speed.
A sudden reduction in boat speed, such as plunging into a large
wave or wake, a sudden throttle reduction, or a sharp change of
boat direction, could throw them over the front of the boat.
Falling over the front of the boat between the two pontoons will
position them to be run over by the outboard.
26782
! WARNING
Sitting or standing in an area of the boat not designed for
passengers at speeds above idle can cause serious injury or
death. Stay back from the front end of deck boats or raised
platforms and remain seated while the boat is in motion.
38
eng
GENERAL INFORMATION
BOATS WITH FRONT MOUNTED, RAISED PEDESTAL
FISHING SEATS
Elevated fishing seats are not intended for use when the boat is
traveling faster than idle or trolling speed. Sit only in seats
designated for traveling at faster speeds.
Any unexpected, sudden reduction in boat speed could result in
the elevated passenger falling over the front of the boat.
26783
26784
eng
39
GENERAL INFORMATION
! WARNING
Wave or wake jumping can cause serious injury or death from
occupants being thrown within or out of the boat. Avoid wave
or wake jumping whenever possible.
There is another less common hazardous result from allowing
your boat to launch off a wave or wake. If the bow of your boat
pitches down far enough while airborne, upon water contact it
may penetrate under the water surface and submarine for an
instant. This will bring the boat to a nearly instantaneous stop
and can send the occupants flying forward. The boat may also
steer sharply to one side.

GENERAL INFORMATION
Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a deadly gas that is present in the
exhaust fumes of all internal combustion engines, including the
engines that propel boats, and the generators that power boat
accessories. By itself, CO is odorless, colorless, and tasteless,
but if you can smell or taste engine exhaust, you are inhaling
CO.
Early symptoms of carbon monoxide poisoning, which are similar
to the symptoms of seasickness and intoxication, include
headache, dizziness, drowsiness, and nausea.
! WARNING
Inhaling engine exhaust gases can result in carbon monoxide
poisoning, which can lead to unconsciousness, brain damage,
or death. Avoid exposure to carbon monoxide.
Stay clear from exhaust areas when engine is running. Keep
the boat wellventilated while at rest or underway.
41127
eng
GENERAL INFORMATION
GOOD VENTILATION
Ventilate the passenger area, open side curtains or forward
hatches to remove fumes.
Example of desired air flow through the boat:
21622
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 open area of a stationary boat that
contains, or is near, a running engine may be exposed to a
hazardous level of carbon monoxide.
1. Examples of poor ventilation while the boat is stationary:

TRANSPORTING
Trailering Boat/Outboard
Trailer your boat with the outboard tilted down in a vertical
operating position.
If additional ground clearance is required, the outboard should
be tilted up using an accessory outboard support device. Refer
to your local dealer for recommendations. Additional clearance
may be required for railroad crossings, driveways, and trailer
bouncing.

FUEL RATINGS
Mercury Marine engines will operate satisfactorily when using a
major brand of unleaded gasoline meeting the following
specifications:
USA and Canada having a posted pump octane rating of 87 (R
+M)/2 minimum. Premium gasoline (92 [R+M]/2 octane) is also
acceptable. Do not use leaded gasoline.
Outside USA and Canada having a posted pump octane
rating of 90 RON minimum. Premium gasoline (98 RON) is also
acceptable. If unleaded gasoline is not available, use a major
brand of leaded gasoline.
USING REFORMULATED (OXYGENATED) GASOLINES
(USA ONLY)
This type of gasoline is required in certain areas of the USA. The
two types of oxygenates used in these fuels are alcohol (ethanol)
or ether (MTBE or ETBE). If ethanol is the oxygenate that is
used in the gasoline in your area, refer to Gasolines Containing
Alcohol.
These reformulated gasolines are acceptable for use in your
Mercury Marine engine.
GASOLINES CONTAINING ALCOHOL
If the gasoline in your area contains either methanol (methyl
alcohol) or ethanol (ethyl alcohol), you should be aware of
certain adverse effects that can occur. These adverse effects are
more severe with methanol. Increasing the percentage of alcohol
in the fuel can also worsen these adverse effects.
Some of these adverse effects are caused because the alcohol
in the gasoline can absorb moisture from the air, resulting in a
separation of the water/alcohol from the gasoline in the fuel tank.
52
eng
! WARNING
Fuel leakage is a fire or explosion hazard, which can cause
serious injury or death. Periodically inspect all fuel system
components for leaks, softening, hardening, swelling, or
corrosion, particularly after storage. Any sign of leakage or
deterioration requires replacement before further engine
operation.
Because of possible adverse effects of alcohol in gasoline, it is
recommended that only alcoholfree gasoline be used where
possible. If only fuel containing alcohol is available, or if the
presence of alcohol is unknown, increased inspection frequency
for leaks and abnormalities is required.
IMPORTANT: When operating a Mercury Marine engine on
gasoline containing alcohol, storage of gasoline in the fuel tank
for long periods should be avoided. Long periods of storage,
common to boats, create unique problems. In cars, alcoholblend
fuels normally are consumed before they can absorb enough
moisture to cause trouble, but boats often sit idle long enough for
phase separation to take place. In addition, internal corrosion
may take place during storage if alcohol has washed protective
oil films from internal components.
eng
53
Fuel Additives
To minimize carbon deposit buildup in the engine, it is
recommended to add Mercury or Quicksilver Quickleen Engine
Treatment additive to the engine's fuel at each tank fill
throughout the boating season. Use additive as directed on
container.

When installing the fuel tank cap, turn the cap to the right
until you hear a click. This signals that the fuel cap is fully
seated. A builtin device prevents overtightening.
The fuel tank has a manual vent screw which should be
closed for transportation and open for operation and cap
removal.
Since sealed fuel tanks are not vented, they will expand and
contract as the fuel expands and contracts during heating and
cooling cycles of the outside air. This is normal.

! WARNING
Trimming the outboard beyond a neutral steering condition
may result in a pull on the steering wheel or tiller handle and
loss of boat control. Maintain control of the boat if trimming
beyond a neutral steering condition.
Consider the following lists carefully.
1. Trimming in or down can:
Lower the bow.
Result in quicker planing off, especially with a heavy load
or a stern heavy boat.
Generally improve the ride in choppy water.
Increase steering torque or pull to the right (with the
normal righthand rotation propeller).
In excess, can lower the bow of some boats to a point
where they begin to plow with their bow in the water while
on plane. This can result in an unexpected turn in either
direction (called bow steering or oversteering) if any turn
is attempted, or if a significant wave is encountered.
eng
65
TILTING OPERATION
To tilt the outboard, shut off the engine and press the trim/tilt
switch or auxiliary tilt switch to the up position. The outboard will

Gearcase Lubrication
When adding or changing gearcase lubricant, visually check for
the presence of water in the lubricant. If water is present, it may
have settled to the bottom and will drain out prior to the lubricant,
or it may be mixed with the lubricant, giving it a milky colored
appearance. If water is noticed, have the gearcase checked by
your dealer. Water in the lubricant may result in premature
bearing failure or, in freezing temperatures, will turn to ice and
damage the gearcase.
Examine the drained gearcase lubricant for metal particles. A
small amount of metal particles indicates normal gear wear. An
excessive amount of metal filings or larger particles (chips) may
indicate abnormal gear wear and should be checked by an
authorized dealer.

SUBMERGED OUTBOARD
A submerged outboard will require service within a few hours by
an authorized dealer once the outboard is recovered from the
water. This immediate attention by a servicing dealer is
necessary once the engine is exposed to the atmosphere to
minimize internal corrosion damage to the engine.
eng

STORAGE
Storage Preparation
The major consideration in preparing your outboard for storage is
to protect it from rust, corrosion, and damage caused by freezing
of trapped water.
The following storage procedures should be followed to prepare
your outboard for out of season storage or prolonged storage
(two months or longer).
NOTICE
Without sufficient cooling water, the engine, the water pump,
and other components will overheat and suffer damage.
Provide a sufficient supply of water to the water inlets during
operation.
Fuel System
IMPORTANT: Gasoline containing alcohol (ethanol or methanol)
can cause a formation of acid during storage and can damage
the fuel system. If the gasoline being used contains alcohol, it is
advisable to drain as much of the remaining gasoline as possible
from the fuel tank, remote fuel line, and engine fuel system.
The most effective method of storage preparation is to add the
recommended amount of Mercury Precision Fuel Stabilizer and
Mercury Precision Quickleen products as described on the
containers to the fuel tank before the last operation of the boat.
Adding fuel stabilizer will help prevent the formation of varnish
and gum in the gasoline. The Mercury Precision Quickleen
product will help clean and lubricate the fuel injectors.
1. Portable fuel tank Pour the required amount of gasoline
stabilizer and Quickleen (follow instructions on containers)
into fuel tank. Tip fuel tank back and forth to mix stabilizer
and Quickleen with the fuel.
2. Permanently installed fuel tank Pour the required amount
of gasoline stabilizer and Quickleen (follow instructions on
containers) into a separate container and mix with
approximately 1 liter (1 US qt) of gasoline. Pour this mixture
into fuel tank.

priming process.
Trim In Pin
! WARNING
Operating the boat at high speeds with the outboard trimmed
too far under can create excessive bow steer, resulting in the
operator losing control of the boat. Install the trim limit pin in a
position that prevents excessive trim under and operate the
boat in a safe manner.
Some boats, particularly some bass boats, are built with a
greater than normal transom angle, which will allow the outboard
to be trimmed further in or under. This greater trim under
capability is desirable to improve acceleration, reduce the angle
and time spent in a bow high boat during planing off, and in
some cases, may be necessary to plane off a boat with aft
livewells, given the variety of available propellers and height
range of engine installations.

However, once on plane, the engine should be trimmed to a
more intermediate position to avoid a bowdown planing
condition called plowing. Plowing can cause bow steering or
oversteering and inefficiently consumes horsepower.

The owner may decide to limit the trim in. This can be
accomplished by purchasing a stainless steel tilt pin from your
dealer and insert it in whatever adjustment hole in the transom
brackets is desired. A nonstainless steel shipping bolt should not
be used in this application other than on a temporary basis.
