CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
INTRODUCTION
The California Air Resources Board has promulgated air emissions
regulations for inboard and sterndrive engines. The regulations
apply to all inboard and sterndrive engines that were manufactured
for the 2014 and 2015 model year. Mercury Racing, in compliance
with those regulations, provides this limited warranty for the
emission control systems (see the components of the emission
control system listed following), and further warrants that the inboard
or sterndrive engine was designed, built, and equipped to conform
with all applicable regulations adopted by the California Air
Resources Board pursuant to its authority in Chapters 1 and 2, Part
5, Division 26 of the Health and Safety Code. For information

Mercury Racing warrants the components of the emissions control
systems (see the components of the emission control system listed
following) of its new, 2009 model year and later California‑certified
high performance sterndrive engines, registered to a California
resident, 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
Racing 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 if the warranty claim is
approved. Damage to other engine components caused by the

the engine’s ECM‑integrated hour meter), whichever first occurs for
engines greater than 500 horsepower and less than or equal to 650
horsepower and for a period of 1 year or 50 hours (as determined by
the engine’s ECM‑integrated hour meter), whichever first occurs for
engines greater than 650 horsepower. Emission related 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. Refer to Transfer of Warranty.

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 2013‑2014 model year
sterndrive engine. In California, new sterndrive engines must be
designed, built and equipped to meet the State's stringent antismog

system on your sterndrive engine for the periods of time listed
below, provided there has been no abuse, neglect, or improper
maintenance of your sterndrive 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
emission‑related assemblies. Where a warrantable condition exists,
Mercury Marine will repair your sterndrive engine at no cost to you,
including diagnosis, parts and labor.
MANUFACTURER'S WARRANTY COVERAGE
Select electronic emission‑related control parts from model year
2009 and later sterndrive engines are warranted for three years or
480 hours, whichever first occurs. Select mechanical

horsepower. However, warranty coverage based on the hourly
period is only permitted for engines that are equipped with hour
meters as defined in s 2441(a)(13) or their equivalent. If any
emission‑related part on your engine is defective under warranty,
the part will be repaired or replaced by Mercury Racing.
OWNER'S WARRANTY RESPONSIBILITIES
As the sterndrive engine owner, you are responsible for the
performance of the required maintenance listed in your owner's
manual. Mercury Racing recommends that you retain all receipts
covering maintenance on your sterndrive engine, but Mercury
Racing cannot deny warranty solely for the lack of receipts or your
failure to ensure the performance of all scheduled maintenance.
As the sterndrive engine owner, you should however be aware that
Mercury Racing may deny you warranty coverage if your sterndrive
engine or a part has failed due to abuse, neglect, improper
maintenance, or unapproved modifications.
You are responsible for presenting your sterndrive engine to a
Mercury Marine distribution center 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

The 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. A lanyard stop switch can be installed as an accessory ‑
generally on the dashboard or side adjacent to the operator's
position.

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.

b - Lanyard stop switch
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
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.

! 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 gear case or propeller.
• Loss of power and directional control in heavy seas, strong
current or high winds.
• Loss of control when docking.
TRAILERING THE BOAT
The boat can be trailered with the drive unit in up or down position.
Adequate road clearance is required between road and gear
housing skeg when trailering with the drive unit in down position.
If adequate road clearance is a problem, place drive unit in full up
position.

PROTECTING PEOPLE IN THE WATER
WHILE YOU ARE CRUISING
It is very difficult for a person in the water to take quick action to
avoid a boat heading in their direction, even at slow speeds.
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 (even coasting) and the gear shift is in
neutral, 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
! 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 into neutral and shut off the engine before allowing people to
swim or be in the water near your boat.
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 well‑ventilated while at rest or underway.

Engine exhaust gases contain harmful carbon monoxide. Avoid
areas of concentrated engine exhaust gases. When engines are
running, keep swimmers away from the boat, and do not sit, lie, or
stand on swim platforms or boarding ladders. While underway, do
not allow passengers to be positioned immediately behind the boat
(platform dragging, teak/body surfing). This dangerous practice not
only places a person in an area of high engine exhaust
concentration, but also subjects them to the possibility of injury from
the boat propeller.
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:
a - Operating the engine when the boat is moored in a
confined space
b - Mooring close to another boat that has its engine
operating
2. Examples of poor ventilation while the boat is moving:
a - Operating the boat with the trim angle of the bow too high
b - Operating the boat with no forward hatches open (station
wagon effect)

WAVE AND WAKE JUMPING
Operating recreational boats over waves and wake is a natural part
of boating. However, when this activity is done with sufficient speed
to force the boat hull partially or completely out of the water, certain
hazards arise, particularly when the boat enters the water.
5450
The primary concern is the boat changing direction while in the
midst of the jump. In such case, the landing may cause the boat to
veer violently in a new direction. Such a sharp change in direction
can cause occupants to be thrown out of their seats, or out of the
boat.
! 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.
IMPACT WITH UNDERWATER HAZARDS
IMPORTANT: Operating in shallow waters can severely damage the
boat or power package. Maintain a minimum safe speed when
operating the vessel in shallow waters or in areas with underwater
obstacles.
Reduce speed and proceed with caution whenever you drive a boat
in shallow water areas, or in areas where you suspect underwater
obstacles may exist which could be struck by the sterndrive or the
boat bottom. The most important thing you can do to help reduce
injury or impact damage from striking a floating or underwater object
is to control the boat speed. Under these conditions, boat speed
should be kept to a minimum planing speed 24 to 40 km/h
(15 to 25 MPH).
45914
Striking a floating or underwater object could result in an infinite
number of situations. Some of these situations could result in the
following:
• Part of the sterndrive or the entire sterndrive could break
loose and cause serious injury or damage to the boat.
