What is Covered
Mercury Marine warrants its new products to be free of defects in material and workmanship during the period described following.
Duration of Coverage
Warranty Period for Recreational Use
The warranty period begins on the date the product is first sold to a recreational‑use retail purchaser or the date on which the
product is first put into service, whichever occurs first. Products installed by an Installation Quality Certified Installer receive one
(1) year of additional warranty coverage. 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. The warranty period is specific to the model covered;
see your model for the base coverage period:
Coverage for Sterndrive Models with Closed Cooling, Inboard Models, Scorpion 377 Models, and Vazer 100
Models The Limited Warranty for Sterndrive Models with Closed Cooling, Inboard Models, Scorpion 377 Models, and
Vazer 100 Models is four (4) years when installed by an Installation Quality Certified Installer or three (3) years for
noncertified installations.

Installer or three (3) years for noncertified installations.
Coverage for Standard Models

Scorpion 377 Models, Vazer 100 Models, or SeaCore Sterndrive Models, is two (2) years when installed by an Installation
Quality Certified Installer or one (1) year for noncertified installations.
Warranty Period for Commercial Use
The warranty period begins on the date the product is first sold to a commercial‑use retail purchaser or the date on which the
product is first put into service, whichever occurs first. Commercial users of these products receive warranty coverage for either
one (1) year from the date of first retail sale or the accumulation of 500 hours of operation, whichever occurs first. Commercial
use is defined as any work‑related or employment‑related use of the product, or any use of the product that generates income
for any part of the warranty period, even if the product is only occasionally used for such purposes. 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.
Transfer of Coverage
Unexpired warranty coverage can be transferred from one recreational‑use customer to a subsequent recreational‑use customer
upon proper reregistration of the product. Unexpired warranty coverage cannot be transferred either to or from a commercial‑use
customer.
Termination of Coverage

• Repossession from a retail customer
• Purchase at auction
• Purchase from a salvage yard
• Purchase from an insurance company that obtained the product as a result of an insurance claim
Page 4 90-899883179 OCTOBER 2007
Section 1 - Warranty
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 pre‑delivery inspection process specified by Mercury Marine
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
must be performed according to the maintenance schedule in the Operation, Maintenance & Warranty manual in order to obtain
warranty coverage. Mercury Marine reserves the right to make any warranty coverage contingent upon proof of proper maintenance.
What Mercury Marine Will Do
Mercury Marine'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 Marine
product. Mercury Marine reserves the right to improve or modify products from time to time without assuming an obligation to modify
products previously manufactured.
How to Obtain Warranty Coverage
The customer must provide Mercury Marine 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 Marine dealer authorized to service the
product. If the purchaser cannot deliver the product to such a dealer, written notice must be given to Mercury Marine. Mercury Marine
will then arrange for the inspection and any covered repair. The purchaser in that case shall pay for all related transportation charges
and travel time. If the service provided is not covered by this warranty, the purchaser shall pay for all related labor and material and
any other expenses associated with that service. The purchaser shall not, unless requested by Mercury Marine, ship the product or
parts of the product directly to Mercury Marine. Proof of registered ownership must be presented to the dealer at the time warranty
service is requested in order to obtain coverage.
What Is Not Covered
This limited warranty does not cover the following:
• Routine maintenance items
• 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 RPM range (see the Operation,

Section 1 - Warranty
Use of the product for racing or other competitive activity, or operating with a racing‑type lower unit at any point, even by a previous
owner of the product, voids the warranty. Expenses related to haul‑out, 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 or replacement of boat partitions or other material in
order to gain access to the product are not covered by this warranty. No individual or entity, including Mercury Marine authorized
dealers, has been given authority by Mercury Marine to make any affirmation, representation, or warranty regarding the product,
other than those contained in this limited warranty. If such affirmation, representation, or warranty is made, it shall not be enforceable
against Mercury Marine.
DISCLAIMERS AND LIMITATIONS
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY
DISCLAIMED. TO THE EXTENT THAT THEY CANNOT BE DISCLAIMED, THE IMPLIED WARRANTIES ARE LIMITED IN
DURATION TO THE LIFE OF THE EXPRESS WARRANTY. INCIDENTAL AND CONSEQUENTIAL DAMAGES ARE EXCLUDED
FROM COVERAGE UNDER THIS WARRANTY. SOME STATES/COUNTRIES DO NOT ALLOW FOR THE DISCLAIMERS,
LIMITATIONS AND EXCLUSIONS IDENTIFIED ABOVE. AS A RESULT, THEY MAY NOT APPLY TO YOU. THIS WARRANTY
GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER LEGAL RIGHTS WHICH VARY FROM STATE
TO STATE AND COUNTRY TO COUNTRY.

Duration of Coverage
This limited corrosion warranty provides coverage for three (3) years from either the date the product is first
sold, or the date on which the product is first put into service, whichever occurs first. The repair and
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 subsequent
(noncommercial use) purchaser upon proper re‑registration of the product. Warranty coverage is terminated
for used product repossessed from a retail customer, purchased at auction, from a salvage yard, or from an
insurance company that obtained the product as a result of an insurance claim.

Mercury Installation Quality Certification Program
90-899883179 OCTOBER 2007 Page 9
15502
Section 1 - Warranty
Mercury MerCruiser products installed by a Mercury Installation Quality Certified
Manufacturer are Installation Quality certified products and may receive an additional one
(1) year of limited warranty coverage.
The Installation Quality Certification program was developed to recognize MerCruiser
boatbuilder customers who have achieved higher manufacturing standards. It is the first
and only comprehensive manufacturer‑installation certification program in the industry.
The program has three goals:
1. To enhance overall product quality.
2. To improve the boat ownership experience.
3. To enhance overall customer satisfaction.
The certification process is designed to review all facets of manufacturing and engine
installation. The program is composed of design, manufacturing and installation review
stages with which builders must comply. Certification applies leading‑edge methodologies
to create:
• Efficiencies and best practices specific to engine installation.
• World‑class assembly and component specifications.
• Efficient installation processes.
• Industry standard end‑of‑line test procedures
Boat builders that successfully complete the program and meet all certification
requirements earn Installation Quality System Certified Manufacturer status and receive
an additional one (1) year of Mercury limited factory warranty coverage on all
MerCruiser‑powered boats that are registered on and after the boat builder's certification
date for all worldwide registrations.
Mercury has designated a section of our Website to promote the Installation Quality
Certification Program and communicate its benefits to consumers. For a current list of
MerCruiser‑powered boat brands that have earned Installation Quality Certification, visit
www.mercurymarine.com/mercruiser_warranty.
Emission Control Information Label
A tamper‑resistant Emission Control Information label is affixed in a visible location to the
engine at time of manufacture by Mercury MerCruiser. In addition to the required emissions
statement, the label lists the engine serial number, family, STD (emission standard/level),
date of manufacture (month, year), and the engine displacement. Please note that the low
emissions certification will not affect the fit, function, or performance of the engines.
Boatbuilders and dealers may not remove the label or the part it is affixed to before sale.
If modifications are necessary, contact Mercury MerCruiser about the availability of
replacement decals before proceeding.

Lanyard Stop Switch
The purpose of a lanyard stop switch is to turn off the engine when the operator moves
outside the operator's position (as in accidental ejection from the operator's position).
RUN

c
74608
a - Stop switch
b - Lanyard
Accidental ejections, such as falling overboard, are more likely to occur in:
• low‑sided sport boats
• bass boats
• high performance boats
Accidental ejections can also occur from:
• poor operating practices
• sitting on the seat or gunwale at planing speeds
• standing at planing speeds
• operating at planing speeds in shallow or obstacle infested waters
• releasing your grip on the steering wheel that is pulling in one direction
• consuming alcohol or drugs
• high speed boating maneuvers
The lanyard is a cord usually between 122 and 152 cm (4 and 5 ft) 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 at‑rest condition
as short as possible to minimize the likelihood of lanyard entanglement with nearby objects.
Its stretched‑out 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.
Activation of the lanyard stop switch will stop the engine immediately, but the 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).
c - Clips to the operator
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.

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 propulsion or steering components.
• Loss of power and directional control in heavy seas, strong current or high winds.
• Loss of control when docking.
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.
Instrumentation
The following is a brief explanation of the instrumentation typically found on some boats.
The owner/operator should be familiar with all instruments and their functions. Because of
the large variety of instrumentation and manufacturers, you should have your boat dealer
explain the particular gauges and normal readings for your boat.

Power Trim
Power trim allows the operator to adjust the sterndrive angle while underway, to provide
the ideal boat angle for varying load and water conditions. Also, the trailering feature allows
the operator to raise and lower the sterndrive unit for trailering, beaching, launching, low
speed (below 1200 RPM engine speed) and shallow water operation.
Excessive trim can cause serious injury or death at high speeds. Use caution when
trimming the sterndrive, and never trim out beyond the gimbal ring support flanges while
the boat is underway or at engine speeds above 1200 RPM.
90-899883179 OCTOBER 2007 Page 19
WARNING
!
Section 2 - Getting to Know Your Power Package
For best performance trim the sterndrive unit so that the boat bottom is at a 3‑5° angle to
the water.
Trimming sterndrive unit up/out can:
• Generally increase top speed
• Increase clearance over submerged objects or a shallow bottom
• Cause boat to accelerate and plane off slower
• In excess, cause boat porpoising (bouncing) or propeller ventilation
• Cause engine overheating if trimmed up/out to a point where any cooling water intake
holes are above the water line
3 - 5
mc79528
Trimming sterndrive unit down/in can:
• Help the boat accelerate and plane off quicker
• Generally improve the ride in choppy water
• In most cases, reduce boat speed
• If in excess, lower the bow of some boats to a point at which 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 over steering if any turn is attempted or if a significant
wave is encountered.
Single Engine Trim/Trailer
Single engine applications will have a button that can be pressed to trim the sterndrive unit
up or down.
To raise the sterndrive unit for trailering, beaching, launching, low speed (below 1200 rpm),
and shallow water operation push the trim button to raise the sterndrive unit to the full up/
out position.

Some controls also have a trailer button that trims the sterndrive to a position suitable for
trailer purposes only.
Dual Engine Trim/Trailer
NOTICE
If using external tie bars, raising or lowering the drives independently of each other can
damage the drive and steering systems. If using an external tie bar, raise and lower all
drives together as a unit.
Dual engine applications may have a single integral button to operate both sterndrive units
simultaneously or may have separate buttons for each sterndrive unit.
Some controls also have a trailer button that trims the sterndrives to a position suitable for
trailer purposes only.
Electrical System Overload Protection‑Carbureted Engines
If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. The
cause must be found and corrected before replacing the fuse or resetting the circuit
breaker.
NOTE: In an emergency, when the engine must be operated and the cause for the high
current draw cannot be located and corrected, turn off or disconnect all accessories
connected to the engine and instrumentation wiring. Reset the circuit breaker. If the breaker
remains open, the electrical overload has not been eliminated. Further checks must be
made on the electrical system. Contact your authorized dealer.
1. A circuit breaker provides protection for the engine wiring harness and the
instrumentation power lead. The circuit breaker can be tested by pushing the red
button. If the circuit breaker is functioning properly, the yellow lever will appear. Reset
the yellow lever after testing, or if tripped, by pushing the yellow lever back into the
housing.

2. A 90 amp fuse is located on the large post of the starter solenoid. This fuse is designed
to protect the engine wiring harness if an electrical overload occurs.
3. A 15 amp accessory fuse is located on the rear of the engine. This fuse protects the
accessory circuits.
