factory immediately upon sale of the new product.
• It identifies name and address of the original purchaser, product model and serial number(s), date of sale,
type of use and selling dealer’s code, name and address. The dealer also certifies that you are the original
purchaser and user of the product.
• Upon receipt of the Warranty Registration Card at the factory, you will be issued a plastic Owner Warranty
Registration Card which is your only valid registration identification. It must be presented to the servicing
dealer should warranty service be required. Warranty claims will not be accepted without presentation of this
card.
• A temporary Owner Warranty Registration Card will be presented to you when you purchase the product. It
is valid only for 30 days from date of sale while your plastic Owner Warranty Registration Card is being
processed. Should your product need service during this period, present the temporary registration card to
the dealer. He will attach it to your warranty claim form.
• Because of your selling dealer’s continuing personal interest in your satisfaction, the product should be
returned to him for warranty service.
• If your plastic card is not received within 30 days from date of new product sale, please contact your selling
dealer.

OUTSIDE THE UNITED STATES AND CANADA
• It is important that your selling dealer fills out the Warranty Registration Card completely and mails it to the
distributor or Marine Power Service Center responsible for administering the warranty registration/claim
program for your area.
• The Warranty Registration Card identifies your name and address, product model and serial number(s), date
of sale, type of use and the selling distributor’s/dealer’s code number, name and address. The
distributor/dealer also certifies that you are the original purchaser and user of the product.
• A copy of the Warranty Registration Card, designated as the “Purchaser’s Copy”, MUST be given to you
immediately after the card has been completely filled out by the selling distributor/dealer. This card represents
your factory registration identification, and should be retained by you for future use when required. Should
you ever require warranty service on this product, your dealer may ask you for the Warranty Registration Card
to verify date of purchase and to use the information on the card to prepare the warranty claim form(s).
• In some countries, the Marine Power Service Center will issue you a permanent (plastic) Warranty
Registration Card within 30 days after receiving the “Factory Copy” of the Warranty Registration Card from
your distributor/dealer. If you receive a plastic Warranty Registration Card, you may discard the “Purchaser’s
Copy” that you received from the distributor/dealer when you purchased the product. Ask your
distributor/dealer if this plastic card program applies to you.
• For further information concerning the Warranty Registration Card and its relationship to Warranty Claim
processing, refer to the “International Warranty.” Refer to “Table of Contents.”
IMPORTANT: Registration lists must be maintained by the factory and dealer in some countries by law.
It is our desire to have ALL products registered at the factory should it ever be necessary to contact you.
Make sure your dealer/distributor fills out the warranty registration card immediately and sends the
factory copy to the Marine Power International Service Center for your area.

Warranty Policies
Mercury MerCruiser One Year Limited Warranty (Gasoline Fueled Products
Only)
WHAT IS COVERED
Mercury Marine warrants its new products to be free of defects in material and workmanship during the period
described below.
DURATION OF COVERAGE
This Limited Warranty provides coverage for either one (1) year from 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. Commercial users of these products receive warranty coverage of 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
or employment related use of the product, or any use of the product which 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. Unexpired warranty coverage can be transferred from one recreational use customer to a
subsequent recreational use customer upon proper re-registration of the product. Unexpired warranty coverage
cannot be transferred either to or from a commercial use customer.
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 pre-delivery 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 obtain warranty coverage. Mercury
Marine reserves the right to make any 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 re-manufactured 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.
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. The warranty registration card is the only valid registration identification and must be presented to the dealer
at the time warranty service is requested in order to obtain coverage.

INDEX
WHAT IS NOT COVERED
This limited warranty does not cover routine maintenance items, tune ups, 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 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 which damages
the Mercury product and was 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, running the engine out of water, mounting the engine too high on 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 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 and/or replacement of boat partitions or material caused by boat design for 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, and if made, 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

Lanyard Stop Switch
2
1
74608
The purpose of a lanyard stop switch (1) 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. Some remote
control units are equipped with a lanyard stop switch. A lanyard stop switch can be installed on the dashboard
or side adjacent to the operator’s position.
The lanyard is a cord usually between 4 and 5 ft (1.22 and 1.52 m) in length when stretched out with an element
on one end made to be inserted into the switch and a snap (2) 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 minimize the 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.
IMPORTANT: 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 sport boats or bass boats, and high-performance boats. 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 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 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 (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 stopping 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 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.

CA767
Be Alert To Carbon Monoxide Poisoning
Carbon monoxide is present in the exhaust fumes of all internal combustion engines including the outboards,
sterndrives 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. Prolonged 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.
1 Example of desired air flow through the boat.

Courtesy of ABYC
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.
2 Examples 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.
3 Examples of poor ventilation while boat is moving:
A Running the boat with the trim angle of the bow too high.
B Running the boat with no forward hatches open (station wagon effect).

CD543
Wave And Wake Jumping
Operating recreational boats over waves and wakes is a natural part of boating. However, when this activity is
done with speed to force the boat hull partially or completely out of the water, certain hazards arise, particularly
when the boat re-enters the water.
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 violently veer in a new direction. Such a sharp change in direction or turn can cause occupants
to be thrown out of their seats or out of the boat.
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 nearly to a stop in an instant and can send the occupants
flying forward. The boat may also steer sharply to one side.
WARNING
Avoid serious injury or death from being thrown within or out of a boat when it lands after jumping a
wave or wake. Avoid wave or wake jumping whenever possible. Instruct all occupants that if a wake
or wave jump occurs, get low and hang on to any boat hand hold.

INDEX
CD604
Impact With Underwater Hazards
Reduce speed and proceed with caution whenever you’re driving a boat in shallow water areas or in areas where
the waters are suspected of having underwater obstacles that 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 control the boat speed. Under these conditions, boat speed should be kept to
a minimum planing speed of 15 to 25 mph (24 to 40 km/h).
Striking a floating/underwater object may result in an infinite number of situations. Some of these situations could
result in the following:
• The boat could move suddenly in a new direction. Such a sharp change in direction or turn can cause occupants to be thrown out of their seats or out of the boat.
• A rapid reduction in speed. This will cause occupants to be thrown forward, even out of the boat.
• Impact damage to the sterndrive and/or boat.
Keep in mind, one of the most important things you can do to help reduce injury or impact damage in these situations is control the boat speed. Boat speed should be kept to a minimum planing speed when driving in waters
known to have underwater obstacles.
After striking a submerged object, stop engine as soon as possible and inspect the sterndrive unit for any broken
or loose parts. If damage is present or suspected, the power package should be taken to an authorized dealer
for a thorough inspection and necessary repair.
The boat should also be checked for any hull fractures, transom fractures, water leaks.
Operating a damaged sterndrive could cause additional damage to other parts of the power package, or could
affect control of the boat. If continued running is necessary, do so at greatly reduced speeds.
WARNING
Avoid serious injury or death from loss of boat control. Continued boating with major impact damage
can result in sudden component failure with or without subsequent impacts. Have the power package
thoroughly inspected and any necessary repairs made.

Operating With Low Water Inlets In Shallow Water
A
76363
75827
CAUTION
Serious engine damage could occur by failing to follow these instructions. Sand, silt or mud could be
sucked into the water inlets restricting or shutting off the water supply to the engine.
Extreme care should be exercised when operating a boat equipped with low water inlets (A) while maneuvering
in shallow water. Also, avoid beaching the boat with the engine(s) running.
CA866
Drive Unit Impact Protection
The Power Trim hydraulic system is designed to provide impact protection for drive unit. If a submerged object
is struck while boat is moving forward, the hydraulic system will cushion the kickup of drive unit as it clears the
object, reducing damage to unit. After drive unit has cleared object, the hydraulic system allows drive unit to
return to original operating position, preventing loss of steering control and engine overspeed.
Use extreme caution when operating in shallow water or where underwater objects are known to be present.
Use extreme care to prevent striking submerged object while operating in REVERSE. No impact protection is
provided in REVERSE.
If drive unit should strike a submerged object, stop engine as soon as possible and inspect drive unit for damage.
If damage is present or suspected, boat should be taken to an Authorized Mercury MerCruiser Dealer for
thorough inspection and necessary repair. Operating a damaged drive unit could cause additional damage to
other parts of drive unit, or could affect control of boat. If continued running is necessary, do so at greatly reduced
speeds.
IMPORTANT: Impact protection system cannot be designed to ensure total protection from impact
damage under all conditions.

Safe Boating Suggestions
In order to safely enjoy the waterways, familiarize yourself with local and other governmental boating regulations
and restrictions, and consider the following suggestions.
• 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 or provincial boating law enforcement agency. Inquiries may
be made to the Boating Hotline, 1-800-368-5647 or the Boat U.S. Foundation information number
1-800-336-BOAT.
We strongly recommend that all powerboat operators attend one of these courses.
You should also review the NMMA Sources of Waterway Information booklet. It lists regional sources of safety,
cruising and local navigation and is available at no charge by writing to:
Sources of Waterway Information
National Marine Manufacturers Association
410 N. Michigan Avenue
Chicago, IL 60611 U.S.A.
• Perform safety checks and required maintenance. Follow a regular schedule and ensure that all repairs
are properly made.
• Check safety equipment on board. Here are suggestions of the types of safety equipment to carry when
boating:
1 Approved fire extinguisher(s); paddle or oar.
2 Signal devices: flashlight, rockets or flares, flag and whistle or horn.
3 Spare propeller, thrust hubs and an appropriate wrench.
4 Tools for necessary minor repairs; first aid kit and book.
5 Anchor and extra anchor line; water-proof storage containers.
6 Manual bilge pump and extra drain plugs; compass and map or chart of area.
7 Spare operating equipment; batteries, bulbs, fuses, etc.
8 Transistor radio.
9 Drinking water.
• Know signs of weather change and avoid foul weather and rough-sea boating.
• Tell someone where you are going and when you expect to return.
• Passenger boarding. Stop the engine whenever passengers are boarding, unloading or are near the back
(stern) of the boat. Just shifting the drive unit into neutral is not sufficient.
19
INDEX
• Use personal flotation devices. Federal Law requires that there be a U. S. Coast Guard approved,
wearable-type life jacket (personal flotation device), correctly sized and readily accessible for every person
on board, plus a throwable cushion or ring. We strongly advise that everyone wear a life jacket at all times
while in the boat.
• Prepare other boat operators. Instruct at least one person on board in the basics of starting and operating
the engine and boat handling in case the driver becomes disabled or falls overboard.
• Do not overload your boat. Most boats are rated and certified for maximum load (weight) capacities (refer
to your boat capacity plate). Know your boat’s operating and loading limitations. Know if your boat will float
if full of water. When in doubt, contact your dealer or the boats manufacturer.
• 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. See that all passengers have a proper seat and are in it before any boat movement.
• 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.
• Know your boating area and avoid hazardous locations.
• 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 or planing transition speed. Watch “the
other guy,” the water and your wake.
• 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 (61 m)
in front of you.
• 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.

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 drive unit 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 the drive unit 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.
CC828
High-Speed And High-Performance Boat Operation
If your boat is considered a high-speed or high-performance boat with which you are unfamiliar, we recommend
that you never operate it at its high speed capability without first requesting an initial orientation and
familiarization demonstration ride with your dealer or an operator experienced with your boat. For additional
information, obtain a copy of our Hi-Performance Boat Operation booklet (Part Number 90-849250--1) from your
dealer, distributor or Mercury Marine.
21
INDEX
CA958
Conditions Affecting Operation
Weight Distribution (Passengers And Gear) Inside The Boat
Shifting weight to rear (stern):
• Generally increases speed and engine rpm.
• At extremes, can cause boat to porpoise.
• Causes bow to bounce in choppy water.
• Increases danger of following wave splashing into boat when coming off plane.
Shifting weight to front (bow):
• Improves ease of planing.
• Improves rough water ride.
• At extremes, can cause boat to veer back and forth (bow steer).
CA959
Bottom Of Boat
To maintain maximum speed, the boat bottom should be:
• Clean, free of barnacles and marine growth.
• Free of distortion; nearly flat where it contacts the water.
• Straight and smooth, fore and aft.
Marine vegetation may accumulate when boat is docked. This growth must be removed before operation; it may
clog water inlets and cause engine to overheat.
CA9
Cavitation
Cavitation occurs when water flow cannot follow the contour of a fast-moving underwater object, such as a gear
housing or propeller. Cavitation permits the propeller to speed up, but the boat speed to reduce. Cavitation can
seriously erode the surface of the gear housing or propeller. Common causes of cavitation are:
• Weeds or other debris snagged on propeller or gear housing.
• Bent propeller blade or damaged gear housing skeg.
• Raised burrs or sharp edges on propeller or gear housing.
22
INDEX
CA10
Ventilation
Ventilation is caused by surface air or exhaust gases which are introduced around the propeller resulting in
propeller speedup and a reduction in boat speed. Excessive ventilation is annoying and usually caused by:
• Drive unit trimmed out too far.
• A missing propeller diffuser ring.
• A damaged propeller or gear housing, which allows exhaust gases to escape between propeller and gear
housing.
• Drive unit installed too high on transom.
CB822
Propeller Selection
IMPORTANT: Installed propeller must allow engine to run at its specified maximum wide open throttle
revolutions per minute (rpm). Use an accurate service tachometer to verify engine operating rpm.
It is the responsibility of the boat manufacturer and/or the selling dealer to equip the power package with the
correct propellers. Refer to Specifications for engine WOT and operating rpm range.
IMPORTANT: The engines covered in this manual are equipped with an rpm rev-limiter that is set to an
upper (or limited) rpm amount. This limit is slightly above the normal operating range of the engine and
is designed to help prevent damage from excessive engine rpm. Once the rpm drops into the
recommended operating rpm range normal engine operation resumes.
Select a propeller that will allow the engine power package to operate at or near the top end of the recommended
WOT operating rpm range with a normal load. High rpm, caused by an excessive trim angle, should not be used
in determining correct propeller selection.
If full throttle operation is below the recommended range, the propeller must be changed to prevent loss of
performance and possible engine damage. On the other hand, operating an engine above the recommended
operating rpm range will cause higher than normal wear and/or damage.
After initial propeller selection, the following common problems may require that the propeller be changed to a
lower pitch.
• Warmer weather and greater humidity cause a loss of rpm.
• Operating in a higher elevation causes a loss of rpm.
• Operating with a damaged propeller or dirty boat bottom causes a loss of rpm.
• Operating with increased load (additional passengers, pulling skiers) causes a loss or rpm.
For better acceleration, such as is needed for water skiing, use the next lower pitch propeller. Do not operate
at full throttle when using the lower pitch propeller but not pulling skiers.
23
INDEX
CA960
How Elevation And Climate Affect Performance
Elevation has a very noticeable effect on the wide open throttle power of an engine. Since air gets thinner as
elevation increases, the engine begins to starve for air. Humidity, barometric pressure and temperature do have
a noticeable effect on the density of air. Heat and humidity thin the air. This condition can become particularly
annoying when the propeller testing was done on a cool, dry day. Then later; on a hot, sultry day, the boat doesn’t
seem to have the same performance.
Although some performance can be regained by dropping to a lower pitch propeller, the basic problem still exists.
In some cases, a gear ratio change to more reduction is possible and very beneficial.
Summer conditions of high temperature, low barometric pressure and high humidity all combine to reduce the
engine power. This, in turn, is reflected in decreased boat speeds, as much as 2 or 3 mph (3 - 5 km/hr) in some
cases. Nothing will regain this speed for the boater, but the coming of cool, dry weather.
In pointing out the practical consequences of weather effects, an engine running on a hot, humid, summer day,
may encounter a loss of as much as 14% of the horsepower it would produce on a dry, brisk spring or fall day.
With the drop in available horsepower, this propeller will, in effect, become too large. Consequently, the engine
operates at less than its recommended rpm. This will result in further loss of horsepower at the propeller with
another decrease in boat speed. This secondary loss, however, can be somewhat regained by switching to a
lower-pitch propeller that allows the engine to again run at recommended rpm.
For boaters to realize optimum engine performance under changing weather conditions, it is essential that the
engine be propped to allow it to operate at or near the top end of the recommended maximum rpm range at WOT
with a normal boat load.
Not only does this allow the engine to develop full power, but equally important is the fact that the engine also
will be operating in an rpm range that discourages detonation. This, of course, enhances overall reliability and
durability of the engine.

Important Information
Operation And Maintenance
OWNER/OPERATOR RESPONSIBILITIES
It is the operator’s responsibility to perform all safety checks; to ensure that all lubrication and maintenance
instructions are complied with for safe operation and to return the unit to an Authorized Mercury MerCruiser
Dealer for a periodic checkup.
Normal maintenance service and replacement parts are the responsibility of the owner/operator and as such,
are not considered defects in workmanship or material within the terms of the warranty. Individual operating
habits and usage contribute to the need for maintenance service.
Proper maintenance and care of your power package will assure optimum performance and dependability, and
will keep your overall operating expenses at a minimum. See your Authorized Mercury MerCruiser Dealer for
service aids.
24
INDEX
CA864
DEALER RESPONSIBILITIES
In general, a dealer’s responsibilities to the customer include predelivery inspection and preparation such as:
• Make sure that the boat is properly equipped.
• Prior to delivery, make certain that the Mercury MerCruiser power package and other equipment are in proper
operating condition.
• Make all necessary adjustments for maximum efficiency.
• Familiarize the customer with the on-board equipment.
• Explain and demonstrate the operation of the power package and boat.
• At the time of delivery, the dealer should provide you with a copy of a Predelivery Inspection Checklist.
• Your selling dealer should fill out the Warranty Registration Card completely and mail it to the factory
immediately upon sale of the new product.
CA865
Freezing Temperature Operation
IMPORTANT: If boat is operated during periods of freezing temperature, precautions must be taken to
prevent freezing damage to power package. Damage caused by freezing IS NOT covered by Mercury
MerCruiser Limited Warranty.
CA867
Drain Plug and Bilge Pump
The engine compartment in your boat is a natural place for water to collect. For this reason, boats are normally
equipped with a drain plug and/or a bilge pump. It is very important to check these items on a regular basis to
ensure that the water level does not rise to come in contact with your power package. Components on your
engine will be damaged if submerged. Damage caused by submersion is not covered by the Mercury MerCruiser
Limited Warranty.
CA869
Attention Required After Submersion
• Before recovery, contact an Authorized Mercury MerCruiser Dealer.
• After recovery, immediate service by an Authorized Mercury MerCruiser Dealer is required to prevent serious
damage to power package.
25
INDEX
CA870
Trailering Boat
Boat can be trailered with drive unit in UP or DOWN position. Adequate road clearance is required between road
and gear housing skeg when trailering with drive unit in DOWN position.
If adequate road clearance is a problem, place drive unit in full trailer position and support with an optional trailer
kit which is available from your Authorized Mercury MerCruiser Dealer.
CA20
Launching And Boat Operation Care
CAUTION
During launching from a trailer, if the unloading ramp is steep or the trailer bed must be tilted, the boat
may enter the water rapidly and at a steep angle. This may force water through the exhaust system into
the cylinders. The more weight on the transom, the more likely this is to occur.
Slowing down rapidly or stopping suddenly may cause a following wave to “swamp” the transom. In
this instance, water may enter the cylinders through the exhaust system.
When backing up rapidly, the same situation may occur as stated in the preceding paragraph.
In any of these situations, water entering the engine could cause severe damage to internal parts. Refer to
Attention Required After Submersion.
CA21
Stolen Power Package
If your power package is stolen, immediately advise the local authorities and Mercury Marine of the model and
serial numbers and to whom the recovery is to be reported. This “Stolen Motor” information is placed into a file
at Mercury Marine to aid authorities and dealers in recovery of stolen motors.

CA871
Replacement Service Parts
WARNING
Electrical, ignition and fuel system components on Mercury MerCruiser gasoline power packages are
designed and manufactured to comply with U.S. Coast Guard rules and regulations to minimize risks
of fire or explosion.
Use of replacement electrical, ignition or fuel system components, which do not comply to these rules
and regulations, could result in a fire or explosion hazard and should be avoided.
When servicing the electrical, ignition and fuel systems, it is extremely important that all components
are properly installed and tightened. If not, any electrical or ignition component would permit sparks
to ignite fuel vapors from fuel system leaks, if they existed.
Marine engines are expected to operate at or near full-throttle for most of their life. They are also expected to
operate in both fresh and saltwater environments. These conditions require numerous special parts. Care should
be exercised when replacing marine engine parts as specifications are quite different from those of the standard
automotive engine.
For example, one of the most important, and probably the least suspected special replacement part, is the
cylinder head gasket. Since saltwater is highly corrosive, the steel-type automotive head gasket cannot be used.
A marine engine head gasket uses special materials to resist corrosive action.
Since marine engines must be capable of running at or near maximum rpm much of the time, special valve
springs, valve lifters, pistons, bearings, camshafts and other heavy-duty moving parts are required for long life
and peak performance.
These are but a few of the many special modifications that are required in Mercury MerCruiser marine engines
to provide long life and dependable performance.
CA872
Do-It-Yourself Maintenance Suggestions
If you are one of those persons who likes to do-it-yourself, here are some suggestions for you.
• Present-day marine equipment, such as your Mercury MerCruiser power package, are highly technical
pieces of machinery. Electronic ignition and special fuel delivery systems provide greater fuel economies, but
also are more complex for the untrained mechanic.
• Do not attempt any repairs which are not covered in this manual unless you are aware of the precautions
(Cautions and Warnings) and procedures required. Your safety is of our concern.
• If you attempt to service the product yourself, we suggest you order the service manual for that model. The
service manual outlines the correct procedures to follow. It is written for the trained mechanic, so there may
be procedures you don’t understand. Do not attempt repairs if you do not understand the procedures.
• There are special tools and equipment that are required to perform some repairs. Do not attempt these repairs
unless you have these special tools and/or equipment. You can cause damage to the product in excess of
the cost a dealer would charge you.
27
INDEX
• Also, if you partially disassemble an engine or drive assembly and are unable to repair it, the dealer’s
mechanic must reassemble the components and test to determine the problem. This will cost you more than
taking it to the dealer immediately upon having a problem. It may be a very simple adjustment to correct the
problem.
• Do not telephone the dealer, service office or the factory to attempt for them to diagnose a problem or request
the repair procedure. It is difficult for them to diagnose a problem over the telephone.
• Your Authorized Dealer is there to service your power package. They have qualified factory-trained
mechanics.
It is recommended you have the dealer do periodic maintenance checks on your power package. Have them
winterize it in the fall and service it before the boating season. This will reduce the possibility of any problems
occurring during your boating season when you want trouble-free boating pleasure.

Multiple EFI Engine Battery Precautions
Situation
Alternators: Alternators are designed to charge the battery that supplies electrical power to the engine that the
alternator is mounted on. When batteries for two different engines are connected, one alternator will supply all
of the charging current for both batteries. Normally, the other engine’s alternator will not be required to supply
any charging current.
EFI Electronic Control Module (ECM): The ECM requires a stable voltage source. During multiple engine
operation, an onboard electrical device may cause a sudden drain of voltage at the engine’s battery. The voltage
may go below the ECM’s minimum required voltage. Also, the alternator on the other engine may now start
charging. This could cause a voltage spike in the engine’s electrical system.
In either case, the ECM could shut off. When the voltage returns to the range that the ECM requires, the ECM
will reset itself. The engine will now run normally. This ECM shut down usually happens so fast that the engine
just appears to have an ignition miss.
Recommendations
Batteries: Boats with multi-engine EFI power packages require each engine be connected to its own battery.
This ensures that the engine’s Electronic Control Module (ECM) has a stable voltage source.
Battery Switches: Battery switches should always be positioned so each engine is running off its own battery.
DO NOT operate engines with switches in BOTH or ALL position. In an emergency, another engine’s battery
can be used to start an engine with a dead battery.
Battery Isolators: Isolators can be used to charge an auxiliary battery used for powering accessories in the
boat. They should not be used to charge the battery of another engine in the boat unless the type of isolator is
specifically designed for this purpose.
Generators: The generator’s battery should be considered another engine’s battery.

Diagnosing EFI Problems
Your Authorized Mercury MerCruiser Dealer has the proper service tools for diagnosing problems on Electronic
Fuel Injection (EFI) Systems. The Electronic Control Module (ECM) on these engines has the ability to detect
some problems with the system when they occur, and store this information in the ECM’s memory. This data can
then be read later by a service technician using a special diagnostic tool.
CA413
20-Hour Break-In Period
IMPORTANT: The first 20 hours of operation is the engine break-in period. Correct break-in is essential
to obtain minimum oil consumption and maximum engine performance. During this break-in period, the
following rules must be observed:
• Do not operate below 1500 rpm for extended periods of time for first 10 hours. Shift into gear as soon as
possible after starting and advance throttle above 1500 rpm if conditions permit safe operation.
• Do not operate at one speed consistently for extended periods.
• Do not exceed 3/4 throttle during first 10 hours. During next 10 hours, occasional operation at full throttle is
permissible (5 minutes at a time maximum).
• Avoid full throttle acceleration from IDLE speed.
• Do not operate at full throttle until engine reaches normal operating temperature.
• Frequently check crankcase oil level. Add oil if needed. It is normal for oil consumption to be high during
break-in period.
CA874
After Break-In Period
To help extend the life of your Mercury MerCruiser power package, the following recommendations should be
considered;
• Use a propeller that allows the engine to operate at or near the top of the maximum rpm range (See
Specifications section) when at full throttle with a normal boat load.
• Operation at 3/4 throttle setting or lower is recommended. Refrain from prolonged operation at maximum (full
throttle) rpm.
CA875
End of First Season Checkup
At the end of the first season of operation, an Authorized Mercury MerCruiser Dealer should be contacted to
discuss and/or perform various scheduled maintenance items. If you are in an area where the product is
operated continuously (year-round operation), you should contact your dealer at the end of the first 100 hours
of operation, or once yearly, whichever occurs first.

Power Trim
3 - 5°
1
Power Trim allows the operator to adjust the drive angle, while underway, to provide the ideal boat angle for
varying load and water conditions. Also, the Power Trim system Trailering feature allows the operator to raise
and lower the drive unit for trailering, beaching, launching and low speed (below 1200 rpm engine speed),
shallow water operation.
CAUTION
Use extreme caution when operating with drive unit raised. Severe damage to the drive unit may result
if unit is raised beyond the gimbal ring support flanges at engine speeds above 1200 rpm.
1 In most cases, best overall performance is obtained with the drive unit adjusted so the boat bottom will run
at a 3° to 5° angle to the water.
Trimming Drive 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.
Trimming Drive 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.

CB804
SINGLE ENGINE TRIM/TRAILER
Single engine applications will have a button that can be pressed to trim the drive unit up or down.
To raise the drive unit for trailering, beaching, launching and low speed, (below 1200 rpm) shallow water operation push the trim button to raise the drive unit to the full UP / OUT position.
Some controls also have a trailer button that trims the drive to a position suitable only for trailer purposes.
DUAL ENGINE TRIM/TRAILER
CAUTION
When lowering or raising sterndrives equipped with a dual engine tie bar kit, the sterndrives must be
raised or lowered evenly to prevent the tie bar from becoming twisted. Failure to raise or lower sterndrives evenly may result in tie bar or sterndrive damage.
Dual engine applications may have a single integral button to operate both drive units simultaneously or may
have separate buttons for each drive unit.
Some controls also have a trailer button that trims the drives to a position suitable for trailer purposes only.

Starting, Shifting And Stopping
WARNING
Before starting engine, operate bilge blower for at least five minutes to remove any explosive fumes
from engine compartment. If boat is not equipped with a bilge blower, open engine hatch and leave
open while starting engine.
CAUTION
It is good practice to ventilate the engine compartment prior to servicing any engine components to
remove any fuel vapors which may cause difficulty breathing or be an irritant.
IMPORTANT: Observe the following:
• Do not start engine without water being supplied to seawater pickup pump (to prevent pump or
engine damage).
• Do not operate starter motor continuously for more than 30 seconds.
• Never shift drive unit unless engine is at idle rpm.
35
INDEX
Perform the following as appropriate:
1 Check all items listed in Operation Chart.
2 Perform any other necessary checks, as indicated by your dealer, or specified in your boat owner’s manual.
3 Place drive unit in full DOWN/IN position.
4 Place control handle in NEUTRAL.
5 Position throttle setting as follows:
A COLD ENGINE - Leave in NEUTRAL/IDLE speed position.
B WARM ENGINE - Leave in NEUTRAL/IDLE speed position.
C FLOODED ENGINE - Turn ignition switch to ON position. Push the throttle only button and place the throttle
lever in the 50% position. Attempt to start engine. As soon as engine starts, return throttle to the IDLE position.
6 Turn ignition key to the START position. Release key when engine starts and allow switch to return to RUN
position.
7 Check oil pressure gauge immediately after engine starts. If oil pressure is not within specified range (Refer
to Specifications), stop engine immediately and determine cause.
8 If engine is cold, operate engine for 1 or 2 minutes at fast idle (1000-1500 rpm).
9 After engine has warmed up, check water temperature gauge to ensure that engine temperature is not
abnormally high. If it is, stop engine immediately and determine cause.
10 Be sure charging system is functioning correctly.
11 Observe power package for fuel, oil, water and exhaust leaks.
12 To shift drive unit, return control/throttle lever to NEUTRAL. Move control/shift lever with a firm, quick motion
forward to shift into FORWARD gear, or backward to shift into REVERSE. After shifting drive unit, advance
throttle to desired setting.
13 Move control/shift lever to NEUTRAL and allow engine to drop to IDLE speed. If engine has been operated
at high speed for a long period of time, allow engine to cool by operating at IDLE speed for 3 to 5 minutes.
14 Turn ignition key to OFF.
36
INDEX
CC829
CAUTION
To avoid possible ingestion of water that can damage engine components:
• Do not turn the ignition key off when the engine is running above idle speed.
• Do not use the lanyard stop switch to shut off the engine above idle speed.
• When coming off plane, if a large following wave may roll over the boat’s transom, apply a short,
light burst of throttle to minimize the wave action against the stern of the boat.
• Do not come off plane quickly, shift into reverse and shut off engine.
CB575
IMPORTANT: Avoid stopping engine if the drive unit is in gear. If engine does stop with drive unit in gear,
refer to the following procedure:
15 Push and pull repeatedly on remote control handle until handle returns to the neutral detent position. This
may take several tries if the power package was operating above idle rpm when the engine stopped.
16 After handle returns to the neutral detent position, resume normal starting procedures.
CB843
Engine Guardian
IMPORTANT: Boat speed could be reduced to idle and may not respond to throttle.
Engine Guardian Strategy is designed to help reduce the potential for engine damage by reducing engine power
when a potential problem is sensed. Engine Guardian monitors:
• Oil Pressure
• Coolant Temperature
• Sea Pump Pressure
• Exhaust Manifold Temperature
For example, if one exhaust manifold’s water cooling passages become partially blocked, Engine Guardian will
reduce the power level of the engine to bring the temperature on that manifold back into the normal operating
temperature range. If the debris passes through and full water flow is restored, engine power levels are restored
back to normal. In other words, Engine Guardian is a looped feedback or smart system.

Fuel Recommendations
CAUTION
Use of improper gasoline can damage your engine seriously. Engine damage resulting from use of
improper gasoline is considered misuse of engine, and damage caused thereby will not be covered
under the limited warranty.
FUEL RATINGS
Mercury MerCruiser engines will operate satisfactorily when using a major brand of unleaded gasoline as
follows:
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.
CA878
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
is 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 also.
These Reformulated Gasolines are acceptable for use in your Mercury MerCruiser engine.
CA879
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.
The fuel system components on your Mercury MerCruiser engine will withstand up to 10% alcohol content in
the gasoline. We do not know what percentage your boat’s fuel system will withstand. Contact your boat
manufacturer for specific recommendations on the boats fuel system components (fuel tanks, fuel lines, and
fittings). Be aware that gasolines containing alcohol may cause increased:
• Corrosion of metal parts.
• Deterioration of rubber or plastic parts.
• Fuel permeation through rubber fuel lines.
• Starting and operating difficulties.
WARNING
FIRE AND EXPLOSION HAZARD: Fuel leakage from any part of fuel system can be a fire and explosion
hazard which can cause serious bodily injury or death. Careful periodic inspection of entire fuel
system is mandatory, particularly after storage. All fuel components including fuel tanks, whether
plastic metal or fiberglass, fuel lines, fittings, fuel filters and carburetors/fuel injection components
should be inspected for leakage, softening, hardening, swelling or corrosion. Any sign of leakage or
deterioration requires replacement before further engine operation.
39
INDEX
Because of possible adverse effects of alcohol in gasoline, it is recommended that only alcohol-free 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 MerCruiser 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 alcohol-blend 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.
CC540
Seacock Size Recommendation
Seacock used must have an internal cross-sectional area equal to or greater than hose to prevent restricting
waterflow. Install valve in an area where it will be easily accessible and supported adequately to prevent hose
fatigue. A 1-1/4 in. (32 mm) brass ball or gate valve is suggested.
CA693
Crankcase Oil
To help obtain optimum engine performance and to provide maximum protection, we strongly recommend the
use of Quicksilver 4-Cycle 25W-40 Marine Engine Oil. This oil is a special blend of 25-weight and 40-weight oils
for marine engines. If not available, a good grade, straight weight, detergent automotive oil of correct viscosity,
with an API classification of SH,CF/CF-2, may be used.
In those areas where Quicksilver 4-Cycle 25W-40 Marine Engine Oil or a recommended straight weight oil are
not available, a multi-viscosity 20W-40 or, as a second but less preferable choice, 20W-50, with API service
ratings of SH, CF/CF-2 may be used.
IMPORTANT: The use of non-detergent oils, multi-viscosity oils (other than Quicksilver 25W-40 or a
good quality 20W-40 or 20W-50), synthetic oils, low quality oils or oils that contain solid additives are
specifically not recommended.
The chart below is a guide to crankcase oil selection. The oil filter should always be changed when changing
engine oil.

Corrosion And Corrosion Protection
Whenever two or more dissimilar metals (like those found on the sterndrive) are submerged in a conductive
solution, such as saltwater, polluted water, or water with a high mineral content, a chemical reaction takes place
causing electrical current to flow between metals. The electrical current flow causes the metal that is most
chemically active, or anodic, to erode. This is known as galvanic corrosion and, if not controlled, it will in time
cause the need for replacement of power package components exposed to water.
IMPORTANT: Replace sacrificial anodes if eroded 50% or more.
1 Universal Anodic Plate - serves as a sacrificial anode.
2 Anodic Plate - serves as a sacrificial anode.
3 MerCathode System - should be tested to ensure adequate output.
Test should be made where boat is moored, using Quicksilver Reference Electrode and Test Meter. Contact your
Authorized Mercury MerCruiser Dealer to arrange for this test.
4 Anode Kit (if equipped) - Mounted to boat transom. Acts as a sacrificial anode.
CA440
5 Trim Cylinder Anodes - are mounted on each trim cylinder.
CB764
6 Bearing Carrier Anode (Bravo One) - is located in front of the propeller, between the front side of the
propeller and the gear housing. Refer to Propeller section in this manual for propeller removal and
installation.

In addition to the corrosion protection devices, the following steps should be taken to inhibit corrosion:
IMPORTANT: Corrosion damage that results from the improper application of anti-fouling paint will not
be covered by the limited warranty.
1 Painting Boat Hull or Boat Transom: Anti-fouling paint may be applied to boat hull and boat transom but
you must observe the following precautions:
IMPORTANT: DO NOT paint anodes or MerCathode System reference electrode and anode, as this will
render them ineffective as galvanic corrosion inhibitors.
IMPORTANT: If anti-fouling protection is required for boat hull or boat transom, copper or tin base
paints, if not prohibited by law, can be used. If using copper or tin based anti-fouling paints, observe
the following:
2 Avoid any electrical interconnection between the Mercury MerCruiser Product, Anodic Blocks, or
MerCathode System and the paint by allowing a minimum of 1-1/2 in. (40 mm) UNPAINTED area on
transom of the boat around these items.
3 Painting Drive Unit or Transom Assembly: Drive unit and transom assembly should be painted with a
good quality marine paint or an anti-fouling paint that DOES NOT contain copper, tin, or any other material
that could conduct electrical current. Do not paint drain holes, anodes, MerCathode system, and items
specified by boat manufacturer.
4 Spray power package components on inside of boat annually with Quicksilver Corrosion Guard to protect
finish from dulling and corrosion. External power package components may also be sprayed.
5 All lubrication points, especially steering system, shift and throttle linkages, should be kept well lubricated.
6 Flush cooling system periodically, preferably after each use.

Miscellaneous Maintenance
Battery
All lead acid batteries discharge when not in use. Recharge every 30 to 45 days, or when specific gravity drops
below battery manufacturer’s specifications.
Refer to specific instructions and warnings accompanying your battery. If this information is not available,
observe the following precautions when handling a battery.
WARNING
Avoid serious injury from gasoline fire or explosion. Do not use jumper cables and a booster battery
to start engine. Do not recharge a weak battery in the boat. Remove battery and recharge in a ventilated
area away from fuel vapors, sparks or flames.
WARNING
Batteries contain acid which can cause severe burns-Avoid contact with skin, eyes and clothing. Batteries also produce hydrogen and oxygen gases when being charged. This explosive gas escapes fill/
vent cell caps and may form an explosive atmosphere around the battery for several hours after it has
been charged. Sparks or flames can ignite the gas and cause an explosion which may shatter the battery and could cause blindness or other serious injury.
Safety glasses and rubber gloves are recommended when handling batteries or filling with electrolyte.
Hydrogen gases that escape from the battery during charging are explosive. When charging batteries,
be sure battery compartment or area where batteries are located, is well-vented. Battery electrolyte is
a corrosive acid and should be handled with care. If electrolyte is spilled or splashed on any part of
the body, immediately flush the exposed area with liberal amounts of water and obtain medical aid as
soon as possible.
CA962
Inspection And Maintenance
Inspect power package often, and at regular intervals, to help maintain its top operating performance and correct
potential problems before they occur. The entire power package should be checked carefully, including all
accessible engine parts.
Check for loose, damaged or missing parts, hoses and clamps; tighten or replace as required.
Check plug leads and electrical leads for damage.
Remove and inspect propeller. If badly nicked, bent or cracked, see your Authorized Mercury MerCruiser Dealer.
Repair nicks and corrosion damage on power package exterior finish. Use Quicksilver spray paints - see your
Authorized Mercury MerCruiser Dealer.
