Warranty Policies
Recreational Use Diesel Limited Warranty
WHAT IS COVERED
Cummins MerCruiser Diesel 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 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 use of the product voids the warranty.
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 Cummins MerCruiser Diesel to distribute the product in the country in which
the sale occurred, and then only after the Cummins MerCruiser Diesel 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 re-registered) may void the warranty at the sole
discretion of Cummins MerCruiser Diesel. Routine maintenance outlined in the Operation,
Maintenance, and Warranty Manual must be timely performed in order to obtain warranty
coverage. Cummins MerCruiser Diesel reserves the right to make any warranty coverage
contingent upon proof of proper maintenance.
WHAT CUMMINS MERCRUISER DIESEL WILL DO
Cummins MerCruiser Diesel’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 Cummins
MerCruiser Diesel product. Mercury reserves the right to improve or modify products from
time to time without assuming an obligation to modify products previously manufactured.

Page 13
SECTION 1SECTION 1
HOW TO OBTAIN WARRANTY COVERAGE
The customer must provide Cummins MerCruiser Diesel 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 Cummins MerCruiser Diesel dealer /
distributor authorized to service the product. If purchaser cannot deliver the product to such
a dealer, written notice must be given to Cummins MerCruiser Diesel. 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 Cummins MerCruiser
Diesel, ship the product or parts of the product directly to Cummins MerCruiser Diesel. 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.
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 operate at the recommended Engine Rated rpm,
operation of the product in a manner inconsistent with the recommended operation / duty
cycle section of the Operation, Maintenance, And Warranty Manual, neglect, accident,

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.
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 Cummins MerCruiser Diesel authorized dealers, has been
given authority by Cummins MerCruiser Diesel 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 Cummins MerCruiser Diesel.

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

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).

b-Lanyard
c-Clips to the operator
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
a
•operating at planing speeds in shallow or obstacle infested waters
•releasing your grip on the steering wheel that is pulling in 1 direction
•consuming alcohol or drugs
•high speed boating maneuvers
Some remote control units are equipped with a lanyard stop switch, if your remote control
is not equipped with a lanyard stop switch one can be installed on the dashboard or side
adjacent to the operator’s position. The lanyard is a cord usually 1.2 - 1.5 m (4 - 5 ft) long
when stretched out with an element on 1 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 it as short as
possible to minimize the likelihood of entanglement with nearby objects. It stretches to
minimize the likelihood of accidental activation should the operator choose to move around
in an area close to the normal operator’s position. To shorten the lanyard, wrap it around
the operator’s wrist or leg, or tie a knot in the lanyard.

Page 19
SECTION 2
GETTING TO KNOW YOUR POWER PACKAGE
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).
WARNING
Avoid contact with the boat hull and propeller from accidental ejection. Personal
injury or death could occur. Always properly connect both ends of the lanyard stop
switch.
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.
WARNING
Avoid abrupt deceleration of the boat from lanyard stop switch activation. Boat
damage and personal injury or death could occur. NEVER leave the operator’s
station with the engine operating and in gear.

Electrical System Overload Protection
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 Cummins MerCruiser Diesel dealer
/ distributor.

In order to safely enjoy the waterways, familiarize yourself with local and all other
governmental boating regulations and restrictions and also consider the following
suggestions.
•Know and obey all nautical rules and laws of the waterways.
Cummins MerCruiser Diesel strongly recommends that all powerboat operators complete
a boating safety course. Courses are offered in the U.S.A. by: The U.S. Coast Guard
Auxiliary, The Power Squadron, The Red Cross and your state or provincial boating law
enforcement agency. Inquiries may be made to the Boating Hotline at 1-800-368-5647 or

ON THE WATER
•Watch for 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. Shifting the drive unit into neutral
is not sufficient.
•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 1 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 authorized Cummins MerCruiser Diesel dealer / distributor or the boat
manufacturer.
•Ensure that everyone in the boat is properly seated. Do not allow anyone to sit or
ride on any part of the boat that was not intended for such use. This includes the
backs of seats, gunwales, transom, bow, decks, raised fishing seats and 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. Ensure 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.
CMD-4081877 / 90-865861040 MARCH 2004Page 23
Page 32
ON THE WATER
•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 out for others, 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 40 km/h (25 mph) will overtake a fallen skier who
was 61 m (200 ft) in front of you in 5 seconds.
•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 to 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.

Be Alert To Carbon Monoxide Poisoning
SECTION 3
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 prolonged exposure to carbon monoxide. Carbon monoxide poisoning can
lead to unconsciousness, brain damage or death. Ensure that the boat, while at rest
or underway, is well ventilated.

Freezing Temperature And Cold Weather 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 Cummins MerCruiser Diesel Limited Warranty.
CAUTION
Seawater (raw water) section of cooling system MUST BE COMPLETELY drained for
winter storage or immediately after cold weather use, if the possibility of freezing
temperatures exist. Failure to comply may result in trapped water causing freeze
and/or corrosion damage to engine.
In order to operate the engine in temperatures of 0 degrees C (32 degrees F) or lower,
observe the following instructions:
• At the end of each daily operation, COMPLETELY drain seawater section of cooling
system to protect against damage by freezing.
• At the end of each daily operation, drain water from water separator, if equipped. Fill fuel
tank at end of daily operation to prevent condensation.
• Use required permanent-type antifreeze solution to protect components against
damage by freezing.

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 come into
contact with your power package. Components on your engine will be damaged if
submerged. Damage caused by submersion is not covered by the Cummins MerCruiser

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) in NEUTRAL/IDLE, 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
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 gear case or any solid device rigidly attached to a moving boat or
gear case.

WARNING
Shift into the NEUTRAL/IDLE position and shut off the engine before allowing people to
swim or be in the water near your boat.

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

Passenger Safety Message - Pontoon And Deck Boats
WARNING
Avoid serious injury or death from falling over the front end of a pontoon or deck
boat and coming in contact with the boat hull or propeller. Stay back from the front
end of the deck and remain seated while the boat is in motion.
Whenever the boat is in motion, observe the location of all the 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 the result of 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 boat. Falling over the front of the boat between the two pontoons will position
them to come into contact with the drive unit.
1. Boats having an open front deck:
a. No one should ever be on the deck in front of the fence while the boat is in motion. Keep
all passengers behind the front fence or enclosure.
b. Persons on the front deck could easily be thrown overboard or persons dangling
their feet over the front edge could get their legs caught by a wave and pulled into
the water.
SECTION 3

IncorrectCorrect
2. Boats with front-mounted, raised pedestal fishing seats:
a. These 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.
b. Any unexpected sudden reduction in boat speed could result in the elevated
passenger falling over the front of the boat.

Wave And Wake Jumping
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
a boat hand hold.
Operating recreational boats over waves and wakes is a natural part of boating. However,
when this activity is done with enough 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
cases 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.
ON THE WATER
mc79675
WARNING
There is another less common hazardous result from allowing your boat to launch off of 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 veer sharply to one side.

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 underwater drive components, rudder 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 24 to 40 km/h (15 to 25 MPH).
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.
SECTION 3
mc79680
• A rapid reduction in speed. This will cause occupants to be thrown forward, even out of
the boat.
• Impact damage to the underwater drive components, rudder 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 drive
system 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 with damaged underwater drive components, rudder or boat bottom 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.

Conditions Affecting Operation
Weight Distribution (Passengers And Gear) Inside The Boat
Shifting weight to rear (stern):
•Generally increases speed and engine rpm
•Causes bow to bounce in choppy water
•Increases danger of following wave splashing into the boat when coming off plane
•At extremes, can cause the boat to porpoise
Shifting weight to front (bow):
•Improves ease of planing
•Improves rough water ride
•At extremes, can cause the boat to veer back and forth (bow steer)
0037
Bottom Of Boat
ON THE WATER
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 the boat is docked. This growth must be removed
before operation; it may clog the water inlets and cause the engine to overheat.
0039 w changes to fit these diesel engines
Elevation And Climate
NOTE: Engines equipped with an Electronic Control Module (ECM) reduce the effects of
changes in elevation and climate by automatically adjusting fuel flow for weather conditions
and elevation. ECM controlled engines however, do not compensate for increased loading
or hull conditions.
Elevation and climate changes will affect the performance of your power package. Loss of
performance can be caused by:
•Higher elevations
•Higher temperatures
•Low barometric pressures
•High humidity
For you to have optimum engine performance under changing weather conditions, it is
essential that the engine be propped to allow the engine to operate at or near the top end
of the Rated Engine rpm with a normal boat load during your normal boating weather
conditions.
In most cases, performance can be regained by changing to a lower pitch propeller.

Propeller Selection
The installed propeller must allow the engine to run at the Rated Engine rpm at WOT
to avoid engine damage. Using a propeller that causes the engine to operate below
the Rated Engine rpm can cause piston and/or valve damage (even if the engine is
not operated at WOT). Conversely, using a propeller that allows engine to operate
above the specified Rated Engine rpm can increase fuel consumption and wear and
will not allow engine to produce its rated horsepower.
It is the responsibility of the boat manufacturer and/or the selling dealer to equip the power
package with the correct propellers.
IMPORTANT: The engines covered in this manual are equipped with an ECM that
limits engine rpm. Be sure that propeller being used does not allow engine to run
against the limiter, as a significant loss in performance will result.
NOTE: Use an accurate service tachometer to verify rpm.
Select a propeller that will allow the engine power package to operate at the Rated Engine
rpm with a full load.
If full throttle operation is below the Engine Rated rpm, the propeller must be changed to
prevent loss of performance and possible engine damage. On the other hand, operating an
engine above the Rated Engine rpm will cause higher than normal wear and/or damage.
SECTION 3
CAUTION
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 an rpm loss (not as significant on these
models).
• Operating in a higher elevation causes an rpm loss (not as significant on these models).
• Operating with a damaged propeller or dirty boat bottom causes an rpm loss.
• Operating with increased load (additional passengers, pulling skiers).

break-in procedure allows the proper seating of the pistons and rings, which greatly reduces
the likelihood of problems.
IMPORTANT: It is recommended that the boat not be accelerated hard until this
procedure has been completed.
IMPORTANT: Never operate the starter motor longer than 15 seconds at a time, to
avoid overheating the starter motor. If engine does not start, wait 1 minute to allow
the starter motor to cool; then, repeat starting procedure.
1. Refer to appropriate Starting, Shifting and Stopping section and start the engine.
Operate the engine at a fast idle until it has reached normal operating temperature.
2. Operate the engine in gear for 3 minutes at each of the following rpms: 1200 rpm, 2400
rpm and 3000 rpm.
3. Operate the engine in gear for 3 minutes at each of the following rpms: 1500 rpm, 2800
rpm and 3400 rpm.

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 the first 10 hours.
Shift into gear as soon as possible after starting and advance the 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 the first 10 hours. During the 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 the engine reaches normal operating temperature.
•Frequently check engine oil level. Add oil as needed. It is normal for oil consumption
to be high during the break-in period.
•AT END OF 20-HOUR break-in period, remove break-in oil and replace oil filter. Fill
the engine with the correct grade and viscosity oil.

After Break-In Period
To help extend the life of your Cummins MerCruiser Diesel power package, the following
recommendations should be considered:
•Use a propeller that allows the engine to operate at the Rated Engine rpm at WOT
when at full throttle with a full boat load. Refer to Specifications and Maintenance.
•Operation at 3/4 throttle setting or lower is recommended. Refrain from prolonged
operation at WOT rpm.

End of First Season Checkup
At the end of the first season of operation, contact an authorized Cumins MerCruiser Diesel
dealer / distributor to discuss and/or perform scheduled maintenance items. If you are in an
area where the product is operated continuously, year-round, you should contact your
dealer at the end of the first 100 hours of operation or once yearly, whichever occurs first.
Electrical system components on this engine are not external ignition protected.
DO NOT STORE OR UTILIZE GASOLINE ON BOATS EQUIPPED WITH THESE
ENGINES, UNLESS PROVISIONS HAVE BEEN MADE TO EXCLUDE GASOLINE
VAPORS FROM ENGINE COMPARTMENT (REF: 33 CFR). Failure to comply could
result in fire, explosion and/or severe personal injury.
FIRE HAZARD: Fuel leakage from any part of the fuel system can be a fire 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, primers, fittings, and fuel
filters should be inspected for leakage, soften, hardening, swelling or corrosion.
Any sign of leakage or deterioration requires replacement before further engine
operation.
SECTION 4
WARNING
WARNING
WARNING
Under no circumstances should gasoline, gasohol and/or alcohol be mixed with
diesel fuel for any reason. This mixture of gasoline, gasohol and/or alcohol with
diesel fuel is highly flammable and produces a significant risk to the user.
IMPORTANT: Use of improper or water contaminated diesel fuel can damage your engine seriously. Use of improper fuel is considered misuse of engine, and damage
caused thereby will not be covered by warranty.
Grade 2-D diesel fuel is required, meeting ASTM Standards D975 (or fuel rated Diesel DIN
51601), and having a minimum cetane rating of 45.
The Cetane number is a measure of the ignition quality of diesel fuel. Increasing the cetane
number will not improve overall engine performance, but it may be necessary to raise the
cetane rating for low temperature, or high altitude use. A lower cetane number could cause
hard starting and slower warm-up, and could increase engine noise and exhaust emissions.
NOTE: If your engine suddenly becomes noisy after a fuel fill, you possibly received
substandard fuel with a low cetane rating.
Sulphur content of the above fuel is rated at 0.50% by weight, maximum (ASTM). Limits may
vary in countries outside of the United States.
On intermittent use engines, high sulphur content diesel fuel will greatly increase:
•Corrosion on metal parts.
•Deterioration of elastomer and plastic parts.
•Corrosion and extensive damage, and excessive wear of internal engine parts, par-
ticularly bearings.
•Starting and operating difficulties.

Diesel Fuel In Cold Weather
Unaltered diesel fuels thicken and gel in cold temperatures, unless treated. Virtually all
diesel fuels are climatized to allow their use in the particular region for that time of the year.
If it becomes necessary to further treat diesel fuel, it is the owner/operator’s responsibility
to add a commercial standard brand anti-gel diesel fuel additive, following that product’s
directions.
CE528
AntiFreeze/Coolant
Alcohol or Methanol base antifreeze or plain water are not recommended for use in
closed cooling section of cooling system at any time.
Because diesel engines are high compression engines and related higher engine operating
temperatures are created, the closed cooling system and engine, including related cooling
passages must remain as clean as possible to provide adequate engine cooling. This can
only be assured by using the proper antifreeze, water, additives and inhibitors. It is
recommended that the closed cooled section of the cooling system be filled with a low
silicate formula of ethylene glycol antifreeze in solution with deionized water. A low silicate
formula prevents antifreeze separation which causes a silicate gelatin to form. This gelatin
will block engine and heat exchanger passages causing engine overheating.
SPECIFICATIONS
CAUTION
The coolant, if not premixed, should be mixed before being added to the closed cooling
system using a proper antifreeze together with deionized water. Common tap water or
softened water contains unwanted minerals which can leave large deposits in the system
that restrict the cooling system efficiency. In addition, additives and inhibitors introduced into
acceptable coolant solutions will form a protective film on internal passages and provide
protection against internal cooling system erosion.
CMD-4081877 / 90-865861040 MARCH 2004Page 43
Page 52
SPECIFICATIONS
SECTION 4
The closed cooling section should be kept filled year-round with an acceptable
antifreeze/coolant solution. Do not drain closed cooled section for storage, as this will
promote rusting of internal surfaces. If engine will be exposed to freezing temperatures,
ensure that the closed cooled section is filled with a properly mixed antifreeze/coolant
solution, to protect engine and closed cooling system to lowest temperature to which they
will be exposed.
NOTE: A 50/50 antifreeze/coolant solution should be used except when operating where
seawater temperatures are greater than 32 degrees C (90 degrees F), then a 25 / 75
(antifreeze / water) solution can be used for improved cooling performance.
IMPORTANT: The antifreeze/coolant used in these marine engines must be a low
silicate ethylene glycol, containing special additives, and deionized, purified water.
Using other types of engine coolant may cause fouling of the heat exchangers, and
overheating of the engine. Do not combine different types of coolants without
knowing that they are compatible. Refer to the coolant manufacturer’s instructions.
Some acceptable types of antifreeze/coolants are listed in the following table. Refer to
Maintenance Schedules for respective change intervals.

Do-It-Yourself Maintenance Suggestions
Present-day marine equipment, such as your Cummins MerCruiser Diesel power package,
are highly technical pieces of machinery. Special fuel delivery systems provide greater fuel
economies, but also are more complex for the untrained mechanic.
If you are one of those persons who likes to do-it-yourself, here are some suggestions for
you.
•Do not attempt any repairs unless you are aware of the Cautions, Warnings and
procedures required. Your safety is 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.
•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.
SECTION 5
00000 was CE529
Inspection
•Do not telephone the dealer, service office or the factory to attempt for them to diagnose
a problem or to request the repair procedure. It is difficult for them to diagnose a problem
over the telephone.
Your local dealer / distributor of Cummins MerCruiser Diesel products 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.
Inspect your 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
necessary.
Check electrical connections and leads for damage.
Remove and inspect the propeller. If badly nicked, bent or cracked, contact your authorized
Cummins MerCruiser Diesel dealer / distributor.
Repair nicks and corrosion damage on power package exterior finish. Contact your
authorized Cummins MerCruiser Diesel dealer / distributor.

Water Separating Fuel Filter
Be careful when draining water separating fuel filter. Diesel fuel is flammable. Be
sure ignition key is OFF. Do not allow fuel to contact any hot surfaces which may
cause it to ignite. Do not allow sources of open flame in the area. Wipe up any spilled
fuel immediately. Dispose of fuel soaked rags, paper, etc. in an appropriate air tight,
fire retardant container. Fuel soaked items may spontaneously ignite and result in
a fire hazard which could cause serious bodily injury or death.
Any water entering the fuel injection system will disable the system. Check for water in water separating fuel filter before starting, daily.
If water should enter the fuel injection system, take unit to an authorized Cummins
MerCruiser Diesel dealer / distributor IMMEDIATELY, so that corrosion and rusting
of the injectors and other components can be avoided.

Corrosion Protection
Whenever two or more dissimilar metals 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. Refer to the Marine Corrosion Protection Guide
(90-88181301).

Multiple Electronic Control Engine Battery Precautions
SITUATION
Alternators: Alternators are designed to charge a single battery that supplies the electrical
power to the individual engine that the alternator is mounted on. Connect only one battery
to one alternator. Do not connect two batteries to the same alternator unless a battery
isolator is used.
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 Electronic Control 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.
MAINTENANCE
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. Isolators 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 in the same manner as another
engine’s battery.
Cold Weather (Freezing Temperature), Seasonal, And
Extended Storage
IMPORTANT: Cummins MerCruiser Diesel strongly recommends that this service
should be performed by an authorized Cummins MerCruiser Diesel dealer /
distributor. Damage caused by freezing IS NOT
Diesel Limited Warranty.
CAUTION
Avoid cooling system and engine damage. Water trapped in the seawater section
of the cooling system can cause corrosion damage, can freeze causing freeze
damage, or may result in both types of damage. Ensure that the seawater section
of the cooling system is drained immediately after operation or before any length
of storage in cold weather if the possibility of freezing temperatures exists.
Consider a boat is in storage whenever it is not in operation. The amount of time that the
power package is not operated may be for a brief period, such as during a day, overnight,
for a season, or for an extended period of time. Certain precautions and procedures must
be observed to protect the power package from freeze damage, corrosion damage, or both
types of damage during storage.
covered by the Cummins MerCruiser
SECTION 6
Freeze damage can be caused when water trapped in the seawater cooling system is
frozen. For example, after operating the boat, exposure to freezing temperatures for even
a brief period of time could result in freeze damage.
Corrosion damage is the result of saltwater, polluted water, or water with a high mineral
content trapped in the seawater cooling system. Saltwater should not stay in an engine’s
cooling system for even a brief storage time; drain and flush the seawater cooling system
after each outing.
Cold weather operation refers to operating the boat whenever the possibility of freezing
temperatures exists. Likewise, cold weather (freezing temperature) storage refers to
whenever the boat is not being operated and the possibility of freezing temperatures exists.
In such cases, the seawater section of the cooling system must be completely drained
immediately after operation.
Seasonal storage refers to when the boat is not being operated for 1 month or more. The
length of time varies depending on the geographic location of the boat in storage. Seasonal
storage precautions and procedures include all of the steps for cold weather (freezing
temperature) storage and some additional steps that must be taken when storage will last
longer than the short time of cold weather (freezing temperature) storage.
Extended storage means storage for a period of time that may last for several seasons or
longer. Extended storage precautions and procedures include all of the steps for cold
weather (freezing temperature) storage and seasonal storage plus some additional steps.
Refer to the specific procedures in this Section 6 related to the conditions and the length
of storage for your application.

Seasonal Storage Instructions
1. Read all precautions and perform all procedures found in Preparing Your Power
Package For Seasonal or Extended Storage.
2. Read all precautions and perform all procedures found in Section 5 - Draining The
Seawater System and drain the seawater section of the cooling system.
IMPORTANT: Cummins MerCruiser Diesel recommends that propylene glycol
antifreeze be used in seawater section of the cooling system for cold weather
(freezing temperature), seasonal storage, or extended storage. Make sure that the
propylene glycol antifreeze contains a rust inhibitor and is recommended for use in
marine engines. Be certain to follow the propylene glycol manufacturer’s
recommendations.
3. Fill a container with approximately 5.6 liter (6 U.S. quarts) of propylene glycol antifreeze
and tap water mixed to manufacturer’s recommendation to protect engine to the lowest
temperature to which it will be exposed during cold weather or extended storage.
4. Disconnect the seawater inlet hose from the seawater pump. Using an adapter, if
required, temporarily connect an appropriate length piece of hose to seawater pump
and place the other end of the hose into the container of propylene glycol antifreeze and
tap water.
