Indmar Marine Engines
EMISSION CONTROL WARRANTY INFORMATION
The inboard engine in your
boat includes the Indmar
Emission Control System
identified as MFI. The fuel
and ignition systems on
your engine meet the
stringent requirements set
forth by the U.S.
Environmental Protection
Agency (EPA) and the
California Air Resources
Board (CARB). Indmar
also uses propylene glycol
anti-freeze in the closed
cooling system of your
engine to reduce the
environmental impact in
the event that anti-freeze
is expelled from the
engine.
Your Indmar manufactured engine has a special environmental label required by the California Air Resources
Board (CARB). The label has 1, 2, 3 or 4 stars. A hangtag, provided with your inboard engine, describes the
meaning of the star system.
Operating Fuels and Lubricants
In order to keep your engine operating efficiently and to
maintain the Emission Control System the following
requirements must be observed.
Fuel – Your engine was designed and certified to
operate on the unleaded fuels listed below. Fuel ratings must be based on the (R+M)/2 method and meet
the specifications ASTM D4814 in the US. These
fuels need no additives for proper operation.
• LS3 and LSA Engines 91 Octane
• All other Indmar Engines 89 Octane

INDM-A042
OME0502-15 Body.qxp_OM0502-05 Body.qxd 5/20/14 1:13 PM Page x
Indmar Marine Engines xi
Lubricant – Indmar uses and recommends 15W40
Marine Oil for use in all of its engines except for
the LS series engines which use Mobil 1 5W30 oil.
If marine oil is not available, any appropriate
viscosity motor oil meeting the API ratings of SL,
CI-4 is acceptable. See Chapter 6, Maintenance,
for information regarding the use of synthetic oil.
Additives – The only additive that is recommended by
Indmar for use in your engine is Sta-Bil brand fuel stabilizer. This additive helps preserve the fuel in your
tank and in the engine’s fuel system. We recommend
the use of Marine Formula Sta-Bil during off-season
storage and for the boater that consumes less than a
full tank of fuel every two weeks. See Chapter 5, Fuel,
for more information.

Indmar Marine Engines
Owner’s Warranty Responsibilities
As the inboard engine owner, you are responsible for the
performance of the required maintenance listed in your
owner’s manual. Indmar Products recommends that you
retain all receipts covering maintenance on your inboard
engine, but Indmar Products cannot deny warranty solely
for the lack of receipts or your failure to ensure the performance of all scheduled maintenance.
As the inboard engine owner, you should be aware that
Indmar Products may deny you warranty coverage if
your inboard engine or part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
The most common failures we see are due to unstable
or old fuel and lack of proper lubrication. Failures that are
attributed to old/unstable fuel or lack of lubrication are
not warrantable.
If your engine is operated in salt or brackish water, special precautions, such as flushing the engine internally
and externally, are important. See the “Salt Water
Operation” information in Chapter 6. Failures due to
corrosion are not covered by the Indmar Limited
Warranty.
You are responsible for presenting your inboard engine
to an Indmar Products service center as soon as
a problem exists. The warranty repairs should be
completed in a reasonable amount of time, generally
within 30 days.
If you have any questions regarding your warranty rights
and responsibilities, you should contact Indmar
Customer Service at 1-901-353-9930.

A new engine may use a more than normal
amount of engine oil before it is broken in.
Check your oil level hourly during the break-in
period. Once the engine is broken in, check
the oil level before each day’s use and more
often during sustained periods of high RPM or
heavily loaded operation. Marine usage is
different from automobile usage and oil
consumption is EXPECTED. Do not be alarmed
if you have to add oil between oil changes.
The following checks assumes your dealer has performed the pre-delivery service and inspection. Complete
the following pre-start check list before starting your
engine for the first time. If you have questions about any
of these procedures, see your Indmar dealer for assistance.
FIRST TIME OPERATION
1. Check the boat hull and/or garboard drain plug. Make
sure they are installed and secure. Check the boat
owner’s manual for additional pre-operation checks.
2. Make sure all engine drain plugs are installed. Refer
to Chapter 7, Storage and Winter Layup. There are
several drain locations:
Block – There are block drain points on both sides of
the engine. Some engines have brass drain plugs on
each side and some engines have knock sensors
installed in the block drain holes (Figure 1.2).
NOTICE
On the 6.0 and 6.2 Liter engines, removing the knock
sensor does NOT drain the block. Remove the caps
from the brass fittings on both sides of the engine to
drain water from the block.
Exhaust – The drain hose must be connected.
Transmission – The transmission oil cooler has one
drain plug. In addition, the Walters V-Drive and ZF
Ski-Vee (if equipped) have two drain plugs. See
Chapter 7 for instructions.

10. Start the engine (Refer to Chapter 2, General
Operation and Warnings) and allow it to reach normal operating temperature; keep a close eye on the
gauges. If any of the gauges indicate an engine
problem, stop the engine immediately and bring the
boat to your Indmar dealer for assistance.
Do not operate starter motor for more than
15 seconds without a 2 (two) minute cooldown period. Excessively long cranking
times will permanently damage the starter
motor and drain the battery.
Break-In
Taking care now to break-in your new Indmar engine is
VERY important. When properly broken in, your engine
will last longer, run better and require fewer repairs over
its lifetime. Your new Indmar engine does not require an
elaborate break-in procedure, just a little care and common sense for the first 10 hours.
Break-in Tips
• Always let engine warm up to normal operating temperature before accelerating.
• Avoid fast accelerations and don’t carry (or pull) a
heavy load during this period.
• If your boat is equipped with ballast tanks, do not use
them during the first 10 hours.
• Check engine and transmission fluid levels frequently.
During the first 50 to 100 hours, an engine can use
more oil than usual. Maintain oil at proper levels at all
times but do not overfill.
• Vary your boat speed during break-in. Do not run at
the same speed very long.
• Observe gauge readings and check for loose mountings, fittings, nuts, bolts and clamps.
• Report abnormal operation, noises or vibrations to
your dealer.
Break-in Steps
1. For the first hour, do not exceed 2000 RPM; vary
RPM continuously.
2. For the second hour, do not exceed 3000 RPM; vary
the RPM regularly.
3. For the next seven hours, do not exceed 4000 RPM;
vary the RPM regularly.

After the first ten hours but before 20 hours of operation,
take your boat to the dealer for its first engine and transmission oil and filter change and engine checkup. Your
Indmar dealer is best equipped to check the engine
immediately after break-in.
After the break-in procedure is over, your boat may be
operated at any speed. Be sure to check the wide open
throttle operating range; refer to Chapter 4, Selecting A
Propeller.
Do not exceed maximum RPM recommended
for your engine. Exceeding the maximum
RPM may result in damage to the engine.

The engine exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects or
other reproductive harm.
Operating a boat is a safe and enjoyable experience.
Indmar marine engines use gasoline for fuel. The area
under the engine and around the gasoline tank and supply lines is not open to outside air. Ventilation around
these areas must be provided by your bilge blower system and air vents located around the boat. We recommend taking time out to carefully inspect your boat at
least once a day for gasoline fumes, oil leaks, and areas
where wiring may be worn or damaged.
Explosive gasoline and battery fumes may
accumulate in your engine compartment.
Failure to properly ventilate fumes with the
bilge blower may result in explosive atmosphere resulting in death or serious injury to
you and your passengers.
Before starting engine operate bilge blower
at least 4 minutes and raise engine cover to
ventilate fumes. Inspect engine and compartment for any fluid or fuel leaks.Failure to do
so can possibly result in fire and/or explosion resulting in death or serious injury to
you and your passengers.

When refueling, make sure to open the motor box and
run the blower during and after the re-fueling operation.
Failure to do so may result in fire or explosion and may
cause death or serious injury.
Carbon monoxide gas (CO) is colorless,
odorless and extremely dangerous. All
engines and fuel burning appliances produce
CO as exhaust. Direct and prolonged exposure to CO will cause BRAIN DAMAGE or
DEATH. Signs of exposure to CO include
nausea, dizziness and drowsiness. Ensure
adequate ventilation to prevent accumulation
of CO in the boat.
Each year, boaters are injured or killed by carbon
monoxide. Virtually all of these injuries and deaths are
preventable. Carbon monoxide is a potentially deadly
gas produced anytime a carbon-based fuel, such as
gasoline, burns. Carbon monoxide sources on your boat
include gasoline engines and generators, cooking
ranges, space heaters and water heaters.
Some Indmar engines are equipped with catalytic converters which significantly reduce harmful CO emissions,
but it is important that all of the DO’s and DON’Ts still
be followed.
Please follow these DOs and DON’Ts to ensure a safe
boating experience every time.
DON’T swim or sit near the swim platform when any
engine is running.
DON’T hold on to the swim platform while the boat is
underway (no “Teak Surfing”).
DON’T moor next to another boat whose engine is
running.
DON’T confuse carbon monoxide poisoning with seasickness or intoxication.
DO immediately move the person to fresh air, investigate
the cause and take corrective action if someone on
board complains of irritated eyes, headache, nausea,
weakness or dizziness. Seek medical attention if necessary.
DO make sure generators are properly ventilated and
keep engine and generator exhausts clear.
DO always shut off engine and generator when moored,
anchored or standing still.
DO be aware that the station wagon effect, or backdrafting, can cause carbon monoxide to accumulate inside
the cabin, cockpit and bilge when the boat is underway,
moving at slow speed or idling.
DO keep your boat’s engine well-maintained and regularly
check to make sure carbon monoxide detectors in the
cabin are working properly.
DO always wear a properly fitted life jacket while in or
around water.

Never remove or modify any components of
the engine’s fuel system. Tampering with fuel
components may cause a hazardous condition that could result in severe personal
injury or death. This work must be performed
by your Indmar dealer’s technicians.
Your Indmar Marine Engine is cooled by
pumping water from the body of water that
the engine is being operated in through the
engine or through the heat exchanger on
closed cooled engines. Freezing temperatures will severely damage the engine block,
cooling system components and exhaust
system components. Contact your dealer or
see Chapter 7 for draining instructions.
Daily Pre-Start Checks
Refer to Chapter 6,
Maintenance
for checks and services.
Figure 2.1 – Pre-Start Check Points
1. Verify boat hull and/or garboard drain plug are in
place.
2. Carefully inspect engine compartment for signs of
fluid leakage and proper ventilation. Unlike autos,
marine engine compartments require positive ventilation and air re-circulation to ensure that flammable
and explosive vapors are safely dispersed in an environmentally sound manner.
