mal use by you which renders the engine or any of its
components unreasonably dangerous will void all war-
ranties and Indmar will not be liable for the resulting
damages or injuries.

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 environ-
mental label required by the California Air Resources
Board (CARB). The label has 1, 2, 3 or 4 stars. A hang-
tag, 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 rat-
ings 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 sta-
bilizer. 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.
EPA Emission-Related Warranty Requirements
Your new engine is designed, built, and equipped so it
conforms at the time of sale to the ultimate purchaser
with the requirements of CFR 40, part 1045.120. It is free
from defects in materials and workmanship that may
keep it from meeting these requirements.
The minimum emission-related warranty period is
3 years/480 hours, whichever comes first. The emission-

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 per-
formance 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, neg-
lect, 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, spe-
cial 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.

Indmar Marine Engines

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 per-
formed 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 assis-
tance.
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.
