Notice to Boat Manufacturer/Installer
Throughout this publication, dangers, warnings, cautions, and notices, (accompanied by
the International Hazard Symbol) are used to alert the manufacturer or installer to special
instructions concerning a particular service or operation that may be hazardous if
performed incorrectly or carelessly. These safety alerts follow ANSI standard Z535.6‑2006
for product safety information in product manuals, instructions, and other collateral
materials. Observe Them Carefully!
These Safety Alerts alone cannot eliminate the hazards that they signal. Strict compliance
to these special instructions when performing the service, plus common sense operation,
are major accident prevention measures.
! DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
! WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
! CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor or moderate
injury.
NOTICE
Indicates a situation which, if not avoided, could result in engine or major component
failure.

IMPORTANT: Identifies information essential to the successful completion of the task.
NOTE: Indicates information that helps in the understanding of a particular step or action.
NOTE: Refer to the appropriate Mercury MerCruiser Product Applications Manual for
application recommendations.
This installation manual has been written and published by Mercury MerCruiser to aid the
boat manufacturer (OEM) in the installation of the products described herein.
It is assumed that these personnel are familiar with marine product installation.
Furthermore, it is assumed that they are familiar with, if not trained in, the recommended
installation procedures of Mercury MerCruiser product.
We could not possibly know of or advise the marine trade of all conceivable installations
and of the possible hazards and/or results of each installation. Therefore, the OEM is
responsible for any installation that does not fulfil the requirements of this manual.
It is the responsibility of the boat manufacturer to select the appropriate engine/transom/
drive package (including the correct gear ratio and propeller) for a given boat. Mercury
MerCruiser recommends that any new or unique hull/power package combination be
thoroughly water tested prior to sale, to verify that the boat performs as desired, and that
the engine operates in the appropriate RPM range.
It is recommended that a Mercury MerCruiser Product Application Engineer (PAE) be
contacted for assistance. For assistance outside the United States, contact the local
Mercury Marine office or authorized distributor.
All information, illustrations and specifications contained in this manual are based on the
latest product information available at time of publication. Mercury Marine reserves the
right to make changes at any time without obligation. As required, revisions to this manual
will be sent to all OEM boat companies.

Corrosion Protection
Mercury MerCruiser power packages are equipped with anodes to help protect them from galvanic
corrosion under moderate conditions. However, for severe conditions or if using a stainless steel
propeller, it is recommended that a Quicksilver Anti‑Corrosion Anode Kit and/or a MerCathode
System with 2 additional transom mounted anode assemblies be installed (some models have a
MerCathode System as standard equipment). A MerCathode Monitor also is available to allow the
operator to check the operation of the MerCathode System with the push of a button. (Refer to
Mercury Precision Parts Accessories Guide for part numbers.)
Boats that are connected to AC shore power require additional protection to prevent destructive
low voltage galvanic currents from passing through the shore power ground wire. A Quicksilver
Galvanic Isolator can be installed to block the passage of these currents while still providing a path
to ground for dangerous fault (shock) currents. (Refer to Mercury Precision Parts Accessories
Guide for part number.)
IMPORTANT: If AC shore power is not isolated from boat ground, the MerCathode System and
anodes may be unable to handle the increased galvanic corrosion potential.
Anti‑fouling Paint
IMPORTANT: Corrosion damage that results from the improper application of anti‑fouling paint
will not be covered by the limited warranty.
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 pressure wash anodes or MerCathode System reference
electrode and anode, as this will render them ineffective as galvanic corrosion inhibitors.
IMPORTANT INFORMATION SECTION - 1
Page 4 / 8 90-899883183 DECEMBER 2007
IMPORTANT: If anti‑fouling protection is required for boat hull or boat transom, copper base paint,
if not prohibited by law, can be used. If using copper based anti‑fouling paint, observe the following:
• Avoid an electrical interconnection between the Mercury MerCruiser Product, Anodic Blocks,
or MerCathode System and the paint by allowing a minimum of 40 mm (1‑1/2 in.) UNPAINTED
area on transom of the boat around these items.

a - Painted boat transom b - Minimum 40 mm (1‑1/2 in.) unpainted
area around transom assembly
NOTE: Sterndrive unit and transom assembly can be painted with a good quality marine paint or
an anti‑fouling paint that DOES NOT contain copper or any other material that could conduct
electrical current. Do not paint drain holes, anodes, MerCathode system or items specified by boat
manufacturer.
NOTE: Do not wash the sterndrive unit with a power washer as this can damage the coating on
the reference wire of the MerCathode assembly, if equipped, and increase corrosion.
Emission Control Information Label
A tamper‑resistant Emission Control Information label is affixed in a visible location to the engine
at time of manufacture by Mercury MerCruiser. In addition to the required emissions statement,
the label lists the engine serial number, family, STD (emission standard/level), date of manufacture
(month, year), and the engine displacement. Please note that the low emissions certification will
not affect the fit, function, or performance of the engines. Boatbuilders and dealers may not remove
the label or the part it is affixed to before sale. If modifications are necessary, contact Mercury
MerCruiser about the availability of replacement decals before proceeding.

NOTE: When the CE mark is present in the lower right corner of the Emission Control Information
Label on the engine, the Declaration of Conformance applies. Refer to the front page of this manual
for further information.

Owner Responsibility
The operator must have routine engine maintenance performed to maintain emission levels within
prescribed certification standards.
The operator may not modify the engine in any manner that alters the horsepower or allows
emissions levels to exceed their factory specifications.
Emission Certification Star Label
Your boat is labeled on the hull with one of the following star labels. The Symbol for Cleaner Marine
Engines Means:
1. Cleaner Air and Water ‑ for a healthier lifestyle and environment.
2. Better Fuel Economy ‑ burns up to 30‑40 percent less gas and oil than conventional carbureted
two‑stroke engines, saving money and resources.
IMPORTANT INFORMATION SECTION - 1
Page 6 / 8 90-899883183 DECEMBER 2007
3. Longer Emission Warranty ‑ Protects consumer for worry free operation.
Beginning January 1, 2003, one Three‑Star or Four‑Star label will be included with each
factory‑certified Mercury MerCruiser engine.
All Mercury MerCruiser engines (500 hp and below) will have a Three‑Star Ultra Low Emission
rating or Four‑Star Super Ultra Low Emission rating. The Star label identifies that these engines
meet the California Air Resources Board's Sterndrive and Inboard marine engine 2007 and later
exhaust emission standards. Engines meeting these standards have 65‑90% lower emissions than
One‑Star – Low Emissions engines.
The Star label will be affixed on the left side of the hull as shown.
