INTRODUCTION
1. THIS MANUAL
The material here and in the rest of the Owner’s
Manual Packet:
• Gives you basic safety information;
• Describes the features of your boat;
• Describes the equipment on your boat;
• Describes the fundamentals of boat use; and
• Contains service and maintenance informa-
tion.
You must learn to operate this boat as well as
read, understand and use this manual.
What this manual does not give you is a course in
boating safety, or how to navigate, anchor or dock
your boat. Operating a power boat safely requires
more skills, knowledge and awareness than is nec-
essary for a car or truck.
2. YOUR RESPONSIBILITIES
For your safety, the safety of your passengers, other
boaters and people in the water, you must:
• Take a boating safety course;
• Get instruction in the safe and proper handling
of your boat;
• Understand and follow the “rules of the road”;
• Learn how to navigate.
• Registration: In addition to the registration
requirements for your boat in the state where
it is used most frequently. Many states require
additional registration when an out-of-state boat
is used within their boundaries. Contact state
boating authorities or any marine dealer for
registration requirements.
3. SOURCES OF INFORMATION
In North America, contact one of the following for
boating courses:
• U.S. Coast Guard Auxiliary
• U.S. Power Squadron
• Canadian Power and Sail Squadrons
• Red Cross
• State Boating Offices
• Yacht Club
Contact your dealer or the Boat/U.S. Foundation
at
1-800-336-2628
Outside of North America, contact your boat dealer
and/or your governmental boating agency for as-
sistance.
A book that provides a comprehensive background
in boating is Chapman - Piloting, Seamanship and
Small Boat Handling, by Elbert S. Maloney, pub-
lished by Hearst Marine.
4. DEALER RESPONSIBILITIES
In addition to a pre-delivery check and service of
the boat, your dealer is to give you:
• A description and demonstration of the safety
systems, features, instruments and controls on
your boat;
• An orientation in the general operation of your
boat;
• An “In Service Form” completed by you and the
dealer after your inspection of the boat;

any questions, contact your dealer or call:

5. WARRANTIES
Your boat comes with several warranties.Each com-
ponent and/or system on your boat has its own war-
ranty that will be found with the specific information
and manual for that component.These are included
with your Owner’s Manual Packet. Locate and read
the individual warranties; then put them together for
easy future reference.The Sea Ray®warranty is on
the warranty information card in your packet.
6. HULL IDENTIFICATION NUMBER (HIN)
The “Hull Identification Number” located on the
starboard side of the transom, is the most important
identifying factor and must be included in all corre-
spondence and orders. Failure to include it creates
delays.Also of vital importance are the engine serial
numbers and part numbers when writing about or
ordering parts for your engine. Refer to the Engine
Operator’s Manual for locations of engine serial
numbers and record them for future reference.
7. MANUFACTURER’SCERTIFICATION
As a boat manufacturer, Sea Ray builds their
products to guidelines established under the Fed-
eral Boat Safety Act of 1971. The Act is promul-
gated by the United States Coast Guard who has
authority to enforce these laws on boat manufac-
turers that sell products in the United States. Sea
Ray ensures that all of its products comply with
these laws.
The NMMA, National Marine Manufacturers As-
sociation, provides Sea Ray with a third party
certification. The NMMA is an organization that
represents the marine industry and assists manu-
facturers, boat dealers, marinas, repair yards
and component suppliers in areas of legislation,
environmental concerns, marine business growth
and state and federal government agency inter-
action. The third party certification that Sea Ray
participates in, uses the well know Standards and
Recommended Practices of the ABYC, American
Boat and Yacht Council.
Sea Ray Boats participates extensively in the
American Boat and Yacht Council which is a non-
profit organization that develops and publishes
voluntary standards and recommended practices
for boat and equipment design, construction,
service and repair. We utilize all applicable ABYC
standards in the construction of your Sea Ray
boat.
Finally, Sea Ray sells their products world wide
and as such must conform to the various rules
and regulations required by other countries.
Most notably, are the ISO standards in Europe
which require the application of the CE (Com-
mon European) mark. This mark, much like the
NMMA certification here in the US, gives you the
boat owner specific information concerning your
craft. For more on this, turn to Section 1 • Safety,
subsections 8 and 13 which explains in detail the
CE plate and its importance.
