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
information.
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
necessary for a car or truck.

boaters and people in the water, you must:
• Take a boating safety course;

of your boat;
• Understand and follow the “rules of the road”;
• Learn how to navigate.
3. SOURCES OF INFORMATION

boating courses:
• U.S. Coast Guard Auxiliary
• U.S. Power Squadron
• Canadian Power and Sail Squadrons
• Red Cross

1-800-336-2628

6. HULL IDENTIFICATION NUMBER
(HIN)
The “Hull Identification Number” located on the
starboardside of the transom,is the mostimportant
identifying factor and must be included in all
correspondence and orders. Failure to include it
creates delays. Also of vital importance are the
engine serial numbers and part numbers when
writingaboutor ordering parts foryourengine.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
productstoguidelinesestablishedundertheFederal
Boat Safety Act of 1971.The Act is promulgated by
the United States Coast Guard who has authority
to enforce these laws on boat manufacturers that
sellproductsin the United States. Sea Rayensures
that all of its products comply with these laws.
The NMMA, National Marine Manufacturers
Association, provides Sea Ray with a third party
certification. The NMMA is an organization that
represents the marine industry and assists
manufacturers,boatdealers,marinas, repair yards
and component suppliers in areas of legislation,
environmental concerns, marine business growth
and state and federal government agency
interaction.The thirdpartycertificationthatSea Ray
participates in, uses the well know Standards and
Recommended Practices of the ABYC, American
Boat andYacht Council.
Sea Ray Boats participates extensively in the
American Boat and Yacht Council which is a
nonprofit organization that develops and publishes
voluntary standards and recommended practices
for boat and equipment design, construction,
service and repair. We utilize all applicable ABYC
standardsinthe construction of your Sea Ray boat.
Finally,SeaRaysellstheirproducts 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 (Common
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 information, turn to Section 1 -
Safety ,
subsections 8 and 12 which explains in detail the
CE plate and its importance.

! CAUTION
Safe Boating Means:
• Knowing the limitations of your boat;
• Following the rules of the road;
• Keeping a sharp lookoutfor peopleand objects
in the water;
• Not boating in water or weather conditions that
are beyond the boat’s and the operator’s
capability;
• Never boating when the operator is under the
influence of drugs or alcohol;
• Being aware of your passenger’s safety at all
times;and
• Reducing speed when there is limited visibility,
rough water, nearby people in the water, boats,
or structures.
Boating in beautiful weather and calm water
conditions can be a wonderful experience.
Pleasurable boating, however, requires
considerably greater skills than operating a land
vehicle.To obtain these skills, you must:
• Take a Coast Guard, U.S. Power Squadron or
equivalentboating safety course.Call theBoat/
U.S. Foundation at 1-800-336-2628 for
information on available courses.
• Get hands-on training on how to operate your
boat properly.
In Addition:
• Maintain your boat and its safety and other
systems as recommended in this manual.
• Havetheboatinspectedbyaqualifiedmechanic
or dealer, at least annually.
• Ensure that the Coast Guard required safety
equipmentisonboardandfunctions.(Seepageiv).
1. SAFETY LABELS
Safetyprecautionsaregiven throughoutthis manual
andlabelsare mounted at key locations throughout
theboat.Thissafetyinformationadvises the owner/
operator and passengers of imperative safety
precautions to follow when operating and/or
servicing equipment.
• Figures 1.17.1 thru 1.21.1 show the location of
the safety labels on your boat.
• Do not remove or obstruct any safety label.
• Replace any label which becomes illegible.
Replacement safety labels can be obtained by
calling your dealer or Sea Ray at 1-800-

SECTION 1 • SAFETY
2. LEGALLY MANDATED MINIMUM
REQUIRED EQUIPMENT
Consult your national boating law enforcement
agency.
The following equipment is the minimum required
by the U.S.Coast Guard for a boat from 40’to less
than 65’ [12.2 meters to less than 19.8 meters] in
length.
Personal Flotation Devices (PFD’s): One Coast
GuardapprovedTypeI,IIor III deviceis mandatory
for each person aboard. One throwable Type IV
device is also required to be on board. A Type V
device is acceptable if worn for approved use. See
Page 1.5 for a description of these PFD
classifications. Always wear a PFD when
boating.
Fire Extinguisher - Portable: With a fixed fire
extinguishing system installed in the engine and
generator spaces, the American Boat and Yacht
Council (ABYC) recommends that you have two
(2) Type B-II ABC fire extinguishers, one each
located at the helm station and outside the engine
compartment and Three (3) Type B-I ABC
extinguishers located in the galley, the crew
quarters and the cabin, near the cockpit door.
Whistle, Horn: You must have on board some
meansofmaking a loud sound signal, for example,
whistle or horn.
Visual Distress Signals: If you operate your boat
in coastal waters or on the Great Lakes, you must
have visual distress signals for day and night use
on board. At least three (3) U.S. Coast Guard
approved pyrotechnic devices marked with date
showing service life must be carried, be readily
accessible,in serviceablecondition andnotexpired.
Store pyrotechnic signals in a well-marked
waterproof container in a dry location.
Other:Your Sea Ray is equipped with the required
navigation lights, engine exhaust and ventilation
systems.
3. FIRE EXTINGUISHING SYSTEM
Your boat is equipped with an automatic fire
extinguisher system located in the engine
compartment.Inthe eventofafire,theheatsensitive
automatic head in the engine compartment will
release a fire-extinguishing vapor, totally flooding
thearea.
The switch panel contains an indicator light for the
automatic fire extinguishing system. The light will
beONwhentheignition is on and indicates that the
systemisready.Ifthelightgoesoutwhiletheignition
is on, the system has discharged.
WHEN DISCHARGE OCCURS, IMMEDIATELY
SHUT DOWN ALL ENGINES, POWERED
VENTILATION, ELECTRICAL SYSTEMS AND
EXTINGUISH ALL SMOKING MATERIALS. DO
NOT IMMEDIATELY OPEN THE ENGINE
COMPARTMENT!! THIS FEEDS OXYGEN TO
THE FIRE AND THE FIRE COULD RESTART.
Waitatleast fifteen (15) minutesbeforeopening the
engine compartment. This permits the fire-
extinguishingvaporto“soak”thecompartmentlong
enough for hot metals and fuels to cool. Have
Fumes from engine, generators, and other equipment
and appliances using burning fuel contain carbon
monoxide.
Carbon Monoxide can kill you.
Open all doors, curtains, windows, and hatches to let
fresh air circulate, when running engine, generator
or burning any fuel when boat is anchored, moored
or docked.
! DANGER
PFDREQUIREMENTSDIFFER
Depending on the state or country of operation the
operator of a vessel may be fined for failure to comply
with local or national rules regarding PFD usage.

case the fire reignites. Do not breathe fumes or
vapors caused by the fire.
A. DIESEL OPTION
See Section 7 - Accessories and Options , Page
7.12 for details on the operation of the fire
extinguishing system for diesel powered boats.
4. CARBON MONOXIDE
Symptoms of carbon monoxide poisoning are
dizziness, ears ringing, headaches, nausea and
unconsciousness. A poisoning victim’s skin often
turns cherry red. Because carbon monoxide gas
(CO) is odorless, colorless and tasteless, it is
unlikely to be noticed until a person is overcome.
Dangerousconcentrationsofcarbon monoxide will
be present if:
• the engine and/or generator exhaust systems
leak;
• insufficient fresh air is circulating where people
are present; and
• fumes move from the rear of the boat into the
cockpit and cabin area.
Even in rainy cold weather ventilation must be
maintained to avoid Carbon Monoxide poisoning.You
will get wet and/or cold.
! DANGER
Sleeping on boat requires a operating Carbon
Monoxide detection system in each sleeping location.

SECTION 1 • SAFETY
Figure 1.3.1 gives examples of boat operating
conditions that can lead to high concentrations of
carbon monoxide gas.
To minimize the danger of CO accumulation when
the engine and/or generator are running, or using
burningfuel applications.
• Besure tohavesufficient ventilationwhenusing
canvas or window-type side curtains when
underway, anchored, moored or docked.
• If the convertible top is installed, operate with
the forward hatch open and leave cabin door
open.
• Operate all burning fuel appliances, such as
charcoal, propane, LPG, CNG or alcohol
cooking devices in areas where fresh air can
circulate. Do not use such devices where there
isnonoticeableairmovement,especiallyinthe
cabin, when anchored, moored or docked.
• Donot idle engine withoutmovingboat for more
than 15 minutes at a time.
• Inspect the exhaust system regularly. (See
Section 8, Required Inspection, Service and
Maintenance.
IfCO poisoningissuspected, havethevictim breath
fresh air deeply. If breathing stops, resuscitate. A
victimoftenrevives, then relapses because organs
are damaged by lack of oxygen. Seek immediate
medical attention.
A. CARBON MONOXIDE MONITOR
Your boat has carbon monoxide (CO) monitors
mounted throughout the boat . The CO monitor is
an electronic instrument that detects CO. When
there is a buildup of CO, the monitor will alert the
occupants by a flashing DANGER light and alarm.
The CO monitors are wired through a fuse block
behind the DC distribution panel.
It is extremely important that you become totally
familiar with your CO monitor and its functions.
Read and understand the CO monitor information
and operating instructions located in your Owner’s
ManualPacket.
5. LIFESAVING EQUIPMENT
Even strong swimmers can tire quickly in the water
anddrown due toexhaustion,hypothermia,or both.
The buoyancy provided by a personal flotation
device (PFD) will allow the person who has fallen
overboard to remain afloat with far less effort and
heatloss,extendingsurvivaltimenecessarytofind
and retrieve them.
Boat operators are required to carry one wearable
personalflotation device(TypeI,II, III orV)forevery
persononboard. Boats must also have at leastone
throwable device (Type IV).
The law requires that PFD’s must be readily
accessible,ifnot worn. “Readily accessible” means
removed from storage bags and unbuckled. But,
children and nonswimmers must wear PFDs at all
times when aboard. It is common sense to have
everyone on board wearing PFDs. A throwable
devicemustalso be right at hand and ready to toss.
A. PFD CLASSIFICATIONS
Off-Shore Life Jacket (Type I)

Special-Use Devices (Type V)
sailboat harnesses, white-water
vests, float coats, and hybrid
vests which have minimum
inherent buoyancy and an
inflatable chamber.
Before purchasing PFDs, ensure that there is an
attached tag indicating they are approved by the
U.S. Coast Guard or by your national boating law
enforcement agency.
Children and nonswimmers must wear PFDs
at all times when aboard. All passengers and
crew should wear them. A loose PFD is often
useless in an emergency.
Theoperator is responsible forinstructingeveryone
aboard on the location and use of PFDs.
Size PFDs for the wearer. Children require special
attention in the use of PFDs.
Test PFD buoyancy at least once a year.

7. IMPAIRED OPERATION
Drugsand/or alcoholwill preventyoufromoperating
your boat safely. This single factor is involved in
more marine accidents and deaths than any other.
The detrimental effects of alcohol and drugs are
increased by the wind, waves and sun, quickly
impairingyourability to react properly and promptly
in an emergency.
8. LOAD CAPACITY
A. UNITED STATES
Use common sense and sound judgement when
placingequipmentand/or passengers in your boat.
The number of people on board must be reduced if
you go out in poor weather and rough water.
• The number of seats does not indicate how
many people a boat can carry in poor weather
and rough water.
• Above idle speed, all passengers must be
seated on the seats provided.
TheUnited States Coast Guard doesnot provide
specific numbers for passenger capacity or
cargo weight for recreational vessels larger
than 20 feet (6.09). For safety sake, use the
following information provided for the
international loading standards for maximum
number of passengers plus cargo weight.
B. INTERNATIONAL

The information present on the certification plate
doesnot relievetheoperatorfrom responsibility.Use
commonsense and soundjudgementwhen placing
equipment and/or passengers in your boat.
• Donot load to capacityinpoor weather orrough
water.
• The number of seats does not indicate how
many people a boat can carry in poor weather
and rough water.
• Above idle speed, all passengers must be
seated on the seats provided.
9. POWER CAPACITY
The engine options available for your boat have
been selected as the best suited for general use
for this size boat. Do not install an engine larger
than the largest option available.Your boat will be
difficult to handle and will be less stable.
Your Sea Ray®has been equipped with a propeller
which our tests have shown to be the best suited
for general use with our engine under normal
conditionsand load. Donotchange the pitchofyour
propeller without getting your dealer’s
recommendations first. If you change to a different
propeller pitch, under no circumstances use a
propeller which allows the engine to operate at
higher than recommended RPM (your engine
manual specifies the maximum recommended
RPM).
To maintain rated power, propellers should be free
of nicks, excessive pitting and any distortions that
alterthemfromtheir originaldesign. Badlydamaged
propellers should be replaced, but those that are
chipped, bent or merely out of shape can be
reconditioned by your marine dealer.
It is advisable to carry an extra propeller aboard in
case you damage the one in use.
10. STABILITY
Your boat was manufacturedto specific stabilityand
flotation standards for the capacity shown on the
certification plate. Any increase from the
recommended load capacities will put your boat in
jeopardy of capsizing, swamping and/or sinking.
INA DDITION:
• Stability may be substantially reduced if
equipment is added above the deck.
• Stabilityis substantially reduced by loose fluids
or weight within the hull. Keep bilge area as dry
as possible, and close all openings, hatches
and windows in rough weather.
11. MAINTAIN CONTROL
On the water there are no marked traffic lanes, no
trafficsigns orlights, andboatshave noturn signals.
The boat operator must keep his or her attention
focusednotonlyonwhat’s ahead but what’s on the
left, right and behind the boat.
The operator must always be alert to approaching
boats (from the rear, right and left sides, as well as
those ahead). There can be people in the water,
partially submerged debris, and other navigational
hazards such as rocks, sand bars and dangerous
currents, to name a few.
Distribute passengers and gear as uniformly as
possible from front to rear and left to right.
The manufacturer’s load rating is the maximum
allowed under calm conditions.
Reduce boat loading if weather, water or other
conditions are adverse.
! WARNING
When engine is running, keep passengers away from
areas not designed for riding, such as seat backs,
bow, gunwales, transom platform, swim platform,
front and rear decks and on sun pads.
Passengers can fall overboard if not seated properly
on the seats provided.
! WARNING

390Sundancer® ( 425Sundancer

1.8
SECTION 1 • SAFETY
Your passengers are relying on you to operate and
maneuver the boat safely so that they are not in
danger of going overboard. If you turn to quickly,
increase or decrease speed abruptly, your
passengers are at risk of being thrown overboard
or thrown about the boat.
When visibility becomes impaired because of
weather, time of day or high bow angle you must
slow down so that you have sufficient time to react
if an emergency occurs. Nearby boats face similar
risks in avoiding a collision with you.
A. GENERAL CONSIDERATIONS
• Know how your boat handles under different
conditions. Recognize your limitations and the
boat’s limitations.Modify speed in keeping with
weather, sea and traffic conditions.
• Instruct passengers on location and use of
safety equipment and procedures.
• Instruct passengers on the fundamentals of
operating your boat in case you are unable to
do so.
• You are responsible for passenger’s actions. If
they place themselves or the boat in danger,
immediately correct them.
12. WEATHER
There are four design categories of boats based
upontheir ability to withstand windandsea or water
conditions. Your boat rating is displayed on the
certification plate located near the helm. Do not
operate your boat beyond the conditions listed for
your boats rating.
A. Ocean
Wind speed: above 40 knots (46 mph)
Wave height: above 4 meters (13 feet)
Boat may be used for extended ocean
voyages.
B. Offshore
Maximum wind speed: 40 knots (46 mph)
Maximum wave height: 4 meters (13 feet)
Boat can be used offshore, but not for
extended ocean voyages.
C. Inshore
Maximum wind speed: 27 knots (31 mph)
Maximum wave height: 2 meters (6.5 feet)
Boat use is limited to coastal waters, large
bays, estuaries, lakes and rivers.
Death or serious injury can result if you fail to observe
these safety rules:
• Anyone who controls the boat must have
taken a boating safety course and have
trained in the proper operation of the
boat.
• Always operate the boat at speeds that
will not put people or property in danger.
• Be constantly aware of conditions in all
directions when underway and before
turning.
• Reduce speed, use a lookout to identify
possible hazards or difficulties, and turn
on navigation lights when:
- visibility is impaired;
- in rough water; and
- in congested waterways.
• Watch your wake. It can capsize a small
boat or damage moored boats or other
property.You are responsible for damage
caused by your wake.
