Dear Four Winns Owner,
On behalf of everyone at Four Winns, congratulations – and thank you for choosing
a Four Winns boat.
Four Winns is committed to customer satisfaction. If you are not completely satisfi ed with
any aspect of your boat’s condition upon delivery – or if it does not meet your expectations
at any time during your ownership experience – please contact your Four Winns Dealer or our
customer service department. In the event they are unable to assist you, or if you do not receive
the response you expect, I invite you to contact me directly. Your feedback is invaluable to us
as we strive to become the world’s most customer-focused recreational boat brand.
A thorough review of this Owner’s Manual will help you make the most of your boating
experience. It not only includes information specifi c to the model you have purchased, but
guidelines for better boating as well. Please take time to familiarize yourself with its contents,
and to read – and reread often – important sections.
Once again, thank you and welcome to the Four Winns family.
Sincerely,
Jeffrey Olson
President

Owner’s Manual Page 16Operation - Section A
A - 1 GENERAL
Before starting the boat, become familiar with all of
the various systems and related operations. Be sure
all necessary safety equipment is on-board. Know the
“RulesoftheRoad”.Haveanexperiencedoperator
brief you on the general operation of your new boat.
Performa“PreCruiseSystemsCheck”.Thismanual
is a part of your boat’s equipment. Always keep it
on board.
A - 2 COMPONENT SYSTEMS
Before you can really enjoy your boat, a thorough
understanding of its systems and their operation is
essential. This manual and the associated manu-
facturers information are included in the owner’s
packet. This information is provided to enhance your
knowledge of the boat. Read this information carefully.
After becoming familiar with the boat and its systems,
reread this manual and other material provided in the
owner’s packet. Maintenance and service tips are
included to help keep the boat in like-new condition.
A - 3 SAFETY EQUIPMENT
Besides the equipment installed on the boat by
Four Winns, certain other equipment is required for
passenger safety. The “Boating Basics, A Guide to
ResponsibleBoating”,describestheFederalequip-
ment requirements and is included in the owners’
packet . These Federal requirements may also be
found on the United States Coast Guard’s website:
www.uscgboating.org/safety. Remember that these
laws are for your protection and are minimum require-
ments. Check your local and state regulations,
also. More information on safety equipment is provided
in Section B.
Items like a sea anchor, working anchor, extra dock
lines,arepistol,alinepermanentlysecuredtoyour
ring buoy, etc. could at some time save your passen-
gers lives, or save your boat from damage.
The Coast Guard Auxiliary offers a “Courtesy Examina-
tion.”Thisinspectionwillconrmtheboatisequipped
with all of the necessary safety equipment.
Operation
A - 4 PASSENGER SAFETY
You are responsible for the safety of your passen-
gers as well as for their behavior while aboard. Make
sure:
1. Each passenger is properly instructed in Personal
Flotation Device (PFD) use and keeps one within
reach in case of emergency. All non-swimmers
and children should wear a PFD at all times when
underway.
2. Passengers do not sit on gunwales, open decks,
elevated pedestal seats or on seat backs when
the boat is underway. This could cause them to
be thrown overboard during a sudden maneuver.
3. At least one other person knows how to operate
the boat in case of an emergency.
A - 5 “RULES OF THE ROAD”
As in driving an automobile, there are a few rules that
must be known if safe boating operation is to be
maintained. The Coast Guard, Coast Guard Auxil-
iary, Department of Natural Resources or your local
boat club sponsor courses in boat handling, including
“rulesoftheroad”.Suchcoursesarestrongly
recommended. Books on this subject are also
available from local libraries.
A - 6 LIGHTNING
When boating, it is important to be aware of the
weather around you. When the weather changes for
the worse, DO NOT jeopardize your safety by trying
to“rideoutthestorm”.Ifpossible,returntosafe
harbor and dock your vessel immediately.
If caught in a storm, seek shelter inside the cabin and
wait for the storm to pass. With open bow models,
suntops and campers will provide some protection,
but should not be relied on if you are able to return to
shore. Exercise care when high winds are present!
DO NOT swim or dangle legs or arms into the
water during a lightning storm. Stay out of the
water!

Owner’s Manual Page 17Operation - Section A
Lightning will seek a ground when it strikes. Avoid
contact with metal parts such as bow rails, control
handle, or windshield.
NOTICE: Four Winns boats are not equipped
with a lightning protection system.
A - 7 DRUGS AND ALCOHOL
Please keep in mind that along with the fun of boating
comes responsibility. As the owner or operator of a
pleasure boat, you are obligated (morally and legally)
to use good judgement while underway in providing for
the safety and well-being of your passengers and other
boaters around you.
Acommonandagrantviolationofgoodjudgement
and the law by boaters involves the use of alcohol or
drugs. Each year, about half of all accidents involving
fatalities involve the use of alcohol or drugs.
It is a federal offense to operate a boat while intoxi-
cated. Criminal penalties may include the termination
of operating privileges for up to one year. Many states
have passed similar laws.
Alcohol or drugs have an inhibiting effect on the
judgement and reaction time of the boat operator and
his/her passengers. Heed the advice of experts and
statisticians: DO NOT drink or use drugs when operat-
ing a boat. NEVER allow an obviously intoxicated
person to take the helm.
Have fun in your Four Winns®boat but also, have the
good sense to be mentally alert and physically capable
of operating the boat in a safe manner.
A - 8 PRE-CRUISE SYSTEM CHECK
Before leaving the dock, the following items should
be checked:
A. Before Starting The Engine
1. Check the weather forecast. Determine if the cruise
planned can be made safely.
2. Be sure all necessary safety equipment is on board
and operative. This includes items such as the run-
ning lights, horn, spotlight, life-saving devices, etc.
3. Check the bilge water level and bilge pump op-
eration.Checktheengineanddriveuidlevels.
Look for other signs of potential problems. Check
for the scent of fuel fumes.
4. Activate the bilge blower. Check the blower
output.
Gasoline vapors can explode resulting injury
or death. Before starting the engine, check
engine compartment bilge for gasoline or
vapors. Operate blower for four minutes, and
verify blower operation. ALWAYS run the
blower when the vessel is operating below
cruising speed.
5. Ensure an adequate amount of fuel is on board.
6. Besureyouhavesufcientwaterandother
provisions on board for the cruise planned.
7. Leave a written message listing details of the
planned cruise with a close friend ashore.
B. After Starting The Engine
1. Visibly check the engine to be sure there are no
apparent water or oil leaks.
2. Check the gauges. Make sure the oil pressure,
water temperature, voltmeter, etc., are reading
normally.
3. Have a safe cruise and enjoy yourself.
A - 9 ENGINE OPERATIONAL
PROCEDURES
Notice: Consult engine manual. Additional engine
information is located in Prelaunch and Underway
section.
A. Before Starting
1. Check the engine compartment for water, gas,
and/or oil leaks of any kind. Keep the bilge in a
clean condition to prevent blower and bilge pump
damage,andrehazards.
2. Checktheuidlevelsoftheengineoilandpower
