Chapter 2: Safety
REQUIRED SAFETY EQUIPMENT
The US Coast Guard (USCG) requires that every boat have specific equipment on board.
Check with local regulations on mandatory equipment apart from the list of Coast Guard
requirements. See Sportfish, Cruisers, Yachts Owner’s Manual, page 17, for details on the
following required safety equipment.
•Fire Extinguisher
Boats should be equipped with a marine approved fire extinguisher.
• Personal Flotation
All passengers must have an USCG approved personal flotation device (PFD).
Children and non-swimmers are advised to wear a PFD at all times.
• Sound Signaling Device (Horn, Bell Or Whistle)
Your Grady-White is equipped with a horn that meets USCG requirements.
• Visual Distress Signals
USCG approved visual distress signals are required on U. S. waters. See page 33 of the
pamphlet Sportfish, Cruisers, Yachts Owner’s Manual enclosed with this manual for more
information.
• Lighting
Grady-White boats are equipped with navigational lights that meet requirements for
recreational vessels for inland and international waters.
ADDITIONAL RECOMMENDED EQUIPMENT
In addition to the required safety equipment, there are additional items that will provide an
extra margin of safety and convenience for you and your passengers while boating. For an
extended list of basic gear, tools and spare parts, reference page 18 of the pamphlet Sportfish,Cruisers, Yachts Owner’s Manual enclosed with this manual.
Keep tools and spare parts in good condition. Replace parts removed from spare parts kit.
Most importantly, use US Coast Guard approved or marine certified parts where applicable.
Conditions found requiring corrective action should be worked on by a qualified repairman.
REGISTRATION NUMBERS
Federal and State laws require a powerboat to be registered in the State where it is primarily
used. Registration numbers and validation stickers must be displayed according to regulations.
The registration certificate must be on board when boating. The boat serial number or Hull
Identification Number (HIN, page 1–2) is required on the registration form. The HIN is located
on the upper right hand corner of the transom, and is the most important identifying factor. The
HIN should be included in all documents and correspondence to provide you timely service.
2–1
S AFETY
EMERGENCY STOP SWITCH
All Grady-Whites are equipped with an emergency stop switch. This is a safety feature that if
used properly will shut the engine(s) down if the operator leaves or falls from the helm position.
The ignition shutdown system includes a shut-off switch, switch clip, lanyard and lanyard clip.
The lanyard clip is attached to the operator. If a situation arises where the boat should stop, a pull
on the cord to release the clip from the shut-off switch will shut down the engine(s). To reset the
emergency stop switch, simply reinstall the switch clip. The decision to use the emergency stop
switch rests with the owner/operator. See page 72 in Sportfish, Cruisers, Yachts Owner’s Manual.
EMERGENCY INFORMATION
While boating, unpleasant situations may develop. You should prepare yourself on how to
cope with them whether they happen aboard your vessel or someone else’s. Anticipate and game
plan for specific situations such as fire, man overboard, collision, etc. to give you the confidence
and ability necessary to handle an emergency. The key is to remain calm. For emergency
procedures, see Section 4 in Sportfish, Cruisers, Yachts Owner’s Manual.
• Rendering Assistance
The owner or operator of a vessel is required by law to render all practical or necessary
assistance to any person or vessel affected by collision, accident or casualty. However, you
are not required to endanger your vessel or passengers to render assistance.
• Accident Reporting
Report all boating accidents to your local authorities. Federal regulations require boat
operators involved in an accident to submit a written report within 48 hours. In the event of
death or disappearance, notification is required immediately by phone or radio in addition
to the written report. These reports can be submitted to the State Boating Law Administrator.
Forms can be obtained through the USCG, local harbor patrol offices, sheriff, and police
stations.
• Lightning Precautions
This awareness is included to ensure the safety of the owner and passengers. Always be
mindful of the weather! When a lightning storm advances, certain safety precautions should
be taken. Dock the boat and seek shelter on land. If this is not possible, seek refuge inside the
boat until the storm has passed. Stay out of the water! Lightning will seek a ground when it
strikes and may pass through metal components if it hits your boat. For this reason, avoid
contact with metal parts of the boat under these conditions.

BOATING SAFETY TIPS
Safety is an important aspect of boating. Your safety as well as the safety of your passengers
and vessel is your responsibility. The following precautions and the ones mentioned in section 1
of Sportfish, Cruisers, Yachts Owner’s Manual will add to you and your passengers’ boating
safety and pleasure.
• Before operating your Grady-White READ AND STUDY ALL OPERATION ANDMAINTENANCE MANUALS. It is important that you fully understand how to use your
boat. Contact your Grady-White dealer for questions. Proper use and service will insure quality
performance and longevity of your boat.
• A written float plan left with a RESPONSIBLE person can serve as valuable information
should you not return as scheduled. Upon returning, your primary responsibility is to notify the
person of your return.
• NEVER operate or allow anyone to operate your boat while under the influence of drugs or
alcohol.
• Individuals under the age of 16 should not be allowed to operate your boat.
Inexperienced drivers should have constant and direct supervision.
• Instruct at least one passenger on the fundamentals of basic boating and safe operation in the
event of an emergency.
• While boating, passengers should be settled in a safe position. Use hand holds and rails for
steadiness. Do not allow bow, transom or gunwale riding. The captain is ultimately responsible
for their passenger’s safety.
• Keep your boat speed under control. Respect for other boaters and those on shore are common
courtesies. The boat’s operator is responsible for injury or damage caused by the boat or the
wake. Your wake could swamp a smaller craft and endanger its passengers. Stay alert for
posted “No Wake Zones”.
• Become familiar with the handling personality and limitations of your boat.
• Never allow swimmers/skiers to enter or exit the boat with engine(s) running. A shift lever
in neutral could become engaged accidentally. Also, exhaust fumes from the outboard
engine(s) contain carbon monoxide gas. These fumes may concentrate in this area. See more
information on “Dangers of Carbon Monoxide” on page 2-5.
• Obtain information and a chart for new areas when possible.
• Clean water and air are responsibilities for all persons. Use litter containers on board and
dispose of refuse properly. See “Pollution Regulations” on page 3–3.
• Know and obey the “Rules of the Road”. See Sportfish, Cruisers, Yachts Owner’s Manual,
beginning on page 19, for a better understanding of right of ways, signals and waterway
markers.

S AFETY
CERTIFICATION
At the helm station you will find a NMMA (National Marine Manufacturers Association)
Yacht Certification tag. This means your yacht complies with the Coast Guard safety standards.
(NOTE: Any boat with an overall length of 26 feet or greater is defined as a “yacht” by NMMA.)
This label means your Grady-White is certified by the NMMA. With
this tag, you are assured your fuel system, electrical system, lighting,
ventilation, and steering are not only in compliance with the US Coast
Guard regulations, but also meet the more stringent standards of the
NMMA. The NMMA is a national trade organization serving all
elements of the recreational boating industry including manufacturers
of boating equipment. With this tag, you can have confidence in the
safety of your boat.
This label means that Grady-White has designed and built your boat to the ABYC standard
H-8, buoyancy in the event of swamping. Basic flotation is defined as having enough foam in the
boat to create buoyancy and prevent sinking under swamped conditions.
LOADING CAPACITY
Though overloading is a primary cause of many boating accidents, improper loading is
equally hazardous. Boaters should know the amount of weight on board and evenly distribute the
weight within the boat.
2–4
SAFETY
CARBON MONOXIDE
W A R N I N G
!
(CO) is produced by all combustion engine(s) and generator sets.
Avoid brain damage or death from carbon monoxide.
Keep cockpit and cabin areas well ventilated.
Avoid blockage of exhaust outlets.
Signs of exposure include headache, nausea, dizziness and drowsiness.
Carbon Monoxide, commonly written (CO), is a colorless, odorless gas emitted from any
boat’ s exhaus t. The gas is s imila r in weight to the air we breathe. Therefore, it cannot be expected
to rise or fall, but will accumulate in confined spaces.
Carbon monoxide is poisonous, and potentially fatal if breathed over an extended period of
time. Symptoms of CO poisoning include dizziness, nausea, headache, sleepiness, vomiting,
throbbing in the temples, muscular twitching, and an inability to think clearly. If you or anyone
else experience these symptoms, immediately get away from fumes and into an area where
plenty of FRESH air can be consumed. If any symptoms from above persist, seek medical
attention.
Carbon monoxide can accumulate in cabins and under canvas. If your boat is equipped
with a canvas that encloses the aft cockpit and propulsion equipment, do not operate the boat with
this canvas closed.
Outboard engine exhaust fumes contain carbon monoxide. These fumes may concentrate at
the motorwell area. Do not board your vessel with the engine(s) running. Also, do not occupy the
motorwell area with the engine(s) running.
Operators need to be aware of the influence of other boats on their vessel as well as the effects
they have on neighboring crafts. Of primary concern is the operation of an auxiliary generator
with boats moored along side each other. This situation creates an atmos phere which is filled with
CO, and extremely dangerous.
W A R N I N G
!
BE AWARE of the significance your exhaust may have on other vessels. Likewise, BE AWARE
that the operation of other vessel's equipment may influence the carbon monoxide concentration
on your vessel.
W A R N I N G
!
Exhaust fumes from engine(s) contain (CO). Boats with canvas deployed are more likely to collect
exhaust fumes. Avoid brain damage or death from (CO). Keep cockpit and cabin areas well
ventilated. Signs of exposure include headache, nausea, dizziness and drowsiness.

FUELING
W A R N I N G
!
Safety during fueling requires CAUTION and COMMON SENSE.
Please study the following precautions carefully. Consult your dealer if you have any
questions. Prior to your initial fill-up, check your engine manual to confirm the type of fuel and
octane rating specified by the manufacturer. Tanks should be filled when the boat is not in use to
reduce the accumulation of moisture and condensation. Add stabilizer to fuel that won’t be used
in 60-90 days.
Fuel containing up to a 10% ethanol blend (E10) is acceptable for use in your boat. Do not use
alcohol blended fuel that has greater than 10% ethanol such as E20 or E85. These concentrations
may be harmful to fuel system components and outboard engines.
Other considerations related to Ethanol fuel blends:
•Avoid mixing E10 with fuels that contain MTBE, an additive to gasoline in some fuel
blends that oxygenates the fuel to reduce emissions.
• Use a 10 micron fuel filter to capture particulate contaminants that may be loosened from
the fuel system due to the solvent nature of alcohol blended fuels.
• Carry spare fuel filters with a 10 micron rating on your boat for emergency replacement if
required.
• Before Fueling
•Shut down all engines.
•Turn battery select switch(es) to “OFF” to insure that all fans, lights, etc. are off.
•Close all ports, hatches, windows and engine compartments to prevent fumes from
accumulating in closed areas.
•Extinguish cigarettes and all other lighted materials.
•Have a fire extinguisher near.
• During Fueling
•Observe all safety regulations for the safe handling of fuel.
•Keep the fuel supply nozzle in contact with the fuel tank opening to prevent any static
sparks.
• After Fueling
•Secure the fuel cap, and check fuel lines and connections for leakage. Wash and clean up
any spilled fuel. Dispose of clean up rags or sponges on shore. Do not store these clean up
rags in the boat.
•After fueling ventilate all ports, windows, hatches and other closed areas. Conduct a “sniff
test” to make certain all fumes are vacant before using the battery select switch(es).
3–1
G ENERAL INFORMATION
•If your boat is equipped with two fuel tanks use the fuel select valve (see “Fuel Select
Valve” on page 3–3) to select the main or aux tank. Select the tank to be used first taking
into consideration the distribution of your load as fuel is consumed. Performance will be
influenced by weight distribution.
See warnings and check list in Section 6, page 37 of the Sportfish, Cruisers, and YachtsOwner’s Manual. Reference “Fuel Tank Compartment” on page 6–7 for more information on
cleaning the fuel storage area.
FUEL SYSTEM
After fueling, inspect the fuel hoses, connections, and tanks for signs of leaks or deterioration.
Annually conduct a more detailed inspection of fuel system components, especially those hidden
from routine inspection. Replace deteriorated hoses, clamps, connections or fittings immediately.
If you are experiencing fuel flow problems, there is a simple method to determine if the
problem is in your fuel system or your engine. Connect a six-gallon portable tank to your engine.
If the problem persists, the likely cause is with the engine itself. If the problem goes away, the
source must be in the boat’s fuel system. One component that should be inspected if a restriction
occurs is the anti-siphon valve. If fuel does not flow properly through this part it must be cleaned
and/or replaced. Do not remove the anti-siphon valve and replace with a regular barb.
3–2
G ENERAL I NFORMATION
FUEL SELECT VALVE
If your boat is equipped with dual fuel tanks, you will have a manual fuel select valve
installed. This valve allows you to choose from which tank fuel will be consumed. Remember, as
the fuel is consumed and the fuel load redistributes the performance will be influenced. Select the
tank that allows the best performance for your boat.

POLLUTION REGULATIONS
The U.S. Coast Guard defines restrictions on the discharge of oil or hazardous substances and
plastics or garbage in the “Federal Requirements for Boating and Boating Safety”. You should
have received this pamphlet when you registered your boat. Detailed below is a summary of those
regulations. You should read the pamphlet and become familiar with any local restrictions where
you operate your vessel. Passengers or crew members aboard your boat should also be notified of
these regulations.
3–3
G ENERAL INFORMATION
Discharge of Oil or Hazardous Substances
The Federal Water Pollution Control Act prohibits the discharge of oil or hazardous
substances, which may be harmful, into or upon U.S. navigable waters. Vessels 26 feet in
length or over must display a placard at least 5” x 8”. The placard should state the following:
Disposal of Plastics or Garbage
The MARPOL ANNEX V is the Act to prevent pollution from ships and other vessels.
Federal regulations prohibit the discharge of plastic garbage anywhere in the marine
environment. Plastic includes, but is not limited to: synthetic fishing nets, ropes, lines, straws,
six pack holders, styrofoam cups and lids, bottles, buckets and plastic bags. These regulations
also restrict the disposal of other types of garbage within specified boundaries from shore.
Any vessel 26 feet and over must display the placard below or a similar version which details
the regulations. The placard must be at least 4” x 9” and should be available from your dealer.
TRAILERING
The adjustment and balance of your boat on the trailer determines how easily your boat may
be transported. The tongue weight on the hitch ball should be 5-10% of the total weight of your
boat, motor and trailer. Tail-heavy loads cause swaying while trailering. The rollers and/or
bunkers of your trailer should be adjusted so that the weight is distributed evenly across the stern
and forward throughout the keel sections. Your dealer can help adjust your trailer properly.
3–4
G ENERAL I NFORMATION
Practice maneuvering the trailer; the trailer always backs in the opposite direction of the
vehicle. To maneuver the trailer, turn the steering wheel in the direction you want the trailer to go.
Familiarize yourself with this manual and all aspects of your boat prior to initial launch. At the
launch site, go through a pre-launch checklist. The list should be suited to your specific needs.
Trailering and relative information can be found on page 94 in Sportfish, Cruisers, YachtsOwner’s Manual.
PREDEPARTURE
See the checklist on page 35 in Sportfish, Cruisers, Yachts Owner ’s Manual before starting
out.
CASTING OFF & APPROACHING THE DOCK
Unlike an automobile, the stern of your boat reacts first when turning. A turn to the right will
swing the stern to the left and vice-versa. Remember that turning your boat away from an object,
such as a dock, will tend to swing the stern toward that object. Reference procedures for casting
off and approaching the dock on page 42 of Sportfish, Cruisers, Yachts Owner’s Manual.
ANCHORING
Some factors that determine the size and type of anchor most suitable for your boat include
the size of your boat and the type of lake, sea or river bottom in your boating area. Sportfish,Cruisers, Yachts Owner’s Manual has a list of tips concerning anchoring starting on page 46.
N O T I C E
It is illegal to tie your boat to navigational aids such as buoys and markers.
W A R N I N G
!
Never anchor off the stern of the boat especially in strong winds or currents. The weight of the
stern and flat surface to the seas can easily cause water to enter over the transom and swamp the
boat.
3–5
G ENERAL INFORMATION
TOWING
In the event of a mishap or power loss you may need to tow a boat or be towed. You should
not tow a boat larger than your own. Always use safety and good judgement when towing. Never
tow a boat if you are not equipped with the proper lines. Passengers should never grasp a towline.
It should be secured to the boat. See page 30 in Sportfish, Cruisers, Yachts Owner’s Manual.
Before towing a boat, make a bridle and tie it securely to the pad eyes on the transom with
enough slack to clear the engines. Pad the line wherever it comes into contact with the boat to
prevent chafing. Attach a tow line to the bridle so that it can slide from side to side to prevent too
much pressure on a single pad eye. The tow line should then be attached to the bow eye or to a
bridle on the towed boat. The tow line should be a minimum of twice the length of the towing
boat, the longer the better. Do not try to run in too close when passing the towline to the other
boat. Send either a light line or attach the towline to a life preserver to be pulled in. Be aware of
the other boat’s propeller.
The towed boat should always have someone at the wheel since the boat may swing off
course. Start the tow off slowly; a steady pull at a moderate speed should be used. It is important
to keep the slack out of the propeller area. Watch the action of the towing boat. If excessive slack
develops in the towline and contact is obvious, turn in either direction to avoid hitting the stern.
W A R N I N G
!
As a precaution, passengers on both boats should stay clear of the towline; lines under stress could
snap and fly in either direction causing injury.
SHALLOW WATER
Most boats that become grounded can be floated off with engine(s) tilted to reduce the draft at
the transom. With motors tilted, try rocking the boat from side to side to break the suction of mud
from the keel. Move passengers or heavy objects from the point where the boat is grounded. Do
not lower or start the engine(s) until the boat is clear of the ground. Refer to page 53 in Sportfish,Cruisers, and Yachts Owner’s Manual.
C A U T I O N
!
Do not lower or start engines if the propeller is in mud or sand. Wait until the boat is refloated to
avoid damage to the cooling system of your engine.
Be mindful of water level fluctuations when boating in water with tidal changes. If you are
grounded on an incoming tide, you can wait until the tide is high enough to refloat your boat.
However, on an outgoing tide, quick action should be taken to refloat your boat. If this is not
possible, set an anchor to keep the boat from becoming driven further aground. Set the anchor to
counter the action of the wind or current. The anchor, in some cases, can also be used to pull the
boat free.
Many inland areas have rocks and stumps which could crack or puncture a fiberglass hull. Be
familiar with the boating area, and use caution in shallow water.
3–6
G ENERAL I NFORMATION
WINDLASS
Anchoring can be less laborious if your boat has a windlass accessory . If your boat is equipped
with a windlass, reference your windlass Operation Manual for instructions.
GENERAL INFORMATION ON BOAT HANDLING
The best method of learning how to handle and obtain the best performance from your boat is
to practice and experiment. After several hours of operation, you should experiment with the
throttle settings to discover the setting that will be the most comfortable and economical range for
your particular load conditions.
We suggest that you make a speed and RPM chart to obtain the most economical operation.
Operate the boat at various speeds and check the fuel consumption. Compute the amount of
operating time remaining when the fuel gauge has only one bar remaining on the display. Make a
log of this type of information and have it available when using your boat. Other statistics you
may want to determine could include the following:
• Minimum speed for effective steering.
• Turning radius at different speeds.
• Response to steering at low speeds.
• Accelerating and deceleration rates.
• Time and distance to bring the boat to a stop at different speeds.
• Control of the boat using both engines in close quarters.
Also read the section in Sportfish, Cruisers, Yachts Owner’s Manual beginning on page 49 for
information on safe operating speed.
TWIN ENGINE BOATS
T win engine boats are easier to maneuver than si ngle engine crafts. However, they still require
practice to ensure comfortable operation. The boat will run ahead or backward in a straight line
when both engines are working together at the same speed. The engines also can be used to steer
to port as well as starboard. Moving ahead on one engine will cause the bow to swing away from
the running engine side and to move forward at the same time. Backing up with one engine will
cause the bow to swing toward the running engine side and the boat to move backward. Running
one engine ahead and one engine astern will cause the boat to turn end-for-end in little more than
its own length. Running both engines in the same direction at different speeds will cause the boat
to move in the direction dictated by the faster engine but its influence will be modified by the
slower engine.

PERFORMANCE
Chapter 4: Performance
PERFORMANCE FACTORS
Maximum performance is dependent on many factors and cannot be guaranteed. These factors
will vary with changing conditions. Some of these factors are listed below. Reference the troubleshooting guide on page 65 in Sportfish, Cruisers, Yachts Owner’s Manual for additional
suggestions on adjusting performance.
Engine Efficiency
Engines operate most efficiently when they are properly tuned, and the props are in good
condition. Efficiency will decrease if normal care and maintenance is not performed.
Neglecting the engines will cause power to drop and speed to decrease. In addition, expensive
repairs may become necessary. Be sure to follow all instructions in the engine operation
manual(s).
Weather Conditions
Weather conditions sway engine performance. Barometric pressure and humidity affect
horsepower. A change of weather could amount to a 10% loss in horsepower on some hot
days.
Load Distribution
A decrease in performance will be noted when gear, equipment, passengers, and fuel are
added. This extra load will affect the performance of your boat according to the distribution of
the weight. Another type of extra load that could affect performance is the accumulation of
water in the bilge. Keep the bilge dry to eliminate this type problem.
Marine Growth
Maximum performance is obtained only when your hull bottom is clean. Marine growth on
the bottom of the boat will increase resistance and decrease speed. These conditions will also
increase fuel consumption. Reference “Cleaning” on page 6–1 for more information on
cleaning your hull bottom.
Trim
The outboard engines are equipped with power tilt and trim mechanisms. The purpose of
power tilt is to raise the engine(s) for launching, loading or trailering. Power trim may be
used to adjust the boat’s planing performance and running attitude. See power trim, page 52
and 72, in Sportfish, Cruisers, Yachts Owner’s Manual.
Trim refers both to the weight distributions inside the boat and to the angle of thrust of the
engine. The angle of thrust of the engine forces the bow up or down. The trim tabs on your
boat also control the trim of the boat, similar to the po wer trim. Refe r to the Trim Tabs section
in Chapter 8 for additional information.
4–1
P ERFORMANCE
Propeller
The condition of your prop has a major influence on the performance of your boat. Your
engine(s) should be equipped with the best size prop for normal conditions. Unusual uses or
weight conditions may require special props. A damaged prop can affect your boat's top
speed, cause vibrations, create a sudden drop in RPMs or even increase fuel consumption.
C A U T I O N
!
Stay within the engine manufacturer's maximum and minimum RPM ranges when replacing
props. This information is located in your engine manual.
PitchDiameter
Diameter = 14Pitch = 14
Diameter and pitch are the two basic dimensions of a propeller. Diameter is the distance
across the circle made by the blade tips as the propeller rotates. Pitch is the theoretical (not
accounting for slippage) forward distance the propeller would move in one revolution. An
example of a propeller dimension would be 14 X 17 for a propeller having a diameter of 14”
and a pitch of 17”.

STEERING
Most outboard engines are equipped with an adjustable rudder trim tab. This trim tab should
be adjusted to balance the steering at the speed which you travel most frequently. Variations in
speed, boat load or engine trim will cause the steering to pull in one direction. If the boat pulls to
the left, adjust the trim tab to the left and vice-versa.
• Hydraulic Steering
Hydraulic steering systems (not to be confused with power steering) require regular
preventative maintenance for continued safe and reliable operation. The oil level in the helm
pump must be maintained within acceptable operating levels. A low oil level will allow air to
get into the steering system and result in unresponsive steering. The oil level should always be
within 1/2 inch from the base of the fill hole, located on the front top portion of the helm
pump. Check the entire steering system regularly for oil leaks. Unobserved leaks over a period
of time will result in unresponsive steering and possibly loss of steering. Refer to the steering
manual for specific recommendations and additional maintenance requirements.
Any slow or sudden change in the “feel” of your steering system indicates an immediate need
for a thorough inspection. All repairs and replacements to steering systems should be made
only by a qualified marine technician.
• Tilt Steering
This feature enables the operator to tilt the wheel up or down. Refer to the steering system's
manual for information on oil levels with hydraulic tilt steering.

PERFORMANCE
THROTTLE/SHIFT CONTROL
The throttle/shift controls located at the helm station control the flow of fuel to the engine.
They also act as gear shift levers to control the forward and aft thrust of the propellers.
The middle position of the throttle control is the neutral position. Move the control forward to
engage the shifting mechanism which creates a forward thrust of the propeller. Advance the
forward movement to increase the fuel flow to the engine and boost the forward lunge.
Move the control lever aft of the neutral position to reverse the shift mechanism and create a
reverse thrust of the propeller. Increase the aft movement to increase the reverse thrust.
Remember that propellers are designed for maximum forward thrust; so, reverse thrust will not be
as efficient.
All controls have a neutral safety mechanism. This mechanism will not allow the engine to
start when the control is in gear. You may use the neutral lock out feature on the control handle to
increase the flow of fuel to the engine while remaining in the neutral position.
Neu tral Lo c k-o ut B u tton
for Mechanical Shifter is
located on starboard handle.
Reverse the shift mechanism to stop a boat that is moving forward. This change in direction
will provide a “braking action” and slow the boat.
C A U T I O N
!
The braking action causes a wake which may wash over the transom and flood the boat if the
vessel is moving too fast. Allow engine RPMs to decrease before shifting into reverse.
If your boat has mechanical controls, there will be control cables that operate the shift and
throttle functions on the engine. If your throttle or shift cables need replacing, use the same style
and length as the original equipment.

Chapter 6: Maintenance and Service
GENERAL
The amount of maintenance required to keep your boat operating properly and to maintain the
appearance is dependent on how the boat is used, amount of usage, salt or fresh water, geographic
location, etc.
Your hull and deck are constructed by the “hand lay-up method” using the highest quality
fiberglass mat and woven roving. This method of construction ensures a proper fiberglass-to-resin
ratio and uniform thickness resulting in a much stronger boat than those constructed of “chopped
glass”. This process ensures your Grady-White is the strongest, most durable fiberglass boat
possible.
Keep the bilge area clean and dry. Leaks found early and corrected will less likely cause
damage. Do not allow grease, grime, and dirt to build up.
While proper maintenance of your boat is a source of pride, it is also key to maintaining your
boat's value. A few simple steps will keep your fiberglass Grady-White looking showroom bright
for years.
EXTERIOR FIBERGLASS FINISH
The exterior finish of your Grady-White is a thin layer of resin with a finished color pigment
called gel-coat. It is used for cosmetic purposes and makes routine maintenance relatively simple.
Although gel-coat has a hard smooth surface, it does contain microscopic pores that will allow
surface discoloration if not kept clean.
Maintenance
Normal exterior finish maintenance of your Grady-White is similar to the care you would give
your automobile. Do not use caustic, highly alkaline cleaners or those containing ammonia.
These cleaning agents may darken gel-coat. The resulting stain is a chemical reaction and can
be removed with a rubbing compound followed by waxing. Also, using common household
bleach (chlorine) may damage the gel-coat finish just like bleach can damage clothing with
colors. Bleach impacts solid colors by causing blushing or fading and for this reason should
not be used on gel-coat.
Cleaning
The best way to prevent discoloration and soil build-up is to hose the boat with fresh water
after each outing or on a regular basis. This build-up is the result of use and environmental
pollutants. Clean the boat regularly with a mild household detergent and plenty of fresh water.
Avoid strong detergents, citrus based cleaners, or bleaches. These products are potentially
harmful to the appearance and durability of your boat’s gel-coat. Always read the label before
using any cleaning product to make sure it says safe for use on fiberglass finishes. Use a
sponge on smooth surfaces and the deck. A brush can be used on the nonskid areas. Rinse
away all grime and residue.
6–1
M AINTENANCEAND SERVICE
Finish/Waxing
Gel-coat will age or dull naturally due to constant exposure to the natural environment and
pollutants. Discolorations are shallow in depth. Factors that will affect the rate of
discoloration are: the sun, pollution, old wax accumulation, and the salt content of water.
Polishing compound (fine abrasive) or rubbing compound (coarse abrasive) is recommended
for use on fiberglass finishes to remove scratches and stains or restore severely weathered
surfaces. These products can be applied by hand or mechanical means. The process below will
help restore fiberglass finishes:
•Clean the affected area with a good detergent.
•Remove stubborn stains or discoloration by gently wet sanding the affected areas with 600
grit “wet or dry” sandpaper. ALWAYS SAND IN ONE DIRECTION. Use plenty of
water and sand curves in the same direction. Dry the area to make sure all the discoloration
has been removed. Repeat this process if necessary.
•Buff using a polishing compound suitable for fiberglass, an electric buffer (1750-1800
RPM), and an 8-inch lamb’s wool pad.
C A U T I O N
!
Keep buffer moving. Do not allow it to rest in one spot. Heat build up will quickly distort the
surface.
C A U T I O N
!
Compounding too often or excessive compounding can wear away the gel-coat.
•When buffing is complete, wash away compound with clear water and dry the area.
•Once the area is clean it may be waxed. This will enhance the gloss while providing a seal
to retard staining or soil accumulation.
•See a local dealer for advice on wax for your boating region. The wax film will seal the
pores as well as enhance the looks of your boat. DO NOT wax surfaces that may bewalked on; they will become slippery. While waxing your boat, inspect the surface for
any damage. Have the damage corrected as soon as possible.

M AINTENANCEAND S ERVICE
Repairing
Though gel-coat is a very durable material, it is susceptible to scratches, blistering, and weblike cracking (crazing) over time. It is elastic enough to withstand strong blows while flexing
with the hull's movement. Gel-coat problems are cosmetic and will not effect the structural
integrity of your boat.
Some gel-coat damage and imperfections such as nicks and scratches can be repaired by
obtaining a color match patch kit. This kit can be purchased through your Grady-White dealer .
Acetone, the most suitable cleaning agent for gel-coat, can also be acquired through your
dealer. Instructions are included in the patch kit.
W A R N I N G
!
M.E.K.P. (Methyl ethyl ketone peroxide), gel-coat and acetone are flammable and hazardous
chemicals that must be handled properly. Follow instructions carefully. After the gel-coat is
catalyzed, it will soon heat up and put off fumes. When finished with catalyzed chemicals, or if
they start to build up heat, submerse completely in water until cool.
BOTTOM PAINT
If your boat is left in the water for more than a few days at a time, the hull bottom below the
waterline should be painted with anti-fouling paint to protect it from marine growth and barnacles
that hinder performance. Since anti-fouling paint slowly dissolves, yearly inspection and cleaning
of the hull bottom to prevent marine growth is advised. Repaint when necessary. To help prevent
blistering, use an epoxy barrier coat to be applied in conjunction with the anti-fouling paint.
CANVAS
Grady-White’s canvas is made using the highest quality vinyl and latest sewing techniques.
The canvas will not be completely leak proof. The seam holes in your canvas may stretch and tend
to leak. However, you can correct this problem by applying *Apseal® or Uniseal™ to the seams.
Please understand that Grady-White does not warrant the fit and design of the canvas to be
entirely watertight.
Maintenance
To maintain your boat's top and other canvas follow these guidelines:
Fabric should be cleaned regularly to prevent the buildup of soil and soil penetration of the
fabric. Simply brush off any loose dirt, hose down canvas and clean with a mild solution and
warm water . Do not use petroleum-based or ammonia cleaners on canvas or clear vinyl as they
will yellow. For heavily soiled fabric, remove the top from the frame. Soak the fabric in a
solution of 1/2 cup of Clorox™ and 1/4 cup of Ivory or Lux soap per gallon of warm water.
Let soak until mildew and stains can be brushed out with a common kitchen brush. Rinse
thoroughly with cold water until all soap is removed. Allow fabric to air dry completely. DO
NOT STEAM PRESS OR DRY IN AN ELECTRIC OR GAS DRYER. This will damage
the canvas fabric. Water repellent was applied to your canvas during manufacturing. The
repellent may have diminished after extended cleaning. Re-treatment of the fabric is
recommended. Do not use wax-based products. Use a water based repellent like *Apseal® or
Uniseal™. Scotchguard® is effective for short-term use only.

Snaps And Zippers
To protect the snaps and zippers on your boat’s canvas and cushions from corrosion and
binding, Grady White includes a snap/zipper assist tool and a tube of lubricant (E-Z Snap™)
in your owner’s packet. The lubricant, manufactured by IOSSO (part number 10909), should
be applied per the manufacturer’s directions during the initial use of your canvas and
cushions. The lubricant should be reapplied every 3 months or sooner depending on your
boating environment and usage. The snap/zipper assist tool included in your owner’s packet
should be used whenever you remove the canvas, cushions, or operate the zippers to prevent
damaging or tearing the material. Contact your dealer if you need to replace your assist tool or
reorder the lubricant.
Vinyl
•Clean clear vinyl thoroughly with denatured alcohol and apply a protective layer of clear
wax. Do not use paste wax, as it will turn the vinyl yellow. This process should be repeated
as necessary to maintain the protective wax coating.
•Store and secure canvas before trailering.
•Dry all canvas before storing to prevent mildew.
•Remove the top, front, and side panels. Roll them for storage. This is necessary to prevent
the front and side vinyl pieces from cracking. NEVER FOLD THESE PIECES!
Storage
Consider the following steps when putting your folding top canvas option in the stored
position:
•Fold the top and zip it into the canvas cover provided.
•Pivot the covered top into the stowed position on the foredeck. The canvas cover is
equipped with a strap on each side and an eyelet in each strap. Place the eyelets over the
male fasteners located on the port and starboard foredeck.
•Twist the male fastener 90 degrees to engage.

UPHOLSTERY
Your exterior vinyl upholstery may be cleaned with a mild solution of household detergent
and fresh water. Commercial cleaners for vinyl also work well. Since the seams of your exterior
upholstery are not waterproof, your upholstery should be stored in the cabin or covered when not
in use. Exterior cushions will trap moisture between themselves and the gel coat. If a cushion is
not removed to allow the moisture to dry, blistering of the gel coat may occur. Cockpit bolsters
may be removed if you desire. These bolsters clip onto brackets mounted to the deck structure.
Screws are then installed through the underside of the bolster to hold them in place. Most cabin
cushions are removable and may be dry-cleaned or steam cleaned. Some cabin cushions are of a
Herculon-type fabric and may be cleaned with upholstery cleaner.
C A U T I O N
!
Do not machine wash cabin fabrics.
DURATRIM/POLYETHYLENE/PLEXIGLASS/VINYL
In the cockpit area of your boat, duratrim, plexiglass, and vinyl are used for trim and
polyethylene is used for the toe rails and rod racks. Routine maintenance for duratrim and vinyl
should include regular cleaning with soapy water and the application of a surface protector at least
twice per year. Polyethylene can be cleaned with products such as 409 or any spray and wipe
cleaner. Plexiglass, used to cover your instruments’ radio box and also as interior storage doors,
can be maintained by use of a glass cleaner and a soft cloth.
SCUPPERS
Grady-White boats have self-bailing cockpits meaning water on the cockpit floor drains by
gravity through large aft scuppers and not into the bilge. The aft drains (scuppers) have an
external scupper flap assembly that restricts the flow of water back into the boat. Inspect the flaps
periodically to make sure they are free of debris. The scupper flaps may need periodic
replacement if the rubber becomes damaged or no longer seals properly in the thru-hull.
CAULKING/GASKET
Deck fittings, bow rails, windows, hatches, etc. have been caulked or gasketed with the
highest quality material to ensure a waterproof joint with the boat. However, the working action
of normal use will tend to flex the joint and eventually break down the seal between them.
Periodically inspect the caulking or gaskets for leaks. Recaulk or replace the gaskets necessary, or
have your dealer do the repair.
HARDWARE/HARDTOP FRAME/STAINL ES S STEEL RAILS
The hardware on your Grady-White is made of laboratory grade 316 stainless steel and needs
regular cleaning to maintain its “less staining” properties. The key to maintaining your stainless
steel is to keep it clean with a mild solution of soap and FRESH water. Remove salt or dirt from
your stainless steel on a regular basis.
6–5
M AINTENANCEAND SERVICE
HARDWARE MOUNTING
Ensure all holes are sealed properly when mounting hardware in the boat surface. Sealing will
prevent water leakage. This is crucial in fiberglass areas that have been reinforced with plywood.
A hole sealed improperly allows water inside the fiberglass leading to saturation of the plywood
reinforcement.
MAINTENANCE PROCEDURE FOR ANODIZED ALUMINUM COMPONENTS
(Lean Bars, Rod Holders, T-Top and Hardtop Frames, Outriggers, Etc.)
Due to the nature of anodized aluminum and the harsh exposure conditions of the marine
environment, it is important to follow a required maintenance procedure. Failure to follow a
preventative maintenance procedure will most likely result in aluminum pitting.
These parts must be washed periodically with a very mild soap and water solution. Grady
White recommends washing with a mild soap (such as Ivory Liquid) after each use and every two
to three weeks if stored in an outside marine environment. Strong cleaners and soaps must not be
used. Never use abrasive cleaners or products that contain chlorine bleach. These products can
remove the anodized coating.
Give special attention to the upper tubes of a hardtop or T-top frame. The area just below the
top is shielded by the canvas or fiberglass top and does not receive the natural rinse that rainwater
provides. Failure to thoroughly clean and maintain this area will allow contaminates that attack
the anodized aluminum to remain on the frame.
For maximum protection, coat parts with a non-abrasive metal protector. The best protectors
will displace moisture, remove contaminates, and leave a wax film protecting the anodized
aluminum. Follow the application guidelines for the product you choose. A sample of one metal
protector has been provided with your boat.

FUEL SYSTEM MAINTENANCE
To determine whether a fuel flow problem is in your fuel system or your engine, follow this
simple method. Connect a six-gallon portable tank to the engine and operate the engine. If the
problem persists, the likely cause is with the engine itself. If the problem goes away, the source
must be in the boats’ fuel system. One component that should be inspected if a restriction occurs
is the anti-siphon valve. If fuel does not flow properly through this part, it must be cleaned and/or
replaced. DO NOT remove the anti-siphon valve and replace it with a regular barb.
6–6
M AINTENANCEAND S ERVICE
Annually conduct a detailed inspection of fuel system components, especially those hidden
from routine inspection. Replace any fittings, deteriorated hoses, clamps or connections
immediately. Fuel filter/water separators should be replaced at least annually.
FUEL TANK COMPARTMENT
The fuel tank compartments need to be rinsed periodically especially when used in a saltwater environment. Dirt accumulation attracts salt, creating salt crystals. Salt crystals can corrode
most metal surfaces if left untreated over a period of time. T o help protect your fuel tank from rust
and corrosion, rinse the compartment with FRESH water. After rinsing, make sure all water is
drained from the compartments. Remove the access plates from fuel tank lids and inspect this area
for leaks or unsecured lines.
The access plates on your fuel tank lids keep the fuel compartments sealed. Over time, the
opening and closing of these plates causes the o-rings to wear-out. Replace these o-rings as
necessary to maintain the watertight integrity of the plates.
SHOWER SUMP
A shower in the head compartment drains into a contained “sump” which is used to prevent
hair, soap, scum and bacteria from accumulating in the bilge and creating odors. This sump
should be cleaned regularly. The sump pump box contains a filter. Remove the filter and rinse
with water to clean. The filter should always be installed when using the shower to prevent the
sump pump from becoming clogged.
BATTERIES
Proper battery power is essential to the operation of your vessel. For this reason, Grady-White
has carefully chosen a battery with cranking ability and reserve capacity sufficient to meet your
needs. The factory installed Deka Marine Master 27M6 battery is a maintenance free battery . This
battery utilizes an exclusive demineralized electrolyte and maintenance free calcium alloy grids.
These features reduce water loss and extend the life of the battery. However, this battery is
maintenance accessible in the unlikely event a charging malfunction occurs. Grady-White
recommends the Deka 27M6 product for all replacement applications. If your boat is equipped
with batteries not installed at the factory, consult with the battery manufacturer for proper care
and maintenance instructions and the engine manufacturer for appropriate battery specifications.
Batteries must be secured in a non-metallic tray to contain electrolyte spills. An insulated boot
should cover battery terminals. Keep terminals clean by scrubbing them with a stiff brush and a
mixture of baking soda and water. Afterwards, apply a light coat of grease or corrosion
preventative.
Batteries contain sulfuric acid, a harmful and potentially volatile chemical. When handling
batteries, exercise caution and follow these guidelines.
• Avoid contact between skin, eyes, or clothing and sulfuric acid.
• Protective gloves, eye wear, and clothing should be worn when servicing to
minimize risk to yourself.
• Batteries produce explosive gases. Keep sparks, flames and cigarettes away.
Ventilate when charging or using in an enclosed space.
• Keep out of reach of children
6–7
M AINTENANCEAND SERVICE
This is not a complete set of guidelines. It is your responsibility to safely maintain your
batteries and avoid injury. Use good judgement and remain alert to prevent an accident. In the
event of an accident or exposure to electrolyte, immediately seek prompt medical advice or
attention.
W A R N I N G
!
Do not allow any electrically conductive material to make contact with both the positive and
negative terminals at the same time (i.e. a hand tool used when disconnecting and reconnecting
battery cables). A short of this nature can cause severe burns and create dangerous sparks which
could result in personal injury and/or property damage.
C A U T I O N
!
When disconnecting and reconnecting battery cables, the black cable must be connected to the
negative terminal and the red cable must be connected to the positive terminal. Reversing these
connections will immediately damage your system.
Never disconnect the battery when the engine is running. This can cause damage to the charging
system. When replacing your battery , use the same brand and type as the factory installed battery.

Chapter 7: Winterization and Storage
GENERAL
Boats stored during the winter or for an extended period of time require some routine
maintenance. The boat and its systems should be checked for maintenance and repairs prior to and
during the storage process. Arrange repairs during the storage period to reduce downtime during
your boating season.
Avoid costly damage and delay when launching your boat by having it stored and winterized
properly. This information is presented as a general guide; the actual storage should be performed
by a professional and qualified dealership. See page 61, in Sportfish, Cruisers, Yachts Owner ’sManual for a checklist on winterizing and storage.
BOAT STORAGE
Grady-White boats are equipped with stern eyes and a bow eye. These eyes are for anchoring
and trailering purposes, and should be inspected regularly to insure structural integrity.
W A R N I N G
!
The boat should not be lifted for storage using the bow and stern eyes.
STo avoid personal injury and pr operty damage, it is advised to take extra precautions when
lifting or moving the boat for storage.
While transporting a boat by a lift or fork lift, the structure should remain as close to ground
level as possible. If slings are necessary for lifting or transporting, they should be in proper
condition and tied together to prevent any movement (separating or slipping) which could cause
damage to the boat. If fork lifts are used to move the boat, the forks should be padded, contoured
to match the hull bottom, and in a secure location under the hull in alignment with the stringers.
The forks should be long enough to prevent the boat from rocking forward and aft causing it to
become unbalanced. Always verify the fork lift’s capacity to ensure it is sufficient for the weight
of the boat. Other conditions that should be considered before hauling, transporting, or storing
your boat include overhead lines, ground conditions (frozen or soft), and storm conditions that
may arise.
When storing your boat on the trailer, raise and block the trailer axle to prevent tire
deterioration. This is an excellent time to lubricate and pack the wheel bearings per the
manufacturer’s instructions.
Make sure the keel, chines and transom are fully supported. Indoor storage is beneficial
particularly if your climate produces freezing weather. The storage unit should not be airtight, but
should be ventilated. Ventilation is extremely important both around and through the boat.
7–1
W INTERIZATIONAND STORAGE
For outdoor storage, a canvas cover should be used to prevent “sweating”. One method is to
build a frame over the boat to support the canvas. It should be a few inches wider than the boat so
the canvas will clear the rails and allow passage of air. The cover should be fastened securely so
that winds cannot remove it or cause it to chafe the boat. A poor covering job will eventually cost
more than the price of a well-made cover.
W A R N I N G
!
Boats covered with plastic shrink wrap during storage must leave the fuel fill and vent fitting
outside of the enclosure to prevent the trapping of dangerous fumes or spillage from thermal
expansion.
CLEANING AND LUBRICATING THE BOAT
Clean and wax your boat before storage. If you store your boat in the water, there may be a
layer of growth on the bottom. As it dries, this debris will harden. Clean, scrub and scrape the
bottom promptly when the boat is removed from the water. Remove all marine growth and other
foreign matter from the hull. Clean the inside of hull openings, thru-hull fittings and scupper
drains. Inspect the hull for damage. Remember to avoid harsh cleaners, citrus solutions and
bleaches; these could have harmful effects on your boat’s gel-coat and metal components.
Check cleats and rails for corrosion and tightness. Clean stainless steel as directed under
“Hardware/Hardtop Frame/Stainless Steel Rails” on page 6–5. Use a quality metal preservative
like T-9™ on metal surfaces to prevent salt-water damage. Check for loose silicone, hinges and
unseated gaskets. Replace or tighten where necessary. Heavy seas pounding and twisting the hull
can cause leaks in your windows, doors and hatches. Check hinges for corrosion. Lubricate hinges
as necessary.
The T-9™ metal protection product was developed by Boeing™ Aviation for long-term protection of aircraft. It works
by coating and penetrating fasteners and fixtures, displacing moisture and drying to a clear wax film that lubricates
and protects metals for months. T-9 can be used to protect deck hardware, engines, electronics, and fishing tackle.
DRAINING & WATER SYSTEM
If the boat is stored out of water, remove the garboard drain plug to keep the bilge dry. Store
your boat with the bow elevated for drainage.
Drain all water tanks, hoses, filters and pumps to prevent freeze damage. The fresh water
system may be drained by running any faucet until the tank is empty. When empty, turn the water
pump off to prevent damage. Remove the filter on the freshwater pump inlet, remove any water
and reinstall. Residual water will not damage the tank. If desired, the fresh water system may have
a non-toxic antifreeze for potable water systems added. To drain other systems, close seacocks
and run the pumps until the lines are dry. Open the seacocks after lines are dry. Draining will help
prevent water stagnation in warmer climates.
HEAD SYSTEM
Empty toilet and holding tank making sure all water is cleared. Reference Owner’s Packet for
manufacturer’s information on winterization. Water should be removed from deck pump-out
hoses.

W INTERIZATIONAND S TORAGE
BATTERIES
Fully charge the battery before storing. A weak battery loses its charge more rapidly than a
strong battery. Ideally, you should disconnect the battery and cover the terminals with grease to
prevent corrosion.
ENGINES
See your engine Operator’s Manual regarding the winterizing procedures. Follow instructions
carefully, and your engine will withstand severe weather conditions. Change all filters. Check
hoses and clamps. If you have developed any vibrations during the season, look for loose engine
bolts, bent shafts or bent propellers.
FUEL SYSTEM
The fuel systems should be winterized by following the fuel system maintenance and fuel tank
compartment instructions in the maintenance and service section.Ta nks should be kept filled
when the boat is not in use to reduce the accumulation of moisture and condensation. Add
stabilizer to fuel that won’t be used in 60-90 days. .

corrosion that could lead to an electrical system failure.
AUXILIARY FUSE PANEL
The auxiliary fuse panel located inside the upper console rigging compartment provides a
source of power for electronics in addition to the accessory switches and breakers. Your model
utilizes the automotive type fuse.
8–3
306 BIMINI
MAIN CIRCUIT BREAKER
There is a 50 amp circuit breaker located in the panel beneath the battery select switches. This
breaker is the main protection for the wiring supplying power to the accessory switch panel and
helm fuse block. If this breaker is tripped, depress the red button on the breaker box to reset it.
ACCESSORY OUTLET - 12 VOLT
The two 12-volt outlets on either side of the control cable chase on the console provide easily
accessible power supplies for accessories such as cellular phones and spotlights.
N O T I C E
These outlets cannot be used with a cigarette lighter.
COMPASS
The compass is located at the helm in direct view of the operator when navigating the boat.
Compensation adjustments may be made by following the instructions provided in the “Owners
Packet”.
AFT RIGGING COMPARTMENT
The rigging compartment is located aft of the fuel tank compartment. This area is functional
for rigging ignition protected accessories and for better access to the rigging components located
aft of this compartment. This compartment contains two flats in the hull bottom for mounting
transducers.
N O T I C E
The rigging hatch and mounting screws must be sealed with silicone sealer after rigging is
complete. When the lid is removed, it must be resealed to insure watertight integrity.
BILGE PUMP WITH FLOAT SWITCH
Your boat is equipped with automatic float switches adjacent to the bilge pumps. A float
switch will enable the bilge pump to come on automatically if a significant amount of water
accumulates in the bilge. These switches are wired directly to the batteries. They function
independently of the battery select switches and can activate the bilge pump with the battery
select switches in the “off” position. Batteries should be inspected frequently to ensure proper
operation. The bilge pumps are also equipped with switches at the helm. When a switch is in the
“off” position, the pump is off unless activated by the float switch.
C A U T I O N
!
To prevent damage to the bilge pump, do not run it dry for a prolonged period of time.
BILGE PUMP LOCATION
There are two bilge pumps on the 306 Bimini. One is located under the motorwell access plate
forward of the transom. The other is located under the rectangular access plate in the lower
console rigging area.
8–4
306 BIMINI
SHOWER SUMP PUMP
The shower sump pump pumps water from the shower floor overboard. The console sink also
drains to this pump. This unit is located under the rectangular access plate in the lower console
rigging area.
COCKPIT SHOWER
To operate the cockpit shower, the water pressure switch located on the switch panel must be
in the “on” position. Open the cover and pull the shower wand out from the recessed deck fitting.
Depress the button on the back of the wand to spray water. To reinstall the shower wand into the
recessed fitting, gently feed the hose down through the deck and replace the cover on the deck
fitting. The fresh water capacity is 32 gallons. The water pressure pump is located in the lower
console rigging area. See “Freshwater System” on page 8–18 for a layout diagram.
CONSOLE FRESH WATER
The console fresh water system is pressurized by the water pressure switch located on the
switch panel. After turning this switch to the “on” position, the console faucet water flow can be
controlled by the using its flow control knob. When needed, you can pull the fixture out from its
recessed fitting to be used as a shower. To reinstall, gently feed the hose back down through lean
bar. See “Freshwater System” on page 8–18 for a layout diagram.
LEANBAR FRESH WATER
To operate the lean bar fresh water system, the water pressure switch located on the switch
panel must be in the “on” position. Control the water flow by depressing the lever on the back of
the wand. Pull up on the lever to lock for continuous use. When needed, you can pull the fixture
out from its recessed fitting to be used as a shower. To reinstall, gently feed the hose back down
through lean bar. See “Freshwater System” on page 8–18 for a layout diagram.
WINDSHIELD WASHER SWITCH
A valve located in the forward wall of the deckwing controls your windshield washer. Water
will be sprayed on the windshield, by opening this valve with the Fresh Water System pressurized.
To pressurize, locate the water pressure switch on your boat’s DC panel, and place it in the “on”
position.
TRANSDUCER FLATS
The inverted transducer flats are designed primarily for a bronze style torpedo-shaped
transducer. An example of a torpedo shaped unit would be an Aero Mar Tri-Transducer. This
transducer is approximately ¾” thick. This thickness allows the transducer face to protrude below
the bottom of the hull. An additional ½” spacer may be installed between the hull bottom and the
transducer for optimum results. The transducer should be installed as far forward on the flat as
possible, and parallel with the keel.
N O T I C E
A flush mount style transducer will not work with the inverted flat.
8–5
306 BIMINI
SEACOCKS
Ball valve seacocks are installed on the inlet thru hulls for the livewell and washdown
systems, and on the inlet and discharge thru hulls for the head system. It is necessary for the
seacocks to be in the open position to operate the systems. The open position is identified by the
orientation of the handle. If the handle is in line or parallel to the body of the valve, the seacock is
in the open position. If the handle is perpendicular to the body of the valve, the seacock is in the
closed position. Remote arms are installed on the seacocks. The open position can be obtained by
pulling up on the remote arm attached to the seacock handles. Pushing down on the remote arm
closes the seacock.
N O T I C E
All seacocks should be in the closed position if not in use or if the boat is left unattended to prevent
water from entering the boat if a plumbing component fails.
LIVEWELL - RAW WATER
To operate the livewell, open the seacock located in the port aft rigging area using the remote
arm labeled livewell. The livewell pump is screwed directly into this seacock. The livewell switch
at the helm should be in the "on" position. Place the livewell standpipe in the drain located at the
bottom of the livewell. Screw it down until the black flange makes contact with the flange on the
drain fitting. Water will enter through a plenum along the side of the livewell and be distributed
through a series of holes arranged vertically along the plenum. The water will rise to a depth even
with the strainer on the standpipe and drain overboard. The shut-off valve attached to the thru hull
drain must be open for the livewell to drain. This shut-off valve can be accessed through the 6”
access plate located at midship on the port side. To evacuate debris and bait waste from the
bottom of the box while the livewell is in operation, unscrew the standpipe approximately three
turns to expose two 3/8” holes located in the threads of the standpipe base. This will allow a small
amount of water to escape through these holes and remove any waste that has settled in the
bottom of the livewell. See “Livewell/Washdown System Layout” on page 16 for a layout
diagram.
N O T I C E
If the livewell seacock is left open and the pump is not on, the boats forward motion through the
water will gradually fill the box. To prevent this inadvertent filling, close the seacock when the
livewell is not in use.
Under certain conditions, placing the outboard engine(s) in reverse will ventilate the water under
the boat and create an air lock in the livewell pump. To prevent this situation from occurring, it is
recommended the livewell be turned off prior to any high RPM or continuous reverse operation.
If the livewell pump becomes air-locked, correct this situation by turning the pump off for 20
seconds.
8–6
306 BIMINI
WASHDOWN OPERATION
T o operate either washdown, open the seacock located on starboard side of the aft rigging area
using the remote arm labeled washdown. Depress the washdown switch on the accessory switch
panel. This system will now be pressurized at the forward washdown faucet outlet and the
hosecoil unit located in the lean bar . The forward faucet may be used alone or with a hose. A hose
with a spray nozzle attached at the forward outlet or the hosecoil unit may be used intermittently
without turning the switch off in the same fashion as a home yard hose with a nozzle. The
washdown pump has an internal pressurization switch that will maintain water pressure as needed
until the switch is turned off at the switch panel. The pump is mounted in the aft rigging area
beneath the aft rigging lid. An in-line strainer on the pump intake is mounted near the pump and
should be inspected and cleaned at least annually.
See “Livewell/Washdown System” on page 8–17 for a system diagram.
BATTERY SELECT SWITCHES
The 306 Bimini is equipped with three batteries and two select switches. Two of the batteries
are wired in parallel and function as a single battery bank (“1” on the switches). The third battery
is a separate bank (“2” on the switches). See “Battery W iring With Select Switches” on page 8–23
for a wiring diagram.
An outboard engine should be connected to each battery select switch. Either engine may be
started with either battery bank by selecting position “1” or position “2” on the select switches. In
normal use, select position “1” on the starboard switch and position “2” on the port switch so that
both battery banks will be charged simultaneously when the engines are running. The DC
accessories on the boat will always be controlled by the starboard switch. This recommended
setting also insures that the accessories are being powered by the larger battery bank.
C A U T I O N
!
Never turn the battery select switches to the “OFF” position with the engine running since this
could damage the charging system.
8–7
306 BIMINI
TRIM TABS
Trim tabs are electrically and hydraulically operated. The trim tab system consist of a
hydraulic pump, a two-rocker switch panel, a trim tab position indicator panel, and an auto-retract
device. The rocker switch controls the pump which lowers and raises the trim tabs. The indicator
panel keeps you constantly aware of the trim tab’s position. The auto-retract device causes the
pump to raise the tabs every time the ignition switch is turned off
Trim tabs are used to regulate the attitude of the boat while moving. They are operated by a
two-rocker switch panel and will aid in trimming the boat fore and aft for a smoother ride. Tr im
tabs can improve the ride of your boat by adjusting where the water is hitting the keel line. In a
slight chop, the waves may be hitting the keel of your boat around the helm area causing an
uncomfortable ride. By adjusting the trim tabs and lowering the bow, the waves will hit the keel at
a more forward point and soften the ride. Experimenting with trim tabs in various sea conditions
will help you determine the best positions for your boat under different load conditions.
Trim tabs are also useful in correcting a port or starboard running list. If the boat is listing to
the port side, press the starboard trim tab switch toward “bow down”. Press the port trim tab
switch toward “bow down” to correct a starboard list. This will tend to lower the bow by pulling
the higher side to a level position. If your bow is already in a low position, you may correct a
listing condition by pressing the trim tab switch toward “bow up”. This will cause the low side to
rise and level the boat. The running angle will also gradually improve.
The switches are marked “bow down” only. Trim tabs in the extreme “bow up” positions will
have no effect on the boat's ride. Trim tabs in the extreme “bow down” position will cause the
boat to come on plane with minimum bow rise. Unless you are operating at low speeds or with
considerable cockpit weight you will likely want to raise the tabs slightly when underway to avoid
“plowing” water. With the tabs in the “bow down” position, you will be able to maintain a plane at
the least possible RPMs.
N O T I C E
Most drive units are equipped with an adjustable rudder trim tab. This trim tab should be
adjusted to balance the steering at the speed which you travel most frequently. Variations in
speed, boat load, or changes in the drive unit trim will cause the steering to pull in one direction. If
the boat pulls to the left, adjust the trim tab to the left and vice versa.
Trim Tab Pump Location
The trim tab pump is located in the console lower aft rigging compartment.

306 BIMINI
Operation Of Optional Features
BOW THRUSTER
The optional bow thruster aids in maneuvering your boat. The outboard engines can control
the direction of the stern while the bow thruster moves the bow side to side. Use the joystick
control located at the helm to control the thruster. The emergency shut-off switch, located below
the binnacle controls and to the starboard side, provides a simple method to quickly disconnect
power from the thruster motor. Depress this button to disengage the thruster in the event of an
emergency.
DOCKSIDE POWER
The dockside power feature provides AC current to the battery charger located in the console
rigging area. This is a dedicated system, supplying power only to the battery charger. It does not
supply current to any other panels or devices on your boat The dockside power is used by
connecting the heavy duty cable supplied with the boat to an appropriate external power source.
This cable provides power to the boat’s AC inlet which is routed directly to the battery charger.
See “Dockside Power” on page 8–28 for more information on component location and wiring
specifics.
C A U T I O N
!
Always disconnect the dockside power cable if leaving the boat unattended for an extended period
of time.
Connecting The Dockside Power
1. Verify that the external power source is a 3 wire grounded system with amperage and
voltage ratings compatible with the boat’s AC system ratings.
2. Be sure there is sufficient cable length to allow for normal movement between the boat and

306 BIMINI
Battery Charger (Dockside Power Option)
The dockside power must be connected for the charger to work. See “Dockside Power” on
page 8–10 for instructions. The charger is located in the upper rigging compartment inside the
console. It can be accessed through the upper rigging door on the aft head wall. To activate the
charger, turn the breaker switch located under the aft starboard gunwale to the "on" position.
The charger has a built-in isolator which senses the charging needs of all the batteries and
distributes charge accordingly. At the point that all batteries are nearly fully charged, the
charger will automatically reduce the current being sent to the batteries to a maintenance
level. See the Operation Manual for further information.
T-TOP
If your boat is equipped with a T-top, do not use the top for storing heavy or large items such
as a raft. The frame for the top is designed for continual use with antennas, radar, and outriggers.
The additional weight caused by larger items such as a raft may cause damage to the frame
structure.
OUTRIGGERS
The optional outriggers allow you to spread the fishing lines trolled from your boat and
decrease the chance of entanglement.
• Advantages
Advantages of outriggers include: offering bait throughout a larger area behind the boat,
placing bait out of the wake zone, automatic drop back following strikes (which allows for
fish to completely accept bait), and a reduction in unnecessary twisting action characteristic of
artificial bait.
• Instructions
For proper installation and use, refer to the instruction sheet included in your Owner’s Packet.
• Care And Maintenance
- Outriggers should be washed with fresh water, mild soap, and a soft cloth. The poles should
be sprayed down with fresh water. Never use acidic or abrasive cleaners to clean your outriggers.
- A periodic waxing of the outriggers is suggested if your boat is frequently exposed to salt
water. The wax will provide a protective coati ng and seal the pores of the metal. A non-abrasive high quality marine or automotive wax is recommended. Clean and wax your outriggers before storage.
- During assembly grease all threads, bolts, and tubes where one section is inserted into
another. Annually disassemble and regrease all applicable surfaces.
8–11
306 BIMINI
POWER ASSIST HYDRAULIC STEERING
The engine ignition switches must be on for this system to function. The power assist
hydraulic pump in activated simply by turning the steering wheel. The hydraulic pump senses the
motion of the hydraulic fluid from the helm and pumps fluid in the cylinders at the engine
accordingly. The power assist pump is installed in the console rigging compartment and can be
accessed via the access panel in the aft console wall. Over-current protection is provided by a 40A
fuse located near the battery. This system is compatible with multiple steering stations and the use
of an autopilot. Refer to the owner’s manual in your owner’s packet for more information.
STEREO
The stereo is a marine Sirius ready AM/FM receiver with CD player. It is located inside the
console with speakers in the cockpit. The unit can be remotely operated with the touch pad
mounted at the helm station. An auxiliary audio input panel is also part of the stereo system. This
panel may be used to listen to any external audio device (such as an mp3 player) using either
standard RCA cables or an 1/8” cable. Refer to the stereo’ s Operation and Maintenance manual in
your Owner’s Packet for specific instructions on using this unit. See “Stereo Layout and Wiringwithout Factory T-top” on page 8–26 for a layout diagram.
SIRIUS SATELLITE RADIO
The Sirius satellite radio includes the Sirius satellite tuner and antenna which provides access
to many channels of digital entertainment. The antenna is installed on the forward bow area away
from any structure that may cause signal interference. The tuner is installed inside the console
rigging area beneath the stereo. The tuner is controlled by the Sirius ready stereo installed on your
boat.
You may activate your subscription to Sirius online at siriusradio.com or by calling toll-free 1888-539-SIRIUS. If you choose to call, a Sirius operator will walk you through the initial setup
process. You will need the ESN number for your tuner, a major credit card, your boat in a location
where the antenna is not blocked from receiving signal, and the Sirius tuner tuned to channel 184.
You will find the ESN number attached to the warranty card for the tuner included in the owner’s
packet. You may also obtain this number using your Sirius ready stereo by following a few simple
steps:
1. Press the TU/SR button repeatedly until “SIRIUS” appears.
2. Hold the MENU button until “MENU” appears.
