History
In 1958, company founder Richard T. Fisher introduced the first Boston Whaler boat in Braintree, Massachussetts. It
featured two significant innovations: first, its twin sponson hull design produced superior stability and a remarkably dry
ride; second, its unique foam core construction made the boat not only durable, but unsinkable as well. Fisher took every
opportunity to illustrate the unique characteristics of the BostonWhaler. His most famous demonstration was captured in
1961, by Life Magazine. The series of photographs showed the boat underway, the boat being sawed in half and ulti-
mately Fisher motoring away in the remaining half of the boat. And through the years many other demonstrations have
proved the toughness and durability of the BostonWhaler hull.And though you may never cut your boat in half, this only
goes to show one thing, people whose livelihood and lives depend on boats consistently choose Boston Whaler because
of their seaworthiness, dependablility and the inherent safety of a hull that won’t sink even if severely damaged. Boston
Whalers are built to last. For over 40 years Boston Whaler® has strived to make each model better, providing you with
a safe and fun boating experience. That is the reason we offer a 10 year limited transferable warranty. It is also an
excellent reason why you can trust the safety of your family and friends to a Boston Whaler.
PLEASE KEEP THIS BOOK AND OTHER MATERIALS IN A SECURE PLACE, AND BE SURE TO HAND IT
OVER TO THE NEW OWNER IF YOU SELL THE BOAT.
This Owner’s Manual has been written to provide specific information about your boat and it should be read carefully.
Keep this booklet in the Owner’s Manual Packet. The Owner’s Manual Packet has been compiled to help you operate
your boat with safety and pleasure. It contains details of the boat, the equipment supplied or fitted, it’s systems and
information on it’s operation and maintenance. Please familiarize yourself with the boat and it’s operation before
using it. If this is your first boat, or you are changing to a type of boat you are not familiar with, for your own comfort
and safety, please ensure that you obtain handling and operating experience before “assuming command” of your
boat.Your Boston Whaler® dealer or localYacht Club will be pleased to advise you of marine safety classes and safe
boating classes in your area.

Hull Identifcation Number
The “Hull Identification Number” is located on the
starboard side of the transom wall.
Thisis themost importantidentifying factor andmust
beincluded in allcorrespondence related toyour ves-
sel. Failure to do so will only create delays.Also of
vital importance are the engine serial numbers and
part numbers when writing about or ordering parts
for your engine.
Our Hull
Boston Whaler® hulls are constructed with our pat-
ented Unibond™ construction. This involves shoot-
ing high density foam into a closed mold system.
The foam expands to fill voids in the hull, and when
thefinished product is pulledfrom the mold, thedeck
and the hull are chemically bonded to form a solid,
inseparable unit.

Tank Selection
There are a pair of 3-way gasoline valves that con-
trol the flow of fuel to the engines. The fuel system
is designed to have the port engine supplied by the
port fuel tank and the starboard engine by the star-
board tank. The valves can be used so both engines
can be supplied by either tank. (If both engines will
be run from one fuel tank, the boat will eventually
list to the opposite side of the tank being used). The
valves have PORT, STARBOARD, OFF clearly
markedon the perimeterof eachvalve.Turnthe valve
handles to the desired position for the appropriate
tank. Be sure to always check the level of each fuel
tank and position of fuel valves to prevent the boat
frombecoming unbalancedwhile underway.Thetank
selector gasoline valves are located on the aft wall
of the stern foldaway seat.

Primer Bulb (Optional)
If equipped, a pair of primer bulbs can be accessed
under the port and starboard sides of the motorwell
hatch. The primer bulbs are used to draw fuel from
the tank to the engine, usually after the fuel has been
drained from the entire system. There are also in-
structions regarding proper use of the primer bulb in
the engine manufacturers handbook.

The fuel tank(s) have a fuel tank vents located
amidship, 7-9” inches below the rub rail directly be-
low the fuel fill cap. The fuel tank vent serves as a
pressure/vacuum release, safety overflow and flame
arrestor. Access to the vent fittings is through twist-
out plate located inside the cockpit opposite the fuel
tank vent. Check the vent assembly regularily as part
of a maintenance schedule for continued safe opera-
tion of your boats fuel system. The Vent assembly
consists of a backshell, starwasher,nut and hose
clamp. Remove the hose clamp, nut, starwasher and
backshell and push the fuel vent fitting out. The fuel
vent has four screens that are held in by a ring. Use a
small pick to dislodge the ring to remove the screens
and clean as required.

320 Outrage-Owner’s Manual
EMPTY TANK:
A fuel tank with levels less than 1/4 full can cause
problems by stalling an engine due to fuel starvation
or by allowing sediment and dirt to enter the fuel
supply lines. Keeping the tank filled will reduce the
chance of this occurance; since the residue will most
likely settle to the bottom of the tank. Monitor the
fuel level often to prevent this from happening.
HOSES AND FITTINGS:
Hoses and fittings should be inspected at least every
100 hours. Check the hoses for cracks, abrasions and
deterioration and the strong smell of fuel prior to
startingthe engine(s). If thehoses or fittings aredam-
aged or worn, replace them with only marine grade
replacement parts. Your authorized BostonWhaler®
dealer will have all the parts information you will
need.
TANK CLEANING:
Excessive water and sediment may force you to con-
sider having the tank professionally cleaned. If you

Remote Oil Tank Location
(sterndeck has been removed)
Optional engine oil supply, 2-3 Gal. (11.3L)
The 320 Outrage may be equipped with a remote oil
system. This system consists of two 3-Gal.(11.3L)
reservoir tanks and hoses which contain and meter
lubricating oil to the engine(s). The tanks have an
externalfill located on the aftside of the cockpittran-
som wall. Access to the tanks is through the
motorwell access hatch. When recapping the fill
make sure that it is secure to prevent spills and to
prevent the intrusion of water into the system. Your
remote oil tank is secured by a nylon strap and quick
release clip. Little maintenance is required for the
remote oil system, aside from checking the hoses for
abrasions and cracks and hose clamps for proper
tightness. The tank should not be exposed to ultra-
violet light, rain or seawater for extended periods of
time.

• Fuel tanks should never be filled to capacity. al-
low 2% for expansion.
• Portable tanks should only be filled while on the
ground; never on-board the boat.
Thereis adanger thatstatic electricitycan ignitegaso-
line vapors that have not been ventilated outside an
enclosed area. Use extreme caution when fueling
your boat from a source outside the regular venues,
(e.g. marinas, fuel service stations.)
Your boat has safety features that can be circum-
vented by not adhering to standard fueling practices.
Your boats bonding system protects it from creating
and discharging static electricity.
Your boat must be in contact with the water or a land
based grounding system. Here are some helpful sug-
gestions to keep you safe from static electricity while
refueling your boat.
• NEVER fuel your boat in unsafe conditions such
as: suspended on a sling or in a situation that in-
creases the likelihood of static discharge.
• NEVER use homemade containers to fill your fuel
tanks.
• Fuel carried on-board outside of a fixed fuel sys-
tem should be stored in an approved container or
in a portable tank such as provided for outboard
engines and be stowed safely outside of the engine
or living compartment(s).
• Shut down the engine(s), motors and fans prior to
taking on fuel.Any ignition sources should be ex-
tinguished before filling the fuel tank(s).
• Close all ports, windows, doors and hatches.
• Fueling should never be done at night except in
well-lighted areas.
• Always keep the fuel nozzle in contact with the
fuel fill plate or the edge of the fuel tank opening
throughout the filling process.
• Allow areas where gasoline vapors could collect
to be ventilated before starting the engine(s).
• Wipe any spillage completely and dispose of rags
or waste on shore.
• Secure the fill cap tightly.

DC Electrical System
Battery Information
Your 320 Outrage is equipped with
a Direct Current (DC) electrical sys-
tem. All power to the boats systems
are provided by the batteries. The
batteriesare continuouslychargedby
the engines alternator while the engines are running.
The following are powered directly from the batter-
ies.
• Engine ignition
• Engine tilt trim system
• Helm switch panel & helm instrument panel
• Lighting/Navigation system
• Livewell system
• Add-on accessories and electronics
The system consists of the following components:
• Battery boxes, (3 standard)
• Battery switches
• Main & Branch circuit breakers
• Helm Ignition, Switch & Instrument Panel
BATTERY
-+
Batteries should always be enclosed in the covered
battery boxes provided with your boat. The box will
contain any spilled acid, as well as protect the bat-
tery terminals from damage or inadvertant shorting
from coming in contact with metal objects. Each bat-
tery box should always be secured in place by using
the straps and clamps provided, the straps will en-
sure that while underway the battery will not move
around, causing damage to components stored in the
same area.
BATTERY BOX LOCATION:
The3 standard batteryboxes can beaccessedthrough
a door in the aft section of the console interior.

Battery Maintenance
Battery maintenance should include:
• Inspect each battery and charging system before
use; for loose connections or wiring.
• If not using a sealed battery, check & maintain
the water level. USE distilled water ONLY.
• Coat the terminals with dielectric grease.
• Keep the batteries dry.
• Remove the batteries from the boat during cold
weather or long term storage.
The most life shortening experience for the battery
is to be drained to zero charge before recharging.

Your 320 Outrage uses a battery selector switch to
controldelivery of DC powerfrom two batteries.The
battery switches are located below the breaker panel
on the aft bulkhead inside the console.
The dual battery switches have four (4) settings:
• “OFF”, you will have no power to the engine(s).
• “ALL”, you will have power from both batteries
at the same time. This parallels the batteries to
assist you in starting the engine(s), once the en-
gine is started the battery switch should be taken
off of the “ALL” setting, and set to charge either
battery .
• “1”,youwillhavepowerfromthe portbatteryonly.
• “2”, you will have power from the starboard
batteries only.
When the engines are shut down or not providing a
charge,the systemwill drawpowerfromthestarboard
batteries.Thiswill allow youto run allthe boatsfunc-
tions without affecting the port battery. You can run
thestarboard batteriesdown and still startthe engines
by moving the selector knob on the battery switches
to the “ALL” position. The battery switches are lo-
cated below the breaker panel on the aft bulkhead in-
sidetheconsole. When lookingatthepanel,theswitch
on the left is for the port battery and engine, the right
switch is for the starboard battery and engine.

The bilge pump will still draw power from the batter-

!
Whena batterydischarges,theactive materialonboth
positive and negative plates converts to lead sulfate,
causing the plates to become more alike in an elec-
trical charge. The electricity conducting battery acid
becomes weaker and the voltage drops. As the bat-
tery remains discharged, the process continues until
recharging the battery becomes impossible.
If the battery does become run down be sure to re-
charge it as soon as possible. Over charging the bat-
tery can be just as detrimental to its life as running it
down too far.
