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 BostonWhaler® 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.
Thisis themostimportant identifyingfactor andmust
beincludedin allcorrespondencerelated to yourves-
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
thefinishedproduct is pulled fromthe mold, the deck
and the hull are chemically bonded to form a solid,
inseparable unit.

Thedeckdrainprovidesself-bailingcapabilitieswhilethe
boat is static in the water and no passengers on board.
This feature prevents the accumulation of water in the
cockpit. the drain must be in place when underway.
NOTICE
!
Depending on the type of boat you have, you may
have underwater fittings that need drain plugs.
Garboard drain plugs and fishbox drain plugs need
to be in place before the boat goes into the water.
Any fitting that will be underwater needs to be
plugged or the seacock needs to be closed
NOTICE
!
Through hull fittings should be checked for proper
seal annually. When the boat is in the water the un-
derwater fittings can be checked for dripping. It is
recommended that the underwater fittings be re-
moved, cleaned and resealed every other year.
NOTICE
!
If the through hull fittings need to be replaced, it is
recommended that an authorized Boston Whaler ®
dealer perform this type of repair. Through hull fit-
tings that are improperly installed can cause pre-
mature hull failure and may void the Boston
