NEW FOR 1991 - WESTERBEKE'S MODEL 82B FOUR DIESEL ENGINE
Having introduced the first small diesel engine for use in Auxiliary Sailboats in the late Fifties,
Westerbeke's goal has been to design dependable products with the important standard and
optional features needed by the customers. The
new Model 82B Four is representative of that
effort. Here's why: • OVERSIZED COMPONENTS •
The transmission, heat exchanger and engine vibration mounts are all oversized for high
reliability. '
• SUPERIOR ENGINEERING •
The engine mounts are of the fail-safe type with the engine mounting bolt held captive so it
cannot pull apart. Because
of the heavier loads, a two belt system provides the power for the
optional alternators and refrigeration compressor minimizing the chance
of slippage and
premature belt failure.
• OUTSTANDING STANDARD FEATURES •
The 182 cubic inch engine is naturally aspirated which provides extra low end horsepower,
makes it simpler and easier to install and adds to its reliability. The engine
is more tolerant of
exhaust back pressure and a smaller two inch exhaust hose can be used saving cost, space and
the need for a large hole through the hull. Convenient domestic hot water heater connections
are part
of the cooling system and are provided on the engine. Aselfbleeding fuel system
saves the owner the hassle of purging air from the engine fuel system
when changing filters or
when the engine is inadvertently run out of fuel. The engine oil cooler is built into the
engine block for reliability and long life. Other features such as high coolant and low oil
pressure alarms, reliable glow plug starting aide, electric engine shut-off, transmission oil
cooler and much more are
all included as standard. Most important is the "One Side Service"
feature for ease in performing daily service checks and routine maintenance.
• UNIQUE, FACTORY INSTALLED OPTIONS •
Achoice of anyone of four optional high output battery charging alternators are available in
place
of the standard 51 ampere alternator. A90 ampere single output is one choice. The
other three choices are a 135, a 165
or a 190 ampere alternator. These latter three alternators
all feature dual outputs, capable
of charging two banks of batteries without using a battery
splitter. This means fewer connections and more efficient charging. Another important option
is provisions for a rotary refrigeration compressor. Engine mounted, it adds less than three
inches to the installed height. Factory engineered and factory installed, the owner and builder
benefit from a complete and properly designed compressor drive.
• INSTALLER FRIENDLY.
With the builder/installer in mind, Westerbeke has designed the mounting system to provide
common bed widths and heights. The engine beds are in line with the propeller shaft allowing
fore and aft engine positioning while still maintaining shaft alignment. The narrow profile
(only 23.3 inches wide, above the beds) minimizes installation space. Exhaust and water
connections for standard size hose are provided eliminating the need for additional fittings.
Flexible fuel connections ending in standard pipe threads are also supplied. The smaller two
inch exhaust hose permitted by the naturally aspirated engine
is easy to install and saves space
as well as cost. Important options are factory designed and installed and the engine comes as
a complete package, ready to drop on the beds. The self bleeding fuel system saves time
during testing and commissioning.

Four cylinder, four cycle smoothness
in a lightweight, compact engine
Many features are
standard equipment
The new Model82B Four represents the latest
engine design
from Westerbeke. With alow and
narrowprofile it is lightweight and easily installed.
The naturally aspirated design provides extra low-
end power as well as simplicity and reliability. The
standard transmission, fresh water cooling system
and captive fail-safe mounts are all oversized for
added dependability.
Engineered
with aself bleeding fuel system,
front mounted sea water pump, oil drain hose and
one-side servicing, the product is easily maintained.
Acomprehensive listoffactory designed and installed
options allows
you to custom tailor your engine to lit
yourindividual requirements.
Parts and service are available worldwide.
Westerbeke engines
and generators can be serviced
by over 600 authorized dealers strategically located
in major navigable waterways in the United States
and Canada, as well as in 22 countries overseas.
