IMPORTANT
PRODUCT SOFTWARE NOTICE
Product software of all kinds, such as
brochures, drawings, technical data,
operator's and workshop manuals, parts
lists and parts price lists, and other
information,
instructions and specifi-
cations provided from sources other
than Westerbeke,
is not within Wester-
beke's control and, accordingly,
is
provided to Westerbeke customers only
as a courtesy and service. WESTERBEKE
CANNOT BE RESPONSIBLE FOR THE CONTENT
OF SUCH SOFTHARE, MAKES NO WARRANTIES
OR REPRESENTATIONS WITH RESPECT THERETO,
INCLUDING THE ACCURACY, TIMELINESS OR
COMPLETENESS THEREOF, AND WILL IN NO
EVENT BE LIABLE FOR ANY TYPE OF DAMAGES
OR INJURY INCURRED IN CONNECTION WITH,
OR ARISING OUT OF, THE FURNISHING OR
USE OF SUCH SOFTWARE.
For example, components and sub-assemb-
lies incorporated in Westerbeke's
products and supplied by others (such
as engine blocks, fuel systems and com-
ponents, transmissions, electrical com-
ponents, pumps, and other products)
are generally supported
by their manu-
facturers with their own software, and
Westerbeke must depend on such software
for the design of Westerbeke's
own
product software. Such software may be
outdated and no longer accurate. Routine
changes
made by Westerbeke's suppliers,
of which Westerbeke rarely has notice
in advance, are frequently not
reflected
in the supplier's software until after
such changes take place.
Westerbeke customers should also keep in
mind the time span between printings of
Westerbeke product software, and the
unavoidable existence
of earlier, non-
current Westerbeke software editions in
the
field. Additionally, most Wester-
beke products include customer-requested
special features
that frequently do not
include complete documentation.
In sum, product software provided with
Westerbeke products, whether from Wester-
beke or other suppliers, must not and
cannot be relied upon exclusively as the
definitive authority on the respective
product.
It not only makes good sense,
but
is imperative that appropriate
representatives of Westerbeke or the
supplier in question
be consulted to
determine the accuracy
and currency of
the product software being consulted
by the customer.

INTRODUCTION
This manual describes the operation, adjustment and maintenance of the
Westerbeke
Whaleboat Marine Diesel Engine and is designed to be a guide for
those concerned with the operation
and maintenance of these diesels. This
engine incorporates a basic engine
model known variously as 4-99, 4-107 and
4-108. You will notice continual references to these three model numbers
throughout the workshop portion of this manual. They are used to distinguish
among the three major engineering changes already made to the engine.
The diesel engine closely resembles the gasoline engine inasmuch as the mech-
anism is essentially the same. Its cylinders are arranged above its closed
crankcase,
its crankshaft is one of the same general type as that of a gasoline
engine;
it has the same sort of valves, camshaft, pistons, connecting rods and
lubricating system and reverse and reduction gear.
There it follows to a great extent, that it requires the same treatment as that
which any intelligent and careful operator would give to a gasoline engine and
that gross negligence such as running the engine short of oil, with sludged oil,
dirty filters, or with water boiling will have the same expensive consequences.
The diesel engine does differ from the gasoline engine however, in the method
of handling and firing its fuel. Carburetor and ignition system are done away
with and in its place is a single component -the Fuel Injection Pump - which
performs the functions of both.
Unremitting care
and attention at the factory have resulted in an engine cap-
able of
many hundreds of hours of service. What the manufacturer cannot
control
however, is the treatment the product will receive in service. This
part rests with you.
Whenever service parts are ordered, always give complete description and part
numbers with engine model and serial number; as an example:
'Please supply:
For Whaleboat Marine Engine No. ED7153480
10 of 15559 Oil Filter Cartridge'
The engine number is stamped on the starboard side of the engine on the forward
end of the Camshaft Chamber and on the port side of the engine near the fuel
pump.
