A small, reliable, smooth running Generator Set for all your
shipboard needs; 120 volt electrical power at the turn of a
switch for: Electric Cooking, Microwave Oven, Refrigeration,
Cabin Appliances, Power Tools, and Navigation/Communication Equipment. Like all Westerbeke Generator Sets, it is fresh
water cooled with an Engine mounted Heat Exchanger. The
Engine and Generator are connected through special "Commonized" Drive Discs, Flywheel, and Flywheel Housing into a
compact, carefully aligned Generator Set. The complete unit is
mounted on lightweight rails through soft flexible Isolator
Mounts that prevent the transfer of vibration. A lightweight
removable Drip Tray is fitted under the unit between the
mounting rails. The Engine is fitted with an Electric Fuel
Pump and Self-Bleeding Fuel System that eliminates hand priming and bleeding. Cast iron cylinder head and block plus swirl
type combustion chamber produce quiet running unmatched
in the industry.

ENGINE SPECIFICATIONS
DESIGN FEATURES
Special attention was paid throughout the design to
noise levels. A Bosch type fuel injection pump is used
which limits fuel quantity in the first part of the injection
stroke. This, together with a throttle-type injection nozzle
and a swirl combustion chamber, prevents an abrupt
rise in cylinder pressure and softens combustion noise.
To avoid resonance of the cylinder block, the crankcase
is carefully ribbed for rigidity.
Despite the engine's small dimensions, there still is a
stroke of 2.68 inches. Three compression rings and one
oil control ring are used for good balance of the moving
piston and further reduction of mechanical noise and
vibration.
The valve cover is cast damping component.

a noise
Both cylinder block and head are cast iron which is more
sound deadening, rigid , and long-lived than aluminum .
The result is sound expressed in DB (a) readings at one
meter with full load, of 86 Decibels at 1800 RPM. Using
optional Sound Guard Decibels reduce to 69 - truly
remarkable performance.
Additionally, less blow-by, better thermal flow, less friction loss , and lower oil consumption , leading to longer
life between overhauls, are the result of these studies .
Engine starting has been given special attention. An
automatic fuel advance system, along with the starting
motor, makes starting easy at 50°F. For lower temperatures, preheating glow plugs are standard equipment.
The engine is designed with easier maintenance in mind .
For example , the camshaft and governor shaft are gear
driven in the normal fashion, but the fuel injection pump
and oil pump are built in and driven by the main camshaft. Simplicity of design has produced a thoroughly
modern engine of less than 350 parts, so arranged that
injection pump, governor, throttle lever, fuel filter, cartridge type oil filter, and oil dipstick are all on the same
side of the engine.
