Smooth, Quiet and Compact
Designed by Westerbeke, the Company that
pioneered the truly “quiet breed” of generators, the 3-
cylinder, 4.5BCGB is flawlessly smooth, quiet and
compact. The engine incorporates a tuned air intake
silencer and a balance shaft to diminish noise and
vibration. Quieter than 3600-rpm generators, there is
no other 1800-rpm gasoline generator in its size and
power rating! This state-of-the-art generator will
provide all your shipboard power requirements with
the “quiet” that only an 1800-rpm gasoline generator
can provide.
Easy Operation and Maintenance
To minimize engine maintenance, the 4.5BCGB is
fresh water cooled and equipped with a simple
control system without complex, troublesome,
electronic components. Easy access to all servicing
points (single-side servicing) allows easy installation
and routine maintenance.
Powerful and Reliable
The 4.5BCGB is powered by and industrial .66 liter
engine that provides a full 4.5 kilowatts at 60 Hertz or
3.8 kilowatts at 50 Hertz. The 4.5BCGB belongs to a
long line of Westerbeke generators that have been
the pride of many powerboat owners for their
reliability.
Five Year Limited Warranty
The 4.5BCGB is backed by Westerbeke’s 5-year
limited warranty. The presence of Westerbeke in
over 65 countries around the world provides
customers with easy access to parts, service and
technical support worldwide. Established in 1937,
