Combining innovative technology and simplicity
of design, Westerbeke has managed, once again, to
set the standard in power generation with its new line
of gasoline powered generators, the BCGTC Series.
This new line of gasoline generators is powered
by an industrial three-cylinder gas engine. Like most
Westerbeke gensets, this series incorporates true
one-side servicing for complete access to all
serviceable components.
Like all Westerbeke gensets, these gasoline
generators feature fresh-water cooling and are fitted
with flexible mounts to prevent the transfer of
vibration. Fuel is supplied via a down draft style
carburetor for a smooth and precise fuel flow which
results in an extremely economical and durable
engine.
Perfect for smaller boats with limited space and
heavy electrical loads, the BCGTC Series, along with
its sister product, the EFI Series, are the smallest
gasoline generators Westerbeke has produced. They
have been designed with the boater in mind. All
Westerbeke generators are backed by a five year
limited warranty and by a worldwide network of
master distributors and dealers.
