Quiet and Compact

Running at 1800 RPM with tuned air intake silencer and 3-cylinder smoothness, the 11.0 BTDB is powerfully quiet.  The generator also features one of the smallest envelopes of any generator in its class.

Precise Frequency Regulation
Electronic governing provides instantaneous response as load is applied or removed from the generator.  No dimming lights associated with mechanical governing speed fluctuation.

Powerful, Lightweight and Reliable
The 11.0 BTDB is powered by a naturally aspirated, industrial, 1.3 liter, engine specially engineered to operate in a hostile marine environment.  Powerful but lightweight, it is economical to operate and designed to run at a slow 1800 RPM for longer life.

Easy Operation and Maintenance
To minimize engine maintenance, the 11.0 BTDB is fresh water cooled and designed with easy access to servicing points.  Individually removable top and side panel of the optional sound enclosure aid installation and routine maintenance.  

Full Torque, Power Take-Off Interface
A customer sourced, electric clutch and hydraulic pump can be mounted to the full torque, power take-off interface for use with such items as bow thrusters, compressors, winches and "take-home" systems.

Five Year Limited Warranty
The 11.0 BTDB 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, Westerbeke is committed to providing its customers with quality products and unequaled after sales support.
