Our Newest and Smallest Low-CO Generator!
Westerbeke, the first company to bring constant speed EFI generators to the marine market introduces another first: the smallest 3.5 kW low carbon monoxide generator available. The new 3.5 SBCG low-CO gasoline generator joins the already comprehensive line of Westerbeke low-CO gasoline generators that dramatically cut carbon monoxide emissions!

Multiport EFI and Electronic Speed Control
The new 3.5 SBCG low-CO gasoline generator features multiport electronic fuel injection (EFI). Multiport EFI provides optimum fuel efficiency, easy starting and improved reliability. In conjunction with multiport EFI, electronic speed control (via electronic governor) maintains the engine at a constant speed (precise frequency regulation) and eliminates “bogging down” when load is applied.

Smooth, Quiet & Compact
The 3.5 SBCG not only has one of the smallest envelopes available for a 3.5 kW marine gasoline generator, there is not another generator like it. Operating with 2-cylinders, the 3.5 SBCG is an extremely smooth running 3.5 kW.The unit also operates at a quiet, electronically controlled, 2200 RPM. So quiet, it doesn’t require a sound shield. No other generator in its class is quieter!

Lightweight & Powerful
Weighing in at only 188 pounds, the fresh water cooled 3.5 SBCG is powerful enough to run an air conditioner or water heater, etc.

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.
