The 3.5 SBCG is the smallest petrol marine generator in the range; its compact size and 3.5kW output at only 2200rpm makes this Westerbeke generator truly remarkable. Fresh-water cooled via dual circuit, this petrol generator is powerful enough to run an air conditioner or water heater and battery charger. The 2 cylinder fuel injected engine is smooth and ultra-quiet, so quiet in fact that Westerbeke do not offer a sound shield.

Safely Leading The Way

The first company to bring constant speed EFI generators to the marine market, Westerbeke manufacture low-CO petrol generators which dramatically reduce carbon monoxide emissions, make boating safer for you and the environment!

Efficient & Reliable

Westerbeke low-CO petrol generators feature multiport electronic fuel injection (EFI). This provides optimum fuel efficiency, easy starting and improved reliability. In conjunction with multiport EFI, electronic speed control via an electronic governor maintains the engine at a constant speed and eliminates ‘bogging down’ when load is applied. 


Smooth & Quiet

These generators run so smoothly and quietly that a sound shield is not even offered as an option by Westerbeke! You can relax and enjoy life on board whilst your generator purrs away doing the hard work.

Simple To Operate

A simple ‘one-touch’ start/stop control panel is mounted on the generator with an hour meter and LED warning lights.  Advance Yacht supply a separate start/stop switch with a harness which can be mounted remotely for ease of starting. The main control panel on the generator provides fault finding codes via the annunciator light strip, so checking out a problem with your generator is very straightforward.
