Westerbeke marine diesel generators are high-quality power systems engineered specifically for marine environments, providing uninterrupted electricity for onboard comfort, cooking appliances, and navigation equipment. Operating at low speeds—typically 1800 RPM—these quiet, smooth-running systems minimize hull vibration while maximizing engine longevity. They feature a freshwater cooling circuit that protects internal components from saltwater corrosion and a self-bleeding fuel system that automatically purges air from the fuel line. Offering a wide product range—from the compact BC series to the digital D-NET™ series capable of integrating with smart yacht management platforms—the brand also maximizes onboard comfort through accessories such as sound-insulating enclosures and specialized mufflers.

Westerbeke Multiport Electronic Fuel Injection (EFI) marine gasoline generators set the standard for quiet, reliable, and fuel-efficient power solutions in the marine industry, offering a wide power range from 3.5 kW to 22.5 kW. Specifically engineered for demanding marine environments, these next-generation "Low-CO" models have completely replaced older carbureted units, drastically reducing emissions and eliminating chronic issues—such as vapor lock—often associated with fuel delivery systems. The system utilizes multiport EFI technology to inject fuel directly and sequentially into each cylinder, while also featuring a water-cooled, returnless design that eliminates the fuel tank return line and ensures superior cooling of the fuel system. Furthermore, the generators are expertly engineered to operate at low speeds—1500 RPM (50Hz) or 1800 RPM (60Hz)—reducing the need for complex, heavy sound enclosures while delivering a quiet cruising experience and extending engine life.
