Marine Generators Depot supplies Westerbeke Marine Generators for recreational boats, cruising yachts, sportfishing vessels, and commercial marine applications. Westerbeke offers both marine diesel generators and low-CO gasoline marine gensets, giving buyers a broader choice of onboard power systems than many diesel-only brands. Current diesel models are available in both 50Hz and 60Hz configurations for different vessel electrical systems.
The current Westerbeke diesel range covers popular output classes from approximately 5kW to 29kW, including 5kW, 5.5kW, 6kW, 7.5kW, 7.6kW, 8kW, 10kW, 11kW, 12kW, 12.5kW, 15kW, 23kW and 29kW marine generators. This makes the lineup relevant for buyers comparing a compact 5kW boat generator, an 8kW yacht generator, a 10kW–15kW onboard genset or a larger marine power system for greater hotel and auxiliary loads.
Westerbeke diesel generators are built around low-speed operation, with current 50Hz models generally operating at 1500 RPM and 60Hz models at 1800 RPM. These fixed-speed configurations are well suited to vessels requiring stable AC power for marine air conditioning, refrigeration, battery chargers, water heaters, pumps, galley appliances and other onboard electrical consumers. Selecting between a 5kW, 8kW, 10kW or 15kW marine genset should always be based on actual vessel load and motor-starting requirements.
A distinctive part of the Westerbeke portfolio is its low-CO gasoline marine generator range. Current multiport EFI models include approximately 3.5kW, 4.2kW, 5kW, 6.2kW, 7.5kW, 7.6kW, 9.5kW, 12kW, 15kW, 16kW, 18kW, 20kW and 23kW configurations. Westerbeke uses electronic fuel injection and electronic speed control on these models to improve starting, frequency regulation and emissions performance, making them particularly relevant to gasoline-powered boats where matching the vessel’s primary fuel system can simplify onboard fuel arrangements.
For owners searching for a compact or quiet marine generator, Westerbeke offers several low-profile gensets designed around restricted machinery spaces. For example, the 3.5kW low-CO model is one of the smallest units in its gasoline lineup, while the 7.5kW and 9.5kW MCGA generators combine low-speed operation with compact marine packaging. Depending on vessel size and electrical demand, these classes can suit everything from smaller cruising boats to larger yachts requiring air conditioning and multiple hotel loads.
Westerbeke generators are also strong candidates for marine generator replacement projects because the manufacturer maintains extensive documentation for current and older models. When replacing an existing Westerbeke genset, Marine Generators Depot can help compare rated kW, voltage, 50Hz or 60Hz frequency, engine speed, dimensions, cooling connections, exhaust layout, and available installation space. A replacement 8kW or 10kW marine generator should not be selected solely because its output matches the old unit.
Whether your vessel requires a 5kW Westerbeke diesel generator, an 8kW boat genset, a 10kW yacht generator, a 15kW marine diesel generator or one of Westerbeke’s low-CO gasoline generator options, Marine Generators Depot can assist with model comparison, repower applications, technical configuration, service parts and worldwide supply for recreational and professional marine power requirements.
