Owners of diesel-powered yachts and power cruisers have another option for onboard power generation from Westerbeke Corp. The Westerbeke 10BTDA, the latest addition to the Avon, Massachusetts, company's line of marine generators, is a three-cylinder, 1.3-liter unit that runs on diesel fuel. According to company literature, the 1,800-rpm generator meets Environmental Protection Agency emissions requirements, as well as the more stringent emissions requirements of the California Air Resources Board.

Standard features of the 10-kW model (which can be converted onboard to a 7.5-kW, 1,500 rpm unit) include full instrumentation and safety shutdowns in the event of high water temperature, low oil temperature and high exhaust temperature. The generator also has a 50-amp battery-charging alternator. For improved service access, the seawater pump is located on the front of the engine.

The generator's design permits installation of an electric clutch and hydraulic pump to the unit's "power takeoff" interface. This enables the 10BTDA to power bow thrusters, compressors, winches and more.

Among the generator's additional highlights are an extra oil-pressure switch for remote control, a tuned air-intake silencer with a filter, an external connector for remote panels and an AC circuit breaker bolted to the unit's frame. Also available for the 10BTDA is a frameless sound guard comprised of removable panels. According to the manufacturer, the frame can be removed without tools, which makes service easier and reduces generator weight.
