Traditional direct-coupled 1,800 rpm gen-sets are often too large and heavy to fit in many small to medium-sized vessels where space is at a premium. Using a patent-pending design, Next Generation Power Engineering, Inc. offers an ultra-compact, lightweight 3.5KW diesel machine that doesn't resort to the current trend of high speed 3,600 rpm operation.

A rigid engine-to generator attaching plate, combined with a state-of-the-art helical style timing drive system, permits a lower rpm operation. This allows the engine to run at a comfortable and quiet mid-range speed of 2,800 rpm, while still providing an AC output of 60 Hz. The 7 hp Kubota single-cylinder diesel engine uses a horizontal design, making the UCM1-3.5 the lowest profile gen-set built to date.  Dimensions are 28'' long x 15'' wide x 15'' high at a dry weight of only 160 lbs.

Many small gen-sets can't run air conditioners and motors due to their low horsepower and marginally-sized generators. This gen-set uses a heavy duty 5.0KVA generator end, allowing easy starts on up to 16,000 BTU air conditioners or pairs of smaller AC units.

The UCM1-3.5 is available in a standard version or in a modified configuration that is Ignition Protection Certified for use in gasoline powered vessels. Diesel gen-sets in gas boats are becoming more popular as generator manufacturers are dropping their gasoline lines due to safety and liability concerns. With a 5-10 gallon auxiliary tank, owners of gasoline boats can now enjoy the safety, reliability and fuel economy of diesel at about the same price as current gas gen-sets.
