Every houseboater knows the importance of having a reliable
power source onboard at all times. Without power, there's no hot water for
showers, no way to watch movies or enjoy late-night card games with the family.
These days, generators are more than electricity-generating, noisy machines on
the stern of your boat; they are smaller, quieter and more environmentally-friendly.
Take a look at these models from some of the big players in the marine
generator market and find one to suit you and your entertainment provider this
Cummins Onan's Marine QD 7.5
Rugged dependability, high quality and innovation make
Cummins Onan Marine Generators a leader in marine generator design and
development, providing performance you rely on, whether out on the water or at
The digital QD (Quiet Diesel) Series models are the first
marine generator sets with self-monitoring capability and network communication.
The optional Cummins Onan Digital Display provides
user-friendly diagnostics, including extensive engine and alternator
information, self-diagnostic features and text display.
The Cummins Onan Marine Generators with advanced design and
development processes use technology to lower sound and vibration. The sound
shields minimize noise and deliver better sound quality and the optimized
mounting system greatly reduces vibration.
Certified to U.S. Environmental Protection Agency (EPA)
Onan branded products are used in recreational vehicle,
marine, commercial mobile, residential standby and portable applications.
Cummins Power Generation branded products include temporary or permanent
pre-integrated Power Command power systems and related accessories. Power
system products include diesel and gas generator sets, automatic transfer
switches and paralleling switchgear used in commercial and industrial
applications for emergency backup or as the primary power source. Cummins Power
Generation also provides services ranging from system design, project
management, financing, and operation and maintenance contracts to development
of turnkey power plants.
Kohler's 7.5EKD (distributed by Nixon Power Services)
The 7.5EKD from Kohler features an integral heat exchanger,
CARB/EPA emission-compliant design for low CO emissions and one-side
serviceability of the fuel filter, cooling systems and lubrication system. It's
clear that if you're looking for a generator that is easy to service as well as
environmentally-friendly, the 7.5EKD is one to consider.
In addition to the previous features, this model is
sequential-port throttle-body fuel-injected and comes with an attached overflow
The generator itself comes with a remote start 12-pin
connector, and a voltage regulation of plus or minus 1.5 percent. Both the
rotor and stator are vacuum impregnated and coated with high-bond epoxy
varnish, which helps prevent corrosion in high-humidity areas.
Copper windings ensure minimal heat buildup, while the
insulation meets NEMA standards for class H insulation.
Directly connected to the engine, the generator has sealed
precision ball bearings with a precision-machined steel sleeve in the end
bracket (or end bearing tolerance ring) to prevent shaft misalignment and
extend bearing life.
Today, Kohler has taken its place on the leading edge of
total solutions for residential, commercial and industrial standby/emergency
power, distributed power, recreational power, rental, power for special events
and more. And as the company sees demand for new and different kinds of power
expanding to levels previously unseen, the commitment to innovative products,
world-class engineering, responsive after-sale support and unmatched value is
stronger than ever.

Northern Lights M673L3
The ideal 6kW generator set is small and lightweight. The
M673L3 certainly qualifies. But it stands apart through its remarkable
long-life reliability. The reason? The M673L3 runs at 1800 rpm (1500 rpm for 50
Hz) instead of 3600 rpm. Consider that during only 2000 hours of operation the
1800 rpm M673L3 will turn 216 million fewer revolutions than a 3600 rpm set.
Its pistons will travel 38,522 fewer miles. Its cylinders will withstand 108
million fewer detonations. Which engine do you think will give more years of
The M673L3 has a balanced Lugger three-cylinder diesel
instead of a rough two banger. Four platform isolation mounts reduce vibration
transmission even more.
For maximum comfort afloat, the new M673L3 has a Sound Maze
air intake system. Air enters through a molded rubber hose and an acoustic
dampening chamber. Air goes in but much less noise gets out. For maximum sound
attenuation, specify a sound enclosure. It is constructed of electrogalvanized
steel panels with a powder-coated aluminum extruded framework, and creates a 23
percent smaller overall package than previous versions.
The generator's automatic voltage regulator is powered by an
auxiliary AC stator winding that isolates it from the main windings. The AVR
always has clean power to provide excitation for faster load response and
better motor starting.
Your air conditioner and other motor-driven equipment will
love being matched with the 673.
A 30 amp AC circuit breaker in the junction box protects
your wiring. Safety shutdowns for low oil pressure, high coolant temperature
and high exhaust temperature protect your engine.
The M673L3 meets US EPA Tier III emission standards. You,
your moorage neighbors and the environment will all benefit.
With 1800 rpm reliability, low emissions, quiet operation
and strong motor starting, good things do come in small packages.
Volpi's Pagura 5000
Volpi's most unique product is its Pagura 5000, which produces 4kW of continuous
power, plus a 300 percent short-term overload capability for air conditioner
start up. It has a remarket weight of only 183 pounds. With its small size and
very low noise rating of 52 DBA, the Pagura 5000 is a clear choice for the
consumer wanting a high-quality marine generator for his houseboat.
Established in 1933, Volpi is currently specializing in
producing diesel marine soundproof generating sets, totally water-cooled,
manufactured for the marine leisure market with a low noise level and with the
lowest weight and size in this market.
To achieve the above target not only the engine is water-cooled but a stainless
steel jacket around the windings with the main benefit to have no need of
ventilation openings into the sound shield, and consequently no noise can
A water-cooled AC generator has a higher efficiency in a more compact shape,
and as fringe benefit does not release heat into the engine compartment where
the temperature in summer can already be high due to the main engine's
Volpi was initially known for assembling petrol and diesel
engines with generators, pumps, compressors and similar devices for naval
shipyard purposes. In the 1980's, Volpi Tecno Energia, following the demands of
the nautical leisure market, oriented itself toward this sector, obtaining a
success higher than expected, enabling the company to develop increasingly more
sophisticated and finalized units for leisure boats.
