CHARLESTON, S.C. – Cummins Inc. (NYSE: CMI) is bringing its new QSB6.7 to Miami. Cummins' 550 hp diesel engine now offers the power density needed to reach speeds of more than 80 mph in the performance boat market.


During the Miami New Yacht & Power Boat Show at Sea Isle Marina February 14-18, the KAAMA 48 -- powered by twin QSB6.7 550 hp engines -- is available for a demonstration. To schedule your demonstration, contact Andy Kelly at 850-258-3249.


KAAMA, founded by Betty Cook, is a prominent brand name in the performance boat market with a rich history in the boat racing community dating back to the 1970s.


Diesel engines offer a number of benefits compared to gasoline engines, and this is particularly evident in the performance power boat market. Diesel engines have lower maintenance costs, better overall dependability and longer warranty coverage period.


There are also significant service interval differences between diesel and gasoline engines. The Cummins QSB6.7 requires an oil change every 250 hours while an oil change is required every 25 hours on a comparable performance gasoline engine. The average cost of an oil change for a gasoline engine is $250 per engine every 25 hours, while the average cost of an oil change for the QSB6.7 is $750 per engine every 250 hours. A comparable gasoline engine also requires valve spring replacements between 100-125 hours as well as a major refresh between 200-300 hours, neither of which are required with the Cummins QSB6.7.


Diesel engines provide better overall dependability than gasoline engines, as well. The Cummins QSB6.7 provides 550 hp turning only 3300 RPM while a comparable gas engine provides similar hp between 5000 – 5400 RPM. Higher engine speed causes more stress and wear on the internal components resulting in a shorter life expectancy.


The QSB6.7 is also backed by the standard Cummins 2-year/1000-hour warranty with an additional 4 years/2000 hours of coverage for major components.
