Caterpillar Marine Unveils Cat® C9.3 ACERT™ Power Solutions for the Commerical Marine Market

November 30th, 2015: Griffin, Georgia – Caterpillar Marine is pleased to announce its release of the Cat® C9.3 ACERT™ Marine platform to the commercial market.

The EPA Tier 3 compliant marine C9.3 ACERT is an excellent addition to the Cat Marine power range.

Raising the Bar

At its core, the C9.3 ACERT is a 6 cylinder, 9.3 liter engine derived from the existing and highly reliable platform within the Cat engine family that produces excellent power density. “Marine customers were looking for a true commercial application with the need for higher load factor capabilities,” Luke Zito, Caterpillar Large Power Systems Division marine value engineer said. “The C9.3 ACERT now strengthens the lower power range of our commercial portfolio, while serving various marine markets.” The engine has been designed with extensive customer input coupled with legendary Caterpillar integration experience. Gathering and understanding customer feedback has also led to a larger variety of vessel specific solutions offered directly from the factory. “An array of optional attachments are now available because of the feedback received from the field,” Zito stated. “An example of this input is the C1 certified variable speed auxiliary rating that will be able to drive items such as deck cranes, winches and pumps.”

Delivering Uptime and Optimizing Customer Value

Sold and serviced by the most extensive dealer network in the world, Cat Marine engines are delivered with comprehensive warranty packages and offered with extended service plans. The C9.3 ACERT continues the legacy of durability, reliability, maximum fuel efficiency, low cost of ownership and world class support provided by the Cat dealer network.

The C9.3 ACERT Radiator generator set package will be on display during the International Workboat Show, December in 1st – 3rd in New Orleans, Louisiana, booth #2802. For more information on Caterpillar Marine, visit
