Cat releases C9.3 ACERT platform to commercial market

NOVEMBER 30, 2015 — Caterpillar Marine has released the EPA Tier 3 compliant Cat C9.3 ACERT marine platform to the commercial market.


The engines and generators are MCS approved commercial solutions available with optional alarm and protection systems supporting all global marine markets. Ratings are available meeting EPA Tier 3, EU/CCNR Stage II and IMOII regulations.

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 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," Mr. 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."

The following is the full range of ratings associated with propulsion, auxiliary, and generator sets:


375 bhp at 1800 rpm (280 bkW)  416 bhp at 2100 rpm (310  bkW)  476 bhp at 2300 rpm (355 bkW)


369 bhp & 436 bhp at 1800 rpm (275 bkW - 325 bkW)     292 bhp & 362 bhp at 1500 rpm (218 bkW - 270 bkW)

Generator Set:      

224 ekW - 300 ekW at 60Hz      185 ekW - 250e kW at 50Hz

Sold and serviced by an extensive dealer network, 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 1 – 3
