SPECS SUMMARY

Minimum Rating404 BHP (301 bkW)
Maximum Rating660 BHP (492 bkW)
AspirationTA, TTA
Rotation from Flywheel EndCounterclockwise
C18 ACERT auxiliary/generator set engines incorporate a separate circuit aftercooling system (SCAC) for all configurations. The primary advantage of the SCAC systsem is reduced aftercooler corrosion since no sea water circulates through the aftercooler. Many other improvements on these engines also contribute to minimizing owning and operating costs. The IMO II compliant ratings are available with heat exchanger or keel cooled options. All major MCS type approvals are available from the factory.
