C18 ACERT Tier 3 Recreational

DESCRIPTION

The C18 marine propulsion engine has ratings for recreational applications that meet U.S. EPA Tier 3, IMO II, and EU Stage IIIA Regulations. This marine engine incorporates the latest core engine system innovations to provide maximum benefits in power density, performance, emissions, and fuel efficiency. Not only is it equipped with engine monitoring and protection features, it is also compatible with Cat display and vessel control systems. With this engine comes the unmatched worldwide marine support network including Cat dealers and hundreds of authorized marine dealers. Their combined experience and expertise, products and services, backup and support allow your recreational pleasure craft to remain precisely that — a pleasure.

Separate circuit aftercooling system

The primary advantage of the separate circuit aftercooling system (SCAC) is that no sea water circulates through the aftercooler
