product-C176-16 Marine Propulsion Engine
The C175-16 is the first Cat marine engine with core ACERTTM Technology, designed and built from the ground up. This offers maximum performance along with EPA Marine Tier 3 and IMO Tier II emissions compliance with no aftertreatment. With unrestricted continuous and heavy-duty ratings, you get morepower with plenty of room for growth, so you maximize productivity while minimizing cost of ownership. With a bore of 175 mm (6.9 in) and a stroke of 220 mm (8.66 in), the C175-16 is highly efficient while providing increased propulsion output in a high speed engine platform. Additional features include: Turbocharged and aftercooled aspiration, MCS approved monitoring, alarm, and protection system. Cross-flow head design, simplified electrical system. The C175-16 is backed by a Caterpillar warranty and the best service network in the industry. The global Cat dealer network means customers can count on the service and support they need for their marine engines no matter where their vessel is located.
