Specifications

OVERVIEW

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.

Driving Down Total Cost of Ownership

Wide range of available power ratings, Compliant with no aftertreatment required, Cat® durability

Committed to Sustainable Development

EPA Marine Tier 3/IMO Tier II Emissions Compliant, Common rail fuel system enables low emissions at all levels

Improving Workforce Efficiency

Marine Classification Society approved monitoring, alarm, and protection system, Cross-flow head design optimizes fuel consumption

Fully Integrated Marine Power Solution

13% more power for increased productivity, Standard warranty on all factory-packaged components

Caterpillar Common Rail System

This system features electronically controlled, fully flexible injectors, enabling optimal combustion and low emissions at all levels, along with better transient response.

Cross-flow head design

Improved airflow helps the air/exhaust flow meet emissions and optimize fuel consumption

Simplified electrical system

Allows for easy installation and maintenance, reducing up front and service costs.

New generation of turbochargers designed specifically for the C175

Cast titanium impeller offers five times longer low-cycle fatigue life, and compressor blades are twice as resistant to high-cycle fatigue. Turbochargers are mounted on cast pedestals and center-positioned to eliminate external oil drain lines, reduce the chance of oil leaks, and improve turbo efficiency. The flexible bellows connections used on inlets/outlets of the turbine and compressor housings minimize leakage and provide isolation from external vibrations, motions, and thermal expansion.

Marine Classification Society approved monitoring, alarm, and protection system

Now offered as a factory-installed and warranted option, saving you money and providing a single source for the whole package.

Thermo-laminated heat shields for exhaust components

Easier to install and remove than the traditional soft shields, they save time and money during service. The no-gap fitting enhances safety with better hot spot coverage.
