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.
