C7.1

Meet the new C7.1 Commercial Propulsion Engine

C7.1 Marine Propulsion Engine Walkaround

SPECS SUMMARY

Power Range	400 bhp - 500 bhp (298 bkW - 373 bkW)
Speed Range	2900 rpm
Emissions	IMO II, U.S. EPA Tier 3, RCD II, China II
Rotation from Flywheel End	Counterclockwise

The C7.1 marine propulsion engineis ideal for recreational boating applications, specifically smaller vessels and motoryachts ranging from 25 -60 feet in size. The engine features a common rail fuel system enabling optimum combustion and low emissions. The engines provide noticeably quiet operation due to reduced combustion noise through advanced electronic control. Additionally, no visible smoke is emitted from the C7.1 engines during operation.
