C7.1
C7.1 High Performance Propulsion Engine
DESCRIPTION
The C7.1 marine propulsion engine is 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.The C7.1 marine propulsion engineis ideal for recreational boating applications, specifically smaller vessels and motoryachts ranging from 25 -60 feet in size.
