Suitable for pleasure craft, particularly small boats and 25–60-feet motor yachts, the C7.1 marine propulsion engine features a common rail fuel system that allows optimal combustion and reduced emissions.
The silence of the engines and the reduced combustion process noise, thanks to the advanced electronic control, is one of the strong points of the C7.1 marine propulsion engine. Another great advantage is the fact that the C7.1 engines do not emit visible smoke during operation.
Why Choosing It
Reliability and durability
Superior response time and acceleration for improved handling and safety; grid heater to facilitate engine starting at low temperatures; electrical advantages with 12 V or 24 V electrical system; highest paint quality standard.
Easy to use
Compatible with Cat® Displays to monitor all vessel operations; optional engine-mounted display panel with engine start, stop and diagnostics; single point of access to simplify maintenance; wiring with woven cover for a more pleasant appearance of the components subject to maintenance; provision for gplink for remote monitoring.
Respect for the environment
No visible smoke at start-up or during operation; common rail fuel system for optimal combustion and low emission levels; lower combustion noise thanks to advanced electronic control; closed crankcase ventilation system for better engine room cleaning; electronically controlled supercharger for industry-leading torque and throttle response at low speeds, while maintaining fuel efficiency at higher speeds.
