High Performance Propulsion Engines

Industry-leading technology allows Caterpillar to create the most reliable commercial engines for a variety of applications. From tugs and container vessels to yachts and sport fishers, Cat and MaK engines have demonstrated their efficiency countless times. With remarkable reliability and durability, these engines will exceed your expectations for decades.

C8.7 High Performance Propulsion Engine

The C8.7’s sophisticated fuel delivery system allows the use of a radial, belt-driven supercharger in addition to the conventional turbocharger; this feature eliminates smoke and reduces lugging, while delivering phenomenal low-end torque and impressive fuel economy. . FPT (Fiat Powertrain Technologies) Industrial’s advancements in second-generation common rail fuel injection systems paired with an innovative air management system allows the compact C8.7 to develop an impressive 650 mhp @ 2300 rpm while meeting EPA Tier 3 Commercial, EPA Tier 3 Recreational, IMO II, and EU Stage IIIA (EU IW) emissions standards.
