The C12.9 marine propulsion engine is ideal for high performance marine applications including yachts, fishing vessels, military vessels, governmental vessels and various other commercial high performance marine applications. The C12.9 is designed to be integrated with both the Cat Three60 Precision Control shaft line maneuvering and engine control solution as well as other marine industry throttle controls. The electronically-controlled C12.9 is offered in two power ratings: 850 mhp at 2300 rpm and 1000 mhp at 2300 rpm. Both ratings meet EPA Tier 3, IMO II, EU Recreational Craft Directive and EU Stage IIIA regulations. In addition to high power density, the C12.9 offers high torque at low engine speeds and fast acceleration throughout the entire engine speed range due to its air system design of integrated series turbochargers and a supercharger.
