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.
The New C7.1 Engine Offers High Power Density, Fast Acceleration and Quiet Operation
Miami, Florida – Caterpillar Marine is pleased to announce the launch of the Cat® C7.1 high-performance diesel engine for recreational applications. The new propulsion engine is available in three ratings: 507 mhp (373 bkW), 456 mhp (336 bkW) and 406 mhp (298 bkW), all at 2900 rpm. All C7.1 power ratings meet EPA Tier 3, IMO II, EU Recreational Craft Directive and EU Stage IIIA regulations. The new platform will be available to order from the global Cat dealer network in March 2016.
“The new turbocharged C7.1 platform is a powerful, compact addition to our high-performance product portfolio,” Charlson Smith, Caterpillar Marine sales manager noted. “The engine offers a superior power to weight ratio, resulting in a swift response time and speedy acceleration.”
The C7.1 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. “Beyond the quiet, smokeless performance of the 7.1, a key benefit to the customer is the serviceability of the engine due to its small footprint. Maintenance is made easy even in the most compact of engine rooms,” said Smith.
The Cat C7.1 marine propulsion engine will be on display at the Caterpillar booth at the 2016 Yachts Miami Beach show. Visit Caterpillar on Collins Avenue, Ramp 15; Yacht Pavilion 2-5.
