3512C High Displacement Propulsion Engine

3512C High Displacement Propulsion Engine

The Cat 3512C marine propulsion engine makes your investment work harder. Through a wide range of available power ratings, no required aftertreatment technology, and nominal rated BSFC fuel consumption – it will drive down your total cost of ownership. With a redesigned piston bowl shape to improve combustion, and improved fuel delivery, this engine is IMO II emissions compliant and committed to sustainable environmental development. Single-source support, the Caterpillar warranty, and industry-leading one-year warranty on parts make the 3512C a fully integrated marine power solution
