3512C PROPULSION ENGINE (IMO II)
The Cat 3512C marine propulsion engine makes your investment work harder. Through a wide range of available power ratings (including High Displacement 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.
