Yanmar Marine International said it will introduce 6LF and 6LT series diesels to the U.S. market at the Progressive Miami International Boat Show in February. The engines debuted at the Düsseldorf show last week.

The company said in a statement that the 6LF and 6LT models range from 485 mhp (478 hp) to 640 mhp (631 hp) and are designed for recreational and commercial use.

The 6LF engines have a top rpm of 3,000 and are available in 485-, 530- and 550-mph ratings. The 6LT engines have a maximum 2,350 rpm rating and offered in 500-, 580- and 640-mph models. The engines feature Yanmar’s VC20 control system and are global emissions-certified. They are also available with a ZF transmission.

“With the launch of our new engines, Yanmar’s renowned common-rail range now reaches 640 mhp, representing a significant expansion of our lineup from the previous limit of 440 mhp,” global sales manager Martijn Oggel said in the statement. “We are excited to bring the efficiency, performance and low-emission benefits of the higher power 6LF and 6LT models, alongside the reassurance of Yanmar’s reputation for high quality, reliability and technological advancements, to more boat owners and commercial operators.”

The engines will be available in the third quarter of 2020.
