Diesel engine manufacturer Yanmar unveiled two new motors and announced acquisitions and partnerships at the 2018 Progressive Insurance Miami International Boat Show.

“With the focus to produce the best, most innovative marine diesel engines at the heart of our mission, we are combining Yanmar’s own proven expertise with exclusive technology from our new strategic acquisitions and partnerships to offer a unique range of products and complete solutions to a wide variety of marine customers,” said Floris Lettinga, Yanmar Marine International’s senior global sales manager in a statement. “We have incorporated our innovative technology into our latest engines to complete our electronic engine line-up from 40 to 440 hp, all complemented by our universal control system. Plus we are capitalizing on exciting growth and investment opportunities to ensure Yanmar is uniquely positioned as the world’s leading total system supplier.”

First, the company introduced the 3JH40, the latest addition to its lineup of engines with common-rail fuel injection. The 423-pound, three-cylinder engine has a displacement of 1.6 liters and is the marine industry’s smallest common-rail inboard diesel, according to Yanmar. It produces 40 hp and is targeted at small leisure and commercial vessels.

The water-cooled engine could be good for new builds or re-powers, and Yanmar is targeting it at monohull and catamaran sailboats up to 45 feet as well as small motor vessels and light duty commercial craft.

Yanmar added to its 4LV series of CR engines with 230- and 250-hp versions. The new motors have a maximum rpm rating of 3800 and incorporate updated technology, including a counterbalance shaft that minimizes vibration and noise levels.

To control all its common-rail engines, Yanmar introduced its JC20 Joystick maneuvering system. It was first introduced in 2017 and is now available for twin straight inboard installations with a bow thruster.

The new feature lets owners of powerboats and sailing catamarans dock with more control. The system automatically adjusts the speed of the engines and uses the thruster to move the vessel in tight quarters. The JC20 joins the manufacturer's 4JH80 steerable pod joystick for larger sailing yachts and the JC10 Joystick, used for twin stern drives.

Adding to its list of global partners, Yanmar acquired Flexofold, Danish manufacturer of folding propellers for sailboats. Yanmar also announced the launch of the Dtorque 111 twin-cylinder 50-hp diesel outboard engine following an agreement with German manufacturer Neander Shark for global distribution. Yanmar also partners with Vetus for bow thrusters.
