Diesel engine manufacturer Yanmar has announced that its fourth generation engine 6LY will make its European debut at the upcoming Boot Düsseldorf 2016. The show runs from 23 – 31 January.
The new in-line six-cylinder engine is the fourth generation of a classic model that goes back to 1989, developed specifically for marine applications.
In the new line-up, the 5.8-litre unit develops 440 mhp at 3,300 rpm with added boost from a water-cooled turbocharger. The manufacturer says versions with 400 and 370 mhp ratings are also offered.
The engine uses the same slim-line block as the first-generation units and occupies the same engine unit. Only now, the engine is no longer mechanically managed.
Like all new-generation Yanmar diesel engines, it is now precisely controlled by the latest digital electronics. Yanmar’s VCS (Vessel Control System) to ensure optimum performance and fuel efficiency throughout its operating range. It also interconnects perfectly with other electronic vessel systems as well as giving the option of joystick control the manufacturer’s own wireless lever system.
“The new engine takes what was a very accomplished and highly popular power unit to a higher level,” says Floris Lettinga, Yanmar Marine’s global sales manager. “In its transfigured form we expect to see strong sales for installation in new craft as well as in the refit sector, where its high power density and compactness will make it an engine of choice for replacement not only of earlier Yanmar units, but also larger, heavier units of similar output.”
Now in full production, the new 6YL440/400 will shortly be available worldwide through Yanmar Marine International (YMI) service dealers.
The company will also be exhibiting five more engines from the Yanmar range, all but one of them with common-rail fuel injection.
