The new generation
Yanmar BY series made its UK
debut at the Southampton Boat Show in 2006. Developed in conjunction with
luxury car manufacturer BMW, this new series of engines set new standards for
high performance marine engines and significantly widen the propulsion package
choice for boat builders and their customers.
There are four engines in the series, two four-cylinder diesels at 150MHP
(110kW) and 180MHP (132kW), plus two six-cylinder models at 220MHP (162kW) and
260MHP (191kW), rated speed 4,000 rpm.
The engines will be available for both shaftdrives and sterndrives. At two
litres and three litres, they are lighter, more compact and cleaner than the
models they replace. They are turbocharged and intercooled with the
turbocharger on the inboard four-cylinder and the six-cylinder models are
wastegated. The four engines are available with the latest Kanzaki marine gears
or a choice of Bravo One, Two or Three sterndrives, developed specially for
diesels.
