| Developed under a close working relationship with car manufacturer BMW, Yanmar claims the new engines should significantly widen the propulsion package choice for boatbuilders and their customers.
The models are four-cylinder diesels at 150MHP (110kW) and 180MHP (132kW), plus six-cylinder models at 220MHP (162kW) and 260MHP (191kW), at a rated speed of 4,000 rpm. They will be available for shaftdrives and sterndrives.
At two litres and three litres, they are lighter, more compact and cleaner than the models they replace. All of the engines in the range meet the new EPA Tier 2 and European RCD emissions regulations.
The diesels are similar in weight to petrol engines of equivalent capacity, and produce a similar rate of acceleration.
Electronic control is by second-generation common rail with magnetic injectors and the engines include a CAN bus system using NMEA 2000 protocol. They are turbocharged and intercooled, and the turbocharger on the inboard four-cylinder and all the six-cylinder models is wastegated.
The four engines are available with the latest Kanzaki marine gears or a choice of Bravo One, Bravo Two or Bravo Three sterndrives, developed specially for diesels.
The BY series is due to go into full production in early summer 2006. |
