Barrus will be unveiling a number of new inboard engines at this year’s Southampton Boat Show.

The new Yanmar BY series, developed in conjunction with car manufacturer BMW, set new standards for high performance marine engines and significantly widen the propulsion package choice for boat builders and their customers. These four-cylinder diesels at 150MHP (110kW) and 180MHP (132kW), plus six-cylinder models at 220 MHP (162kW) and 260 MHP (191kW) are rated at 4,000 rpm and will be available for both shaftdrives and sterndrives. At two and three litres, they are lighter, more compact and cleaner than the models they replace.

The new Yanmar diesel engine, the 4JH4-HTE provides 10% more power than the model it replaces; yet it is 10kg lighter. There is no increase in fuel consumption, in spite of the extra output.

Rated 110MHP (80.9kW) at 3,200 rpm, it is a mechanically controlled, turbocharged four-cylinder diesel with 16 valves, available with a choice of mechanical or hydraulic gears. Higher power-to-weight ratio, compact dimensions, increased torque and low noise and vibration are among the key benefits, while standard features include a four-valve cylinder head, improved fuel injection system, newly designed pistons and heat exchanger, new intake manifold, maintenance-free oil cooler, V-belt safety cover, plus an 80amp alternator.

The new 4JH4-HTE meets the 2007 emissions regulations, compliant with EPA Tier 2, BSO Tier 2 and EU RCD requirements.
