Yanmar 8LV Series Range

Weighing in at a surprisingly lightweight 435kg (dry weight, no gear), Yanmar’s 4.6-litre V8 series offers a viable alternative to a V8 petrol engine.

Most suitable for ski boats, fast planing sportsboats and luxury sportscruisers, the range comprises three models from 320hp to 370hp with a notably wide power band, idling at 550rpm and achieving 3,800rpm at full chat.

These are twin-turbo engines with high-pressure common-rail fuel injection systems, available with shaft or stern drive transmissions and fitted as standard with a 12V/180A alternator. Noise and vibration are notably low; fuel economy is decent; acceleration and torque are excellent.
