Cox boasts the aluminium alloy block and head-equipped CXO300 will save 25 per cent in fuel compared to a petrol-fuelled equivalent, via its high-pressure common rail fuel injection system. Fuel burn is officially rated at around 18 litres an hour at 2500rpm.
It also comes with a joystick system that will support up to six of these bad boys strung across the transom. At 375kg each, that’s the equivalent of more than 2.2 tonnes, 1500kW and 3900Nm hanging off the back of the boat.

The engines are also compatible with EPA3, IMO 2 and RCD 2 emissions standards.
