The MR504LB is a 4-stroke, turbocharged and aftercooled diesel engine with electronically controlled direct injection. It offers excellent performance with low fuel consumption.
Cooling is controlled by separate fresh and salt water circuits, with extractable hoses for easy maintenance.
The oil circuit (which is cooled by means of a fresh water heat exchanger), water and air circuits have been designed to reduce external flexible pipes to minimum to reduce loss of liquids in the bilge.
Auxiliary devices are driven by a Poly-V belt to ensure excellent power transfer and long life compared to traditional solutions.
The dimensions and weight of the engine make the engine easy to install in small spaces.
