The line-up of the redesigned M-line marine diesel engines is impressive. With new features, modern appearance and added benefits, the new M-line range is designed to meet future market demand.
One of the most notable changes is the cast aluminium top cover. This cover incorporates various new and innovative features. It includes a water cooled element and absorbs radiant heat from the engine. This innovative concepts results in a significant temperature reduction of up to 15°C – a reduction of 20%! Moreover, the sturdy aluminium top cover significantly reduces the noise level of the engine. In combination with the new air filter, tests show a sound reduction of about 5 dB(A) and “near silent” operation at a cruising speed of around 2200 rpm. Finally the water cooled top cover is designed to be used as a step, making it easier to move around the engine.
Furthermore, the redesigned M-line incorporates many other new features to make life easier for both the boat builder and the end user:
Service parts such as fuses and relays (A), fuel filter and fuel connections (B), impeller (C), oil dipstick (D) and the oil filter (E) are all easily accessible. On all M4 engines the impeller is located at the front, for even easier access.
