Acceleration power is the main feature of the MAN V12-1800 engine. The 12 cylinders that compose it allow the yachts on which it is installed to be brought quickly into the planning phase, reaching high speeds in record times.

Common Rail direct injection allows fuel to be injected at very high pressure. This represents an incredible advantage as it guarantees optimal and comfortable operation of the boat on which the engine is installed.

Its lightweight yet compact dimensions guarantee simple installation. The use of highly resistant materials, however, makes maintenance minimal.

In terms of respect for the environment, the V12-1800 engine complies with current international exhaust gas directives.
