In this paper, the problems of diagnostics of main propulsion marine engines are presented. Marine engine is a complex technical object. For the purpose of diagnostics is convenient to divide the engine into several units – subsystems such as: piston –crank assembly; working medium exchange system, fuel supply system, lubricating system, cooling system, starting up – reversing system; combustion chamber. The organization of the marine engine diagnostic process can usually come down to two stages, general diagnostics and damage location. The diagnostic system of marine engine is able to assess the current engine condition and give forecast concerning its future operation in a complex way with the use of computer technology. Working out operating decision was based on proper preparation of operational parameters which were processed in a computer according to defined algorithms. Diesel engine diagnostic systems of merchant vessel engines are discussed. Marine engines operate under specific conditions which have a considerable influence on their characteristics change and can cause their increased wear and even failure. Marine engines run in constant rolling conditions. Although rolling does not directly affect the characteristic change, it can cause systematic wear of engine components i.e. bearings.
