INBOARD ENGINES

Selecting the best marine diesel engine is not simply a matter of choosing the engine with the highest horsepower. A suitable propulsion engine must match the vessel’s displacement, hull design,…

Buying a marine diesel engine is a technical investment that deserves considerably more attention than simply comparing horsepower and asking for the lowest price. Whether the engine is new, used,…

Marine diesel engines are not interchangeable simply because they produce similar horsepower. The right engine depends on the vessel’s displacement, propulsion arrangement, operating profile, required speed, available engine-room space, duty…

Marine diesel engine repowering is the process of replacing an existing inboard propulsion engine with a new engine while adapting the vessel’s propulsion system to the replacement power unit. It…

Choosing between a new and used marine diesel engine is ultimately a question of lifecycle value, not simply purchase price. A used engine can substantially reduce the initial capital requirement…

Marine diesel engines are engineered for demanding propulsion, but reliability depends heavily on maintaining the systems that support combustion, lubrication, cooling and fuel delivery. Preventive maintenance is not simply about…

Marine diesel reliability is not determined by a single specification, horsepower figure or manufacturer name. Engine life is the result of how the engine is designed, installed, loaded, maintained and…

Installing a marine inboard diesel engine is considerably more than lowering the engine into the engine room and connecting the controls. The engine, marine gearbox, mounts, propeller shaft, coupling, propeller,…

A marine diesel exhaust system performs two essential functions: safely removing combustion gases from the engine and managing the heat, noise and emissions produced during operation. Unlike a road vehicle,…

The lubrication system is fundamental to marine diesel reliability because it creates a controlled film of oil between moving components that would otherwise experience direct metal-to-metal contact. Engine oil lubricates…
