What is the main advantage of using superchargers in marine engines?
Increases thermal efficiency
A supercharger forces a greater mass of air into the cylinder than the engine could draw in by natural aspiration, raising the density of the intake charge.
With more air (and therefore more oxygen) packed into the same cylinder volume, more fuel can be burned completely, producing more power and more effective work from each combustion cycle.
Because more of the fuel's heat energy is converted into useful work, the engine's thermal efficiency and power-to-size ratio improve, which is valuable in space-constrained marine installations.
A supercharger increases, not reduces, air compression/charge density, and it improves rather than decreases efficiency, so the other options are incorrect.
Hence, the answer is Increases thermal efficiency.
