Marine turbochargers are a type of forced induction system that are used to increase the power output of marine engines. They do this by compressing the air that is drawn into the engine, allowing it to burn more fuel and produce more power. This is especially useful for larger vessels, as it allows them to generate more power without having to significantly increase the size of the engine.

Turbochargers work by using exhaust gases to spin a turbine, which is connected to a compressor via a shaft. As the turbine spins, it drives the compressor, which compresses the air that is drawn into the engine. This compressed air is then mixed with fuel and ignited, resulting in a more powerful combustion process.
