Market Overview

Marine Propulsion Engine Market Overview

Marine propulsion is the system or mechanism used to generate thrust that allows a small boat or even a ship to move across waterways. Modern ships are usually equipped with mechanical systems consisting of an electric motor turning a propeller, or even pump-jets or an impeller.

These ships employ reciprocating engines as their main source of power because of their robustness, operational simplicity and lower emissions. The power required by a ship largely depends on the way it is used during regular operations - for e.g. - A passenger ship requires less power than either a trade or naval ship. The marine propulsion engine market serves offshore support vessels, commercial vessels, inland waterway vessels, submarines and more.
