Steam powers two types of engine, reciprocating (with steam driving pistons connected to a crankshaft) and turbine (with steam driving blades attached radially to a spinning shaft). The shaft power from each can either go directly to the propeller, pump jet or other mechanism, or it goes through some form of transmission; mechanical, electrical or hydraulic. In the 1800s, steam was one of the main power sources for marine propulsion. In 1869 there was a large influx of ste…
