Weird Machinery
In 1920 Henry Ford bought a yacht from the US Navy and named it Yankee Clipper. He had the steam recip machinery removed and replaced it with a Sun-Doxford . It was a 330SB4 engine which consisted of two 330 mm bore engines with aluminium columns and entablature mounted on a cast iron bedplate. It produced 1500 bhp at 200 rpm and each crankshaft appeared to drive a separate propeller although that must have been very difficult hydrodynamically as the props would have been very close together - or even overlapping. Or could it be that that the two shafts were combined in a gearbox near the stern to drive a single prop as the original steam engine probably did? Does anyone know?
