ABSTRACT:
Torque-transmitting accommodation of substantial non-alignment of rotational shaft mechanism, particularly for interconnecting a boat motor's output means (generally vertical) and the boat's submerged propeller shaft (generally horizontal). The accommodation of non-aligned portions of the transmission is provided a flexible drive shaft member, particularly here a tightly-coiled multi-layered cable, insheathed in curved tubing and the cable's flexibility provides capability of rotation in spite of a substantial bend in the transmission of the rotational power.
