Propeller shaft coupling
*) Female coupling, recessed in flange plane
Flexible propeller shaft
coupling
Together with a flexible mounted engine and a fixed
stuffing box, the propeller shaft must be fitted with a
flexible propeller shaft coupling. See combinations on
pages 34–35.
NOTE! The alignment of the engine is just as impor-
tant with the above propeller equipment as for a rigid
shaft connection. The flexible stuffing box and propel-
ler shaft coupling are not designed to absorb a con-
stant angle deviation.
