SigmaDrive shaft couplings are relatively simple to install and will give years of trouble free maintenance.

 

SigmaDrive units are simple to fit, often with the vessel alongside.  The taper lock collar also means that the shaft does not need to be modified or machined to accept the unit.  The Jet drive (left), standard (center) and STS drive (right) shown below highlight how little space is required to install a SigmaDrive.
