The Swivel Pin Drive Cantilever Socket Assembly is a bracket designed to attach the hull-side end of a swivel pin drive to a vertical surface, i.e. a wall. The bracket is attached to the hull's vertical surface, and the bracket is 230mm long. During installation, it is not always possible to precisely control where the rear end of the ST1000+, ST2000+, ST4000 swivel pin drive is attached. The most sensible, convenient, and strongest location must be chosen. At the same time, important installation dimensions must be adhered to, which are 460mm from the tiller arm towards the pin handle and as parallel as possible to the boat and tiller. Another important dimension is the so-called “Midstroke”, i.e. the centre position, which is 589mm for the ST1000+ and ST2000+ and 620mm for the ST4000. These are the distances between the centres of the tiller and hull-side attachments. For an ideal result, it may be necessary to use various extension links, fittings for raising or lowering the pin plane, and extension brackets that attach to a horizontal or vertical wall.
