Extension link for stern thruster 76 mm (ST1000+, ST2000+, ST4000 tiller)

The surface pilot extension link is required to extend the surface pilot actuator when it does not extend to the desired position. Extension links are available in increments of 25mm from a 25mm link to a 153mm link. During installation, it is not always possible to check exactly where the rear end of the ST1000+, ST2000+, ST4000 surface pilot actuator should be fixed. Always choose the most reasonable, convenient and strongest place. At the same time, the essential installation dimensions of 460mm from the rudder to the tiller handle and as parallel as possible to the boat and rudder surface must be respected. Another important dimension is the so-called. “For the ST1000+ and ST2000+ it is 589mm and for the ST4000 it is 620mm. These are the distances between the centres of the rudder surface and the hull mounting. The answer to the question, ”but I need a 300mm link and you don't have one“ is to screw the two 153mm links together. However, it is not worth making the extended part unreasonably long, this should only be done if there is really no other way.
