6.6 Tiller actuator installation
The drive unit is mounted between the tiller and a single attachment
point on the yacht structure. For correct installation two basic
dimensions are critical.
ï Dimension A = 620†mm (24.5†in) ñ mounting socket to tiller pin.
Pull out the actuator pushrod to this dimension. If a pushrod
extension or a cantilever mount are required, tables later in this
chapter define the amount by which measurement A is increased.
ï Dimension B = 460†mm (18†in) ñ rudder stock centre line to
tiller pin.
1. Clamp the tiller on the yacht centre line and mark off dimensions A
and B . ( A is measured on port or starboard side of the cockpit
depending on which side the actuator is to be mounted. If a port
mounting is chosen, the autopilot operating sense must be
corrected as detailed in
Chapter 7 . It is not a long job.) Use
masking tape to locate the fixing points.
2. Make sure the measurements are at right angles as shown.
3. Make sure that the drive unit is mounted horizontally.
