5.4 Tiller drive (tiller pilots only)

Critical dimensions

Installing the tiller drive involves mounting it between the tiller and a
fixed point on the boat's structure. Two dimensions are critical for
correct installation:
• Dimension A = 620 mm (24.5 in): the distance from the
mounting socket to the tiller pin. Pull out the drive pushrod to this
dimension.
Note: If your installation requires a pushrod extension (see page 51)
or cantilever mount (see page 55),this dimension will increase.
• Dimension B = 460 mm (18 in): the distance from the rudder
stock's center line to the tiller pin.
