Tiller bracket s
Where the height of the tiller above or below the cockpit seat or
mounting plane is such that standard mounting is not practical, a range
of tiller brackets allow the tiller pin offset to be varied.
1. Position the tiller bracket on the centre line (upper/lower) of the
tiller and establish control dimensions A and B.
2. Mark the position of the centres of the two fixing bolt holes.
3. Drill two 6†mm (0.25†in) diameter clearance holes through the
centre line of the tiller.
4. Install the tiller bracket using two 6†mm (1/4†in) diameter bolts,
nuts and washers.
5. Bond the fixing bolts in place with epoxy adhesive and fully
tighten the nuts.
