1. Put the boat on high support or a trailer to align the rudders. Pull the rudder
down so they sit tight in the rudderstock;
2. Take the Philips screw out of the tiller-arm;
3. Place the tiller extension in between the arms;
4. Measure the distance between the leading edges of the rudderblade (see A in
the illustration below) and compare this length with the distance between the trail-
ing edges. (see measurement B) For good alignment the distances should be equal
to each other or facing inwards between 0-2mm. Hence, the trailing edge
(measurement B) distance could be 0 to 2mm longer.
Make sure the measurement is done level to the boats beam and perpendicular
(same height) to the blades leading and trailing edge . (E.g. as done by the white
tape in the illustrations)
5. Check if the rubber rod lengths of the tiller-bar are equal to both sides, to allow
proper movement and screw the Philips screw in. Pre-drill the screw hole with a
2.5mm drill bit.
