Adjusting the chain tension
Adjust the chain tension until it is just tight, so there is minimal lost motion between the drive
sprocket and the rudder stock.
Note:
If the chain tension is not set correctly, the resulting lost motion will impair steering performance.
To adjust chain tension:
• Drives mounted horizontally: place as many of the supplied shims as necessary under the
mounting foot (see
Figure 6
).
• Drives mounted vertically: use the slots in the mounting foot to move the drive up or down
(see
Figure 6
).
