B10b Calibration and Installation
The calibration routine should be performed after the drive unit has been fitted to the
vessel and wired up to the autopilot. The RFB should also be electrically connected
to the autopilot prior to calibration (refer to sections C1 and C2).
i) Remove the RFB module from the drive
housing (if already fitted) by removing
the two fixing screws.
ii) Center the rudder of the boat using the
manual helm (you may need to run the
engine to do this).
iii) Calibrate the RFB by aligning the two
red paint marks on the underside of the
unit (Fig B49).
iv) Remove the RFB blanking cap from the
drive unit housing (Fig B50a).
v) Fit the RFB to the drive housing and fix using the two screws provided (Fig B50b).
Ensure that the RFB driven gear is correctly engaged with the drive gear before
tightening the 2 screws.
vi) Refer to the autopilot manufacturer’s installation guide for instructions on any
additional software controlled RFB fine calibration and hardover limitation.
