We answer a similar thread some time ago, i guess you have your prop shaft pointing a bit to port or starboard , is not in the true centerline of the
boat, under
power prop wash the side of the
rudder pushing the
helm in question, live with it because is a normal thing in IP, you can maybe use the
wheel brake to mitigate the helm, or use the
sails and use the
engine only for
docking....
