Nicolas,

The lip seal and “donuts” are the seals that keep the ocean from coming in where the thruster shaft goes down through the hull.  They are critical maintenance items and should be changed every year—two at the most—to avoid unexpected leaks.  These times are not governed by sailing hours since the failure mode is when the foam rubber in the donut seals compresses and hardens.  This reduces its ability to properly maintain a seal.
