I have 2001 Bav 40. It has a rubber boot on the rudder post - just above the lower bearing and below the quadrant. It acts as a seal over the lower bearing and the post and is held in place by three circular clips. I noticed that the metal flange set into the top of the boot has completely rusted away and as a result the top of the boot does not seal.Has anyone else had this problem? Anyone know where I can get a replacement boot. Does the rudder need to be dropped to fit the boot or can it be pushed down from the top if the top bearing is removed? Thanks.
