While changing my sailboat shaft seal
, I had to pull the 25mm shaft back a few inches through the cutless bearing. A small 1/8" bit of rubber seemed to come back with it from one of the internal ribs. Otherwise the bearing has no loosness, the rubber firm, the shaft in good shape, no vibration, and all looks okay. I really don't want the work
of dropping the rudder
to get the shaft out and a new bearing in. Is a small piece of absent rubber going to have much effect or is this a sign of significant deterioration?
