I have a Scampi 30 sailboat. The shaft has a thrust bearing behing the
propeller that is made out of some kinda oil impregnated plastic. This
is wide open to the outside. I want to replace this friction bearing
with a thrust roller bearing. I am thinking that I should get an
encapsulated stainless bearing but I cant find such an animal. Can
somebody point me in the right direction, or tell me if this is a good
idea.. Thank You
