I know this gets kicked around pretty regular but I thought I would ask the gurus on the forum. I have a 2011 Sabre with single axle vault bearings. The boat only has 60 hours on it so it doesnt get used as much as most or pulled long distances. My question is, being as I dont see any sign of leakage do I do nothing, just keep an eye on them, change the oil in the bath, or change bearings and all? I know it is a crap shoot but I thought I would see what some you you thought. Also, this is the first summer I have owned the boat but i am confident nothing has been done to them previous to me purchasing it. Thanks in advance.
