Paul,
I must admit that I am confused. Stern tube? Cutless bearing? They do not go
together. The cutless bearing goes into a P bracket which supports the
propeller end of the shaft. I have assumed that this is center fin design
and if it is, the propeller is positioned between the fin and the rudder. In
that design, the stern tube supports a packing gland only, not a cutless
bearing. Please keep in mind that water flow lubricates a cutless bearing,
which dictates that the forward end of the bearing is exposed to the sea. If
your hull design dictates a propeller at the rear of the fin, then you must
use a grease lubed conventional bearing on the sea end of the stern tube.

Hello all.
I have a 34' aluminum sailboat hull that was built some time in the
late 1970's but never finished until now. The stern tube is sch.80
aluminum pipe and was welded by the builder, my question is two fold,
first does any one know of a cutlass bearing to fit pipe approx 1.9".
And second the stern tube seems too be a bit oval, maybe (3/64"-1/32")
probably from welding. Any suggestions?
Thanks Paul
