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

Less friction. I want all the energy of the 12hp diesel engine to go to the prop.

Hmmm...if it's really, really sticky, it might be using 0.5 even 1 HP

If it did though, it would wear out in about 20 - 50 hours.
But it hasn't. And if it was that sticky, you STILL couldn't tell
the difference if it was replaced with a fabulous Zero-Friction
bearing made of Unobtainium (in my humble view).
So the best advice I could offer (which because it is free, I don't
suppose you will take up) is...leave it alone until it is a REAL
problem.

Good luck
