Uhhhhh, anti fouling paint
Just prep the metal with a metal primer designed for bronze. WM has such a primer but it is expensive. I share mine (you don't need much) with the sail club as the can will probably last me a lifetime.

Diver
I have a diver clean the bottom, prop and shaft every 4 months. This seems to work well and does not cost that much.

While Don Casey....
... does not recommend painting your prop and shaft with bottom paint, I assume he means not painting them without first using an anti-corrosive metal primer. I used Interlux Primocon primer on my bronze shaft and then painted them with modified epoxy bottom paint. In retrospect, I'm not sure if the bottom paint was/is needed. It may be the primer, being zinc based, would do the job all by itself.

anhydrous lanolin
I saw this in a "Things that Work" (or something like that title) sailing book, however, I have not tried it myself--but it sounds intriguing. In order to prevent barnacles and other underwater growth the book suggested spreading anhydrous lanolin (available by special order at most pharmacies) all over the shaft and prop itself. Apparently it is some sort of a natural derivative of wool, and a waterproofing agent. The book also said to use gloves when spreading it because it is very difficult to remove from skin. I'm going to have the yard do this when I have my boat bottom painted again in a week or two, so we'll see. Anybody else heard of this?
