I splash tomorrow, and the yard painted my bottom late last week. I replaced the shaft zincs myself, however they did not paint the rest of the shaft and none of the prop. I remember last year as the boat was going in they asked me if I wanted the shaft and prop painted and I said sure. Now I am not sure. What is the norm if there is one. I need an answer as I splash tomorrow AM.

Do not..
Do not paint a prop or shaft with a copper based paint! They make special paint for painting underwater metals. It's designed to not increase the galvanic issues that copper paint will. I have never painted my shaft, bronze thru hulls or shaft and never had a problem..

Use Pettit ... "Zinc Coat Barnacle Barrier"
.... on your prop and shaft (not the strut or the zincs). Its a spray-on product - just two thin coats needed. http://www.defender.com/product.jsp?path=-1|10918|296162|11453|311507&id=157662 If you order from Defender, you'll probably have it in 1-2 days to LI from Defender.

I Agree with Landsend
I always paint my shaft and prop and have had NO problems (Micron CSC) in 13 years.

why paint?
I have tried various techniques through the years including using the same bottom paint that I used on the boat as well as Trilux prop and drive paint and also no paint with a coat of teflon grease. What I have concluded is that what works best is using the boat and spinning the prop. The little critters don't adhere to a spinning prop (nor does most paints). Come July, I dive under the boat and clean any growth (minimal) and do the same again in August. Have a good summer and happy sailing!

I have painted my bronze prop
and shaft with copper based bottom paints, but always using something like Interlux Primocon as a primer first. I've never had any galvanic action from doing this, but Maine Sail's warning not to use copper based paints directly on your shaft or prop is well founded. I've also only had limited success in preventing hard growth on my shaft and prop, too. At the end of the season, I usually have about half dozen barnacles here and the on the shaft and prop, and most of the Primocon and bottom paint (hard epoxy) have worn off. This makes prep for next season a bit easier. I think this is about as good as I can get for the brackish, medium growth area of the Chesapeake that my boat sits in when I'm not using it.

USE EPOXY BARRIER FIRST
As long as you use a barrier coat primer first you should be able to paint on bronze. Pettit sells one I've used, then painted Micron over it. I switched to Interlux spray, primer and anti fouling, both will work. The Interlux takes a while to cure. If your going in tomorrow your options are limited. Go to West Marine and get a quick drying epoxy barrier paint, then use what ever you have on the bottom, it should work. I wouldn't go in without anythiny on the prop or shaft. Here on LI, you will get growth and it will effect engine performance.
