propeller paint

Prepped the prop with a Dremel tool and soft wire brush attachment to polish then painted. The paint was still 90% there when boat was pulled in the fall. Make sure the anodes don't get the paint on them and no paint on shaft where they are mounted. Basically clean prop and shaft, attach anode/anodes, tape anodes with painter tape and spray. Remove tape and launch when ready.
I would not recommend using any antifouling bottom paint on prop, but have used Pettit Prop Coat Barnacle Barrier (formerly called Pettit Zinc Coat Barnacle Barrier) with decent result. Defender Marine sells product priced at $24.99 for 16 oz. aerosol can. This is not inexpensive, but you get several seasons out of single can. Someone also recommend use of zinc metal primer paint available at hardware store; certainly less expensive.
Third on the Rust-Oleum Cold Galvanizing Spray Paint. $6 for the large spray can. I started using it when I ran out of the Pettit. Prep, then three coats. We're close enough to NJ to I think your results will be similar. Zero growth. Prep as above by Caspurr.

Former Hunter dealer but retired some time but did sell the Hunter 33 and even took the boat to Annapolis Sailboat shows. Good investment to put a three blade prop on for better propulsion and control. You still have prop walk in reverse.
There has been much on what to do to paint a prop and strut. First there is a new spray can paint with zinc by Petit and generally takes one can to do a prop but the jury is still out on that. This is what a good friend of mine taught me as he owned a major sailboat yard working on all types of power and sailboat hulls. This has worked for years and is tried and true but there are some costs.
1. Prep the surface and even sand. Clean or wipe down with acetone.
2. Apply Petit primer # 6455 and let dry for two hours.
3. Apply Petit tie coat # 6627 and let dry for two hours.
4. In North Carolina, I then applied Petit Trinidad SR
I tried so many other ways when selling sailboats and this is what worked the best for me. Yes you have some investment but it worked.

I have a similar fixed 3 bladed prop on my Westerly Oceanlord. I use primocon spray on prop/strut/shaft. Then two coats of Trilux II ( outdrive paint). I still get barnacles, but they spin off leaving a notable circle. Nothing I have ever use has kept barnacles away unless the boat is in constant motion.
FYI, I use white trilux so the
prop /shaft are more visible when I dive to check it out in late july/early august.
Everyone has their favorite plan to keep those critters at bay.
There are so many factors that go into what make barnacles like or dislike a particular prop/shaft:
mooring or slip
stray currents ( electrical)
zinc placement
grounded or ungrounded boat
water temperature and movement
on and on...........

The jury is hardy "still out" on zinc-based cold-galavanizing coatings for use on running gear. They have many years of real-world use, are popular and relatively effective. I would recommend them as a cheap alternative to Prop Speed, which is hands-down the best anti fouling for metals available. What I would not recommend is traditional anti fouling paint, which tends to last a very short time and requires extensive preparation for use on metal.
Just put a new Campbell Sailer on our First 38. Made a world of difference. If you order one they take all the specs for your boat, engine and trans and custom make it. About $850 Cdn.
An added benefit: if your zinc "anode" falls off, the paint with become sacrificial.
...and since you are spraying on a zinc coating, you don't need to tape off the zinc anode. Just put the anode on first on the cleaned shaft.
The zinc paint is something like 96% pure zinc. I may be off a percent or two but it is close. I have been spraying my shaft zinc for at least 4-5 years with no detrimental effect.
