I have tried painting the prop and shaft with bottom paint, grease, grease/pepper, and just leaving the bronze prop and shaft bare, but by August the barnacles/seaweed start taking over. Is there anything that will last one season in keeping the barnacles off. When I have dived to scrape them off I usually cut my hands on the barnacles. I'm thinking of trying the outdrive spray, but the can states it's for aluminum.

Sure there's a Cure for Barnacles
John Try the link to the C34 website message board. Prop and shaft antifouling. Good luck. Better days are ahead for you and your hands. Stu

The outdrive spray didn't work for me
On the recommendation of a powerboat friend, I tried it. At the end of one season, my prop was completely fouled and the 1.25" shaft was 3" in diameter from growth!! I am with you.... I've tried all the same things you have with very limited success. I thought I had it knocked with Desitin & cayanne pepper. Worked great the year I used the boat a lot and and motored heavily. Last year when the boat sat unused due to weeks of rain, the grow the took over. Let's hope someone has an answer that will last the whole season. Rich

I have had...
..relatively good luck with bottom paint. I use Micron CSC (ablative) and my prop and shaft remain virtually free of growth. I end up with more under the keel than on the shaft/prop.

Stopping Barnacle Growth
There is a book titled "I wish I'd thought of that", sort of like a "Hints from Heloise" for sailors. In it, its mentioned that applying Anhydrous Lanolin to your running gear will keep barnacles from growing. You have to order the stuff from your local pharmacist, and the cost is about $15-$20 or so. I haven't tried it (yet), just telling you what the book said.

Allen, it is temporary.
Allen: Most anything that you put on a prop or shaft is only temporary. Once the water and the small pieces of matter that are floating around in the water along with the rotation and motion of the boat moving get going your protection is going away very quickly. This stuff is fine if you have a boat that is going to sit for several months, then the products become more efficent. Some of the products for diaper rash can do the same thing too. I have also heard that STP Oil treatment works.

Interlux has worked at our dock...
Now granted, I have not looked at my prop yet, as it does not get pulled until spring, but a boat 3 slips down had nary a barnicle and bright blue paint remaining after an entire season. Check the link...

Two methods
I have found two different methods that seem to work for me in the moslty salt water of Barnegat Bay NJ. Clean the prop and shaft and apply at least two coats of one of the Interlux Barrier coat products follwed by a coat or two of your favorire copper bottom paint. The copper paint works only when "electrically" separated from the metal of the prop and shaft. Lately, I have been using one of the clear, two part outdrive/outboard spray paint products. It is easier to use and works just as well as the barrier coat method.
