Do you paint the prop and shaft or not. I once spent $30 for a can of spray that was to work wonders and it did nothing.It seemed to attract barnecles. Thanks, Richard
Painted Prop ???

There's them that do and there's them that don't
The problem is that the metals in the antifouling paint can set up very expenxive galvanic acion with the prop and shaft. I can't comment on the "miracle sprays" as I've ever used them. I don't put bottom paint on props andshafts.

paint the prop
paint it and it just comes off, appears theres no good solution to this one yet.. I leave the shaft and prop unpainted and clean it every 6 months.

Petit Zinc Rich Barnacle Barrier .....
works for me. Otherwise I get a huge barnacle ball. It seems to last ... I get upwards of a thousand miles before it 'goes' - mostly the trailing edges of the prop blades. It needs to be sanded down and reapplied yearly as it does become 'rough' over time. I keep my boat in brackish water that sometimes goes salty, sometimes fresh.

Hi Richard, I've had good results with...
Desitin (baby bottom stuff). I rub in two thick layers of the stuff on the prop and shaft. The last time I did this was 2004. Each year I have a diver check the hull, clean the bright work then apply this stuff. This year he scraped three small barnacles from the prop. The shaft was clean. Zinc oxide is the active ingredient. Terry

Duke,
Everyone seems to have their own take on what to put on the prop and shaft; from (expensive) "Propshield" (which one friend, who uses it, say works very well) to (very inexpensive) diaper rash ointment. Some people DO paint their prop/shaft. Unfortunately with the prop spinning at 1000rpm (at typical sailboat cruising speed after ~2.5 trans. reduction), typical antifouling paint doesn't stay on very long. Personally, like RichH, for the past few years, I have been using "Pettit Zinc Coat Barnacle Barrier" aerosol spray paint. Seems to work pretty well for up to a year and isn't too expensive. Just put my boat back in the water (after painting, etc). I used the Petit aerosol and like Terry, then, after it dried, smeared a tube of (generic) diaper rash ointment over it to see what happens. I have tried the diaper rash ointment in the past and, for me, it has just seemed to disappear quickly. ... Had a tube left from past years, so, I just slopped it on again... why not?

Hummm, Terry,
I wonder if the colder water of the PNW helps the "Desitin" stay on better than the warmer water over here (that gets up to 80 during the Summer)... Interesting

Here is my experience..... FWIW........
I wish I could recommend a silver bullet for the prop/shaft barnacle problem. I can't. However here is what I have coated the prop & shaft with and the results: Ablative paint: Sort of works until it wears off, unfortunately the wear-off time is much less than my normal season. Maybe if I didn't find the need to motor so much it would last longer.... Hard anti-fouling paint: Again, works a little but still wears off, or maybe the biocide just can't leach to the surface fast enough to be effective. Desitin & cayenne pepper mix: Wow, I thought I had a winner the first year. After using it a second year with poor performance, I realized that the reason it worked so well the first year was that I had gone to Maine for a month and also to the Chesapeake for a month with lots of motoring all the time. The old tin-based spray paint: For whatever reason it didn't work for me. It seemed like the barnacles really loved it. Interlux Trilux spray, $30: One can, six coats. Apparently more barnacle food, it didn't work for me at all. Pettit 1792 Zinc Coat Barnacle spray, $15: Applied 2 coats per instructions. Worked better than anything else. Not perfect, had some barnacles on the hub and shaft, but not a heavy coating. I did cruise to Maine for a month, so had a fair amount of motoring. I have just cleaned the prop and applied 2 new coats, same spray can. Ask me in the fall how well it worked this season. In my boatyard, some owners have had a product called Prop Speed applied. It is a two-part process and the material cost is very pricey- about $200+ for the material plus labor to have it applied. I think you can apply it yourself. The results were varied- some boats it seemed to work pretty well, and others were much worse than my $7.50 worth of Pettit Zinc Coat. I understand that it is supposed to last more than one year, but I don't know the details. It really doesn't matter, there is no way I'm going to spend that much money on the prop. It would be cheaper to hire a diver twice a month.....

Painting the prop
I have used both the sprays and regular hard epoxy bottom paint with great success. You can use either but the secret is that the prop and shaft have to be properly primed before applying the paint. The Trilux is expensive but you can get several years out of one can. Of course, you have to use their primer for best results. For the past few years, I can been cleaning the prop and shaft to bright metal and then applying two coats of Interprotect 2000 followed by two coats of my hard epoxy copper paint. I have perhaps one or two barnacles at the end of the season. I use my boat almost every weekend and motor about one hour over the two or three days. Some but not all of the paint is lost from the prop by the end of the season. Don't paint under or over the zincs!
