When hauled out last month had this stuff painted on the prop & shaft for $80nz.
Wasn't planning on this but the launch beside Minaret had it done 2 years previously, it still looked good, just a bit faded.

I was quoted about $120 here for my 3 blade prop. Have to take the prop off and drive it to Seaview (30km away) to get done overnight. Would be a lot less hassle to do it myself.

We had PropSpeed applied when the boat was out of the water in the boatyard a few months back - shows on the bill amongst everything else as NZD160. That for an 18" 3 blade prop (but skinny blades as is a high aspect ratio one).

The yard reckoned it was gaining a widely held good reputation as working well and recommended doing it as we normally only get the boat out of the water every second year. They also suggested it when we were lifted 2 years before but this time I agreed for two reasons - first as a test just out of interest and second when I walked around the lifted boats (that not in Wellington) ALL the better kept ones were using PropSpeed.

So, we will see what it looks like in 2010 .

No, big barnacles after 18 months.
Maybe the bloke who applied it messed up.

I did wonder when I read this thread. Thanks for coming back and answering this, paint it is for me again this year. A nice drop of Micron Extra over a thin coat of Primocon lasted suprisingly well last year.

where to buy 200ml size??

FWIW, I'm currently trying to find another of the trial size (plenty for 2 applications on my 19" max prop, which I know because I had to have my prop reconditioned right after the first installation, due to a tiny pic which got the prop but nothing else underwater).

It did marvelously for us for a couple of years. I'm very interested in where to buy the 200ml size again - Alan, can you help?

So, here's a real-world experience, primarily in relatively warm waters: I'd immediately buy it again if I didn't have to buy liter quantities of it, enough to last me more than 20 years...

Remember last year when someone suggested using a Sharpie pen to antifoul a prop?
I tried it.
Seriously, after a winter of not using the boat until the other day, it was the worst amount of fouling I've seen on my prop, ever, but the Dungies were having fun.

Re: PropSpeed Coating on Gori Props

I had heard reports of success using plain Lanocote (marine grade for rust and corrosion) as an antifouling for props.
A friend with a 4 blade fixed prop agreed to apply a thick layer to 2 blades. The blades were very clean.
It was of no help. After 3 months, in the tropics, he couldn't tell which blades he had put it on.

Re: PropSpeed Coating on Gori Props

Lanocote is 95% lanolin, which is water-soluble sheep grease. It has uses, but since it is water soluble I can't see it being any kind of long-term protection in a wet place. Like, on a boat or under the boat on the prop.

Great way to keep leather sailing gloves soft though.<G>

Lanolin can be modified to be truly water soluable. ,it can readily emulsify with water. It has been used on props for a long time now.

Re: PropSpeed Coating on Gori Props

The trick is that you should not use the prop. So moor or anchor, then dive down to the prop and coat it with lanolin.

Polishing the prop until it shines like gold also helps a lot. We take it to a higher level every haul-out and it becomes easier to keep clean.

We also tried out the spray cans with Barnacle-barrier or something which is a zinc spray. Works better than anything we tried before but still so-so.

West Marine is where I got it, and apparently, that's about the only place one can buy other than commercial quantities of it...

Re: PropSpeed Coating on Gori Props

I use petit zinc coat barnacle barrier on all of our underwater metal. It works great for us,but we pull the boat every winter and it is a fairly low fouling area. It's about 40 bucks a can. I think we use 2 cans to do all underwater metal. I think it would be great for folding-feathering props as it is a very thin coating.

Re: PropSpeed Coating on Gori Props

In the photos at the top, there is no propspeed on the saildrive. The yard in NZ where I am now also treats the saildrive. If my Gori props ever get back from Denmark, I will try it.
I would like to try the zinc barnacle barrier on the metal through hulls, but can't find it in NZ. It seems to have 90+% zinc as THE active ingredient. Oh well, will be back in the warm water of the tropics soon, so it will be easy to scrape them.
