Having used most products over the years, I have just a few days ago had Propspeed applied, not expecting it to last, we shall see!

We get heavy fouling in Sant Carles, 6m since last lift and pressure wash! before and after:

It certainly will be interesting to see John if Propspeed keeps the growth manageable, watching with interest.

£200 for a 250ml kit for 2 x 2ft props. But more than that, as they are trying to force a pro to use it - they will only sell it to professionals due to EU Reach rules (Force4.co.uk), which we continue to apply post Brexit.

I tried it in the med, yes it mostly works but if you leave the boat for saying 6 months there will be a bit of growth. No problem lift and jet wash it.
Problem, you can't jet wash it, the propspeed comes off. After a year I went back to Velox, not as good overall but more user friendly

The yard offers Velox.....but I didn’t find it effective at all. The problem is exactly as you say the boat can sit for months at a time...we only lift her once a year.

Can’t you dive n scrub as and when ?
It’s only got one wheel .

I used to snorkel two in the SoF in 30 mins .Or mini dive bottle in 20 mins .
Used ( yard did ) it Velox a couple of seasons here in IT and it did work to end of Sept …Although boat was regularly used .

Propspeed as others have said is Uber technique sensitive and for what it costs and typical French yard “ shrug of shoulders “ I want to go home at 5 and have a 2 hr lunch mentality……..the likely hood of your application guys falling short of the meticulous instructions is odds on .Armchair tinternet version and French reality are vastly different.

We are on a two yr lift protocol , had a diver went out yesterday and my numbers are spot on .

Won’t bore 😀you all with EGT s they were lower than normal @ 535 * C .

So the motors are pretty unstressed for 28 knots my eco cruise .

I ll scrub the props up when needed myself .

Exactly, either buy cheap stuff that doesn't work or £200 for stuff that works.

Well it’s on the shelf…at eye watering prices…whether they would refuse to sell it to me is another question

No guarantees but I found the kit went further than advertised. I had a large kit for two 4 blade 25” props and there was a little spare. I had bought two large!

FWIW …

My boat was lifted today. Here is a photo of the port side prop and rudder before pressure washing and acid cleaning. Both were treated with Propspeed when the boat was last lifted a little under two years ago. You can compare with the modest growth on the shaft which was not treated.

After much deliberation I decided that this year the prop will go naked....and I’ll have a year to think about it...in reality, the performance of the boat isn’t that affected by growth on the prop....where I really suffer is growth on the stern and bow thruster...they get weaker and weaker as the season goes by....I can’t get them into any kind of perfect condition that a coating like Propspeed requires....the only way is Porto’s idea of diving underwater with a scraper....the problem is I don’t scuba and I boat year round so the water is too cold

I think it’s a good product and works well if it’s applied properly.

Also, I don’t think it’s as difficult to apply as everyone says. I watched them apply it the last time and while you have to follow the instructions, it’s not a “black art” that requires specialist knowledge. I did get the impression that surface preparation was key … they spent a lot of time sanding and polishing before they started to paint.
