I’ve had a quotation of 950 euro, plus lift étais it worth it, how long does it last ?

1-2 years on average, depends heavily on your usage.

Using Trilux , quoted €200 +tax apply .
worked last year on the stern gear .
You are Arnesons so I would imagine more energy , read predisposition for localised cavitation and surface stripping of what ever is applied .
Trilux needs a suitable primer as well .
Last season I never bothered with prop scrubbing.
Labour rate at Amico Loano is €51 / hr + tax btw .

Total cost to lift, acid clean and apply propspeed, 2,300 euro

At that price, personally, I wouldn't bother...I self applied ours but it's a lot of meticulous work...not least sanding the props to 80 grit texture before the primer goes on.

Seems pricey .
Its just the props that need to stay clean , the rotating bits .The rest is not so important.
I have never seen anything used on surface drive props in the yard(s) and simply dock , or is it dog walking ?
As I said the energy transfer will just wipe anything useful off .
Perhaps have it done , try it scratch the itch next time it’s lifted for its annual , as opposed to another lift on top of the one .

I tried it a few years ago and wasn't impressed. It does work as long as you use the boat regularly. If the crusties a grip - and they will, you can't jet wash propspeed as it comes off! So I use velox, that mostly works and mostly stays on.

To be fair the propspeed bumf on line does say over and over regular usage .Something like 8 hrs every 3 weeks min .
Wether that pattern will fit in with Chris‘s usage remains to be seen .
My doubt ( despite PS blurb ) is with Arnesons the cavitation / energy concentration of 800 Hp on areas the size of your hand , namely the hub of a Arnie prop pushing 36 T , or sharing it with the other side so 18 T .I think nothing will stick it will get blown off in the trim transition when accelerating.
It might hold once up and running and optimal trimmed but getting to that point it will be removed by the shear energy and side effect off cavitation nibbling away at the surface coating .

Velox works and is much cheaper.
Trilux I find useless.

Chum tried DIY version of one of these snake oils, around 3 months after application, boat was lifted again fot a jetwash......................not a trace of the goo remained anywhere, merely some well attached barnycules.

Takes me absolutely no longer than 25 minutes to clean a 2 bladed 16 inch feathering prop, with brick cleaner; which is a strong Hydrochloric acid one. With more blades it would not take much longer. The time is spent getting the brushes & acid ready, gloves & goggles on & water hose to wash off after & clearing up. So an extra couple of blades would not be double the time

Use Trilux on outdrive props in UK, applied once per year - no growth

The problem is in the Med. fouling grows very fast and a lift out for a jet wash is needed if you want to go boating beyond September. In the uk I never had any prop fouling issues, Edit - to illustrate I took a UK boat out to the med @ 12 years ago now. The props were untreated but nice and shiny. Naively I wasnt aware of the growth rate in the med. They lasted 6 weeks. Had to have the boat lifted and they were like a privet hedge, absolutey bristling. So bad the boat would struggle to move. Now I use Velox and I get about 4 months then it needs a lift and clean or a diver. in the Uk the slimy fouling you get tends to come off with a few long trips. In the med it doesn't come off with use.

I tried Velox with recommended undercoat many years ago, it was relatively new then, it was free issued to me to try it out on a Targa 34 (I think Hurric. also had some gratis too). It did not seem to work any better than Trilux (not much does out here) so I continued to use the latter.
However, I was speaking to Tomasz our former boatyard manager here last week, when I had a cutlass bearing renewed, he said that if very carefully prepared and applied, it is definitely achieving good results - so next year, I may give it another go!

There in lies the issue .
Its all in the prep and adherence to said instructions. Esp the primer stage .
I personally ( with mates ) tried everything and nothing worked on both out drives and shafts .So just gave up ( been boating in the Med since 2005 ) and acid cleaned the props then dived in and scraped as the season progressed.
For the sake of €200 done by professionals in the marina yard last year I thought try it .Why not ?
In the naive thought some one some where in the Med with all the boats must know what they are doing .
It worked .
I asked this time what is was and the guys said Trilux .Comes in black and pale cream .The primer is a yellow / gold colour .
No idea how they apply it .They normally lift 3 boats under 25 T each week and do them.
As said last time I used it ( 3 pairs of eyes graduate level at the instructions ) it failed .

The slime on the hull isn’t too bad, I can scrape the barnacles off the hull, they only seem to attach where there is sun light, it’s the arneson that are a bugger to keep clean, I have to dive down and clean the props every two weeks in the summer, was ok to begin with but I’d rather spend my time relaxing these days.

I must say having used most solutions on metalwork in the past, nothing seems to work that well in the warm Med. waters on a MY where we are.
I will definitely try Velox again next year, applied by a local business that many of us use and trust in La Rapita, it was great when I had the Targa though - just beach the SS Duo-props and you could scrape them all from the BP - but as said above, it was needed about every 2 weeks in summer

IMO none of the coatings stick to the props.
Great if you don't use the boat but there is just too much energy being dissipated down there.
My solution is spend your time polishing the props etc.
Then lift the boat and do a quick acid wash.
I can get ours acid washed in the time that the rest of the boat gets pressure washed.
Before
And about 45 minutes later after a pressure wash and acid wash.
In Spain, we buy the acid from the local supermarkets
