I am using Trilux on my propeller but it does not work very well. Loads of barnacles. Would adding grease on top of Trilux work better.

I used to use Lanolin. It smelt like a revolting roast of mutton but my hands were really soft after I'd applied it.
I had to have the boat lifted within about 6 weeks or less of her being relaunched and there wasn't a trace of it left.
I should think grease is much the same.
About 2 seasons ago I bit the bullet and tried Velox. It's a) not cheap and b) a PITA to put on but it seems to stay on and works as an antifoul. One small can of primer and same of velox itself was around £45 but has now done 3 seasons and should do a fourth. And I have zip connection with the firm that makes it.

+1 for Velox.

Just veloxed mine a few days ago, launch on Sun.
Have previously tried polished prop, lanolin, trilux, and silic one. All a waste of time- it'll be interesting to see if this works.

I found Seajet 034 much better than trilux.

Based upon recommendations from the forum I now first paint my prop with Hammerite Special Metals Primer, then Primocon and finally Trilux 33.
The antifoul lasts better than without using Hammerite but still washes off.
An additional benefit is that the Hammerite really sticks so anode wear is less due to it reducing those pesky electrons running amok

Just watching sailing uma on utube and he said the yellow stuff he was painting on lasted about9 months don’t know if his yellow paint will work but might be worth a look.

I also use Hammerite Special Metals Primer, sticks really well to a well keyed prop. I use hard antifoul on top of the primer. I found that a very gentle sand of the primer, once it has had a couple of days to go really hard, makes the antifoul bond much better. By the end of the season most of the antifoul is gone but he primer is still there and is clean, I don’t think nasty marine stuff likeS the primer.

Ditto for trying Hammerite Special Metals Primer and 3 coats of Velox this season ( boat moored on a swinging mooring in Holyhead harbour ) boat going in this coming weekend so fingers crossed as nothing else has worked !

The answer to a clean prop is so very simple - use it.

When I approached a prop repair specialist with this question I was firmly advised to forget the expensive chemicals, rather to my surprise. They recommended an enamel finish (on Alu props) I have followed this advice and find the beasties do not adhere to the main part of my 3 blader so I retain most of the thrust, but congregate happily on the boss - the downside. I slap the A/F recommended on my S leg and they make merry there too. Some years more and others less - as we all experience.
Is there any other conclusion than moving a boat discourages growth, but leaving it on a pontoon or mooring for any length of time is (at least in east coast waters) to be disappointed. The paint seems a long winded, expensive and noxious distraction. Hulls the same.
I hope fellow matelots are facing up to the realisation that all A/F with active ingredients is bound to be banned soonish, and shall we weep I wonder? ife on the hard will certainly be happier and less trying.

You are correct about the longevity of Hammerite Special Metals primer. I first used it in 2012, two coats followed by four coats of Velox (the advice at the time). At the end of that season the fouling was controlled but the Velox had chipped quite badly.
Subsequently I abraded the Hammerite lightly and only applied two coats of Velox, which reduced the amount of chipping. I have used this approach on every season since but amazingly, the same original application of primer is the only one there, I simply rub down and add Velox at the beginning of each season. Here it is again at the end of 2018. By this stage I had also given the P-bracket the same treatment. Both photos before pressure washing

The answer seems to depend on area and usage. When we cruised the Baltic regularly, with some time spent in Dutch fresh water, my prop gave good service with just a coat of lanolin. With less use in home waters this hasn't been enough. Last year I tried SilicOne since it seemed promising. Despite the care I took preparing the prop, keying it and degreasing, there was none left at lift-out, but at least it saved me the trouble of removing it. This year, with such a short season as we haven't launched yet, I will just use lanolin and try a magic potion next year.

I tried lanolin, stove blacking, super polished prop and whatever was in fashion at the time with little success. Hammerite special metals primer and hard antifouling was quite good.
Velox sounds good but I now have an outboard in a well that can be cleaned at leisure.
As an aside, I have noticed that outboard legs are made of fairly thin metal. I expect that they are designed not to be in the water all the time. It's essential to keep the anodes up to scratch.

Hi Daedelus I had never heard of Velox + so thanks for the advice. I have put 6 coats on. I know what you mean about how difficult it is to paint on. Like painting with milk. It says to put on light coats This is impossible. I put 6 thick coats on. I will let everyone know next year how good or bad ll it worked

The yellow paint was probably Propspeed, developed a fair while ago by a bunch of Kiwi's. Here's Hinewai's prop last year just before relaunch.
I've been using it for many years and it works great, has kept my stainless steel prop clean from Melbourne to Dover, and for more than 9 months a time.
A bit fiddly to apply being two coats that need to be applied pretty nippily, the yellow being the base etch primer overcoated with some clear stuff.
They say it should only be applied by specially trained professionals but follow the instructions and it's not hard to get a good job.
OK, it's not cheap but you'll get several applications from the tins. So several years worth.

I copper plated my prop this year. It will be interesting to see what the state of it when it is next lifted out !

That's interesting. I did mine several years ago, wrote it up in PBO, published last year. Due to illness and other problems the boat was in the water for two years and four months without moving. Prior to that the boat was in a drying berth for six months, prop not cleaned after that. At haul out the prop was remakably clean, just a few barnacles. The hull was heavily fouled with mussels (scraped off in the pic).

Hi Viv,
I asked on the CA forum last year when contemplating the idea and you very kindly replied about the PBO due out shortly. I used the same company and very pleased I was with the help, service, delivery and price.
I will try and remember to take photo it when it comes out again so we can compare.
