VP S130 sail drive / 3 blade fixed prop - painting

[send54sail]

Hi there,
I have found a bewildering amount of detail on this but grateful for (hopefully) a very simple steer.
1/ According to the old receipts, the sail drive has been antifouled with Trilux 33 several times by contractors over the years but as far as I can tell it has never been primed except perhaps on the first occasion. Is there any need to prime it or can I now just paint over it with some more Trilux 33, presumably after keying it?
2/ None of the receipts say anything about the prop ever having been painted or antifouled at any stage but I know these VP props are supplied black and the prop now is exactly the same creamy colour as the saildrive so I guess it must have been Triluxed too. Basically the same question - should I add some more coats of Trilux 33 onto the prop, with/without first priming it?
If it is advisable to prime either of these areas, does Hempel Underwater Primer do the job or do I need something more specialist?
Thank you in anticipation!
Andy

I'd just repaint with Trilux.

I would have just over coated a sound clean dry surface without any preparation but the product data sheet seems to suggest high pressure water jetting or lightly wet abrading with 180- 240 grade paper..

I use Trilux 33 on saildrive and prop, other antifouls are available, the important factor is to use a non copper antifoul, since your saildrive leg is aluminium, so would act as an anode for the copper and corrode:-(, with an expensive outcome.

The factory finish, or so it seemed to me when I got my present boat, seems to have been a light grey enamel type coating, baked on. Would have been followed up with Trilux Primer and Trilux33, the latter of which I have continued to use, with moderate success. If the existing a/f is undamaged, give it a rub down, wet, with medium Wetordry and apply a couple of coats of Trilux33
You are lucky that there is still a coating on the propeller, I suppose it says something about having it professionally applied, rather than a DIY job! Again, rub down and Trilux. Be careful not to sand down to the substrate.
