Lots of us use Velox in the Med.
Seems to largely stay on for the year and eradicates all fouling where we are.

Just to clarify
You use Velox on the SS props as well as the outdrive.?

Yes, on my stainless steel props. Quite a few of us Med boaters use it (JFM, Bart, Vas to name a few).

Thanks I’ll give that a go next year
How many coats and does one 500ml pot do both duo prop sets?
Do you need to sandpaper rough up the SS props before applying?

Interesting I thought of this as I used to use an IKEA bag on our 150hp outboard that would not lift completely and that worked well. However, I can’t reach my outdrive due to the bathing platform. I currently reverse into my pontoon mooring at Cobbs Quay which is facing approximately S and not much movement of water. I wonder if I went in bow first so the stern/outdrive is facing out into the passageway between the long gangways where there is more movement of water and facing North might be better.

Was the Hammerite Special metals primer the red colour? And what colour Velox on top? Was this spray or hand painted? Thanks.

All painted, red primer and black Velox - as per the instructions.

Boats on pontoons at was what Holyhead marina for about 17 years.
DPS Stainless props kept pretty clean, but the aluminium hubs needed antifouling.
DPH bronze ( a copper containing alloy) props, awful fouling !

Check out the Practical Boat Owners forum, a thread on there where they discuss copper coating props. Probably bronze props but still an interesting read.

I'm on a shaft drive and my prop never sees sunlight. When I lift the boat my prop has little to no growth. A small bit of slime maybe but no weed formation. Maybe parking so the outdrives are in the shade may help?

For me, that's not really possible.
I did look at the boat opposite that has their stern North-facing, and the outdrives there also look like something from a Pirates of the Caribbean film, and not in a good way, apart from that the vegetation looks to be slightly darker.

Ok so if we believe it is a sunlight problem causing the props to barnacle and foul up what about fixing a tarpaulin on bungee cords from the pontoon to my bathing platform so the sun can’t get to the props. I’m normally backed in. What do people think.

Bound to help but I doubt that it will stop it altogether.

Well it certainly won't hurt to try. Not sure you'll cure the barnacle issue, but should help to prevent the rapid weed growth.
I've noticed more of a beard on the side of my boat that's in the sun compared to the side that's against the finger pontoon and in the shade!

Also, a decent snorkel set up and a scrubbing brush is a worthy investment for mid season or bi monthly scrubs

Already do that in July and August

So looks like the following:
1. Cover outdrive and propellers with tarpaulin when on pontoon.
2. Try and scrub more often in season over the side in the water
3. 50:50 as to whether leave highly polished or Hammerite Red special metals primer and black marlin velox antifoul.
not sure what else I can do.

Sounds like a plan. I have a semi-D hull and a bronze prop. It too fouls but I just pop a mask on and go down to give it a scrub. It doesn't take very long. I use a green nylon domestic scouring pad, rough enough to take the fouling off but soft enough not to harm the prop.

I use industrial white scouring pads when cleaning in the water. I also do the outdrive, depth transducer and speed log wheel as well at the same time. Being a planing boat any growth on the propeller, leg etc makes a massive difference to performance and running costs. Sometimes can cut my speed down by 50% and double fuel costs which is crazy. I think semi displacement wins out here.
