Propeller antifouling

[Norman_E]

OK I know I will get wise cracks. I did the last time but my boat is a Kelt .8.50. I have used cow's udder grease for over 5 years with great results and have only used less than half the tub. Let the wise cracks begin. I am the one laughing because it works and only cost a few euros.

I used Lanolin on a new MaxProp and it certainly worked for a time, but with the boat in water for two years the prop was fouled by the end, mostly with the hard white "worms" which dissolve if attacked with a fairly weak acid.

Looking for recommendations.
What works, what doesn't?
Prop is a 2-bladed Maxprop.

I know it's an old thread but always relevant. Has anyone tried hard antifoul over some suitable primer on their prop? I've seen several self polishing products but why not hard AF?

EWOL steel prop.

I use lanolin applied with a heat gun. I get the prop warm so I can only just touch it and smear the lanolin around generously. I suspect this is in the same category as cow's udder grease.

It works well enough. I spend time polishing the prop up to 1000 grit with a little drill-powered sanding device. I'm not sure it makes much difference but it does look nice.

Velox applied as per the instructions here antifoulingpaint.net widely available from UK chandlers - and it works.

My prop is a flex o fold 3 blade. I use Hammerite Special Metals Primer then Trilux. Seems to work reasonably well. At the end of the season, I put the prop in a bath of brick cleaner for half an hour and it comes out nice and shiny. Quick rub down with 80 grit to key ready for primer.

We were lifted out after 24 months with little movement because of Covid. A naked prop and very little growth. A quick clean and a scrape and as good as new.

The blades on my Flexofold 2 blade are now in their third season since Velox Primer and top coat. Lifted 2 months ago after 9 months in and light slime washed off. First photo last June after over a year, second 2 months ago.

Highly recommended. Preparations is key. Cleaned in brick cleaner, abraded, primer and top coat applied as per the instructions posted earlier.

I’m in a similar position to the poster who didn’t want to despoil their shiny new Featherstream but 3 years on that’s faded somewhat. I feel that 80 grit is ok for bronze but too aggressive for the stainless steel blades of the Featherstream. I have a choice of several year old opened tins of Velox or Trilux to go on top of Hammerite primer so it’ll be which looks in best condition

Velox Plus is still available from some chandlers who have stock, but it's technically no longer for sale in the UK due to COPR issues.

Anyone used silic one?

Did not know that. Glad my little pot is a lifetime supply for me!

I used it a couple of years ago. In spite of all the care I took there was none left when I lifted out. I am trying Trilux this year and walking around with my fingers crossed.

I've been using Trilux for a few years, with the boat staying in the water for a full 2 years between liftouts. It was lifted last week, and there was some fouling on the saildrive, probably to be expected as the boat's hardly been used in the last year. The yard guys didn't think it looked too bad in the circumstances. Here's what it looked like before power-washing.

Velox plus works.
