Default Antifouling outdrive

What's the best treatment to prevent the build up of tiny barnacles on my outdrive? It's an Alpha 1 for what it's worth and I've had to remove the small water intake screens to clean them up, having discovered them to be almost totally covered over with these small barnacles. Is there an antifoul that is suitable for this sort of application? I wouldn't be tearing about the place at WOT all that often, but would the location and material have any impact? Everywhere below the waterline is covered in little barnacles. Any suggestions most welcome. Brand names may or may not help as I'm based in Ireland.

Trilux 33 Outdrive antifouling paint

You should also put some inside the intake screen area to prevent barnacles, etc. from growing inside the water duct. I usually spray a bunch down the duct and through the screen when I have the drive off for maintenance.

Do NOT use a copper bearing anti-foulant.

I have used Trilux-33 for quite some time but from what my rep was saying there has been alot of other service companies using Pacifica Plus.

I have never used Pacifica Plus because I don’t want a repeat season of Prop & Drive which did not work well in our area. We tried that the first season it came out.

Trilux 33 was acceptable but not the best which you can no longer buy. Trilux 33 can be applied wrong too.

Use any ECO paint it has no copper in it and will out do Tri lux 33 for protection. I switch over 4 years ago and zero growth on the metal plus the paint can be used for our bottom paint also just more money but not as expensive as Tri lux and you get a lot more paint for more seasons after you are done. I got tired of removing some small growth. I use the Pettit Hydrocoat ECO paint and I put two coats on all metal. Comes out at the end of the season like I just painted the brackets. Only draw back its not a spray have to brush on.

I retired a few seasons back. That is what the reps were saying about the econea paints. I was waiting for some other companies to be the genie pig. I know some paints worked well in one place then not in others. If I was still doing it day in and out I would use the Econea paint with a spray gun. We did that for a while using the 3M collapsing top feed cups and Trilux-33.

I use ECO also, twin alphas, 100% better that the trilux and other Aluminum spec paint. Also use on the props - different color...
