Outdrive antifoul - Black or grey ? Is there a performance difference.

[Meagain]

Hi all, our new to us boat came last season with black antifoul on the outdrives, casual observations while walking down pontoons suggest grey is more popular. Is this just a choice or do we believe there is a fouling performance difference? Having just lifted I have been surprised by the amount of tube worm (Hamble/Poole based) on the drives so has got me thinking. Views appreciated.

I did read something on here recently where a guy said he noticed white antifouled hulls appeared to last longer than other colours !

Just a word of caution… Please read the tin thoroughly! Some manufactures black antifouling is not compatible with outdrives … whereas the same “named” tin of grey is…

I imagine there is a performance difference based on the type of fouling you experience. I noticed on my boot top different colours attract different growth types. Black for a green filament type weed and white gets a brown diatom slime. Barnacles go where ever they can stick and mussels just love intakes, thru hulls and deep crevasses where I am.

The guy that anti fouled my boat recommended using black as it works better than the lighter colours. I don't know if it does but time will tell.

Thanks for the feedback, guess I will stick with black for another season then compare with others, as its really the tube worm causing the problem rather than slime/weed. In the meantime I will check the tin wording .

Went white once, looked great for a month or two so now black everytime
So what if your canopies are blue? The anti foul is under the water!

My outdrive is painted white and the props black, much better than when it was all grey, but I suspect that's more to do with changing brands from trilux to Seajet.

Usually white\grey for Volvo and black for Mercruiser but its all a load of crap in my experience!
