No. And something with a lot of arsenic in it would have been a good idea, albeit that is super illegal these days! Years ago bottom paint contained all sorts of toxic stuff.
As I walked to and from my boat today I was able to look at the lower units of several outboards and I/O rigs that are down in the water and saw the HORRIBLE growth from the sea water.
I have no idea how I will get that off my boat bottom! My lower unit is tilted up as far as possible but still extends only a few inches into the water. The marine growth after 3 weeks in that few inches is amazing! So today I looked at the growth before and after an hour ride in the harbor. I kept the speed up over 20MPH most of that time and hit 30+ for a few minutes. Guess what? The marine growth was exactly the same, NO change! So simply erosion from the rushing water is certainly not going to remove that.
