I have Barnacle spots on my lower unit that I cant get off. I've used 100 grit sand paper that didnt work, I alod tried a wire wheel which works but scratched the heck out of the unit. Anyone have any suggestions.

Thanks
 
I think On-Off will take them off, if not muriatic acid from the pool place definitely will. However both products are bad news and will also eat metal. Use VERY carefully and rinse thoroughly.

Alexandr's suggestion is the safest.
 
Do you use an anti-fouling paint on the drive? If your not you should, I'm assuming you boat in saltwater. As far as the barnacle base it will come off with a scraper but if you trying not to scratch the original paint finish use "On Off". The stuff is good but do not get it in any open cuts on your hands or you'll cry like a baby. Also rub it in with a rag then scrape it with a plastic scraper.

Yup... On and Off, or muriatic acid will remove them. I use the later because it costs so much less and works as well or better. As mentioned, don't leave it on the metal too long. Also, you will need to hit them twice. I use the acid and a plastic scraper. The first pass gets most of it, the second pass gets the remainder. Don't breath the fumes...
