2006 AJ 290 Longest season in the water since I bought the boat new in 2007. We pulled and blocked the boat yesterday. Pulled off the outdrives and brought them home. I spent a lot of time last year trying to get traces of barnacles off the props. I think it will be much quicker to use my sand blaster. What's the best media? Sand, ceramic, shells ? There's no sense to get a polished finish.. So same question for drives to prep for new coat of etching primer and Trilux33... Thanks!
