Shame on me. I backed into a rock is shallow water and damaged my prop. Prop is off and being repaired. My question is, what's going on around my aluminum anodes on the rudder and rudder shoe ?
After being on a salt water mooring for years, this season, I moved to a fresh water slip up in a river. As I mentioned, my anodes (divers plate, rudder, rudder shoe, and thruster), are all aluminum. I've been plugged into properly grounded shore power, with Xantrex battery charger running 24 X 7 for the last 2 months. I have a Charles battery isolator, and I installed a ProMariner ProSafe galvanic isolator. For the past couple of years, I've been using Trilux 33 bottom paint on the prop, rudder, and shoe. With winter and rain runoff, the river water is the color of a strong tea, therefore the stained color.
When I hauled for repairs, I noticed the Trilux 33 was relatively soft. Expand the photo and look what's going on around the anodes. The Trilux has flaked off. Prior to using the Trilux, I painted hull, rudder, and shoe with Pettit's Hydocoat, without any issues. I've striped off the Trilux, and I'm going back to repainting the rudder and shoe with Hydrocoat (other than water stain, hull looks good). I will spray the bare prop with 3 light coats of Pettit's 1792 Zinc Coat Barnacle Barrier. Is this deterioration some kind of Trilux and fresh water reaction?
