Ok, getting ready to paint the bottom and replace the anodes tomm. My boat came new with a "zinc" on the armstrong bracket (05 Parker 2520). What type on anode should I use ? The one there now (factory installed) looks like a zinc ? I dont think that zinc provides protection to aluminum ? Also should I seal the anode so water dosen't enter the bracket ? Won't that make it non-effictive ? One more question, I bought outdrive anti-fouling paint for the part of the bracket that is in the water (in a can, by interlux), Is that the best paint to use ? Thanks all !!
