Zincs on aluminum boats
I haven't been paying too much attention to zincs since I bought my boat. In doing some reading, I think I should change my ways. I have a zinc on my outboard, but none on the aluminum hull. My engine mounts to the transom over a rubber vibration-reducing mat. Where should I mount any anodes on the boat? I'm a little tentative about drilling holes in the hull. Should I be concerned about anodes slowing the boat down at high speeds? Thanks!
