The boat I'm looking to buy right now has no zincs, since it's in the fresh water. It's a steel boat.

I need to add a full compliment of zincs to the boat to prepare it for salt water. It's a steel hull.

How does one go about this? I often see zincs on rudders, keels and of course on the main part of the hull. The main part of the hull makes sense to me - drill hole, use backing plate and bolt on, bedding with 5200 from the inside to keep water out.

The rudder and keel attached zincs aren't so clear to me. Do you drill holes and then tap threads into those holes to hold the annodes in place?

Anyone have any tips for doing this project?

For those following the story, we are looking at buying our junker now, before our Gulfstar Hirsh sells so we can move off the boat and have it ready for showings at all times. A little more expense, but maybe a LOT less headache.
