My Boat has zincs one on each shaft and no other location. I've been hearing this a terrible location because it can and will unbalance the shafts and propellor I just balanced. That they should be bolted to the back of the transom or on the trim tabs or on the rudder (rudder sounds bad to me). Please sound out where yours are located and issues you've experienced.
Zinc Location for 3207 Aft Cabin

We have a 1983 3207. Ours are on the rudders, one sandwich on each rudder, about 3" in diameter. They're shaped to be pretty aerodynamic, flat round domes. That's pretty common actually. Here's an example:

I have them only on the shafts (one each). We are in fresh water only and have been using magnesium anodes instead of the zinc. Zinc can be used in either fresh or salt water, but magnesium only goes to fresh water. They are a quarter of the weight of a zinc anode, extremely light and won't really impact the shaft at all.
I have a 3297 Mariner, and from the looks of things, there isn't any place else that had them previously installed.
kthoennes: how does that fit on your rudder? Do you have a hole through it where the screw goes through and then those zincs on either side of the rudder?

On the shaft is Carver's normal location (among others depending on boat). Just make sure that the anode is closer to the strut and the balance issue will go away. We put them around 2 inches ahead of the strut. There should also be a big anode plate on the transom. Although I don't remember what year thaey started putting them on.

When I took delivery of my boat it had zincs on each rudder; three on each shaft spaced equally apart plus one on each prop nut; and zincs on each trim tab. I've been replacing the zincs with this same configuration. Didn't know about zincs causing shaft balancing issues. Why do they make them specifically designed for shafts then?
