How many zincs on an exposed shaft?

We need to replace the zincs on our new to us*boat before we relaunch, having had her stored ashore since we purchased last year.* The existing zincs are not really worn enough to replace, but then we hope not to have to lift out again for some time so it would be silly not to use the opportunity to change them.

*

My question relates really to the shaft anodes and*we have two shafts each with two anodes fitted at present which are not even half worn away.* I have ordered 4 new anodes (plus all the others needed) but I'm wondering if we should just add an extra new one to each shaft and leave the existing ones in place as well?* Would 3 anodes per shaft cause a problem, or even four if we put all the new ones on?*

*

Same with the big flat 12" x 6" anode on the transom, if there is enough bolt space is there any sense in adding the new zinc rather than just replacing it with a new one?

*

I hate waste!
