My boat used to have an inboard with a saildrive, but as with most Leisure's it was taken out years ago and the hull glassed up and the hole filled in. Yet the anode is still there and the skin fittings are still bonded to it.

I have had to remove the bogs outlet for a overhaul. Its a Blakes type made by Simpson Lawrence. All went ok and I refitted it bedding on sikaflex.
Now the boat no longer has an inboard do I still need to bond the fittings to an anode. All the fittings, 3 of them, had a "fur" on them, inside only. I've cleaned this off. There isn't any degrading or loss of material, pitting etc on any of the fittings.
They all work fine and are free, yet firm. Do I really need to keep the bonding system?

skin fitting should not be connected to anodes
 
+1
Assuming these are bronze or DZR ( or even stainless) No.
They should not have been bonded to an anode on the first place

So I'll be safe cutting off the bonding wires and removing the runs from the boat. This raises another question as wether to remove the anode or not before it gets put in the water.....2 less holes in the hull. Could just leave it there until winter layup then remove it.
Thanks for the advice chaps.
