Q: I have noticed that on several motorboats fitted with ZD 78/72 anodes (including new ones) there is a shorting cable connected between the anode bolts INTERNAL to the hull. I understand this is supposed to promote even wear of the anode. My boat (2 x 72BM) has no such shorting links - should I fit them?

You do not require a link between the anode mounting studs, this will not help with even wear. The two bolt positions are purly for fixing the anode securly to the hull.
