Repalcing hull anode - does this look right?

[Crinan12]

I am replacing my hull anode (which i understand probably doesn't do anything but I am replacing it anyway)

Can someone tell me if this looks right please ? On the mg duff video they use large square washers with sealant. Mine just has small round washers. Obviously I didn't have any leaks before and I will re seal them.

I suppose I am just wanting someone to say 'yes that looks fine' because I have never done it before.

I was planning on re using the original nuts and bolts that were there already.

Thanks

It looks OK except for the rust. Check the resistance between the anode and the object being protected. It should be less than 1 ohm.

The big square washers are usually affixed to the studs. Are they just on the inside of the hull?

When I replaced my anode last, I just replaced the studs too as loosening the anode had worked them free anyway…

No I dont have any square washers. It is just a bolt with 2 nuts and a circular washer on the inside of the hull and the same on the outside of the hull. Thanks

There is a reasonably good video on fitting hull anodes here ( they show the studs being fitted to the hull but don't say anything about the nuts etc on the inside!)

You will see the special studs with a welded on plate being used ( welded on plate on the outside ). They allow the anode to be changed without disturbing the studs and the internal bonding

You say it is probably not doing anything, but what is it bonded to ?

FWIW I’d be putting big penny washers on the inside of the hull.
What sealant did you use?

One wire goes to the stern tube and another wire goes to the engine.

I investigated this before and I don't think i am misquoting vyv cox when he said the hull anode probably wasn't actually doing anything and I could just remove the anode and fill the holes, which I did consider doing

I was planning on just using some CT1
