I have just purchased a Hardy 21' Motorsailer which has been out of the water for a while and has no obvious Anodes. Could someone advise as to where and what size I need in attaching new ones.
I wish a Very Happy New Year to you all. I look forward to meeting members in the Christchurch area.

Whilst Steve's comments were most helpful I am still presented with the problem of completing the circuit within an extremely confined area. To gain access to the stern gland my only option seems to be to remove the fuel tank & cut an access panel through the marine-ply floor directly above the stern gland, a hammer to crack a walnut springs to mind....
Despite requests Hardy Marine have not yet come to my aid. Thus desperation is setting in, radical ideas include attaching a 180 degree stainless steel sleeve to the good end of the now separated earth line and placing this over the prop shaft whilst not under way, brilliant.....
Risky indeed due to the physical exertion and possible damage to one's precious bit's whilst completing this process, combined with my memory recall & other senior moments a sure recipe for disaster, remembering that the removal and re-placing of said sleeve is required prior to and after each sortie.
So a more permanent and less hazardous option is still sought ''PLEASE''.

Although the ground wire has come adrift, and ideally should be replaced, it may well be that the shaft is also earthed via the engine itself. Why not check the continuity as Steve suggests. If the Mariner has a flexible prop coupling it is quite possible to bridge this, in fact some have straps on the bolts for just this purpose. Might temporarily save your bits!

''Whoops'' My error the fuel tank is of course located directly above the offending stern gland/stuffing box & not as I indicated below.

It most probably has come off the stern gland and should be re fastened to it to offer protection.
It is quite easy to check out the Cathodic protection circuit using a battery and a bulb in connected together in a line of wire. Simply attach one end to the anodes under the boat ( If out of water )or one of the boats anode bolts in the hull if in the water. then touch the other end to whatever you wish to check if it is connectecd onto the cathodic circuit, and if your bulb lights it is. Good to check the drive shafts, props, seacocks etc etc,if connected, etc etc and check your protection system is working.
Hope this helps.

Cleaning a flooded engine room recently a cathodic system wire (pale green) came adrift from the area on top of or around the stuffing box/stern gland area.
If my memory serves me right this wire was attached to somewhere on the stern gland, can anyone tell me where or offer an option for effective re-location?
Sited directly above the fuel tank the area is very inaccessible to all but a champion Chinese, gymnast, so sensible manoeuvering solutions that are realistic to a mid fifties stoutish un-supple bloke are appreciated.
Nightmares of my prop fizzling away taunt me, as does the £600 plus cost of re-placement.
