Anode wear on Volvo TAMD63p engines

[Thepipdoc]

Is the rate of wear to the anodes on the Volvo 63p engine similar to that of the anodes below the waterline? i.e. 12 months and they will be worn, but have a little life in them or do they generally last longer than 12 months?
I realise this is a bit of " how long is a piece of string" question but in general terms how long should they last?
Are they easy enough to fit? Is it necessary to drain the seawater from the engine prior to removing the anodes or will I be able to remove one at a time and then replace it with just a little water seepage? ( I'll close the sea cock before removing anything of course)
Thanks

See the owners manual.

The service schedule recommends checking them every 250 hours or at least every 12 months

The procedure for changing them is described in the manual too.

If you have mislaid your manual you can download one from http://www.volvopenta.com/volvopent...lication_search/pages/publication_search.aspx

Every 6 months depending on the level of electrical activity around your boat , I often find then gone after just 6 months in areas like port Solent and ocean village.

Simple enough to swap. I put a bit of Loctite 577 on the tapered threads. This still allows the essential electrical contact, but keeps the thread clean for next time and stops any leaks or furring. I would avoid PTFE tape as this could insulate the anode making it useless. A fistful of tissue will collect the water, but closing the seacocks is a good precaution.

Thanks All.
Changed them today and all was well.
About 25% left on them so timed it about right.
