Shaft Anode

[RogerLloyd]

Neither by Konsort nor my previous boat, a Centaur, has a shaft anode. Hull anode, yes. Also the Konsort with a Bukh engine has an internal anode. I saw a Konsort recently with a shaft anode. Does it help to put one on?

I've got a shaft anode on my Konsort and it does wither away so I suppose it must be doing something......

I have a shaft anode on my Fulmar. It is relatively cheap to fit and certainly does waste away, so must be doing some good.

Anodes are relatively cheap items in comparison to propellers and engines that they are there to protect. My Fulmar has a shaft anode, Pear drop anode and of course an internal anode in the engine. I find the shaft anode erodes faster than the pear drop anode on the hull, probably as it is nearer the prop. I normally replace it every 2 years, but last winter I replaced it after 1 year as it was quite badly corroded near the fixing holes. I inspect the engine anode every year and replace it when necessary, which is usually every 2 years.
I would say a shaft anode is pretty much essential to protect the prop. Thinking about it, I haven't had to replace the pear drop hull anode in 7 years ownership. Maybe without the shaft anode that would do more work.

Thanks for your advice. Looks like I will be fitting a shaft anode. Thanks.
