Changing Annodes ??

[rivonia]

To change the annodes on my saildrives I have to remove the prop. Is it possible to do it under water? The reason that I am concerned is that so far I have always insisted on Loctite being put on the screws.

Thanks in advance

Peter

Hi Rivonia,
I have heard of the props removing themselves with no human intervention!
If the water was very clear and you used a large bucket under the work area, it might work.Any chance of standing on the bottom or say hard sand whilst working?
The manuals say to use a new bolt and washer on the dome part.I suppose you could apply the locktite to the bolt and cover with snappywrap until ready to insert.
Perhaps you have the split anodes?
Then it should be simpler?
Are the props standard VP alloy two blader or something even more difficult to remove?
With a bit more info others will emerge to advise before long!

Thanks for your reply, was expecting more imput from the techies. It would appear that I will have to haul out-pity. I was going to use a diver as it would be much cheaper.

It is not really a "technical" job. It can be done underwater by a diver who knows what he is doing. The potential problem is losing the bits when you remove the prop and anode. You need to replace the locking bolts in the prop.

Would be much easier with the latest 2 piece anodes - not that it really helps you if you have 120 drives!

I've done this on my own boat and for others a number of times. I have a Brunton autoprop fitted which has about 5 allen screws and a main nut before it comes off, then there are the 2 screws retaining the anode on the saildrive leg. Takes me about 30 minutes to do the job and I hang a bucket off the leg so as to catch the bits I drop....

Never had a problem with things coming loose, either with the Brunton (difficult to imagine it working loose with everything locked by yet another allen bolt) or with the more normal single allen bolt locking the main prop nut.

Many thanks for the replies. It was very helpful and now I shall seek an experienced diver who knows what he is doing. (especially the advice re the BUCKET)

Cheers all
