Is this Propeller Servicable?

[sailorman]

Don't move it too close to the P bracket as it will restrict the flow of water through the cutlass bearing. IMHO

No it doesnt but allow enough space to de-couple the 1/2 coupling

There is no anode on the prop. There should be one that fits onto the nut, which is what you can see, held in place with an Allen screw into the threaded hole in the end of the nut. This sort, sometimes called a Beneteau type. http://www.mailspeedmarine.com/anodes/plastimo/conical-shaft-nut-anodes-1280-128317.bhtml

Yes, but it is there as shown on the photo. That is why I am asking why it has not eroded as iyt does not look new.

There is nothing wrong with the location of the shaft anode. It is electrically connected to the shaft and in view of the prop, so should work.

However, requires a minimum of 20hp to make it work, and the OP only has 9hp from his engine. Nothing wrong with that 2 blade fixed prop for under £300! If he wants drag reduction under sail then a basic 2 blade folder would be the logical choice.

I'm told that a Darglow Featherstream also goes down to 1GM10 territory. It's the only non-fixed type which will fit my boat, so I'm saving up. OP clearly doesn't have the same space restrictions though.

Yes. I had one on my 1GM and it does the job. Retained it when I changed to the new Nanni. You really need the 3:1 reduction so you can use the 15" version, but then you might get into difficulties with clearance in the aperture. Talk to Chris at Darglow to get good advice.

No, what you are looking at in the photo is the nut. The zinc anode (as per the link) fits over the top of the cone on the nut and is held on with an Allen bolt into the end of the nut.

Yes, you are right. Looked at it too quickly. Perhaps the lack of the nut anode is the reason for the dezincification.

Rebuilt my prop twice, lots worse than that. Send it, they will soon say if it's gone too far.
