Here's my FeatherStream with the flat anode. No modification to the rudder needed.

Many thanks Andy. This is very useful! Actually, I was looking at the prop this very afternoon (under the rain!) And taking measurements. Will get in touch with Darglow again and review options.
The boat is on the hard in Brest at the moment. I may have to take the engine out. The mounting bolts have worked themselves loose form the grp cradle. Probably need to be cemented in again. Then would be a good time to change the prop and (perhaps) upgrade the engine too. I don't know how easy/hard would be to do that here in France, but needs to be done!
Thanks again

The only wrinkle is that you have to take the rudder off to change the prop - but not to change the anode! ;)

I have original yanmar 2qm15 13 hp motor.
I have no problem to cruise at 5.5 knots with max just over 6 knots in ideal conditions.
Not sure about prop size, it is two blade, I believe original one.
