Thanks for this but it’s the prop shaft nut thread I need to check. The M8 thread inside the nut holding the anode has stripped, probably when I picked up a builders 1 ton tote bag round the prop.
Great, thanks
There is a tab washer, which doubtless will break when I unbend it. Only a month of the season to go so I’ll do the best I can to get it all secure, if I can get the nut off, then check everything when it’s on the hard. Maybe a good opportunity to get the prop refurbed and an inch of pitch taken off.
Hopefully you have done it now but yes, anticlockwise to unscrew. 41mm AF spanner. https://www.ebay.co.uk/itm/Laser-To...-d373bf22acf7&epid=2222164355&redirect=mobile
Thanks for that, still awaiting the hugely expensive nut from the Anode Outlet. I’ve got a couple of very big adjustable spanners which should do the job and give plenty of leverage, just a really crappy and tight place to have to work to get at it
I might well do that when I’m not crawling around under the boat in a stinky harbour with the tide threatening to inundate me
Providing the nut comes off ok 10 minutes should see me done and dusted with new nut and anode in place 
Builder’s bag around the prop probably did the damage.
The most difficult part was actually unbending the tab washer, also hadn’t thought through the prop not being locked by a hydraulic gearbox although a quick tap with a lump hammer on the spanner got things moving…
Yes, the nut and anode came as a set and the anode didn’t spin when loose. I’ll now helicoil the old nut so I’ve got a spare (hopefully not needed) for the future.
