Yes that is the bolt I was speaking about . I never knew what that black stuff was for a number of years and when I did I immediately dug the silicone out and the bolt was surprisingly loose. It looked exactly like yours. If you get to warm water you could dig the silicone out. Remove the bolt grease it and put it back with grease. Then crank it down tight.
I would ask Olivier, however I feel you could sail without silicone for a while.
Where are you?

Thank you all for the info. I should have mentioned in my original post that we have a fixed propeller (I think its the original spare). I'm a bit concerned about this domed mastic thing... depending on how you define "domed", it may have been in such a state when we last hauled out. I've attached a photo. What do you think? We're no longer in the tropics, so it's too cold and too murky to go down and look at it now.
What purpose does the mastic serve? Would it be harmful to remove it in the water and not replace it? Presumably the rest of the bolt is exposed to seawater, so I don't see why the head needs special protection.
