Many thanks all, it's greatly appreciated.
Well, the plot thickens... Down there at low tide this morning, checked the thread, there's definitely nothing in there and the threads appear to be in good condition. Seemed logical to me that the very end of the thread must be damaged so I lopped 5mm off the end of the bolt (not easy stuff to cut, stainless steel!)
Reinserted the shortened thread, and exactly the same result.
So, the obstruction must be higher up on the bolt, somehow? it has a shoulder, I can't remember if the original did or not but it's possible they did supply the wrong one. Incidentally, the original bolt was a new one form keyparts with that part number, so the "correct" bolt did fit at some point.
Anyway, my marina neighbour wandered over and suggested exactly what Fred said below.
So, off to the Chandlers with the tide clock rapidly ticking to source a new bolt and/or washers.
The plan was to find a nut that fitted my bolt, then find a new bolt that fitted that nut. And, nothing did. It seems to have an odd thread, maybe it's imperial, it's a fairly old design outdrive.
Anyway, I grabbed some 8mm spring washers which fitted the bolt perfectly, flush with the head, as well as a few random other ones.
Got back down to the boat as the water was starting to lap the bottom blade of the prop.
Fitted the bolt with two spring washers, it only went in a few mm's but it tightened up firmly. So, unsure of how well the threadlock would work when submerged, I used a dollop of CT1 instead. That way, it should hold it fast (it cures underwater) but won't make it impossible to remove.
I'll check with keyparts that they supplied the right bolt, if not, I'll have a replacement to fit when convenient.
Thanks for the picture Fred, good to know that the shaft is a relatively easy replacement if it comes down to that.
I'll keep a close eye on it, but so far, so good!

Suspect it is going to be virtually impossible to get your drill central with leg on boat.You may end up causing more damage.
Why not for now get that bolt as far in as you can and using washers to take up gap between cone and bolt head .
Even a couple of threads and dob of Locktite should prevent bolt from coming loose.
Cone holds the prop on !
Just check from time to time that bolt is still in situ.
If you are convinced that any bolt is left in shaft, may be quicker and cheaper to keep an eye out for s/hand shaft and just get someone to swap the lot over next time you come out for A/F etc.
Only two bolts hold assembly in gear case, its just getting the correct shimming on reassembly that matters.

Towards the end of my love affair with outdrives, both of mine were held together with nothing more than sellotape a fair amount of silicon and a desperate hope that there was simply nothing else that could go wrong.
So.... any thoughts yet on how your next boat will be pushed through the water?

I'm very much liking the look of these !
