After removing a few bits of engine - alternator , water pump, and other stuff, I could just see the broken bolt in the block. ( if I stood half upside down in the adjacent lazarette) but I got a pair of mole grips on it and "WHOOPEE" it turned and I was able to remove it.
There was a bit of collateral damage namely a small gash to the bonce.
Anyways this is a great step forward, No expensive engine removal and both mounts are now out , nnuts and bolts on order and once they arrive I should be able to get it all back together.
May be able to afford a new mainsail now I've saved on this.
