Blown powerhead

Hello Boatmad - Advice is needed

My Mercury Promax has blown the powerhead.
I have pulled the cylinder heads off and cylinder 4 is gone, and the cylinder-rod (?) has made two very nice holes in the side of the engine block.
What could I expect to get from the engine in parts?
- I am not going to do a rebuild, but perhaps somebody is up to the task.

If anyone is interested here are some specs:
Engine is located in Denmark, hours aprox 250/h, standard midsection with exhaust, newer Torque Master Standard Rotation with torque tab, Alien cover etc.

(I can't seem to upload pictures, so send me your email for further pics)

Best wishes to all.
Sebastian
