Thanks for the fast replies.. Ive been rebuilding this boat for the past year and so now grumpy with the past owner for letting this happen!!
Anyway - I have 2 x cracks near the thermostat housing at the neck. And another two at the same end on the face of the head..
Still establishing if we can repair locally, but so far most machine shops are reluctant to touch it..
I shall contact Industrial Engines - thanks so much..
Seems also these EBRO FL engines are fairly rare!
