Honda BF150 Cylinder head needed

[Full Race Geoff]

Hi everyone, I am new to this forum and to boating but heavily experienced with Honda engines (and turbocharging). My 6 y/o son is obsessed with boats so here I am. Long story short, I bought a motor which had a surprise. Hole in cylinder head caused by corrosion which I will now be fixing. Has anyone else seen this before?

And if anybody knows of a good BF150 head for sale please let me know !
