NEED HELP.. Hole in top of Cylinder Crankcase

[jcclub47]

Cut that corner out with a cut off tool and weld a replacement corner in there from a junk block. Then refinish by hand the mating surface to the head. Make sure to weld on both sides as one sided welds will fail.

Thanks for all the info guys. Much appreciated..
Only plus side is it's coming into winter here. So I've got some time up my sleeve to work on the boat itself and save some coin..
Cheers all👍

Pack the holes with JB weld then and reinstall the head with a new or the used gasket to finish out the season...

I doubt you could hurt your current investment that way and finishing out the season is like taking your beloved, aging dog to the beach and serving her a steak.
