How about carefully drilling and tapping a few screw holes into the casting and then bolt the preshaped aluminium patch down over some JB Weld etc. Put Duralac or some similar isolator product on the bolts if using stainless or if you want to do it better thread up some marine grade aluminium bolts instead.
