I'd inject some epoxy thickened with milled fibers into the mounting holes. Then re-drill them and remount. This will do two things for ya. 1) it will strengthen the mounts and give the screws better bite. 2) it will seal your core better from water intrusion.
I'd mount the console with either #12 or #14 truss screws. They look like a regular screw but the head is flatter.
