The way to drill and screw into a cored deck w/o leaks is to mix some epoxy and use a syringe to squirt epoxy down the hole before screwing. The wet epoxy lubes the threads while turning, giving a stronger hold, and the screw is encased in epoxy so it can't leak. The drawback is it's difficult to later remove the screw. I use a small impact wrench to remove epoxied screws.
