Yes, drill a hole or two and install the rivet. Only way to ensure everything stays aligned and doesn't shift if you go through and drill them all. I always start with the stringers and do the rib ends last. Put some tape or a stop collar around the bit so you don't drill them too far and hit the actual hull. Pre-mark the center location of your rib ends on the hull side with a sharpie(if going to get covered) or some painters tape so you know where they are after the decking is placed. I also mark the stringer locations with a sharpie line for ease of installation.Seriously, new holes sounds like the best way to get the new marine plywood attached. Here is the plan: drill a new hole for the rivet, brush the 3M5200 onto the rivet shank and bottom, push the rivet into the hole (some of the 5200 will fill the void between the new rivet and wood), attach pop rivet tool and “fire away!”. Wipe off all excess 5200 from top of flooring. Repeat as required.
I typically use a popsicle stick to spread on the 3M5200, and countersink my rivets in the locations where they will be walked on or may leave a small bubble under the Nautolex, then fill over with 5200 or MarineTex. Depending on what your plan is for the deck covering and installation method (covered rivets or exposed), you'll need to determine what is best for you.
