Silly me..!

You can through bolt them, as I do, or drill & tap a fiberglass backer block or drill and screw some bronze lags into the marine ply backing plates. Be sure to use bronze bolts, screws or lags for "securing"!!!

While screwing is not as strong as through bolting it is still MUCH stronger than what you have now and perfectly acceptable if you're not comfortable with a through bolted installation..

Through bolting prior to fairing the holes over...
