Tightening Starflite seat bases

The front seat bases in my 88 Starflite don't seem to want to stay tight. I can tighten up the seat base bolts and they seem to stay tight, until we take the boat out that is. Over the course of the day, they loosen up. Any suggestions to tighten these up? The floor and seat base boxes are rock solid (thankfully, so is the entire boat thanks to diligent previous owners).

My first thought was to remove the seat bases, fill the old screw holes with sealant or epoxy, rotate the seat bases 20 or 30 degress, then drill new holes and use lag bolts to bolt them down.

Does anyone know if the seat bolts have backing nuts under the floor? I appreciate any suggestions, I figure enough of you guys have restored Starflites and Starliners to make this seem like a pretty small problem.

Thanks!

Jeff, from the factory, the seats are T-nutted on the underside. I used lag bolts on one of my Pulsares when the driver's seat wouldn't tighten back up. Like you said, make sure you seal the holes real good.
Good luck-
 
As SCT said in the above post, Checkmate used Tnutz in the floor. With age and corrosion the Tnutz can get stripped out. You may need to drill out the Tnut and replace with a lag bolt. Make sure you seal the hole with a good sealant to prevent moisture from seeping through. If you still have good threads on the Tnut in the floor you can try using locktight to secure the bolts..
 
Thank you for the suggestions! I'll try loctite first and see if they hold up. I've been worried about completely removing the bolts in case the nuts fall off the back side. I believe only one of the bolts feels "stripped out" so maybe I'll get lucky on this one.
