Need to re-attach seat PICS ADDED

[dca2]

I have a 2000 Triton SF18. Passenger seat pulled away from the deck. I was surprised at how it was fastened -- 5 lag screws with fender washers driven through the seat base into a "deck box"? that is fiberglassed continuous with the deck. It appears to be the height of a 2X4. Only the front screws pulled out (i.e. stripped the holes)

I would like to put the seat on a swivel to make it more comfortable to watch water skiers.

I have not found access to the bottom of the "box" for using bolts. I am thinking of getting a Springfield locking swivel and lag screw it back to the box. It would use different holes. I hate to use lag screws, would heavy duty mollies be a better option? Is there another option?

Thanks,
Dave

a picture is worth 1000 words.
you can up load to a free service like photobucket.com then you choose the pictures you want( clik the little box at the bottom left of the picture) scrool to the bottom of the page, clik generate html, it will take you to the next page, scroll down to thumb nails clik on that and copy, then insert it into your post.

How about a couple thousand...
Here is the "box" that the seat was attached to. When I move some of the carpet, I can see that the box is glassed over continuous with the deck (Coke bottle for size reference):

The "box" and the seat from overhead:

Seat, overhead, small holes are where the screws went through and down to the "box"

Screws that screwed my seat:

The front of the seat (towards the bow) is where several of the screws pulled out. I removed the rest with a screwdriver--they were holding very tightly.

And you want to put in a swivel plate between seat and box?
Well then I would suggest you cut a hole in the box at the center of where the swivel will be. Just big enough (as in a very small hand or couple of fingers) to get one of these to the bolt holes needed for the swivel.
Install these from the underside of the box top. Draw them up into the box and final position with a bolt from above.
Then bolt in your seat with SS bolts and anti-sieze.

i agree that is the best fix.

Thanks for the help!

Do I need to worry about water collecting in the "box" when I cut an access hole or is that going to negligible? I normally keep the boat covered but it is outside.

Is this normal construction? Seems pretty cheap and crappy for a decent boat.

very normal, just a plywood box, if not stable enough for he pedistal, a cheap fix, is to remove the carpet on top, set a piece of 3/4 exterior plywood on top, drill you holes for the t nuts, install them into the box. paint the plywood piece to match, place the plywood on top sealing with PL poly construction adhesive, mount the pedistal on top, thru the new piece. this give a firm base for the pedistal.
