Captains Chair On Teak How Is It Attached

[zoomer0056]

I have removed the captain's chair and pedestal to put a new pedestal in. The pedestal was very secure, just corroded. It was difficult, had to use upward force on most of the 2 1/2 ss bolts to get them out. I thought would be easy swap but I am faced with not knowing how these held the pedestal so securely. Based on how they came out it seems to me they were in there with just the same silicon as between the teak planks. I can push them in and there is no resistance, I am guessing there is no base plate underside. There was also a bead around pedestal base. As far as I can see, there is no access below the flybridge deck (maybe I can take down the headliner in the cabin). Does it make sense that bolts and pedestal were only held with teak silicon? thank you, zoomer0056

Not sure what held them in place, but I doubt it was just silicon. Ive had pedistals pull fairly large screws out of plywood floors. Would there have been nots and washers that dropped down out of place after you took out the bolts?

I think you've gotta be right about not being just silicon. I'll have to pull the headliner to have a look.

Update...there is/was backing plates under both captain's chairs. The bolts in both chairs were too short. Whomever replaced the pedestals did not engage the backing plates. One chair I drilled to 1/2" and inserted togglers because the backing plate must have fallen down. I am so lucky on the second chair. Using long bolts I was able to engage the backing plate. I'm wondering if there are nuts on the plate as one bolt spins but won't come out. I had to cut it to get chair off. Putting bolts back in seem secure by hand. I can see moving one bolt moves the others because they're in the same backing plate. I have to be careful, don't want thid plate to fall. It moves, but hasn't fallen. I'll see what happens when tightened down on new pedestal. That chair will only have six bolts. The picture shows togglers for one chair while other chair has bolts threaded into backing plate under floor.

Nice! New pedestals installed. One with togglers, the other with original backing plate. 3 1/2" bolts and 3M Adhedive Sealant 5200. Sturdy!
