1983 Seafarer 226, seat pedestal base loose

I recently had some hefty friends sitting in the passenger Captains chair in rough seas etc. later, I noticed the base of the pedestal shaft was loose where it goes through the fiberglass. The pedestal shafts have the mounting plates inside the “fish box” fiberglass structure..., not sure what you call it.
I have access to the hardware through an inspection plate.... also, there is now a gap of nearly 1/4” between the pedestal shaft and the fiberglass hole.
My question is...,. Should i try to reinforce the gap in the fiberglass, or get a new pedestal base that would through bolt on top of the fish box compartment? All the new pedestal seat bases seem to bolt on top rather than inside.
Thanks !

Thanks,
I’ll take a closer look. The newer style base mounts that look like a flattened cone or flying saucer would be easy to install and perhaps more stable?
That said , the old ones have made in 36 years. Unfortunately, my buddies have gained some weight.

Will post pics Wednesday

The first photo shows the underneath mounting bracket/sleeve. The bolts were quite loose, so I replaced them and snugged them down, but this didn’t fix the pay in the pedestal shaft.

Number 2 & 3 photos show the pedestal shaft with the seat removed. The gap in the fiberglass hole is no more than 1/8”

number 4 is the sleeve of the mounting base with pedestal shaft removed.

number 5 & 6 are close ups of the pedestal shaft....

the mounting sleeve was holding water, so no holes, but had a paste like substance which I cleaned out.

the mounting sleeve has no bushing.
The pedestal shaft had fairly significant corrosion at the base rim. There was a slight step down from the top 2/3 of the shaft to the bottom 1/3 or so. There is a second very slight step an inch or so below that where the bottom of the fiberglass would be.

I could not figure out the manufacturer of the seat and pedestal.

for now, I’ll see if I can find a Replacement base and shaft.
If not , I thought about reinstalling it with some 4200 or silicone caulk. 5200 would be too permanent.
Either way, I’ll also let the core dry and epoxy the edge/rim and sand to snug fit with whatever I replace it with, or reuse old parts.
I dont think the newer style pedestal bases which bolt on top would fit. The shaft goes though the compartment to close to the edge.
Lastly, I’ll touch base with GW....

any help appreciated!

Leecoll,
Thanks for the input.
Did you replace the recessed base bracket , or just the shaft?
If you replaced either, did you get them from wise?
Thanks

Thanks Lee,
I agree.... going to try to adhere the existing post with JBW etc or maybe buy a new section of aluminum post if I can get the right size.
If it doesn’t work, can always remove it later.
