mounting pedestal to floor

Recommended Posts

I got a new old boat.it has no seats.I plan on mountin 3-4 pedestal seats in it.I see the Lil round recess mounts. Do they just screw into the floor and use a hole drill for recess? Do ya need to put another plate or somethin on other side of floor? Btw me and my bro are fat.looking for sturdy seats.gonna use the brushed steel? Or aluminum mounts with the golf cup hole thing

It would help to know what kind of boat, so we know what type of surface you're talking about. smile

all the sturdy boat seats have either an aluminum or steel plate under the floor, wood isnt strong enough for big guys like us. i put 1/8" aluminum under my boat floor for mounting the bases, and im pushing 300#

I did something similar with a 1980 fiberglass crestliner but added the 1/8" aluminum plate on top of the floor. Easier. Threw out the front/back facing run-about seats.

They would not hold in the wood without the plate to distribute the torque.

If you're going to poke holes in the deck of your boat make sure you use some type of sealant in each hole to prevent water getting into the wood.

Are they the type like this:

I didn't drill a single hole in the deck, instead I built up a mounting base shaped somewhat like a pyramid using 3/4 ACX plywood, cut a hole in the center for the recess, coated it in epoxy, attached it using thickened epoxy, painted with uv inhibitor paint, then secured it to that with stainless steel screws (with 3m 4200 in each hole) I also have small drainage holes in that pyramid base.

No holes in the deck = no water = no rot

You can somewhat see it in this pic:
