I was about to suggest heat from a butane torch (my favorite boat tool) when I read the above. I believe if the heat is properly modulated it could help.

I used heat on the mounting plate for my mast mounted halyard winch, which is made of aluminum, to remove the stainless steel screws, which were threaded and frozen into the aluminum plate.

Initially I could not move these screws at all. I tried PB-Blaster, and a #3 phillips bit in my Milwaukee cordless drill.

I finally safely removed 4 of the 5 screws (number 5 was already buggered and snapped) using heat... #5 came out with the liberal use of a ball peen hammer.

Try McMaster-Carr, I don't thnik the head crss vs straight really matters. They make it with an allen or torx also which may be much easier to extract down the road.

Since one of the screws came out with just (correction: a lot) of arm muscle, I'm hoping the other three are just being stubborn and a nudge from the impact driver would move them along. The risk, of course, is that the screws might break at some awkward point as dictated by Murphy's Law.
I tried the impact driver as well, the problem is the bolts are so long they twist, absorbing the force of the impact over their lengh. I had a mate push down on the screw driver with all his weight and I turned it with a wrench across the blade. I managed to twist it 180deg before the blade slipped.

Re: Dislodging Edson pedestal bolts

I had to do mine a couple of years back. Mine where not bolts but countersunk flat head 1/4" machine screws 6" long as I have an extender ring for the compass and engine controls. Drill the heads of, start with a very small pilot hole then a 5/16 drill to take the heads off. Invest in a good sharp/new cobolt drill, go slow and use cutting grease, don't get the head hot as it will harden and you will need to do something else. When the heads are off lift off the bezel you will now have four 1/4' pins to get out, I found a small pipe wrench worked best. WARNING WARNING do not apply any form of heat to the bolts as the pedestal is cast aluminum and will disintegrate.

Re: Dislodging Edson pedestal bolts

Lots of interesting advice. Thanks to all. An approach that I might take based on some Google searching is to use a Dremel to cut off the bolt under the sleeve, exposing the shaft of the bolt above the threaded area, then use a pair of Visegrips to twist out the bolt. Apply elbow grease, prayer, and appropriate cuss words--in random order. I'm not happy about the thought of drilling out the bolts! The threaded sections are about an inch or more as I recall. I'm also concerned about one of the posters mentioning that the bolts might be NLA as its an older unit (at least since 1983).

Re: Dislodging Edson pedestal bolts

Mine spun out - they had a square nut on the bottom that just fell down inside the pedestal. I replaced them with brass screws that look better and will remove a lot easier.

ECS-IB30 Drill and tap them if they wint come out. On my ib30vone came out, and one broke inside...I drilled the heads on the remaining bolts and used vice grips to finally get them out. I re-tapped all of the holes as I reassembled. On my boat the chain had snapped and I bought 19 feet of replacement chain from grainger...much cheaper than Edson...good luck
