Removing the Garboard drain plug

[speakrdude]

If, and that's a big if, I can get the three Phillips screws out of the Garboard drain plug on this 88 300 DA, will it ever come out?
Is it most likely epoxied and sealed in there? Same scenario with the bronze thru hulls, although, I believe I have a better chance of removing them.

I was wanting to do a little gel coat repair and clean up the brass/bronze, before I apply the new bottom paint. Around all of the brass/bronze/stainless products that were in the salt water, the gel coat surrounding them have cracked and chipped. Most likely due to an impropper grounding solution?

My moto seems to be, "If it ain't Broke, Break it!"

The gelcoat cracking-assuming it's in the neighborhood of the screw/bolt holes, is usually due to an undersized pilot hole and/or not chamfering the outside of the hole after drilling. It's always a good idea to chamfer the outside of any holes drilled into glass/gelcoat to minimize spider cracking.

I don't think are stress cracks. They really look like something else. Maybe it age related. These all had lots of bottom paint over them. This seemed to happen anywhere there was metal under water. Brass, bronze, or stainless.

I have dremel'd out the chips here.

All dremel'd out and Epoxy resin with thickener filled.
