I just removed an old school still working temp pick up thru hull from the Livesay. I drilled the nut on both sides as someone coated the threads with some type of hard sealer. After drilled to break the shoulders on bronze nut it flipped right open with a screw driver allowing me to push the thru hull sender right out.
So my question is and I'm leaning towards installing a thru hull mechanical plug if one exists instead of grinding and making a fiberglass patch plug. I could go either way cept the 5/8" hole is clean and might make a good future thru hull transducer location. Anyone have ideas on installing a mechanical thru hull plug ?

Yea so never mind folks, I did some online review and pretty sure I'm going to pinch it off and grind-patch then gel coat the hole.

Good choice. It's better to add a hole when and where you'll need it than leave one where you might not.

Yes, I figured out it would be best to fix it right today and be done with it just didn’t want to have to deal with matching gel coat etc.

Patches in place, turned out better than expected.
I did the standard dished and layered on both sides after a resin, chopped glass fiber and fumed silica mix to fill the 5/8" prepped and clean hole. I took my time and allowed plenty of cure time in between applications. Amazing how clear the finished patch was. I beveled just enough out to accommodate the layered transition. Now onto finish out and done.

Most boats are laid up with polyester in a timely manner where all layers are built up while the resin still in a liquid stage. Once cured, epoxy (1st choice) then vinylester are the recommended adhesives for repairs. I’m not saying it’s going to fail ( it probably won’t) but just know using the best is worth a piece if mind... especially below the water line

Yes, I did some additional reading on that yesterday and will likely grind out the small repair and rebuild with vinyl ester. It will still allow me to use my gelcoat and has better water barrier properties than the polyester. I know the patch will hold that’s not a concern. The boat is trailered and dry stored so water intrusion saturation leading to a blister on the patch is a non issue.

Nice Job your doing, it's going to be Cool...I dont know that I would grind out the poly to make it vinyl ester? There are many all poly boats still in service...should be fine...My 2 peso's
