I've had this really strange fear of one day dropping my keel and having it just keep on going to the bottom of Puget Sound. To help alay some of this idiocy I got under my trailer today to take a look in what I can see of the keel trunk. Here's what I found: the port side keel pin plate has somehow coroded to the point that the forward bolt has slid most of the way through the plate. I went into the cabin to get a look from the other side, and it's not much prettier up there. What is the procedure for repairing such a problem and where can I find a new plate if one is needed? Thanks for the help.

another picture

Here's another picture showing how far the plate has dropped down. I think this could also be some of my leak problem.

Plate

I would take what you have to a local machine shop and simply have them make you a new one rather than trying to locate a replacement. I basically did the same thing except it was for new chainplates which I think I'll go ahead now and start a seperate thread concerning that.

Try this

Have a metalurgist at the local university look at the plate. Replace the bolts regardless. We all have your irrational fear, by the way.

better than expected

I pulled the suspect screw out today, and it is the screw that has issues, not the pin plate. Any ideas on what grade/material I should use when replacing the screws? I can get absolutely anything I need from a place called Tacoma Screw, and I have a friend in the pipe shop on the submarine base I work at. Quality is not limitted for this repair. Also, what method should I use to seal the hole once the screw is back in? And yet another question, what are these torqued to? I'm pretty sure that being loose and rocking in the bevel of the plate is what caused the damage.

underwater sealant

Is 5200 the preferred sealant for underwater hull penetrations? I've read around and haven't found anything definitive yet. From what I can tell, the PO attempted to seal the plate to the hull and sealed both the heads of the screwes and the nuts on the inside. Is this a good way to provide a water tight seal?

I use 4200 for this

when I drop the centerboard for inspection/repair I use 4200 to rebed those plates (5200 is for permanent attachment)
