Its 100% Solid. No movement. There is a gap as the picture shows but no failure or void in the bond. Its hard inside the gap. Feels like epoxy. There was no water inside the keel. Going back to the original issue - the slot is narrower at the opening than elsewhere and required grinding to eliminate binding centerboard. Is there a relationship between that and the gap?

After looking at the photo, I'm with Dave- is there any give if you reach up and press the trunk walls outward so that the vertical edge meets the edge of the hull? It really does looks like the hull trunk joint opened up- if you poke in the voids, what do you hit?

Ok a '92. The boat has a lead filled keel and lead filled M15 centerboard (fiberglass sell with lead shot inside).

To my eye it looks like the trunk is not lined up with the slot in the hull. There is a visible seam. The trunk should be sitting on the inside of the hull so the joint is visible inside and along the trunk, not easily see. From the bottom of the keel. See attached where I've highlighted the seam. I can also see voids in that seam (on the right side.of the image I've run some red lines representing the seam and with some purple representing the voids).
On the Facebook MSOG page SeanM has posted details on a M17 he is recommissioning. The link is to one of his posts that shows how the seam is usually aligned -

What year is your boat?

Attached is a photo of the trunk before I did anything to it. I don't have an after photo. There were no leaks or issues other than a slight
bind
when lowering the board. The only reason I was in there is for barrier/bottom paint.

The board doesn't appear to be glassed but the trunk appears to have added material at the bottom around the slot opening that reduced the clearance with the board to zero.. Original construction or later repair - unknown. It's plain to see by holding a straightedge vertically in the slot.
I sanded the material down enough to allow free board movement with 2 coats of bottom paint. I'll know tomorrow when the board is reinstalled if I'm successful. The board and trunk will not have any barrier coat since I removed it when the jammed board was discovered. A lot more material would need to be ground from the trunk to allow clearance for barrier coat.
When I first launched the boat after purchase, I noticed a slight bind when lowering the board. I thought at the time that the pennant was binding somewhere when in fact, even without bottom paint, there was interference between the trunk and centerboard.
I'd be very interested to hear Jerry's opinion.
