Leaky Gudgeon Bolts

So one of my issues I need to fix while the boat is on the hard is the "Wallowed Out" bolt holes. Looks like original from 1981.

On the inside I was considering roughing up the fiberglass, creating a dam and pouring some slow cure epoxy (Table Top Stuff - up to 4-inch pours) to "Fill the Void" back there. BAD IDEA???

I find myselfe to have a similar problem. While underway in light sailing some water find its way from the transom area into the bilge.
The only suspects are the lower gudgeon and its bolts or the bolts holding the sterntube.

Are your gudgeon bolts in the bilge/transom are? Hard for me to get a good loock since a modified diesel tank is blocking my view. And it also seems to be a solid area with epoxied play wood in between (check picture)

Or it might be the sterntube bolts, since I had them loosened last winter while installing a new prop.

Might as well reseal all of them.
I am welcome to any suggestions.

Last summer, before taking the boat out of the water, I climbed-low crawled ect to see. I removed the hot water heater which made it easier. I was thinking the packing gland but ruled that out. Next was the stern tube but once I got back there it was obvious the grudgeon bolts were the culprit. Righr now is the time to fix since the water heater is gone along with the motor. Lots of room to fix things - kinda of.

Another source might be the just above water line thru hull drains. Exposed constantly they can crack and leak. Worth checking even if they aren't the culprit. They have a 15 to 20 year life.
