As I posted in an earlier thread I am removing and patching 2 transducers thru hulls.
As I was grinding away I came to realize that in the early 80s when they put the waste treatment system in they moved the 1.5" thru hull forward and filled the old hole with green glass impregnated bondo. Attached are 2 pictures previous to my removal and grinding the thru hulls. The dark blob is about 1/2 " of bondo lump now gray in color. The edges are pretty friable, I can peal it with my fingernail.
My concern is for the center, I did not probe it but I am concerned about it popping out in the future. Is this actually a good repair?
Heck, it has lasted 30 years but with the motor out it is a good time to fix it right.
