Some progress over the weekend:
After the "dry" fit I took a 1/2" drill and made some shallow holes between the two pieces that were epoxied together and in the bottom of the piece that would attach to the stringer to give the thickened epoxy some "tooth".
After setting the pieces in place and a letting the epoxy set up, I glassed in the new smaller center drain tube.
Today after work, I wasn't ready to start anything inside the hull (still planning my next move) so I decided to see what I could do with the center console. I priced some new ones a while back but thought modifying the original would be more prudent than dropping a grand on a new one. The area to be removed had been marked with a sharpie a while back so all I had to do was to do was start cutting.
I removed 6" from the original which took the outside dimensions at the top from 37" to 31". I like the forward compartment for storage and have thought about putting the batteries in there or turning it into a cooler. I cut the original lid as well that is resting in the foreground.
